  • Patent number: 10859604
    Abstract: A sensor for inductively measuring the current in a conductor flowing through a recess in a printed circuit board. Wire loops on the printed circuit board function as the inductive current sensor. Combined with a voltage measurement, the energy being dissipated in the conductor's load circuit can be determined and transmitted wirelessly. Control circuits can be integrated with the metering hardware to enable the remote modulation of the load's power. The inductive sensor(s) can be used to track differences between the load's supply and return currents. If a fault is detected, the circuit can be broken for safety, serving a ground fault circuit interruption (GFCI) purpose. The claimed invention can report measurements in real time, providing time series data for analyses sufficient to detect or identify an anomaly in the function and operation within a system's load or electrical power distribution network.

  • Patent number: 10845394
    Abstract: Within electrical test equipment systems comparator bridges are employed to provide the required dynamic range, accuracy, and flexibility. However, whilst bridge based measurement configurations remove many of the issues associated with making measurements at accuracies of sub-parts, a part, or few parts per million they still require, in many instances, that a null point be determined where the bridge is balanced. However, this becomes increasingly difficult within electrically noisy environments, with modern digital multimeters, and where the desired measurement point within the electrical system is physically difficult to access particularly when improved accuracy in calibration, standards, and measurements on circuits and components means measurement systems must operate at 50 parts per billion (ppb) and below.
