Proportional actuator control of apparatus

摘要: Apparatus, such as a wheelchair ( 10 ) is proportionally controlled by output signals produced an X-Y input device 26, 58, 90, 100, 110, 360, or 370 ), which may be attached to head 90 hand 112 some other body component, and actuated tilting. The are conditioned prior application the ). Apparatus for conditioning includes transistor sensitivity control 180, 382 A, B), transducer adjustment 344 384 B, 436 signal limiting 226, 394, 396 438 null offset device, null-width generator 418, 130 A/#?, 150 A/#?), rate-of-change controller 144 turn conditioner, steering 160, 170, 398, 400, 416 434 nonlinear 420 that functions control, nonlinearity 422 adjustment, microprocessor 432 used perform some, all, of aforesaid functions.
