    Abstract: A system for detecting vehicle body damage is disclosed. One or more ultrasonic transceivers are installed on a portion of the vehicle body and configured to transmit and receive ultrasonic sound waves. One or more controllers are coupled to the one or more ultrasonic transceivers. The one or more controllers are programmed to cause the ultrasonic transceiver to emit first ultrasonic sound waves and receive first reflected ultrasonic sound waves, store in memory first sound signature data relating to the first reflected ultrasonic sound waves, cause the ultrasonic transceiver to emit second ultrasonic sound waves and receive second ultrasonic sound waves, and determine a presence of damage on the portion of the vehicle body based on second sound signature data relating to the second reflected ultrasonic sound waves deviating from the first sound signature data.

    Abstract: Techniques for satellite signal authentication. In an example, a Global Positioning System (GPS) or global navigation satellite system (GNSS) includes antenna electronics, a processor, and a GPS or GNSS receiver. The antenna electronics is configured to provide, to the GPS or GNSS receiver, signals, wherein the signals comprise GPS or GNSS satellite signals received from a set of GPS or GNSS satellites and/or one or more falsified signals, such as spoofer signals (falsified). The processor is configured to determine, based on an expected location of a respective GPS or GNSS satellite of the set of GPS or GNSS satellites, an expected gain or expected power for a respective signal of the signals. The GPS or GNSS receiver is configured to measure a power of the respective signal, compare the measured power to the expected gain or expected power, and determine whether the respective signal is falsified based on the comparison.

    Abstract: Systems and methods for performing the dynamic anomaly localization of utility pole aerial/suspended/supported wires/cables by distributed fiber optic sensing. In sharp contrast to the prior art, our inventive systems and methods according to aspects of the present disclosure advantageously identify a “location region” on a utility pole supporting an affected wire/cable, thereby permitting the identification and reporting of service personnel that are uniquely responsible for responding to such anomalous condition(s).

    Abstract: An apparatus obtains instances of crowd-sourced data corresponding to a first time period and determines a respective corroboration score based on map data a respective instance of crowd-sourced data. The apparatus determines a first representative corroboration score for the first time period based on respective corroboration scores determined for the instances of crowd-sourced data corresponding to the first time period; and compares the first representative corroboration score for the first time period to a second representative corroboration score corresponding to a second time period, wherein the first time period is different from the second time period. Based on a result of comparing the first and second representative corroboration scores, the apparatus determines whether the instances of crowd-sourced data are potentially manipulated. Responsive to determining that the instances of crowd-sourced data are potentially manipulated, the apparatus performs at least one mitigating action.
