Thermal excitation of sensory resonances
First Claim
1. Apparatus for exciting in a subject a sensory resonance, the sensory resonance having a resonance frequency, the apparatus comprising:
- generator means for generating voltage pulses with a pulse frequency in the range 0.1 to 45 Hz;
heat inducing means, connected to the generator means, for inducing in the skin of the subject heat pulses with an intensity less than 10 mW/cm2, and a frequency equal to the pulse frequency; and
tuner means for tuning the pulse frequency to the resonance frequency.

Abstract
In man, autonomic and cortical resonances of the nervous system can be excited by inducing subliminal heat pulses in the skin by means of a resistive heat patch, laser, heat lamp, or microwave radiation, or through a slow air jet that carries a small periodic fluctuation in temperature. Deeply subliminal skin temperature oscillations of frequency near 1/2 Hz induced in a subject by any of these means cause sleepiness, drowziness, relaxation, a tonic smile, ptosis of the eyelids, a tense feeling, sudden loose stool, or sexual excitement, depending on the precise pulse frequency used. For certain higher frequencies, the induced subliminal skin temperature oscillations cause fractured thought and a slowing of certain cortical processes. The method and apparatus can be used by the general public as an aid to relaxation, sleep, or arousal, and clinically for the control and perhaps treatment of tremors, seizures, and emotional disorders. There is further application in the form of nonlethal weapons, involving a pulsed infrared laser or a pulsed microwave beam, tuned to a sensory resonance pulse frequency.
