Physics of Sound and Vibration: Effects On Human Electro-Dynamic Physiology

  Bioeffects Research for Emerging RF Technologies M. R. Murphy and J. H. Merritt Radio Frequency Radiation Branch, Human Effectiveness Directorate Air Force Research Laboratory, Brooks AFB, Texas, USA.    Introduction:   New technologies employing radio frequency (RF) emissions are constantly emerging. Some of them employ frequencies and pulse characteristics that have not been well studied for their effects on biological material. Bioeffects research is required to determine the hazard thresholds and interaction mechanisms of such emissions and address the appropriateness of current health and safety standards. Additional data may indicate that current standards are lax and permissible exposure limits (PEL) need to be reduced; or they may indicated that current standards are unnecessarily restrictive and the PEL can be safely raised. This paper concerns recent bioeffects research on two types of emissions: (a) High Peak-Power Low Average-Power Pulses, including Ult...

  Patent No. 3727616   Electronic system for the stimulation of biological systems (Lenskes, Apr 17, 1973) Abstract A receiver totally implanted within a living body is inductively coupled by two associated receiving coils to a physically unattached external transmitter which transmits two signals of different frequencies to the receiver via two associated transmitting coils. One of the signals from the transmitter provides the implanted receiver with precise control or stimulating signals which are demodulated and processed in a signal processor network in the receiver and then used by the body for stimulation of a nerve, for example, while the other signal provides the receiver with a continuous wave power signal which is rectified in the receiver to provide a source of electrical operating power for the receiver circuitry without need for an implanted battery.
