  • Patent number: 10530179
    Abstract: An integrated external controller/charger system for an implantable medical device is disclosed comprising an external controller/charger device with a Graphical User Interface (GUI) and first battery, and an external charging coil assembly coupleable to the external controller/charger device and including or associated with a second battery. The second battery is used to energize a charging coil in the external charging coil assembly, while the first battery is used to power other aspects of the system (data telemetry circuitry, control circuitry, the GUI, etc.). Because the second battery powers the relatively high-power charging function, the first battery in the external controller/charger device can be made smaller. Additionally, the second battery enables a suitable external controller device (e.g. a mobile device such as a cell phone) to provide charging functionality even if its first battery is otherwise inadequate.

  • Patent number: 10500979
    Abstract: An electric vehicle charging system, for use with an electric grid having live conductors including a charging conductor, and a neutral conductor. The electric grid has a grid usage level and a grid capacity. The charging system includes a plurality of stages that each include a battery charger for charging an electric vehicle battery, a controller, and a charging relay. A current sensing unit inductively measures the current on the charging conductor and provides a sensed current to the controllers. When the grid usage level is low the battery chargers on all stages are active. As the grid usage increases toward peak usage, in response to an increase in the sensed current, the controllers consecutively deactivate the battery chargers at predetermined threshold levels.

  • Patent number: 10505403
    Abstract: A wireless power transmitting device transmits wireless power signals to a wireless power receiving device. To detect foreign objects, the wireless power transmitting device has an array of temperature sensors. The array of temperature sensors may include temperature sensor components such as temperature sensitive thin-film resistors or other temperature sensitive components. A temperature sensor may have thin-film resistors formed on opposing sides of a substrate. The thin-film resistors may be formed from meandered metal traces to reduce eddy current formation during operation of the wireless power transmitting device. Signal paths coupling control circuitry on the wireless power transmitting device to the array of temperature sensors may be configured to extend along columns of the temperature sensors without running along each row of the temperature sensors, thereby reducing eddy currents from loops of signal routing lines.

  • Patent number: 10491014
    Abstract: A computer-implemented method extends the time until the battery reaches an over-discharged state of an information handling system during storage. The method comprises determining if a first battery parameter is outside an associated first battery parameter specification. When the first battery parameter is outside the associated first battery parameter specification, a power management controller isolates the battery by turning off a charge/discharge field effect transistor. The method also includes determining if the first battery parameter is outside an associated second battery parameter specification. In response to the first battery parameter being outside the associated second battery parameter specification, the power management controller is triggered to enter a minimum power state to further reduce power consumption from the battery.
