  • Publication number: 20200352018
    Abstract: An undulator is adapted to a synchrotron storage ring or free electron lasers (FEL), especially to an undulator capable of switching polarization mode rapidly. In comparison with the EPU (elliptically polarized undulator) of APPLE II (Advanced Planar Polarized Light Emitter II) which conceived by Dr. S. Sasaki, the provided undulator does not use mechanical transmission mechanisms to drive the four magnetic pole arrays composed of permanent magnets. Hence, the polarization mode can be switched rapidly. Moreover, a polarization method of electron beam is also provided.

  • 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.

  • Publication number: 20200322897
    Abstract: In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a transmitting UE. The transmitting UE transmits a reference signal and data to one or more receiving UEs. The transmitting UE receives one or more response signals from the one or more receiving UEs on a particular resource element. Each of the one or more response signals represents at least one of (a) a respective indication based on a measurement at a respective receiving UE, of the one or more receiving UEs, transmitting the each response signal and (b) a respective acknowledgment from the respective receiving UE associated with the data. The transmitting UE determines a transmission power at the transmitting UE based on the respective indications. The transmitting UE transmits data to the one or more receiving UEs at the transmission power.

  • Patent number: 10601132
    Abstract: An active phase switchable array includes a plurality of antenna elements and a bias circuit. Each of the radar elements includes an antenna, a power coupling network and an injection-locked oscillator (ILO), and each of the antenna elements is coupled with each other through the power coupling networks for operating the ILO of each of the antenna elements in self- and mutual-injection-locked states. The antenna elements in self-injection-locked state are utilized to detect the vital signs of subjects, and the antenna elements in mutual-injection-locked state are utilized to produce phase difference between the radiating signals of the antenna elements for forming a beam. As a result, the active phase switchable array can simultaneously detect the vital signs of multiple subjects.
