Mattresses including spring systems sag over time and bugs especially bed bugsmites, human secretions, and other infestations and contaminants build up.

One or more of the foregoing aspects may be measured by sensors positioned throughout bed , or may be input through a computer interface, downloaded from the internet, or otherwise provided.

Physical modeling algorithms may be applied to estimate the resulting shape and orientation of a person's body due to the impact of a given bed surface shape on the skeletal structure, muscle tissue, and fatty or other soft tissue of a person's body. Computational algorithms such as finite element analysis, solid modeling computer algorithms, and other computer modeling techniques may be used to model the combined structure made up of a person , bed covering , strut caps , struts , pillow , any springs or other pliable materials or structures that may be present, any flexing or compliance of bed frame , and any other structures that may be present in various embodiments of beds or slat beds so that substantially complete and accurate modeling of sleeping positions, stress on person , and other results may be determined.

Once a substantially optimized surface shape for a bed has been determined, the bed or slat bed may provide actual adjustments to implement the shape that was determined.

Once the actual bed surface shape is applied by adjusting struts , pressure or force measurements at each strut may be assessed against the previously modeled predictions and further optimizations may be made to converge to a result. Special comfort or health modes may also be offered in some embodiments wherein certain conditions or preferences may be provided. For example, in the course of pregnancy, the weight and distribution of weight of a woman's body changes.

Some embodiments may automatically determine that the bed occupant is a pregnant woman by monitoring changes in her weight, weight distribution, preferred sleeping positions, sleep and wake habits, body temperature, heart rate, breathing, and possibly other factors and may automatically adjust sleeping contours to optimize comfort and health.

Person is shown positioned on their left side and the adjusted sleeping position and adjustment of struts may be determined according to account for the position of person's head and neck , shoulders , hips , thighs , knees , feet , and arms For such measurements, the struts of bed may be adjusted to produce a substantially flat surface so that an accurate pressure profile may be collected and person may assuming various sleeping positions while pressure profiles are collected.

Such a pressure profile may simply note which struts have pressures above some threshold or may measure and store the pressure at each strut quantitatively and with substantial accuracy and resolution. A collection of pressure profiles specific to a given person may be collected for multiple sleeping positions, so that bed may recognize these positions through mathematical correlations, or other relevant analysis techniques, when the person later assumes similar positions while sleeping.

Accordingly, person may lie on bed and assume different sleeping positions for storage and reference and then may direct bed to adjust to their position automatically. Once bed has adjusted, person may then manually control bed , through a user interface.

Once person is satisfied with how bed is adjusted, they may command bed to store those adjustments so that they may be utilized again later when person assumes similar positions while sleeping. User interfaces through which a person may control a bed to make adjustments to the shape of the surface of bed may include graphical representations of bed , and may possibly also show the surface shape of bed , that a person may interact with using a mouse, cursor controls, a touchscreen interface, or other possible computer or electronic display interfaces.

In addition to reacting to the sleeping position of a person , some embodiments of bed may provide additional enhancements. For example, struts may move in one or more direction to provide a vibrating, undulating, waving, rocking, or other sensation to person Struts may move up and down rapidly to create a vibrating effect, or may move slowly to compensate as person shifts during sleep. Some embodiments may enhance motion in such a fashion and gradually diminish the enhancement of motion over time if the person stops all motion of their own so that the bed does not sustain motion that person no longer desires.

Bed may also come to know the sleeping habits of person and may anticipate when and how person will move in bed. For example, if bed learns through observation of the habits of a particular person that they roll from one side to the other every 20 minutes during sleep, bed may adjust itself to help the person roll more easily and more comfortably fall back to sleep.

For example, bed may flatten some portions of its surface and angle others just before it anticipates that person is ready to roll so that person may roll over more easily. For health reasons, some embodiments of beds may adjust to encourage motion of person in the bed. For example, to avoid bed sores in elderly persons, a bed may encourage a person to roll to a new sleeping position every few hours.

Some persons may make inputs to bed to direct certain aspects of how they will sleep. For example, many persons desire their upper chest and shoulders to be somewhat elevated relative to their hips so that stomach acid does not enter their upper digestive tract. Such persons may also benefit from a slight increase in pressure against their lower back, upper thighs, and possible a slight elevation of the bed surface just below their feet, as these modifications may allow them to maintain their position on bed and avoid sliding over the course of a night to the foot-end of their bed Persons may provide inputs through a user interface connected to and controlling bed to provide inputs on their sleeping preferences and special needs.

Other inputs a person may make to a bed user interface might include their height, weight, age, sex, preferred sleeping positions, health factors, whether or not they have back pain, whether they have pain in other parts of their body, and other helpful information that a bed may utilize to benefit them.

Accordingly, person may have their sleeping preferences with them such that if they are travelling, they can input their preferences into a bed having similar capabilities as bed User preferences may also be virtually stored in a cloud or website, etc.

Some embodiments of bed may include electronic controls that erase or over-write personal information that may be downloaded to the bed by person after that person has stopped using the bed to protect private information, or after a specified event or lapse of time has occurred. Pressure profiles as shown in FIGS. However, other or additional information regarding sleeping position of person may be collected in other ways; for example, a camera or other monitoring device may be used.

