  • Publication number: 20220052920
    Abstract: A network switch and a network switch system thereof are provided. The network switch includes a plurality of connection ports and a processing circuit. When any of the connection ports receives a first abnormal message packet and one of the connection ports is in a disabled state, the processing circuit sets the connection port in the disabled state to switch to an enabled state, and the processing circuit does not forward the first abnormal message packet in the single loop network. When one of the connection ports is abnormal and each of the connection ports forming the single loop network is in the enabled state, the processing circuit sets the abnormal connection port to switch to the disabled state, and transmits a second abnormal message packet to other network switches in the single loop network through another connection port that is not abnormal.

  • Publication number: 20210356577
    Abstract: A phased-array Doppler radar includes a two-way splitter, a transmit antenna, a receive antenna array, an ILO, a demodulation unit and a digital signal processing unit. A reference signal is split by the two-way splitter to the transmit antenna for transmission to targets and the ILO for injection locking. Signals reflected by the targets are received by the receive antenna array as received signals. An injection-locked signal generated by the ILO and the received signals received by the receive antenna array are delivered to the demodulation unit. The received signals are demodulated into baseband I/Q signals by the demodulation unit that uses the injection-locked signal as a local oscillator signal. The baseband I/Q signals are processed by the digital signal processing unit to obtain a digital beamforming pattern.
