MUMBAI, India, June 24 -- Intellectual Property India has published a patent application (202647067641 A) filed by Spindrift Innovations, LLC on May 29, 2026, for Differential Dual Sensor Contactless Magnetic-Mode Electrical Current Sensors With Tamper Detection.
Inventors include Zucker, Robert, D.; and Weber, Robert, P..
The application for the patent was published on June 12, 2026, under issue no. 24/2026.
Abstract: A dual differential contactless current sensor uses a pair of magnetic sensors placed adjacent to a conductor, such as a metallic trace on a printed circuit board, which is conducting electrical current. The ability to detect and measure a tampering magnetic field in such a sensor is provided by a circuit that sums the outputs of the pair of magnetic sensors. The circuit can output an alarm signal, such as a programmable one-bit alarm that indicates when the external magnetic field exceeds a programmed threshold, or an analog voltage proportional to the external field. The alarm signal can be polled by additional circuitry that indicates to the stakeholders that a party is attempting to alter the power measurement.