As such, use of one or more infrared cameras, sonar, radar, heat sensors, or other techniques may be useful in some embodiments to determine sleeping positions.

In some embodiments, analysis algorithms utilized in a bed may augment a pressure profile with optical, infrared, sonar, radar, or other information to allow more precise and accurate determination of sleeping positions. Overhead images or images taken from the side from a camera, infrared camera, radar, sonar, or other imaging system from above bed may also be used in some embodiments.

For such embodiments, techniques for mounting a camera, infrared camera, radar system, sonar system, or other imaging system above bed , either on a frame, ceiling, wall, or other possible mount, may be implemented. Struts may be of similar design to strut shown in FIG. A base structure for slat bed is provided by bed frame and each slat may be supported by two struts , one near to each end of a given slat Slat bed may be adjusted so that person is supported by a contour formed by adjustment of the plurality of slats making up slat bed However, slats extend substantially across the width of slat bed so the ability to provide adjustable contours across the width of slat bed is limited, while providing adjustable contours along the length of slat bed is readily achieved.

Slat bed comprises a plurality of slats , motion sensors , temperature sensors , lugs , springs , and bed frame Bed frame has top surface and struts are supported inside bed frame Struts may be supported similarly as described hereinabove in conjunction with FIG. Struts are shown emerging above the top surface of bed frame from fittings Fittings may be used in some embodiments and may be threaded inserts into top surface , may insert into top surface in other ways, or may be simply affixed to top surface The covering or shroud may be flexible, telescoping, may use a fan-folded construction, or may be otherwise configured so that it may compact and extend accordingly.

Fitting as shown in FIG. As bed frame may contain electrical equipment, some embodiments may comprise water impermeable coverings, shrouds, or fittings may be used to avoid the potential for electric shock if liquids are spilled onto a bed such as slat bed Fittings may extend above top surface of bed frame to prevent liquids from pooling near struts In some embodiments, top surface of bed frame may be slanted or otherwise designed so that water or other liquids spilled onto top surface flow from top surface and don't pool there.

As top surface may be designed to facilitate air flow, some embodiments of top surface may be configured to repel liquids and also be air permeable. Slats and shrouds or sleeves covering struts may also be electrically insulated. Slat as shown in FIG. Other embodiments of slat beds may make use of slats that are longer than bed frame is wide so that thicker ends extend beyond bed frame on either or both sides of bed frame Still other embodiments may make use of bed frames that are wider than slats are long.

Embodiments of slats on slat beds may not be all of the same length so that some slats may extend beyond the sides of bed frame , some slats may align with bed frame , and still other slats may be shorter than bed frame is wide. Slat may have a thinned central region that allows slat to be somewhat flexible and pliable to the weight load of a person that may lie on a slat bed Slat may have a thicker end to facilitate connection to struts and to provide a smooth and rounded structure over which a bed covering similar to bed covering or may be applied.

Some embodiments of slats may include lugs that allow slats to mechanically couple to adjacent slats and possibly also to a head platform , foot platform , or other structures that may be found in some embodiments of slat beds As will be shown in FIG.

Lateral stress on slats may occur as a person climbs onto slat bed , rolls over while sleeping, or moves while they are supported on slat bed In some embodiments, slats may be made of pliable materials that flex when weight is applied to them.

Struts are connected to slats with pins that may be placed through the upper ends of struts and through slotted holes in slats The upper end of struts may contact springs that may be supported inside coupling holes in slats Springs in slats may take the place of and perform similar functions to springs shown in FIGS.

Slats may flex along central region and may also be pliable due to the presence of spring or the presence of other flexible or pliable materials. Further, a bed covering applied over slats may offer further compliance and comfort to a person laying on slat bed The application of pins inside slotted holes to connect slats to struts in some embodiments may allow springs to be compressed or extended and may also allow sufficient motion between slats and struts so that left slat height and right slat height may be different this is shown in FIG.

Adjustment of struts may allow slats to be positioned so that their top surfaces may not all be parallel. While the connection between slats and struts utilizes pins and slotted holes , those skilled in the art will recognize that embodiments utilizing sleeves, bushings, bearings, ball bearings, roller bearings, thrust bearings, ball-joints, alternative fittings, catches, clips, snaps, cams, bolts, nuts, washers, roll pins, inserts, and other mechanical connection techniques are also possible.

Likewise, some embodiments of slats may lack springs and struts may be fixedly attached to slats in some embodiments, or may pivot but not provide spring action or compliance. Struts and slats may comprise pliable materials such as plastics, foam rubber, or other pliable materials used in place of springs to create an adjustable mounting of a strut to a slat Embodiments of slats are also possible that include a threaded connection to a jack screw of a strut in place of using a threaded connection to an upper support as shown in FIGS.

