Abstract:
A relative positioning system and method has an adjoining pair of spaced apart receivers positioned proximal to an object causing a signal interference with a radio frequency signal detectable by each receiver of the adjoining pair. The radio frequency signal is associated with an emitter. Control electronics operatively couple the spaced apart receivers. The control electronics are configured to determine a direction of the emitter based on the signal interference. In an embodiment of the system and method the emitter is associated with an object of interest, the signal encodes information relating to the identity and status of the object, and information and heading of the object are cutaneously communicated to an operator by an article worn by the operator.

US Classification:
600407
Abstract:
A method of evaluating or monitoring the medical state of a human subject on the subject includes the steps of: positioning an antenna side of a self-contained radio apparatus for non-invasive, thoracic radio interrogation of a human subject proximally to the heart of the human subject; providing a radio frequency interrogation interference signal from the human subject, the radio frequency interrogation interference signal being low frequency components of reflections of a radio interrogation signal transmitted into the thorax of the subject; and determining with the apparatus on the subject at least at least one stroke volume value of the subject from radio frequency interrogation interference signal generated by the apparatus.
