Abstract: 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 a first switch of the at least two switches, and to change from the locked state to the unlocked state when a user operates a second switches of the at least two switches for a predefined time period.

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.

Abstract: A total body relaxation system comprising a plurality of vibrating elements and a control circuit connected to the vibrating elements to provide an electrical stimulus to energize the vibrating elements, the control circuit including a stress sensing circuit for sensing relative total body stress and a display element for providing a visual indication of total body stress.

Abstract: 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.

Abstract: A vibrator is disclosed for mounting on furniture in which a pair of vibrator motors is each mounted to an independent, long, relatively rigid resonator member capable of transmitting vibrations, the two long resonators for the respective motors being parallel to one another and mounted by non-rigid means such as a sheet of cardboard or springs to the remainder of the structure of the furniture. One form of complete unit comprises a non-rigid sheet containing two rigid rods each associated with an off-center vibrating motor, which underlies the surface of the furniture contacted by the user. A vibrator controller supplies the two vibrator motors with 60 Hertz pulsed DC current which is amplitude modulated at approximately 16 cycles per minute, with the modulation supplied to one motor 180.degree. out of phase with the other motor so that the user experiences the sensation of a moving wave.
