摘要： A temporary power delivery system includes a power source, a booth stringer, and a portable GFCI device. The GFCI device is receives current from the power source by a first terminal and delivers current to the booth stringer by a second terminal. An electronic processor of the GFCI device compares a combined magnitude of current flowing through first and second phase conductors of the GFCI device to a magnitude of current flowing through a neutral conductor of the GFCI. The electronic processor also compares a first voltage between the first phase conductor and neutral conductor to a second voltage between the second phase conductor and neutral conductor. A circuit breaker of the GFCI device is opened if a difference between the combined magnitude of phase conductor current and neutral conductor current exceeds a first threshold or a difference between the first voltage and second voltage exceeds a second threshold.

摘要： A method and system for suppressing EMP-induced voltage surges due to detonation of a nuclear weapon at high altitude generating an EMP (HEMP) comprising E1, E2, and E3 component pulses. Surge protection assemblies are positioned intermediate a signal stream and a plurality of electronic device ports associated with a plurality of communication channels of networked devices. Single-channel multimode surge suppressing systems are combined to form multi-port multimode protection systems that connect directly to multiport networked devices supporting communication channels with mixed signals data and direct current power in Gigabit Ethernet networks supporting PoE. The surge suppressing systems mitigate differential and common mode induced interference and protect from overvoltage surges associated with E1, E2, and E3 components of the HEMP and mitigate the over-voltages to predetermined allowable levels within the predetermined time. The surge suppressing systems is interoperable with multimode PoE and support endpoint and midspan PoE devices of Gigabit networks.

摘要： A personal electronic device can include a main printed circuit board having disposed thereon a processing unit, one or more auxiliary circuits coupled to the main printed circuit board by one or more corresponding flexible printed circuits and one or more temperature sensors disposed on one of the flexible printed circuits. A processing unit of the portable electronic device can be configured to monitor the one or more temperature sensors, provide a warning in response to a monitored temperature exceeding a first threshold, and to cause a shutdown of at least a portion of the personal electronic device in response to the monitored temperature exceeding a second threshold. The temperature sensors can be negative temperature coefficient resistors.

摘要： Conventional GFCI-type technology typically relies solely on onsite control—for example, pushing a reset button physically located at the impacted circuit to clear a trip and resume operation. For simpler/lower voltage systems—such as outlets in a residence—this is not particularly labor-intensive or confusing. However, for large, complex, and/or high voltage systems—such as sports lighting systems with multiple circuits dozens of feet apart in locked enclosures—trying to perform the same task of pushing a reset button and clearing a trip is much more labor-intensive, and confusing not only in locating the impacted circuit, but in determining what happens next if pushing the reset button does not resume operation. Presented herein are remote control options for GFCIs which could be used in addition to, and not instead of, conventional GFCI-type functionality—or could provide remote-only reset function where a system has no onsite reset button.
