A system for measuring data specific to a subject using gravity comprises a substrate on which a subject lies, the substrate having multiple legs extending from the substrate to a floor to support the substrate, and load sensor assemblies. Each load sensor assembly is associated with a respective leg and comprises a cap configured to receive a load from the substrate, a base configured to provide contact with the floor, the base and cap configured to fit together to maintain alignment of the cap to the base while allowing vertical movement of the cap, a load cell between the base and the cap, one of the base and cap configured to translate the load to the load cell and a printed circuit board that processes and outputs data from the load cell, wherein a combination of all load sensor assemblies receive an entire load to which the substrate is subjected.

Devices and methods for determining item-specific information for single or multiple items on one or multiple substrates are described. The method includes generating multiple sensor multiple dimensions array (MSMDA) data from multiple sensors, where each of the multiple sensors capture sensor data for one or more items in relation to a substrate. For each item, the method includes determining relationships between the multiple sensors based on characteristics of the MSMDA data, determining a location of the item on the substrate based on at least the determined relationships between the multiple sensors, determining an angular orientation of the item on the substrate based on at least the determined relationships between the multiple sensors, and determining a body position of the subject on the substrate based at least the determined relationships between the multiple sensors, the location of the subject, and the angular orientation of the item.

A bed comprises substrate support members, each including a load bearing and a base configured to provide contact with a floor. The load bearing member is configured to move vertically relative to the base, while the base and the load bearing member are configured to fit together to maintain lateral alignment of the base and the load bearing member. A load sensor is positioned between the base and the load bearing member, the load bearing member configured to transmit a load from the substrate to the load sensor. A printed circuit board is in communication with the load sensor. A controller is in communication with the printed circuit board of each substrate support member and is configured to receive and process data output by the printed circuit boards.

A mattress foundation includes: a head end panel assembly; a foot end panel assembly; a left side panel assembly; and a right side panel assembly, all slidably attaching to each other using sliding mechanisms. At least one of the sliding mechanisms includes an elongated slot and an elongated protruding element that fits within the elongated slot. A horizontal cross-section of the elongated slot and/or the elongated protruding element includes thin elongated flexible arms, attached at their proximal ends to a common surface, but otherwise extending away from such common surface and separated from each other. When viewed from the horizontal cross-section, the average thickness of the thin elongated flexible arms is substantially less than the length of the thin elongated flexible arms.

An electronically controlled slat bed includes a bed frame; slats together at least partially forming a base for a sleeping surface; struts coupled to the slats, and each strut coupled to said bed frame; jackscrews, each coupled to at least one strut to adjust the coupled strut; flexible apparatuses coupled to one of said jackscrews; a gantry coupled to said bed frame, the gantry having an electric motor; and a sensor; the motor is to engage and rotate the jackscrews; and said sensor is to provide a measurement of a deflection of the flexible apparatuses; and an electronic controller, having an input to receive signals from the sensor; and one or more outputs to control said electric motor; said electronic controller performs computations at least partially responsive to said measurement of the deflection of said flexible apparatuses and modifies the shape of said base for the sleeping surface by rotating one or more of the plurality of jackscrews; and the deflection of one of the flexible apparatuses is responsive to a weight load applied to one of the jackscrews coupled to one of the flexible apparatuses.

An electric bedstead includes a frame having first and second rods, a supporting cloth, first and second clamping members. The supporting cloth has a supporting portion, a first bending portion extending from a first lateral side of the supporting portion and attached on the first rod, and a second bending portion extending from a second lateral side of the supporting portion and attached on the second rod. The first clamping member is mounted to the first rod in a way that the first bending portion is clamped between the first clamping member and the first rod. The second clamping member is mounted to the second rod in a way that the second bending portion is clamped between the second clamping member and the second rod. As a result, the electric bedstead is lightweight to facilitate carry, storage and assembly of the electric bedstead.

A frame system that is adjustable in size and shape is provided with components that move in relation to each other. The frame system uses two main bar rails having at least one short channel piece and a housing piece. The frame system also includes two side bar rails of at least one long channel piece and the housing piece. A pair of center bar rails attach to the side bar rails and include at least one strut extension piece and a strut housing piece attached to a center leg. The corner assemblies include a corner piece to receive an end of a main bar rail and an end of a side bar rail, a corner leg, and a bracket.

A connecting structure of a bed frame is provided. The bed frame includes a frame, bed legs, and a bed plank support frame. Two side boards of the frame are provided with a plurality of support portions, respectively. One end of each of a plurality of support members of the bed plank support frame is connected to a corresponding one of the support portions of the side boards. Another end of each of the plurality of support members is connected to a corresponding one of support boards of the connecting spine. The connecting spine is designed as a -shaped structure, and the upright board is integrally formed with the support boards so that one end of each of the plurality of support members can be directly attached to the corresponding support board of the connecting spine, providing a simple structure and a stable support.

A collapsible peripheral frame includes first and second outer lateral bar units, and first and second longitudinal bar assemblies. Each of first and second longitudinal bar assemblies comprises first, second and third longitudinal bar units rotatably connected with each other at their adjacent ends. The first outer lateral bar unit has a first end connected with an end of the first longitudinal bar unit in the first longitudinal bar assembly and a second end rotatably connected with an end of the third longitudinal bar unit in the second longitudinal bar assembly. The second outer lateral bar unit has a first end rotatably connected with an end of the third longitudinal bar unit in the first longitudinal bar assembly and a second end connected with an end of the first longitudinal bar unit in the second longitudinal bar assembly.

A foldable supporting assembly includes an inner lateral bar unit, and first, second, third and fourth longitudinal bar units. The first and second longitudinal bar units are disposed at a first side, and rotatably connected with the first and second ends of the inner lateral bar unit. The third and fourth longitudinal bar units are disposed at a second side, and rotatably connected with the first and second ends of the inner lateral bar unit.
