Sensible body vibration

Claim 1

A sensible body vibrator, comprising: vibration means including an electromechanical converter mounted in a human body support for generating a plurality of types of mechanical vibrations, each type of vibration being in response to a corresponding input signal, the vibration means being selectively actuated between an operative state and an inoperative state; signal generating means for generating a plurality of input signals for transmission to the vibration means, each signal having a corresponding waveform, and at least one of the plurality of input signals being an emergency input signal with an emergency waveform that the vibration means converts into an emergency vibration; selection means for selecting one of the plurality of input signals from the signal generator means and transmitting the selected input signal to the vibrator means; and control means for actuating the vibrator means to select and transmit a desired one of the plurality of input signals, the control means including an emergency sensor means for sensing a predetermined condition and outputting an output signal in response to detection of the predetermined condition, the control means controlling the selector means to select and transmit to the vibration means the emergency input signal in response to the output signal in preference to the desired one of said plurality of input signals and regardless of the state of the vibration means.
