DEVICE OF INPUT OF COORDINATES FOR STATION CONTROL OF COMPUTER BY PEOPLE WITH LIMITED PHYSICAL ABILITIES Russian patent published in 2010 - IPC A61F4/00 G06F3/33 

FIELD: medicine.

SUBSTANCE: invention relates to medicine and can be used for people with paralysis of upper and lower extremities. Device contains electrically connected power unit, coordinate device, which sets coordinates and controls computer cursor, and is made with possibility of its placement in oral cavity, unit of signal processing, transmitter, two functional contact buttons for performing functions of "mouse" buttons, and one button of switching work type. Coordinate device is provided with bendable projection, loop of current-conducting tracks, microcontroller, located in loop and switched in the chain of current-conducting tracks, and electric slot, installed on the end of loop of current-conducting tracks with possibility of its electric connection with unit of signal processing. Coordinate device is made in form of hollow disc with rounded on radius external edge. Internal disc cavity is formed by first and second layer of flexible polymer film, connected on external contour. First layer of hollow disc has shape of semisphere concave into disc cavity. Second layer of hollow disc has flat shape, on whose internal surface applied are current-conducting concentric tracks, grouped into four mutually perpendicular sectors. Current-conducting tracks of adjacent sectors are separated from each other by common current-conducting track, and distance between current-conducting concentric tracks decreases from centre of disc to periphery. On internal surface of concave disc semisphere applied is resistant layer, made in form of radial resistant sections, which are located in form of concentric rings. Each ring is located above corresponding current-conducting concentric tracks, width of concentric rings, as well as length of resistant sections, equals distance between corresponding current-conducting concentric tracks. First and second layers of polymer film are connected with each other in central part of hollow disc with formation of central bridge. Bendable projection and loop of current-conducting tracks are formed by first and second layers of polymer film, connected on their flat surface. Bendable projection and loop are connected with disc edge. Functional contact buttons and button for switching work type are placed in bendable projection.

EFFECT: improvement of performance characteristics.
