Abstract: The present disclosure provides an improved Rogowski-type current sensor. The current measurement coil, and the compensation coil are provided on the same board. The measurement coil and the compensation coil are arranged such that they at least partially overlap by virtue of each repeatedly changing side of the board. This arrangement makes the current sensor far better at rejecting interference than certain other PCB Rogowski type coil arrangements.

Abstract: An apparatus, system, and method for wireless communication with remote devices that reduce or eliminate interference from zero-mean noise and deterministic signals within the operating system frequency band are provided. An interrogator uses dithering of the initiation time of sequential transmitted signals or sets of transmitted signals with synchronous accumulation of the resulting received signals to reduce the relative strength of interfering signals while increasing the relative strength of the desired signal. The apparatus, system, and method are particularly advantageous when used to extract identification and/or sensor data from passive wireless sensors and tags.
