Patent ID: 7181793

Claim:
A brain-wave adjustable bed, comprising: a) a bed having an upper surface, a lower surface, a head end, a foot end and sides between the head end and the foot end; b) an ankles fixing device mounted adjacent the foot end of the bed; c) a bottom frame for supporting the bed, the bed being rotatably mounted to the bottom frame by a central hinge, so that the bed may rotate within predetermined angles around the central hinge; d) a brain waves detection means comprising: i) a head set for a user lying on the bed to put on; ii) a control section having an input coupled to the head set and an output displayed on a control panel; the output producing a signal representing brain waves of the user wearing the head set, the brain waves comprising at least alpha waves and beta waves; iii) a frequency analyzer for separating alpha wave and beta wave components in the brain waves, comprising an input coupled to the output of the control section of the brain waves detector, a filter for separating at least the alpha waves from the signal on the output of the control section based upon a frequency range and an output comprising at least an alpha signal proportional to an amplitude of alpha waves in the brain waves; and e) means for adjusting the inclination of the bed, coupled to the bed and the frame, having a control input coupled to the output of the frequency analyzer of the brain waves detection means and a mechanical output which rotates the bed in response to a signal on the control input, so that the bed is rotated to a predetermined selected angle based upon the amplitude of at least the alpha signal.