A motion sensor may be present in some or all of the slats In some embodiments, motion sensor may be an accelerometer, or other sensor capable of sensing motion of slat so that electronic circuits in slat bed may sense the motion of a person lying on slat bed Motion sensor may be used to sense a heart rate or breathing rate of a person lying on the bed. Bed may further comprise sensors, accelerometers, microphones, and other sensors that may allow the bed to monitor, record, analyze, and provide control to the struts , temperature controls, or other available controls based on a person's breathing, heart rate, and other measurements related to the person's health and condition.

Some embodiments may record health data and may even signal alarms if certain health conditions occur such as heart rate conditions that signal the onset of a heart attack, for example. Temperature sensor may measure temperature as close as possible to person The output of temperature sensor may be used to control heaters, coolers, fans, and possibly other elements of some embodiments of slat bed Like bed , slat bed may have similar components and capabilities to monitor and adjust temperature at one or more times while person is in slat bed Motion sensor and temperature sensor are connected to electronics inside bed frame by sensor wires In some embodiments, sensor wires or other electrical wires running from slats to bed frame may be bundled together, shrouded, pass through articulating or telescoping conduit, pass through shrouding or conduits that also shroud struts , or utilizing other techniques.

Embodiments of slats shown in the present disclosure are rigid or semi-rigid per above, some embodiments of slats may flex under load members consistently shown supported by two struts Alternative embodiments of slats are possible that may comprise two or more rigid or semi-rigid members supported by a greater number of struts.

For example, if three struts are used, a slat consisting of two rigid or semi-rigid members with a pivot, or other articulating joint connecting them may be supported at both ends by struts and at the pivot or other joint by a third strut.

A rigid or semi-rigid single slat may also be supported by three or more struts. For example, an embodiment of a slat bed may be configured for very large or heavy persons and may benefit from slats that are supported by more than two struts each.

Bed comprises an electric heater embedded in slat The view of FIG. As shown, left slat height is longer than right slat height so that the top surface of slat is downward to the right.

Positioning slats in a tipped position may allow some embodiments of slat beds to provide a rocking or undulating motion that may be desirable for rocking a person to sleep, massaging a person whether or not they are sleeping , or otherwise providing desirable motion or positioning of the slats For example, some persons may benefit from having their knees slightly lower than their hips while sleeping on their side; or possibly having their arms and hands slightly lower than their head.

Heater is embedded in slat and may be connected electrically to a control circuit, driver, or other source of electric power through heater wires Slat may contain a temperatures sensor so that heater may be controlled to achieve a desired temperature or heater may be controlled in an open loop fashion through direct control by a person lying on slat bed Embodiments of slat bed may utilize slats that all contain heaters or in which only some of the slats in the bed contain heaters.

For example, some embodiments of slat bed may only use slats with heaters in the region of slat bed where a person's feet may be present. The embodiment of slat shown in FIG. Slat end is rounded so that a bed covering, such as bed covering , may be stretched over the slats of slat bed and be fitted with a draw string or elastic band.

Some embodiments of bed coverings may also be attached to slat beds with elastic bands that run in parallel to and between slats and pull the lower edges of the bed covering together so that the lower edges of the bed covering are substantially pulled tightly into notched regions by the elastic bands.

That is, these elastic bands would attach to a bed covering near the left side notched region and near to the right side notched region shown in FIG. Hook and loop fasteners, snaps, pockets, clips, pins, or elastic bands or other techniques may be applied on slat in the notched region where slat end meets the region where struts connect to slats The bed covering may be attached to every slat of a slat bed or may be only attached to a subset of the slats in a slat bed While a uniformly thinned central region is shown in FIGS.

Other embodiments of slats with non-uniform thickness and that react to weight loads in desirable ways are clearly also possible. While the top surfaces of slats shown in FIGS. Slats may also not all be of uniform shape and some embodiments of slat beds may utilize slats optimized for back support in the region of a slat bed where a person's back may normally lie and slats optimized for support of other portions of a person's body where those portions may normally lie.

Slats may be designed to be substantially easy to remove and install so that they may be interchanged, replaced, or removed to customize slat size and configuration according to person's preferences or body type. Embodiments of slats may be designed to be rigid, to be flexible, to flex different amounts in response to applied weight, to have hollowed out sections to control flexing, to incorporate combinations of materials to control flexing, to be of different shapes so they flex in desirable ways, to have differently contoured top surfaces, to have top surfaces that include bumps, ridges, or other features to provide a massaging action, to have top surfaces that are padded or pliable, to incorporate springs of various levels of stiffness, or to be otherwise tailored to provide beneficial effect for a person utilizing slat bed As shown in FIG.

Lugs may be configured in various shapes, including, but not limited to trapezoids, dove-tailed, round, or other possible cross-sections. Referring to FIGS. In some embodiments, the vertical height between adjacent slats may also be limited with mechanical stops, computer control algorithms, or through other techniques for safety reasons, so that hands, feet, or other body parts may not extend over one slat and under an adjacent slat in the course of utilizing a slat bed The spaces between lugs and between lugs and slats may contain nylon, felt, fabric, plastic spacers, pliable materials, or other bushing material to allow lugs to interlock smoothly while slats are raised or lowered when struts are adjusted.

