    摘要: A programmable automatic positioning chair for medical application. The chair has moveable support surfaces which are driven by electric motors to preprogrammed positions. Motor speed is determined by measuring the motor current, and the motor speed is integrated by a microprocessor to produce a computed value of surface position. The chair operates "open loop" without any feedback from position sensors.
