Abstract:
1. The method of evaluating a temperature related physical parameter at a subcutaneous region of an animal body, comprising the steps of: (a) providing one or more passive resonant implants having an electromagnetic response to an extra body applied excitation electromagnetic field, said response exhibiting a predetermined resonant center frequency or frequencies when said implant is at a monitor temperature or temperatures; (b) providing a detector assembly with an antenna, said detector having a detector output of given amplitude in response to antenna detections of said electromagnetic response at said predetermined resonant center frequency; (c) positioning said detector assembly antenna at an extra body location effective for deriving said detector response; (d) positioning said one or more implants in thermal transfer relationship with said animal body region; (e) applying said excitation electromagnetic field from an extra body location for an excitation interval effective to elicit said electromagnetic response; (f) determining the presence of said monitor temperature or temperatures within a resonance time subsequent to said excitation interval in correspondence with said detector output; and (g) evaluating said physical parameter in correspondence with said step (f).
