Patent number: 11936175Abstract: A reverse power connection preventing circuit includes a diode and an actuation unit that are connected in series between a positive input terminal and a negative input terminal of a circuit breaker. A positive electrode of the diode points to the negative input terminal of the circuit breaker, and a negative electrode of the diode points to the positive input terminal of the circuit breaker. When a power supply is forward connected to the circuit breaker, the diode is cut off, there is no current on the actuation unit, and the reverse power connection preventing circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode conducts, and the actuation unit is configured to prevent closing of the circuit breaker, and/or the actuation unit is configured to perform an alarm prompt, to perform an early warning.Type: GrantFiled: July 15, 2022Date of Patent: March 19, 2024Assignee: Huawei Digital Power Technologies Co., Ltd.Inventors: Zezhou Yang, Xiaoke Ran, Wanxiang Ye, Liqiong Yi

Patent number: 10921356Abstract: This disclosure relates to optical RF spectrum analysers and methods for analysing an input RF signal. An optical modulator modulates an input RF signal onto a carrier frequency and an optical spectral weight with a spectral weight function modifies the modulated optical signal. The spectral weight defines a frequency relationship between the spectral weight function and the carrier frequency. A frequency control module modifies the frequency relationship between the spectral weight function and the carrier frequency over time. An optical sensor senses the modified optical signal over time and to generates an RF signal over time. A signal recovery module calculates the RF spectrum based on the RF signal over time. Shifting the spectral weight against the carrier frequency over time results in a high spectral resolution even if the spectral weight is relatively broad band. The result is an increased spectral resolution at a reduced price/complexity and increased robustness.Type: GrantFiled: August 22, 2017Date of Patent: February 16, 2021Assignee: The University of SydneyInventors: Shijie Song, Xiaoke Yi
