Abstract: Described embodiments include an apparatus that includes a flexible electrically-insulating substrate, including an inner surface and an outer surface, and shaped to define (i) multiple narrower channels passing between the inner surface and the outer surface, and (ii) one or more wider channels passing between the inner surface and the outer surface. The apparatus further includes an outer layer of an electrically-conducting metal covering at least part of the outer surface, an inner layer of the electrically-conducting metal covering at least part of the inner surface, a plating layer of the electrically-conducting metal that plates the wider channels such as to connect the outer layer to the inner layer, and respective columns of the electrically-conducting metal that fill the narrower channels such as to connect the outer layer to the inner layer. Other embodiments are also described.

Abstract: A biomedical apparatus for monitoring and evaluating physical properties associated with a biologic or biomedical system is provided. When adapted to monitor and evaluate pressure at any interface between two abutting surfaces, the biomedical apparatus includes a sensor pad including at least one pressure sensor that is adapted to be disposed between the two surfaces to measure pressures exerted on one surface by the other surface, and generate data representative of measured pressures. At least one transducer is provided, with one transducer being in communication with each sensor for generating output signals representative of pressures measured by the sensor. Electronic circuitry further is provided that includes data processing circuitry for processing output signals generated by the transducer and generating pressure data based upon pressures measured by the sensor.

Abstract: A modular backrest system for a wheelchair is removably attached to backrest posts of the wheelchair. The backrest system includes a back support that provides a surface against which the back of a wheelchair user rests, and a support chassis mounted to the back support for supporting the back support at a desired incline with respect to the posts, and at a desired seat depth with respect to the seat. An attachment assembly is further included that is operably connected to the support chassis at two locations and to the posts to allow the support chassis and back support to be readily removed from or attached to the chair. The particular back support employed in conjunction with the support chassis is based upon the support needs of the wheelchair user. One embodiment of the back support includes a backing plate, and a cushion or insert attached to a forwardly presented face of the backing plate against which the back of the individual rests when sitting on the seat.

Abstract: A contoured backrest for a wheelchair may be moved to and retained in different positions and thus accommodates individuals of varying size and disabilities. The backrest carries clamps to which outriggers are fitted, and these outriggers extend transversely across the back face of the backrest. The outriggers are laterally adjustable to accommodate wheelchairs of different widths. They have offset ends beyond the sides of the backrest, and these ends fit into brackets on back posts that are part of the wheelchair. When the clamps are released, the outriggers may be rotated. This enables the position of the backrest to be adjusted forwardly and backwardly, upwardly and downwardly, and angularly.
