  • Electrical module cooling through waste heat recovery
    Patent number: 10636725
    Abstract: An apparatus includes a base, one or more first fins, one or more second fins and one or more thermoelectric generation units. The base may be thermally couplable to an electrical module that generates heat while operational. The first fins may be thermally connected to the base. The second fins may be thermally isolated from the base. The thermoelectric generation units may be (i) disposed between the first fins and the second fins and (ii) configured to convert a heat difference between the first fins and the second fins into an electrical signal at a port thereby cooling the electrical module.
    Type: Grant

  • Method for measurement of backup power supply capacitance in restraint control module
    Patent number: 6441592
    Abstract: A method and system for measuring the capacitance of a backup power source in a backup power supply system is disclosed by the present invention. The regulated output voltage is set to a nominal regulated output voltage during normal operation and then adjusted to a predetermined regulated output voltage during a capacitance measurement. A pair of predetermined loads is connected to the backup power source in consecutive order for discharging energy from the backup power source. A counter is used to count the time that elapses before the regulated output voltage reaches the lower regulated output voltage or the backup power supply system begins regulating. The resulting counts are used by a main control unit, together with several other known values, to determine the capacitance of the backup power source.
