Abstract: A handheld system radio frequency identification (RFID) system for fine-grained RFID localization of an RFID target. Also disclosed is a mechanism for localizing RFID targets at all orientations through software-controlled polarization of two LP antennas. The system may detect an RFID target using a generated circularly polarized (CP) RF signal and accurately localize the RFID target using a generated linearly polarized (LP) signal. The disclosed systems and techniques discover and localize RFID concurrently and regardless of RFID target orientation.

Abstract: An example system for locating passive RFID tags includes a narrowband RFID reader configured to transmit a narrowband RF signal to energize a passive RFID tag, thereby causing the passive RFID tag to create a backscatter reflection target; a first wideband transceiver configured to transmit a wideband RF signal; a second wideband transceiver configured to: receive the wideband RF signal reflected from the backscatter reflection target; and record time-of-arrival data for the reflected wideband signal; and processing circuitry configured to determine a location measurement of the passive tag based on the time-of-arrival data.

Abstract: A system that uses cooperative arrays of electromagnetic resonating markers in combination with a vehicle mounted resonating transceiver. Markers establish their position placement during a calibration sequence in which cryptographic keys are exchanged, ensuring the markers are placed by authorized personnel and that none can be removed/relocated without detection. Markers can then be reliably polled by passing vehicles to determine relative location in areas of sensor occlusion. The markers can also be securely used for emerging smart city financial transactions such as automated parking, garbage collection, deliveries, tolling or temporary pedestrian markets.

Abstract: A system that includes a radar sensor configured to transmit radar waves receive a first group of reflected radar waves and a second group of reflected radar waves. A restraint includes a material that causes the transmitted radar waves to reflect off the restraint to generate the first group of reflected radar waves, and the second group of radar waves is reflected off objects other than the restraint. A controller is configured to determine a shape of the restraint based on the first group of reflected radar waves.

Abstract: Disclosed herein are systems, methods and/or computer programs for backscatter localization of a tag using access point (AP) mode switching. The apparatus, may comprise means for: receiving distance information associated with at least two APs from a set of at least three APs. The distance information associated with each AP of the at least two APs may be determined based on: dynamically switching the role of said each AP in a different time interval to a transmission mode for transmitting a localization signal to a tag, with the other APs in the set of APs switched to a receiving mode for receiving a backscatter signal from the tag in response to the transmitted localization signal from said each AP. Distance information determined, by the other APs, may be associated with said each AP based on the received backscatter signals corresponding to the transmitted localization signal from said each AP. There may also be provided means for determining a location estimate of the tag based on the received distance information.

Abstract: A system and method for determining the relative position of stations through radio location is proposed. In one aspect, a station is configured as an apparatus having at least one antenna. At least one first station has at least one first antenna, and at least one second station has at least two base-modulated antennas. The first station sends at least one locating signal via the first antenna. The second station reflects the locating signal as a first modulated reflected locating signal via a first base-modulated antenna and as a second modulated reflected locating signal via a second base-modulated antenna. The first station receives the modulated reflected locating signals via the antenna. The phase relationships of the received modulated reflected locating signals are used to ascertain at least one position angle for the relative position between the first station and the second station.

Abstract: An object identification system includes a guided surface waveguide probe that produces a guided surface wave from which object identification tags obtain electrical power to operate, each tag associated with an object; and a plurality of receivers deployed at strategic locations to receive return signals from one or more of the tags as the tags move with the associated objects during a lifecycle of the objects.

Abstract: An object identification system includes a guided surface waveguide probe that produces a guided surface wave that has a frequency-dependent illumination area in which one or more object identification tags are powered by the guided surface wave and outside of which other object identification tags are not powered by the guided surface wave; and a receiver at the illumination area, the receiver receiving return signals from the one or more object identification tags located in the illumination area, the return signals emitted by the object identification tags as an automated response to being powered by the guided surface wave.
