Abstract: A flush-mounted HF (2 to 30 megahertz) transmitting and receiving antenna is developed which is especially suitable for installation on a Jeep (CJ7) type vehicle. This antenna is formed by bonding a copper strip to the inside surface of the non-metallic top of the vehicle. The strip is grounded to the vehicle body just aft of the driver's door and runs overhead to the aft right lower corner of the non-metallic vehicle top which becomes the feed point for the antenna. The strip is connected in two places to an isolated aluminum skin bonded to the top of the vehicle. The antenna is suitable for use as a transmitting antenna provided an impedance matching device (coupler) is inserted between the antenna and the transmitter/receiver.

Abstract: A method for measuring such physiological parameters as pulse rate and respiration without physically connecting electrodes or other sensors to the body. A beam of phased energy, for example microwaves, is directed toward the body of a person at a region thereon which undergoes physical displacement corresponding to variations in the parameter being measured. The phase relationship of the energy reflected from the body is compared with that of the transmitted energy to determine the extent of physical movement of the body region as affected by the parameter being measured. The present method may be used as an overt or covert lie detection technique.
