    摘要： A powered movable chair controllable by a user. The chair includes a frame, a powered apparatus mounted to the frame to power the movable chair, and a controller including a control circuit coupled to the powered apparatus. The control circuit includes at least two switches for selectively controlling a change of the status of the powered apparatus between a locked state and an unlocked state. The control circuit is operable to generate an output signal allowing control of the powered apparatus in the unlocked state and preventing control of the powered apparatus in the locked state. The control circuit is further operable to change from the unlocked state to the locked state when a user operates only a first switch of the at least two switches, and to change from the locked state to the unlocked state when a user operates two switches of the at least two switches.

    摘要： A vibration producing system for use in vibratory furniture and including first and second vibrator motors for producing vibrations upon being energized, a full wave rectifier having input terminals connected to the power supply and a pair of output terminals for providing full wave rectified current. A first switch has a first mode for connecting the first vibrator motor to the output terminals, a second mode for connecting the vibrator motor to the rectifying means so that the first vibrating means receives alternate half waves of the alternating current having a first polarity and a third mode for open circuiting the first vibrator motor. A second switch has a first mode for connecting the second vibrator motor to the output terminals, a second mode for connecting the second vibrator motor to the rectifying means so that the second vibrator motor receives alternate half waves of the alternating current having a second polarity, and a third mode for open circuiting the second vibrator motor.
