  • Patent number: 10317966
    Abstract: A voltage regulation (VR) module of an Information Handling System (IHS) operates a switching direct current to direct current (DC-DC) voltage regulation (VR) power circuit in a constant current mode at a constant current level. The VR module approximates the capacitance value of the output capacitive load at the output terminal of the switching DC-DC VR power circuit based upon a time interval for output voltage to reach a threshold. The VR module then operates the switching DC-DC power circuit in constant output voltage mode using one group of VR operating settings to optimize performance for the capacitance value of the output capacitive load.

    Abstract: An electronic control unit of a drive assist apparatus acquires electric power source identification information for identifying a source of an electric power currently charged in a battery and electric power amount information representing an electric power amount corresponding to the source from an electric power acquisition unit, thereby recognizing a battery remaining amount SOCrg representing a green electric power, a battery remaining amount SOCj representing a privately generated green electric power, and a battery remaining amount SOCrs representing a non-green electric power. The unit presents travelable ranges each formed by connecting a group of maximum reachable points to which a PHV can reach by using each of a battery total remaining amount SOCr and the battery remaining amounts SOCrg, SOCj, and SOCrs to a user (driver) by using an information presentation unit.

  • Patent number: 10102594
    Abstract: Mandatory and optional consumption points are identified to support management of power allocation. A mandatory consumption point is a consumption point required to function at a given time and an optional consumption point is a discretionary consumption point. The energy required for mandatory consumption points to complete their designated functions is calculated. An energy quota is designated for power allocation to the optional consumption points in response to the mandatory consumption point calculation, and the identification of available energy. Energy required for optional consumption points to complete their designated functions is calculated. The optional consumption points are dynamically prioritized and power is allocated to the optional consumption points responsive to this prioritization and with respect to the designated energy quota.

  • Patent number: 10079502
    Abstract: A power management system for dispensers is described. The system includes a controller connected to a lower power zero net voltage (ZNV) power source. A power rectification circuit (PRC) converts ZNV power to higher voltage direct current (HVDC) power. An energy storage system connected to the HVDC power source receives and stores HVDC power within the energy storage system which is selectively provided to a dispenser motor load connected to the energy storage system. The system provides an effective solution to the problem of transferring power from a low power battery source on a disposable product to a dispenser as well as providing a system that minimizes corrosion at the electrical interface between the disposable product and the dispenser particularly in higher humidity environments.

  • Patent number: 10066794
    Abstract: A charging process of a rechargeable lighting device is controlled by a software algorithm and a microcontroller configured within the rechargeable lighting device which has first and the second charging contacts located on its exterior and the charging circuit is turned on when a cradle detection circuit detects that at least one of the charging contacts engages an electrical contact when the rechargeable lighting device is inserted into a charging cradle. The charging process begins with a charge-current which is constant and a battery charge-voltage which rises up to a nominal battery charge-voltage. The rechargeable lighting device recovers to a preselected condition through use of a power interruption avoidance algorithm configured within the microcontroller when there is a loss of power to the microcontroller of less than a preselected amount of time.