Lugs may provide benefit to some embodiments in interconnecting slats so that stress applied to them is absorbed by multiple slats and struts Those skilled in the art will recognize that alternative mechanical techniques to interconnect slats besides the use of lugs are possible.

For example, slats may include interconnecting members to adjacent slats ; slats may be buffered from each other with felt, rubber bumpers, or other pliable elements; slats may be coupled with layers or webbings of nylon, plastics, metals, canvas, fabrics, or other materials affixed to their top or bottom surfaces; or other techniques may be applied.

In some embodiments, a bed covering similar to bed covering may be affixed to a bed or slat bed in a manner so that the physical properties of the bed covering couples slats together.

For example, if the bed covering is affixed to slats with hook and loop fasteners affixed to the top of slats and the underside of the bed covering, the hook and loop fasteners connection may serve to couple slats together and provide a strengthening effect as the slats may bear lateral force applied to them acting together.

Some embodiments of slat bed may utilize canvas, nylon webbing, or other materials to bind only a limited number of the end-most slats on slat bed together. Individual struts in bed may also be bound together through the use of meshes, canvas, or the application of bed coverings affixed to struts so that the struts may act together robustly in the face of laterally applied stress.

As slats are raised, lowered, and possibly tipped, it is possible in some embodiments for lugs to compress against each other and to possible bind or interfere in an undesirable way. Accordingly, applying a control algorithm for the adjustment of struts to first level slats may prevent or reduce binding or compression between lugs Slats may then be raised or lowered as desired, and then slats that are desired to be tipped may again be tipped into their desired positions.

Slats may be substantially relieved of binding due to tipping by leveling them as an initial step , adjusted vertically, and then tipped back into place in a recursive manner as slats are adjusted over time in the course of operation of a slat bed Some embodiments of lugs may employ mating surfaces that are slightly rounded or contoured, larger gaps between lugs that may also include thicker applications of pliable or bushing materials, larger gaps between lugs and slats that may also include thicker applications of pliable or bushing materials, or other features, finishes, designs, or construction that substantially reduce binding between lugs as slats are adjusted in position.

Internal stabilizers may be a board, member, or other structure that is secured to bed frame and extend upwards between slats so that the structure of internal stabilizer engages lugs so that horizontal motion of slats is substantially stabilized. Lugs and slats may slide over the surfaces of internal stabilizers so that vertical motion of slats and lugs is not blocked, but lateral or horizontal motion of lugs and slats is stabilized.

Internal stabilizers may be utilized between every pair of slats in some embodiments, may not be present at all in some embodiments, or may only be present between some pairs of slats Internal stabilizers may comprise wood, plastics, metals, and other possible materials and may be laminated, coated, or treated with coverings of felt, plastics, lubricants, or other materials to benefit smooth engagement and sliding against lugs and slats In some embodiments, internal stabilizers may be sized and shaped for minimum impediment to lateral motion of the lugs against the ends of internal stabilizers or may be sized and shaped so they only impede lateral motion of the slats against the sides of internal stabilizers.

External stabilizers perform a similar function to internal stabilizers , but are simply mounted to bed frame and positioned so they act on the outside of lugs versus between lugs as was the case for internal stabilizers Those skilled in the art will recognize a very wide range of possible constructions for additional stabilizers that may be formed with levers, connecting members, sliding members and other possible constructions to stabilize lateral or horizontal motion of slats in a slat bed Lugs , internal stabilizers , external stabilizers and other possible structures that may interface with each other as a slat bed is adjusted may result in rattles, noise, and other effects if they do not fit well together.

Some embodiments of slat bed , may employ shims, adjustable fittings, spring loaded gliders, spring loaded plates, hydraulic cylinders, pneumatic cylinders, pliable materials, or other possible techniques between slats , lugs , internal stabilizers , external stabilizers , and other associated structures to improve fit and substantially avoid rattles, noise, vibrations, or other possibly undesirable effects.

Rounded corners may reduce pressure from sharp corners that may protrude over the course of a contour adjusted to fit a given person and accordingly improve comfort. Internal stabilizer and external stabilizer are shown mounted to a portion of bed frame and extend upwards between pairs of slats In most embodiments, the top surface of internal stabilizers and external stabilizers may be kept somewhat below the top surface of slats so that the sleeping surface is determined by slats and not by stabilizers protruding between them.

Slats having mushroom shaped top surfaces or other rounded and extended top surfaces may further improve comfort in the fashion of rounded corners Some slats may also use top surfaces that are padded, coated with rubber, covered with layers of leather, canvas, or other materials, or are otherwise covered, coated, or laminated with materials or combinations of materials to improve comfort or provide other benefits.

The extension of mushroom shaped top surfaces to slats may reduce the amount of air flow that is possible through slats In response, some embodiments of slats may be perforated, or mushroom shaped top surface may be formed from a mesh of metal, a plastic mesh, materials that allow air to flow through them, or other materials or configurations to benefit the free flow of air.

