摘要： Devices and methods for detection of active return loss for an antenna element of a plurality of antenna elements of a phased array antenna are provided. An exemplary device can convert a voltage differential at an input of a power amplifier (PA) to first current. The device can convert a coupled voltage corresponding to a signal transmitted from the PA to a respective antenna element, to a second current. The device can convert a reflected voltage corresponding to a signal reflected from the respective antenna element, to a third current. The device can convert the first current, the second current, and the third current to an output voltage at a generator output. The device can further have a controller that can adaptively generate codebooks for transmission based on the output voltage.

摘要： Electrical current and/or voltage monitoring powered by induction and/or conductive spike, and related devices, apparatuses, systems, and methods are disclosed. An electricity monitoring device can include a measuring conductor electrically coupled to a monitored energy source to detect/read voltage of the monitored energy source. The electricity monitoring device can include an electrical component in which a fluctuating magnetic field is induced from a fluctuating flow of electrical current in the monitored energy source, the fluctuating magnetic field to produce an electromotive force to provide electrical energy. The electricity monitoring device can include a controller that can further include processing circuitry to be powered by the provided electrical energy, the controller coupled to the measuring conductor to determine a present run-time electrical voltage of the monitored energy source based on a reading of the measuring conductor. In some embodiments, the electrical component can be a Rogowski coil.

摘要： One or more implementations of the present disclosure are directed to sensor probes of measurement systems for measuring a plurality of electrical parameters, (e.g., voltage, current) of a conductor and methods for measuring same. In at least one implementation, the sensor probe integrates a Rogowski coil and a non-contact voltage sensor that are arranged relative to each other such that when positioned to measure a conductor, such as a wire, the Rogowski coil and the non-contact voltage sensor are held in proper position for measurement.

摘要： An AC/DC leakage detection method, which supports the detection of DC leakage and AC leakage. A DC leakage current and a low-frequency leakage current are measured by means of magnetic modulation technology, an AC signal is measured in the form of pure induction, and two detection modes are performed in a time-sharing manner. A collected leakage signal is converted into a digital signal through an AD converter. By means of the method of the present invention, the processing of a leakage signal is divided into three channels for respectively processing DC leakage, low-frequency AC leakage, and high-frequency AC leakage. The overall effective value of residual current is calculated by integrating results of DC detection and AC detection. The method of the present invention supports the detection of a suddenly increased current; and when there is a suddenly increased current, detection mode switching is performed by detecting the current sudden change of the current.

摘要： One example includes a flux switch system. The system includes an input stage configured to provide an interrogation pulse. The system also includes a plurality of flux loops configured to receive an input current. Each of the flux loops includes a Josephson junction configured to trigger to generate an output pulse in response to a first polarity of the input current and to not trigger to generate no output pulse in response to a second polarity of the input current opposite the first polarity. The system further includes an output stage configured to propagate the output pulse to an output of the flux switch system.
