Abstract
A hospital bed has a movably supported part, a selectively actuable drive arrangement for moving the part, a manually actuable control switch, and a control circuit coupled to the switch and drive arrangement. The control circuit includes a microprocessor having an input coupled to the control switch and having an output, and the program executed by the microprocessor selectively actuates the output of the microprocessor based on a function which takes into account the current state of a signal being applied to the microprocessor input. The control circuit also includes a further arrangement which actuates the drive arrangement when the signals from the control switch and microprocessor are both actuated, and which deactuates the drive arrangement when either of these two signals is deactuated.