Also, some embodiments of slats may utilize one or more different formations and combinations of top surfaces. For example, mushroom shaped top surfaces may only be utilized along some portion of the length of a slat and other shapes or constructions may be utilized along other portions of the length of slat Pliable top member may be formed from rubber, plastics, wood, metals, laminated materials, or other suitable materials and may be formed in manufacturing with slat or may be bonded, glued, riveted, screwed, nailed, or otherwise affixed to slat In some embodiments, slats may have a reduced width along their top surface so that pliable top members may flex more freely.

Pliable top member may allow slats of different heights to form a smoothly flowing contour to fit a person and avoid the protrusion of sharp edges that may cause discomfort. Pliable top member may be perforated, formed from a mesh or grid of material, or otherwise formed or configured to allow the free flow of air.

Pliable top members in FIG. In some embodiments, pliable top members may actually extend over complaint top members of adjacent slats and overlap or interlock. Those skilled in the art will recognize many possible embodiments. The two right-most slats shown in FIG. Those skilled in the art will recognize that many common mechanical constructions such as roll chains, bulldozer tracks, military tank tracks, and other constructions allow stiff members to be interconnected to form a mechanical device or element that may be fitted to a contour.

Such constructions may be adapted to the interconnection of slats Interlocking members may be applied at regular intervals over the length of slats to benefit comfort.

It is also possible to laminate or otherwise affix nylon or plastic meshes, fabrics, nylon webbing, webs made from other suitable materials, canvas, or layers of other suitable materials over all or limited parts of the top surfaces of the slats forming a slat bed to benefit the ability to generate smooth contoured surfaces.

While lugs are shown in FIG. The two right-most slats in FIG. Top pieces may couple to slats with pins that extend the full length of slats in the manner of a long hinge, so that pins alternately couple to top pieces and slats in intervals along the length of slat Top pieces may interlock with slats , couple through channels in top pieces that pivot over a fulcrum formed along the top of slats , or may be formed and adjoined through other possible techniques that allow a top piece to pivot on a slat Top pieces may be attached to slats with pins as shown in FIG.

Top pieces may be formed from wood, plastic, pliable materials, rubber, metals, or other suitable materials, and may include ventilation holes to facilitate air flow. Alternative embodiments may utilize pliable connections or other possible constructions between top pieces and slats so that top pieces may rock, tilt, or pivot on top of slats Those skilled in the art will recognize many ways for top pieces to be affixed or mated to slats including canvas or fabric hinges, metal hinges, pliable mountings, or other possible constructions.

Top pieces may support and align with a bed covering such that the bed covering pressing against top pieces may serve to cause top pieces to pivot so that they freely aligned to the contour of the bed covering. In some embodiments, a mix of rigidly fixed and pivoting top pieces may be used as some regions of a slat bed may normally have a flatter surface and other regions may have more significant contours.

Additionally, there may be some regions of a slat bed , such as the slats nearest to a foot platform or head platform , where slats may not have top sections that tilt or pivot in some embodiments. End slat may be used at one or both ends of bed End slat includes extension that provides an extended surface over which a bed covering may be affixed.

Those skilled in the art will recognize that an extension or other suitable feature on the end-most slats of a slat bed may include special shapes, features, hooks, clips, snaps, hook and loop fasteners, or other features so that a bed covering may be more easily applied to slat bed End slat may comprise square edges and corners, or may also comprise additional shapes and corners that are rounded or contoured.

In some embodiments, end slat may be designed to be stronger or stiffer than other slats as end slat may need to withstand more lateral forces applied to it in the operation and use of a bed. In some embodiments, struts utilized to support an end-most slat of a slat bed, such as end slat , may be of stronger or more robust design than other struts in a slat bed In some embodiments, end slats or other end-most slats of a slat bed may be supported by more struts than other slats so that the end slat or other end-most slat is stronger and more robust.

In some embodiments, struts supporting slats , end-most slats , or end slats may be designed and constructed to be flexible in nature so that they may bend somewhat due to applied lateral forces and spring back into position when such lateral forces are removed. In some embodiments, end slats may be rigidly fixed in place or may be manually adjustable in height so that such end slats may be strong and robust without the need for stronger or additional struts Some embodiments may comprise an identification sensor to determine the presence and properties of a bed covering.

For some such embodiments, if no bed covering is sensed, the slat bed may keep the struts in either a nominally safe position or keep struts in their currently present positions as a matter of safety. Identification sensor is shown as a spiral of wire that may be electrically driven and sensed so that a corresponding identification tag that may be sewn, glued, embedded, clipped, or otherwise affixed onto or into a bed covering may be electronically sensed and read by electronics controlling and sensing identification sensor Those skilled in the art will recognize that many commonly used RFID tags are inductively driven and sensed and that an appropriately designed inductive spiral or coil of wire such as identification sensor may be used to both stimulate and sense an RFID tag in or on a bed covering.

Identification sensor may be exposed as illustrated, or covered with a protective covering, embedded inside end slat , or otherwise protected, encased, or enclosed. Some embodiments of identification sensor and associated RFID tags may be positioned proximate sensor and tag for placement of identification sensor on a slat such as end slat , and the placement of an RFID tag in or on bed covering may need to be controlled.

