PULSED ULTRA-WIDEBAND SENSOR AND THE METHOD THEREOF

摘要

A pulsed ultra-wideband sensor comprises a control unit designed for forming a time delay of a synchronizing pulse, a probing signal forming path, a transmitting antenna, a receiving antenna, a path of a probing signal transmitter, with an output of said path being connected to the transmitting antenna, a path of a return signal receiver, with an input of the path being connected to the receiving antenna, and a first electronic switch. The input of the first electronic switch is connected to the output of the path for forming a probing signal, and its outputs—to the input of the path of the probing signal transmitter and to the path of a return signal receiver. The outputs of the channels for processing a return signal, which are parts of the path of the return signal receiver, are connected to the path for calculating a respiratory rate and a heart rate.

主权项

1. A pulsed ultra-wideband sensor, comprising:
an antenna configured to receive a return signal; a first receiving means for generating a first signal in response to the return signal, the first signal including information on a first physiological parameter and a second physiological parameter; a second receiving means for generating a second signal in response to the return signal, the second signal including information on the first physiological parameter and the second physiological parameter, the first signal and the second signal being in quadrature; a first detecting means for detecting the first physiological parameter in response to the first signal from the first receiving means and the second signal from the second receiving means; and a second detecting means for detecting the second physiological parameter in response to the first signal from the first receiving means and the second signal from the second receiving means.
