Abstract: A shielded antenna (100) includes a spiral antenna (110) and a shield (120) disposed on the spiral antenna. The spiral antenna comprises a plurality of substantially concentric loops. The shield comprises a plurality of electrically isolated electrically conductive segments forming a regular pattern, such that in a top plan view, at least one segment overlaps a portion of at least two loops, and at least one pair of adjacent conductive segments defines an electrically insulative gap therebetween.

Abstract: Systems and methods for sensing, measuring, or monitoring the temperature of an electrical transmission line of an electrical cable, are provided. A temperature sensitive inductor is disposed in thermal contact with the electrical transmission line. The temperature of the electrical transmission line can be sensed, measured, or monitored by measuring the inductance of the temperature sensitive inductor. Mechanisms and methods to eliminate, minimize, or account for the magnetic coupling between the current carried by the electrical transmission line and the temperature sensitive inductor are provided.

Abstract: Systems and methods for generating random bits by using physical variations present in material samples are provided. Initial random bit streams are derived from measured material properties for the material samples. In some cases, secondary random bit streams are generated by applying a randomness extraction algorithm to the derived initial random bit streams.

Abstract: At least some aspects of the present disclosure feature a radio frequency identification (RFID) tag adapted to wirelessly communicate with a remote transceiver. The RFID tag includes a substrate; and first and second circuits disposed on the substrate and comprising respective first and second antennas magnetically coupled to one another. At least some aspects of the present disclosure feature a RFID tag having a plurality of RF circuits, where each RF circuit is electronically coupled to a sensing element.

Abstract: A sensing element includes a substrate including an electrically non-conductive surface, at least one high surface energy region, and an electrode pair structure disposed on the electrically non-conductive surface. The electrode pair structure includes at least one pair of electrodes having a gap therebetween. At least one of the electrodes is at least partially within the at least one high surface energy region. The sensing element is configured to sense fluid-soluble particulate matter.
