  • Patent number: 10816656
    Abstract: In a vital sign sensor of the present invention, an antenna assembly radiates an oscillation signal generated by a SIL oscillator to an object in a form of a wireless signal and receives a reflected signal from the object, and the reflected signal can have the SIL oscillator injection-locked. The wireless signal radiated from the antenna assembly is transmitted to a demodulator for demodulation such that the vital signs of the object can be obtained. Additionally, an isolator of the antenna assembly is provided to prevent the SIL oscillator from receiving a clutter reflected from the demodulator and an environment where the demodulator is placed. As a result, the clutter can't influence the vital sign detection of the object.

  • Patent number: 10413210
    Abstract: A non-contact vital sign monitoring system transmits wireless signals to the same side of a biological subject via two antennas with different gains, and the two antennas receive two reflected signals from the biological subject with random body movement. Under a proper setup of the two antennas, the two reflected signals can be adjusted by an amplitude and phase adjusting unit to have the Doppler shift components caused by body movement with equal magnitude and out of phase and the Doppler shift components caused by vital signs with different magnitude. Therefore, the random body movement effect can be cancelled based on the relation between the two reflected signals in using the system to monitor the vital signs of the subject.
