Abstract:
A person support apparatus includes one or more motorized actuators that are braked in different manners depending upon whether or not electrical power is available to the control system. When electrical power is not available, a delay circuit delays closing a first switch that, when closed, short circuits the terminals of one of the motors. When power is available, other switches are opened and closed in a manner that short circuits the terminals of the motor while the first switch remains open. The other switches may be part of an H-bridge. The control system may also detect back emf (electromotive force) generated by the motor when electrical power is available and issue a notification to a technician or other user if an amplitude and/or duration of the detected back emf exceeds a threshold.

Claim (Index 12):
A person support apparatus comprising:\n a base having a plurality of wheels; a support surface adapted to support a person thereon, the support surface comprising a backrest and a seat; an actuator having a motor adapted to pivot the backrest with respect to the seat; a sensor adapted to detect movement of the backrest when the motor is driven; a voltage sensor adapted to detect a voltage across terminals of the motor when the motor is braked; and a control system adapted to keep track of a position of the backrest using outputs from both the sensor and the voltage sensor, the control system using the outputs from the sensor to keep track of the position of the backrest when the motor is being driven and the control system using the outputs from the voltage sensor to keep track of the position of the backrest when the motor is being braked.
