Abstract: An apparatus detects complex time-variant electromagnetic disturbances resulting from a high-altitude nuclear electromagnetic pulse (EMP) or solar storm. The device relies on a circuit (104, 1301) to monitor the input power lines (301, 401, 501) for sustained conducted electrical disturbances associated with the E3 phase of an EMP or solar storm. A separate circuit (105, 1302) monitors the power lines and the ambient environment (503) for transient electromagnetic pulse disturbances associated with the E1 and E2 phases of an EMP. A housing (901, 902) has a pair of AC mains wall plug prongs (905) extending from a side. When sustained electrical disturbances or transient electromagnetic pulse disturbances are detected, the apparatus provides a visual alarm (603, 609), audible alarm (608), and discrete indication signal (607) that can be used to disconnect (702) or redirect the flow of electrical power.

Abstract: 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.

Abstract: Methods, systems, and apparatus to facilitate a fault triggered diode emulation mode of a transistor. An example apparatus includes a driver to output a control signal to a gate terminal of a transistor of a power converter; and a diode emulation control circuit to, in response to determining a fault corresponding to the transistor, enable the transistor when current flows in a direction from a source terminal of the transistor to a drain terminal of the transistor.

Abstract: An overheat detection system comprising a controller for declaring the overheat, and two wiring connections running along a monitored system and configured to react upon overheat. The controller is configured to determine an electrical status of each wiring connection at least between operative and inoperative, the inoperative status corresponding to an electrical anomaly thereof, and electrically connect or disconnect the wiring connections depending on the electrical status thereof, wherein the declaration of overheat is based on a dynamic reconfiguration of the overheat detection system.

Abstract: A method for protecting an electronic system against a voltage surge, which electronic system is connected to a telecommunication network and includes a control integrated circuit, the method including successively connecting the electronic system to a remote server containing meteorological data; recovering meteorological data originating from the remote server; analyzing by the control circuit the recovered meteorological data to assign thereto a danger level of the current or imminent meteorological event; and, when the assigned danger level exceeds a main warning threshold: sending by the control circuit a warning signal to a display terminal connected to the electronic system; displaying a first warning message on the display terminal from information contained in the warning signal, the first warning message warning a user of the display terminal of a risk of voltage surge due to the current or imminent meteorological event; and electrical isolating a port of the electronic system.

Abstract: A system and method for detecting and isolating a high-altitude electromagnetic pulse (“HEMP”) along electrical lines electrically connected to a monitored infrastructure so as to protect the monitored infrastructure, the method including a phase unit receiving sensor signals from a plurality of sensors electrically connected to each of the electrical lines, respectively, upstream of and associated with the monitored infrastructure. The method includes determining if the received sensors signals associated with the respective electrical line is indicative of an E1 component of an EMP and, if so, actuating an isolation subsystem in less than 300 nanoseconds to electrically isolate the respective electrical line against propagation against the monitored infrastructure. Determining in real time if received sensor signals is indicative of the E1 component includes a hardware implemented neural network (NN) having algorithms for machine learning (ML) and artificial intelligence (AI) operable to provide instantaneous detection and classification.

Abstract: A monitoring apparatus has a control apparatus for monitoring a cooling apparatus for a power electronics arrangement. The control apparatus has an input and an output, which input is configured to receive a temperature signal from a temperature sensor, and to determine a temperature value depending on the temperature signal, and which output is configured to output an output signal. The control apparatus performs the following steps: ascertaining at least twice a temperature value and a time value assigned to the temperature value, ascertaining a difference quotient of the change in the temperature values to the change in the assigned time values, determining the state of the cooling apparatus of the power electronics arrangement depending on the ascertained difference quotient, outputting the output signal depending on the state in order to influence the power electronics arrangement.

Abstract: Method for SEL mitigation involves determining one or more base sets of signature vector components for each of a plurality of signal loading conditions experienced by a protected device in an operating state, each set of base signature vector components together comprising a base signature vector. The method further involves monitoring signature vector components for the protected device to determine a detected signature vector which is comprised of a set of detected signature vector components. The detected signature vector is compared to a dynamically selected base signature vector which is associated with the device state and signal loading condition which are currently active to differentiate between the occurrence of standard current surges associated with normal operation of the protected device and a non-standard current surge.
