Abstract

A system for wirelessly monitoring, in real time, certain physiological/biological parameters of an animate body, such as an athlete or a patient. The parameters are sensed and measured by a transducer located on the animate body. The transducer is part of a transponder that includes an electronic unit containing a wireless receiver/transmitter. Remote R/T access units are spaced such that at any given time, signals from the transponder will be received by at least one of the access units where the data can be coupled to a display monitor and the measured parameters viewed in real time. In addition, a real time video image of an animate body, such as a patient/athlete, may be transmitted to a remotely located monitor for monitoring along with the transmitted physiological/biological patient parameters.
