Abstract
A vital-sign detecting system includes radio-frequency (RF) tags disposed on detected subjects respectively, the RF tags respectively generating incident RF signals with different predetermined frequencies, and the incident RF signal projecting on a corresponding detected subject to generate a corresponding reflected RF signal; and at least one RF radar that demodulates the reflected RF signal to obtain vital sign of the corresponding detected subject, and identifies the detected subject according to associated frequency of the reflected RF signal.
Claims8
A vital-sign detecting system, comprising:
- a plurality of radio-frequency (RF) tags disposed on detected subjects respectively, the RF tags respectively generating incident RF signals with different predetermined frequencies, and the incident RF signal projecting on a corresponding detected subject to generate a corresponding reflected RF signal;
- and
- at least one RF radar that demodulates the reflected RF signal to obtain vital sign of the corresponding detected subject, and identifies the detected subject according to associated frequency of the reflected RF signal;
- wherein the RF tags generate the incident RF signals independent of the RF radar, and frequencies of the incident RF signals are different.
A vital-sign detecting method, comprising:
- generating an incident RF signal with one of different predetermined frequencies;
- projecting the incident RF signal on a corresponding detected subject to generate a corresponding reflected RF signal;
- demodulating the reflected RF signal to obtain vital sign of the corresponding detected subject;
- and
- identifying the detected subject according to associated frequency of the reflected RF signal;
- wherein the RF tags generate the incident RF signals independent of the RF radar, and frequencies of the incident RF signals are different.