In other embodiments, precise alignment or close proximity may not be required and identification sensor may be placed in other locations. Those skilled in the art will recognize that some embodiments of RFID tags may be designed so they are fully enclosed in plastics or other materials so that they may withstand normal use, laundering, submersion in water, and other conditions that a bed covering may be subjected to.

An RFID system or other suitable electronic identification system for a bed covering may provide information on the thickness, stiffness, compliance, physical modeling parameters, heat insulation properties, air flow properties, and other properties that a bed or slat bed may utilize to benefit various aspects of the use of such a bed or slat bed It is possible to utilize other electronic tags or identification techniques besides RFID such as resonant circuits, optical tag readers and tags, ultrasonically coupled readers and tags, infrared light tags and readers, and any other suitable electrical, optical, mechanical, or other suitable scheme in which information regarding the properties of a bed covering may be determined by a bed or slat bed Some embodiments of beds or slat beds may be capable of measuring information from multiple layers of bed coverings so that the effects of multiple layers of bed coverings applied to a bed or slat bed may be accounted for in bed shape modeling, or for other purposes.

Some embodiments of beds may also send a signal, illuminate a warning light, or otherwise provide an audible, visible, or other indication that a bed covering is not detected to be properly installed on the bed. Pressure profile may be stored graphically and utilized in a computer that is part of the control electronics of a slat bed or the information substantially provided in FIG.

As explained previously, the pressure due to weight applied to a bed may be monitored at each strut either with sensors, such as pressure sensor shown in FIGS.

The pressure profile of FIG. So in FIG. Weight center line may be computed for each pair of struts opposite each other on the top and bottom of the view in FIG. As each slat is supported by two struts , and considering the load on each slat as an equivalent point load at some point along the length of the slat , with knowledge of the pressure or force applied to each strut and the dimensions and geometry of the struts and slat , it is possible to compute a point on the slat at which the equivalent point load is applied.

Interpolation, spline fitting, or other suitable mathematical curve fitting of these equivalent point loads for each slat in a slat bed allows weight center line to be generated.

Additionally, the total weight applied to a slat may be computed as the sum of the weight born by each strut as evidenced by the pressure or force applied to each strut , so both the location and the amount of an equivalent point load on each slat may be computed.

Weight center line provides the locations of the equivalent point loads and the circles along weight center line represent the weight applied to those equivalent point load locations, with the diameter of each circle corresponding to the weight applied.

The left-most circle in FIG. The right-most circle in FIG. In between, there are circles corresponding the knees , upper thighs , hips , shoulders , and some additional locations that have not been numbered as they are not specifically needed in the description provided here.

In some embodiments, all or only a portion of the struts may be monitored for pressure or force and so some embodiments may use more or less information to compute weight center line and the circle sizes corresponding to the weight loads on each slat Providing both a weight center line and information on the total weight load along the weight center line may help determine sleeping position.

For example, the pressure profile shown in FIG. However, persons sleeping on their backs normally press more strongly on their upper back, hips, and feet; while persons sleeping on their front side normally press more strongly on their stomachs, knees, and chest.

Hence, while analysis of weight center line alone may not allow a person sleeping on their back or front to be distinguished, analysis of weight load along weight center line may allow a front sleeper or a back sleeper to be determined. Some embodiments of slat beds may also measure the weight distribution of a person lying on the bed while measurements are recording in known sleeping positions that may later be reference and analyzed so that a given pressure profile may more accurately indicate sleeping position.

Note that the pressure profiles shown in FIGS. Weight center line as shown in FIG. A computing device comprising bed may utilize information regarding the pressure or weight applied to some or all of the struts in a slat bed and may determine information regarding the height, weight, weight distribution, sleeping position, and other factors regarding a person sleeping in a slat bed Algorithms used for such an analysis may include correlations of a weight center line , correlations including distribution and amount of weight of equivalent point loads along such a weight center line , the shape of a weight center line , and other factors.

Hence, for situations where more than one person may sleep in a given bed on different occasions, it may be possible to identify which person is present and to control the bed to their preferences, sleeping patterns, and possibly other factors.

As previously mentioned, heart rate, breathing rate, and possibly other health factors may also be assessed from pressure sensors, motion sensors, analysis of the pressure on struts , microphones, or possibly other sensors that may be present in some embodiments of beds or slat beds Personal characteristics such as heart rate, breathing rate, and other factors that may be measured by a bed or slat bed may also be used to help identify the occupant of the bed.

Such an adjustment may be uniformly applied along person's back or a somewhat larger adjustment may be made near the small of person's back to further enhance support and comfort. Slightly elevating the ends of slats below the hips and behind the thighs and slightly lowering the ends of slats in front of the thighs may shift some pressure to the backs of person's thighs and buttocks and off their pelvic and thigh bones.

Access to computer networks may also allow some embodiments of slat beds to report the need for maintenance, report operational issues, download upgrades, download updates, upload and download user information, and to otherwise exchange information and benefit from access to a computer network. When two or more persons may occupy or attempt to occupy a bed or slat bed , rather complex and difficult to analyze pressure profile may result, especially when the two or more persons are moving or changing positions.

