  • Publication number: 20210336451
    Abstract: A charge system for a vehicle includes a battery charge path, a current limiting element, and a capacitor. The current limiting element is arranged in series along the battery charge path, and in parallel relative to the capacitor. During an inrush event, the current limiting element is configured to initially restrict current flow between the battery and the load, increasing the rate and amount with which the capacitor is used to meet the current demands of the load. Thus, the current limiting element allows the battery to gradually increase its supply of current to the load in a manner that does not jeopardize its health. Once a steady state level of charging has been reached, the current limiting element is able to reduce its resistance to current flow, and the battery is able to safely take over as the primary source of current to the load.

  • Publication number: 20210336452
    Abstract: A power system includes a battery charge path and capacitor charge path arranged in parallel. During an inrush event, a current limiting element restricts current flow along the battery charge path to relieve battery stress. During the inrush event, current flow between the battery and load along a bypass path is also prevented by a switch element. Under steady state charging conditions, the resistance of the current limiting element decreases, thus increasing current flow between the battery and load along the battery charge path. During steady state conditions, a switch circuit controls operation of the switch element to also allow current flow between the battery and load along the bypass path. The change in the resistance of the current limiting element and/or actuation of the switch element by the switch circuit are optionally based on changes in temperature, and are passively effectuated without requiring an external control input signal.

  • Patent number: 11114257
    Abstract: Some embodiments are directed to an apparatus for detecting and suppressing DC electric arcs at a component, and are particularly adapted for vehicle wiring harnesses. The apparatus can include a detector circuit electrically connected to input and output terminals so as to be electrically connected in parallel to the component, the detector circuit being configured to detect a significant voltage spike across the component upon the component actuating between open and closed positions. The detector circuit can also be configured to transmit a control signal upon detecting the significant voltage spike. The detector circuit can include multiple circuit elements, enabling both the detection of the significant voltage spike and the transmission of the control signal, that are directly electrically connected to each other. A switching circuit conducts electricity from the power source side of the component to the load side of the component upon receipt of the control signal.

  • Publication number: 20200354800
    Abstract: Sensitive and specific detection of nucleic acids can be achieved using a chemical ligation-based template assisted rapid assay (TARA-L) with simple chemical reactions between probes and without the need for enzymes. Probes are designed to form a ligation product when they anneal to adjacent portions of a target nucleic acid. The ligation products can be detected, such as in immunochromatographic assays. The methods allow for the fast, efficient analysis of biological samples for the presence of nucleic acids and can be used, for example, in point of care settings.
