Patent ID: 6966083

Claim:
A magnetic levitation bed comprising; a bed frame, said bed frame comprising a plurality of permanent magnet arrays arranged at a bottom side thereof, a first cam-fitting mechanism, and a second cam-fitting mechanism; and a base adapted to support said bed frame, said base comprising a power control box, a plurality of electromagnet arrays arranged corresponding to said permanent magnet arrays at said bed frame and controllable by said control box to attract and repulse said permanent magnet arrays, a first low-speed motor controllable by said power control box, a first cam coupled to said first low-speed motor corresponding to said first cam-fitting mechanism for acting against said first cam-fitting mechanism to oscillate said bed frame in transverse direction upon rotation of said first low-speed motor, a second low-speed motor controllable by said power control box, a second cam coupled to said second low-speed motor corresponding to said second cam-fitting mechanism for acting against said second cam-fitting mechanism to oscillate said bed frame in longitudinal direction upon rotation of said second low-speed motor, a remote-control receiver controllable by a remote controller for controlling the operation of said power control box, and sensor means adapted to detect oscillation of said bed frame and to provide a signal indicative of the position change of said bed frame to a microprocessor in said remote-control receiver for enabling said remote-control receiver to control the operation of said power control box subject to the data received from said sensor means.
