Abstract

In the non-invasive measuring system, a wireless communication device or other sensing device, gathers Doppler information from signals transmitted by the wireless communication or sensing device and reflected off of a target subject. The gathered information is transferred, preferably, over the existing communication network infra-structure to a presentation device. By placing a body sensor on the target subject, the return of the signal reflected from the subject is enhanced and/or additional information is modulated onto the return signal.
