Abstract: A cordless wireless and mobile display system having an integrated system for delivering uninterrupted power to a display is described. The cordless wireless and mobile display includes wireless capabilities that allows it to receive and transmit information from associated medical devices and to send data to other designated devices. A battery assembly includes a primary and secondary battery that supplies uninterrupted power to a display. Sensors periodically sample the power output from the battery in current use to ensure that enough power is available to the display. When sensors detect power output levels have fallen below a preset value, indicators alert users that the system is switching to a backup power supply and that the primary battery supply needs recharging.

Abstract: A wheelchair composed of a frame with a seating surface, a backrest, a plurality of wheels and a lifting device for lifting a user of the wheelchair from a seated position to a standing position. The lifting device includes two spars connected to the frame to have a substantially vertical orientation when in use and a mechanism for converting a manual force into a lifting force for lifting the user toward the standing position. The mechanism for converting is composed of: a seating band positionable to act on the user's body; at lease two deflection rollers on each spar; and at least one lifting cable linked to the seating band and passing around the deflection rollers in order to guide the seating band in a manner to cause the lifting force to be directed forwardly and upwardly.
