Claim:
An apparatus comprising: a receiver of multisensory input from a plurality of input devices; a command-extractor that is operable to extract from the multisensory input a command that is associated with a patient-movement-actuator, the command-extractor being operably coupled to the receiver of the multisensory input; a lift-device-controller that is operable to receive the command from the command-extractor and that is operable to generate at least one electrical signal from the command, the lift-device-controller being electrically coupled to the command-extractor; and a two dimensional patient-lifting-device that is electrically coupled to the lift-device-controller, the two dimensional patient-lifting-device having two-dimensional motion in four directions, the patient-movement-actuator including a double-pole-double-throw relay for each direction of motion, the patient-movement-actuator having four double-pole-double-throw relays.
