    Abstract: In the examples provided herein, an apparatus has a memristive element coupled to a pin of an integrated circuit, wherein the memristive element switches from a first resistance within a first range of resistance values to a second resistance within a second range of resistance values in response to an electrostatic discharge (ESD) event at the pin. The apparatus also has read circuitry coupled to the memristive element to determine whether a resistance of the memristive element is in the first or second range of resistance values, wherein the read circuitry includes a first transistor. Further, the coupling between the read circuitry and the memristive element does not include a direct path for current from the ESD event to a gate terminal of the first transistor.

    Abstract: A low fault current isolation arrangement senses loss of voltage and automatically isolates and de-energizes a down live primary wire if overcurrent protection devices have not cleared the high impedance fault in an electric power distribution network. Incorporating an operator selectable time delay response, the low fault current isolation arrangement permits overcurrent protection devices to attempt to detect and shut down the affected conductor, and isolates and shuts down the low current fault if the overcurrent devices are not successful. The isolation arrangement continuously monitors AC voltage as remotely provided by smart meters even after a fault location is de-energized, and serves as a back up, and not as a replacement, for existing overcurrent protection schemes. A host computer operates in conjunction with plural smart meters each coupled to an associated customer distribution transformer in conjunction with the fault isolator to detect and shut down high impedance faults.

    Abstract: The present application discloses detecting manipulation of GNSS signals using a second time source. If two or more GNSS constellation signals are being detected, the phase error between the GNSS constellation signals may be monitored. When the phase error drifts, then manipulation is determined. The integrity of a GNSS constellation signal may be monitored using an internal time source such as a crystal oscillator by monitoring a slope of the free running counter at the detected rising edges of a pulse-per-second signal from the GNSS constellation. If more than two GNSS constellations are monitored, a voting scheme may be used to determine the manipulated GNSS constellation.
