A variable width support system includes an adjustable width person support apparatus (PSA), an adjustable width person support surface (PSS), and first and second controllers. The first controller controls a function of the PSA and receives a first input corresponding to a function of the PSA via a first user interface. The second controller controls a function of the PSS and: a) receives a second input corresponding to a function of the PSS via a second user interface when the first controller is not in communication with the second controller, and b) receives a third input corresponding to a function of the PSS via the first controller when the first controller is in communication with the second controller. The second controller controls a function of the PSS in accordance with the third input when the first controller is in communication with the second controller.

Techniques and architectures are disclosed for power-adjustable furniture management systems and methods. The system includes a first power-adjustable furniture and a second power-adjustable furniture connected to an electrical source. The first power-adjustable furniture is communicatively coupled to a computing device. The computing device includes a processor, and a power management mode executable by the processor. The power management mode is configured to adjust the first power-adjustable furniture. The power management mode is further configured to prevent the first power-adjustable furniture from being adjusted while the second power-adjustable furniture is operated. The computing device is communicatively coupled to a server computer via the network.

A patient support apparatus includes a first transceiver adapted to wirelessly communicate with a second transceiver of a headwall interface that is positioned off of the patient support apparatus. A communication link is automatically established between the first and second transceivers without requiring a user of the patient support apparatus to activate a designated control and without requiring the user to identify the headwall interface. The first transceiver includes a unique identifier assigned to the headwall interface in its messages to the headwall interface. The first transceiver may also automatically transmit a disconnect signal to the headwall interface indicating the termination of the communication link is not accidental. The disconnect signal is sent based on one or more of the following: (1) a brake being off, (2) an A/C power cord being unplugged; and/or (3) a signal strength between the transceivers decreasing.

A method for detecting occupant position change on a support surface includes establishing a rate of change of pressure in a head end test zone and in a foot end test zone, comparing the head end rate to at least one head end rate limit, comparing the foot end rate to at least one foot end rate limit, and inferring, in response to the comparing steps, whether or not occupant migration has occurred. An associated occupant support includes a frame and a mattress. The mattress includes head and foot zones each having at least one pressurizable bladder. The support also includes a controller adapted to compare a head end rate of pressure change to a head end rate limit, to compare a foot end rate of pressure change to a foot end rate limit, and to infer, in response to the comparing steps, whether or not occupant migration has occurred.

A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a base and a patient support surface supported by the base. The patient support apparatus also comprises movable members that are movable between at least a first position and a second position. One or more rotary actuators with rotation limiting devices are coupled to each movable member. The actuator with the rotation limiting device permits drive torque to move the movable member in a desired position between the first and second positions and restricts back drive torque from moving the movable member.

The invention discloses a single motor adjustable multi-function bed, which comprises a fixed mechanism, a movable mechanism and a back panel. The fixed mechanism comprises a fixed frame, a movable rail is arranged symmetrically on both sides of the fixed frame, and one end of the fixed frame is provided with a first cross bar. The movable mechanism comprises a movable frame, a sliding part arranged symmetrically on both sides of the movable frame, a second cross bar arranged in the middle part of the movable frame, the movable rail engages with the sliding part, and the bottom of the back panel is connected with the first cross bar. And a driver is provided between the first cross bar and the second cross bar. The invention realizes the angle adjustment and the bed length adjustment function by the movable rail in conjunction with the sliding part.

A modular bed includes a base frame unit and a plurality of support frame units. Each of the support frame units includes a leading bar, a trailing bar, four mounting frames, four biasing members, a left linkage, and a right linkage. In response to loading or unloading of a retaining member of each of the left and right linkages, a respective one of the biasing members abuts against a top abutment wall or a bottom abutment wall of a respective one of the mounting frames so as to generate a counteracting force to counteract the loading or unloading movement of the retaining member, thereby providing a cushioning effect for the retaining member.