Bed or slat bed may also be configured to a person having special physical needs, such as disability, injury, or sleeping in a very unconventional position. Accordingly, bed or slat bed may be configured for only manual position adjustment wherein the person or person's care giver may manually input an adjusted position of the bed. In some embodiments, it may also be possible for a bed or slat bed to discern that two persons are in the bed and to determine to adjust the bed for one of them only.

For example, if a child is determined to be sleeping with an adult, the bed may determine to adjust the bed for the adult with the understanding that a small child is lighter and more limber and may be less sensitive to the contour of the bed surface. It is also possible for embodiments of a bed or slat bed to mimic a conventional spring mattress which may also be useful if the sleeping position of a bed occupant can't be determined.

For example, if a bed or slat bed makes adjustments so that the force on each strut or slat is a function of how far that strut or slat is below the height of the highest struts or slats , the effect of the spring constant of a conventional bed spring will be substantially replicated, so that similar sleeping positions to those of a conventional spring mattress may be realized.

In some such embodiments, adjustments may be possible for a bed occupant to select softer or firmer bed. Like numbered elements in FIG. In some embodiments of beds and slat beds , the pressure or force applied to all struts may not be continuously monitored to conserve power, or in the case of embodiments where motor motion and current level is monitored to determine applied torque, it may not be beneficial to continuously drive struts up and down to assess applied load as this could disturb a person sleeping in the bed.

Accordingly, some embodiments of beds or slat beds may comprise a number of sensors applied to struts , or possibly to other locations such as motion sensor as shown in FIG. Continuously sensed struts may be a part of a plurality of continuously monitored sensors for such embodiments. In some embodiments, continuously sensed struts may be deployed in the region of a bed near to where a person's hips, mid-section, or shoulders may be present as greater Bed Slat Fasteners Us motion and more easily sensed signals may occur in such locations of a bed.

Some embodiments may include a greater number of struts that may be continuously sensed so that the locations of continuously sensed struts may be adaptive to a person or a Bed Slat Fasteners 60 sleeping position of a person in a bed. In some embodiments of beds or slat beds , additional sensors may be monitored in situations where movement, changes in distribution of weight, or other indications are made through monitoring continuously sensed struts or other continuously monitored sensors.

That is, analysis of sensors or struts that are continuously monitored may trigger broader analysis of sensors, motor torque, and other factors when suitable conditions are determined through analysis of the continuously monitored sensors or struts Accelerometers, motion sensors, pressure sensors, and other sensors may also be used in bed or slat bed to sense commands or signals from a person lying in the bed.

Signal sensed struts are shown in FIG. Signal sensed struts may include pressure or force sensors that provide fast response times, more bandwidth, more accurate signals, or provide other benefits versus other pressure or force sensors used on other struts so that the action of a person bumping, tapping on them, or otherwise sending signals to a bed may be assessed.

For example, if person wants the bed to begin vibrating, the person may bump one of the signal sensed struts with their hand or fist rapidly three times in succession. A signal to the bed to stop vibrating may be delivered with two bumps in succession. Hence, a simple code, perhaps similar to the well-known Morse Code, may be provided.

Such codes may signal to a bed that the person lying on it may want to the bed to vibrate, to stop vibrating, to undulate slowly, to stop undulating, to accommodate them with more back support, to raise or lower their head, or to accommodate them in any other possibly way for which such a code may be developed.

Such a code may include analysis of the timing of bumps or taps, the level or severity of bumps or taps, where such bumps or taps are applied, or other possible aspects of how a person lying in a bed may bump, tap, or otherwise provide a signal to a bed. The ability to interact with a bed by bumping, tapping, kicking, thumping, or otherwise providing a signal to the bed may enable the person in the bed to provide a signal to the controller without substantially changing position.

For some embodiments, the meaning of signals delivered by a person to a bed may have different meaning based on the sleeping position the person is in. For example, a person lying on their side that sends a signal to rock the bed surface gently may initiate a different sequence of motion of the bed surface versus a person lying on their back who sends the same signal.

That is, a bed may analyze a command from a person in view of the sleeping position of the person, the person's personal preferences, and other information the bed may have available and provide an optimized response based on the available information. Various embodiments of beds and slat beds may make use of signal sensed struts or possibly with additional or supplemental motion sensors, pressure sensors, force sensors, or other possible sensors that may be used to sense bumps, taps, or other possible signals from a person.

Signals may also include bumping, tapping, kicking, or otherwise stimulating sensors such as signal sensed struts to signal a sleeping position to the bed. For example, two quick bumps delivered near the signal sensed strut on the left side of the slat bed used to generate the pressure profile in FIG.

Bumping both signal sensed struts at a substantially identical time might signal the bed occupant is sleeping on their back. In some embodiments, a bump to a signal sensed strut may simply signal to the bed that the present sleeping position it is providing is not comfortable and should change. Algorithms in the computing device or controller that adjust sleeping position may then assume the prior analysis of the one or more bed occupants' sleeping position is not correct and move to the next closest estimate the bed has and try that one in an attempt to better serve the bed occupant.

