A computer system for identifying a posture adopted by a subject is disclosed. The computer system includes a computer processor that is configured to execute the following functions: obtain a set of reference pressure images, each of the reference pressure images associated with a known posture; obtain a recorded pressure image of the subject; compare the recorded pressure image of the subject with a candidate pressure image from the set of reference pressure images; and repeat the comparing function until the recorded pressure image with the candidate pressure image.

An example method includes capturing images using a camera and detecting a medical device in a first image among the images. A request is transmitted to the medical device. Based on transmitting the request, the example method includes determining that the medical device has output a chirp signal in a second image among the images. Based on the chirp signal, the method includes causing the medical device to perform an action by transmitting a control message to the medical device.

A safety device used in conjunction with a vehicle wheelchair lift, having a mounting plate for securing to the floor of a vehicle, upright members disposed on opposite longitudinal ends of the mounting plate, a barrier plate in overlying relationship to the mounting plate and pivotally connected to the uprights for movement between a raised and lowered position, the barrier plate, when raised, acting as a physical barrier to prevent a wheelchair from rolling across the mounting plate, and an actuator operatively connected to the barrier plate. In one embodiment, the upright members are a housing and a support wall. In another embodiment, the uprights are elongated members and include a cross bar disposed horizontally and in spaced parallel relation to the mounting plate when the barrier plate is raised and is disposed vertically and transverse to the mounting plate when the barrier plate is in the lowered position.

An integrated and autonomous mobility system for disabled persons including an automated wheelchair (AV) and an Adapted Automated Vehicle (AAV) configured to work together as an integrated unit to transport a user to a pre-selected destination with little to no input from the user during the trip. The AV is also configured to operate independently of the AAV to transport the user on shorter trips, or to continue a journey after the AAV has transported the AW to an intermediate destination. Multiple safety systems are included. The system has an override function according to which a user can interrupt the automated transport operation and cause the AV and/or AAV to stop, slow down, speed up, or change direction.

A bed base frame assembly of a bed generally comprises a base frame, a plurality of steerable and lockable casters, a lateral support assembly at the first and second sides of the base frame assembly, and an in-line support assembly at the foot end of the base frame assembly. The lateral support assembly may further include: a base frame; a first leg and a second leg rotatably connected to the base frame; a first actuator connected to the first leg and the second leg, wherein the first leg and the second leg rotate from the retracted position to the extended position; a third leg and a fourth leg rotatably connected to the base frame; and a second actuator connected to the third leg and the fourth leg, wherein the third leg and the fourth leg rotate from the retracted position to the extended position.

A cover system for selectively blocking insertion of unauthorized objects through an aperture of a restraint mount of a patient support apparatus is provided. The cover system includes a cover and an instrument having an interface. The cover includes a brace and a restrictor coupled to the brace. The brace attaches to the patient support apparatus adjacent to the aperture and the restrictor operates in a restrict mode blocks access to the aperture and a permit mode where the restrictor permits access to the aperture. The cover also includes a lock mechanism, which includes a keeper movable between a locked state where movement of the restrictor is inhibited and an unlocked state where movement of the restrictor is permitted. The keeper moves from the locked state to the unlocked state in response to selective engagement between the interface of the instrument and a receiver of the lock mechanism.

An apparatus for updating a controller for a mobility device includes a communication device that receives information associated with updating one or more controllers included in the mobility device, transmits the information associated with the updating to a terminal of a user or an interface of the mobility device, and receives information about an update preference of the user based on the information associated with the updating from the terminal of the user, and a management device that generates at least one of whether to update the one or more controllers or an update sequence of the one or more controllers, based on the information about the update preference.

A patient support apparatus is provided with selective stiffening features. The patient support apparatus may include a support substrate defining a patient support surface. The support substrate may include a magnetorheological material providing selective reinforcement support of at least a portion of the patient support surface to redistribute pressure about a surface of a patient. The magnetorheological material may include a distribution of ferromagnetic particles disposed within a polymeric material and exhibits a shape conforming, variable stiffness in response to exposure to a magnetic field. A controller may be provided and configured to create a correlation of patient specific data with an optimal stiffness or inflection force deflection (IFD) of the patient support surface, and generate a strength of the magnetic field based on the correlation.

The present disclosure includes a wheelchair configured to reposition an occupant between a lowered and a raised position. The wheelchair can include a frame, a seat moveable relative to the frame, a drive wheel, one or more pairs of arm assemblies, and one or more sensors. The arm assembly includes a wheel configured to move from a first spatial location when the wheelchair is operating on flat, level ground to a second spatial location that is different than the first spatial location. Arm limiters can selectively engage the arm assembly based on at least one of a seat position, position of the arm assembly, and surface conditions of ground surface. The arm limiters can limit the range of motion of the arm assembly and sometimes other operational aspects of the chair.

A system for safely containing an infant on a mattress is described. The system includes a plurality of panels that extend upwardly from a base that supports the mattress, wherein the plurality of panels and the base form an enclosure around the mattress, and wherein at least one of the plurality of panels is configured to have a locked position and an unlocked position. The system also includes a detection system that detects when the at least one of the plurality of panels is in the unlocked position and a lighting system operatively coupled to the detection system, wherein the lighting system is configured to emit light when the at least one of the plurality of panels is detected to be in the unlocked position. Furthermore, the system includes a power system that provides energy to the lighting system for emitting the light.
