ABSTRACT:
An articulated bed wherein all power signals within the mattress or supporting frame are maintained at 24 volt DC or less. Both body supporting surface manipulating motors and vibratory motors are accommodated. Remote control of all motors is provided, with control signals being processed as a function of a key in order to minimize the likelihood of instructions for one bed being intercepted and acted upon by another bed within range of the remote control device. A plurality of discrete vibration levels are accommodated through use of pulse width modulation control signals. Overload operation of the lifting motors is sensed, and the motors are immediately shut down regardless of whether contrary instructions are currently prevailing or being received.
