  • Patent number: 11686758
    Abstract: An arc fault detection device for detecting an arc fault in an electric line includes a first terminal and a second terminal for connecting the arc fault detection device to a conductor of the electric line. A sensor is adapted for generating a sensor signal from a current through the electric line; and a controller is adapted for detecting the arc fault from the sensor signal. The sensor includes an inductor connected to the first terminal and the second terminal and a capacitor connected in parallel with the inductor. The inductor and the capacitor form a resonant circuit with a resonance frequency, the resonance frequency determining an impedance behavior of the resonant circuit; wherein the inductor and the capacitor are chosen such that the impedance behavior of the resonant circuit corresponds to a desired impedance behavior over a relevant frequency range of the current through the electric line.

  • Patent number: 11689014
    Abstract: An ESD protection circuit in an interface circuit has a first diode coupled between a first power source of an integrated circuit device and an input/output pad of the integrated circuit device, a second diode coupled between a second power source of the integrated circuit device and the input/output pad, and a resistive element that couples the second diode to the first diode and to the input/output pad. The first power source supplies a driver circuit coupled to the input/output pad. The second power source supplies one or more core circuits of the integrated circuit device. The resistive element may be implemented as an interconnect configured to provide a resistance that produces a voltage differential between a terminal of the second diode and a corresponding terminal of the first diode during an electrostatic discharge event.

  • Patent number: 11689015
    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.

  • Patent number: 11653437
    Abstract: Provided is a method for making a composite structure with exposed conductive fibers. The exposed conductive fibers can be used for static dissipation. In the present method, a liquid, gum, gel, or impermeable film mask is applied to the conductive fiber material. The mask functions to prevent infiltration of curable liquid resin into the conductive fiber material. The masked conductive fiber material is incorporated into the composite structure, along with structural fiber material. The liquid resin is cured. The mask material and cured resin are removed from the masked areas, thereby exposing the conductive fiber material. The exposed conductive fiber material can collect and drain electrostatic charges. The present method can be used to make storage tanks and other objects that require electrostatic charge dissipation.