However, other or additional information regarding sleeping position of a person on a slat bed may be collected in other ways, such as cameras, imaging devices, and other tools discussed hereinabove. Pressure sensors may not normally all read force or pressure consistently, so the operation of a bed or slat bed may benefit if some calibration is performed. In some embodiments, the reading of pressure sensors may be compensated by taking readings when the bed is not occupied.

Such pressure sensor calibration cycles may be undertaken automatically, may be done in a calibration phase that may occur when a bed is first constructed or set up for use, or may be manually initiated. Calibration may be done when the bed is known to be unoccupied and a user controlling a calibration may be directed through a user interface to clear the bed of all bed coverings and other possible loads that may affect the calibration cycle.

Some calibration routines may benefit from a bed covering in place so that any inconsistencies in the thickness, fit, or applied pressure due to the bed covering may be accounted for in the calibration.

In some embodiments, a user might be directed to apply weights to some areas of a bed sleeping surface so that reference readings under load may be taken to augment calibrations and to possibly later move the weights to other regions of the bed for additional readings.

As techniques of calibration of weigh scales, pressure sensors, and force sensors are well-known to those skilled in the art, the details of how calibrations may be performed and applied are taken as understood and will not be provided herein. Some embodiments of pressure sensors or other suitable pressure or force sensors may provide acceptably consistent measurements of pressure or force possibly after a calibration cycle , but may not provide highly accurate measurements.

For such situations, bed or slat bed may proceed with optimization of its sleeping surface based on information is available about the bed occupants actual weight. In some embodiments, a bed occupant may enter their actual weight manually through an electronic interface so that such a bed may better accommodate their comfort and health.

In some embodiments, a bed occupant may input information about their comfort while using the bed and may indicate if the bed feels too firm, too stiff, too soft, or has other limitations that a bed or slat bed may improve upon through electronic computer algorithms and controls once the limitation has been input by the bed occupant. In some embodiments of slat beds , some slats may be at substantially different heights from their adjacent slats.

This may occur, for example, with slats that support a bed occupant's hips or other portions of the body that may curve abruptly and benefit from a rapidly curving bed surface.

Readings of the pressure or force on slats in regions of a bed that have a substantially rapidly curving surface may suffer some error as the action of a bed occupant's body may place considerable lateral force on slats in those regions of a bed.

Hence, some embodiments of slat beds may benefit from compensation of the force readings of slats in regions of the slat bed where slat height varies significantly between adjacent slats Such compensations may be made based on the total weight born by a grouping of slats and a prediction of natural curves and distribution of weight of the human body. For example, weight readings near the hips of a bed occupant may be substantially similar for three slats near the hips; so a correction algorithm may assume that lateral pressure on the slats is effectively binding them together possibly through action of lugs that couple them so that they share the weight load applied to them evenly versus providing a correct reading of their individual loads.

The slat bed electronics may then decide to distribute the total weight readings of these three struts in a more natural way across them to reflect a more reasonable prediction of how weight is actually distributed. Many possible compensation or correction algorithms may be applied that take account of the force, pressure, or weight on each slat, the relative heights of the slats, modeling of the bed occupants body, and many other possible factors to provide improved readings of the load born by each slat Buttons as shown in FIG.

Buttons may be recessed from the surface they are applied to so that they may be less likely to be inadvertently pressed.

Buttons are also shown in FIG. Buttons may also be placed in various other locations. Microphone may sense voice commands from a person.

Speaker may provide information to a person in the bed regarding the time of day, their health information such as heart rate, etc. Speaker may also provide alarm functions and signal a person to wake up. Wake up signals may also be provided at programmed alarm times to a person by vibrating the struts in a bed, undulating the bed, or providing other types of motion through control of struts to signal to a person that it's time to wake up.

Some embodiments of bed or slat beds may collect information or receive information from other sources such as the internet, computer servers, social media, and other sources about the identified person's preferences and interests and may adapt information it provides to the person based on that information. Hence, a person identified and known to enjoy classical music may be provided a wakeup signal from speaker delivering classical music.

A person with keen interest in certain company stock prices may receive information about those companies before they fall asleep at night. As another example, a person with relatives in India may be awakened at night to be told that an earthquake has struck a village near where their family lives. Similarly, the detection of a house fire, severe weather, or other emergency situations may justify waking a person in the night.

Those skilled in the art will recognize that the ability of some embodiments of a bed or slat bed to identify a person and provide information and possibly other services to them, including information related to their interests, family ties, financial investments, travel interests, product interests, advertising information they may find interesting, product offerings, music, games, entertainment, and other possible information or services may provide benefit to some persons.

Additionally, some embodiments of a bed or slat bed may sense or determine when a person is about to fall asleep and may no longer desire information to be provided to them, when they are awake in the course of the night and may appreciate receiving some information, when they have awoken in the morning and what information they may find interesting, when some news or other information is so important to them that they should be woken immediately, when some news or other information is of sufficient interest that they should be provided it once they awake in the morning, or other possible ways in which various embodiments of beds or slat beds may provide information or services to a person.

A person controlling a bed or a slat bed may want the bed to quickly provide a surface that is substantially flat or is some other pre-defined shape. Larry H.
