  • Patent number: 9377767
    Abstract: An apparatus for a circuit which allows a user to connect various adaptors to a common interface to provide a device with power and data signals. The circuit may provide a device, in which the circuit is incorporated, with the ability to discern whether a connected adaptor is providing power or data at any given time. If the adaptor is providing power at a particular moment, then the power/data circuit can identify that power is being provided and signal the device to accept power. When the adaptor is providing data at a particular moment, then the circuit can identify that power is being provided and signal the device to accept power. The circuit may include a power/data input, a vehicle connector, an internal power source connector, a reference voltage source, a comparator, and sensor.

  • Patent number: 9358399
    Abstract: An external charger for a battery in an implantable medical device and charging techniques are disclosed. Simulation data is used to model the power dissipation of the charging circuitry in the implant at varying levels of implant power. A power dissipation limit constrains the charging circuitry from producing an inordinate amount of heat to the tissue surrounding the implant, and duty cycles of a charging field are determined so as not to exceed that limit. A maximum simulated average battery current determines the optimal (i.e., quickest) battery charging current, and at least an optimal value for a parameter indicative of that current is determined and stored in the external charger. During charging, the actual value for that parameter is determined, and the intensity and/or duty cycle of the charging field are adjusted to ensure that charging is as fast as possible, while still not exceeding the power dissipation limit.

  • Patent number: 9312570
    Abstract: Systems and methods for a demo mode for a computing device are disclosed. In some implementations, a computing device receives a first input for entering a demo mode. The computing device prompts, in response to the first input, for a user input indicating whether the user wishes to place the computing device in the demo mode. The computing device receives the user input indicating that the user wishes to place the computing device in the demo mode. The computing device enters the demo mode responsive to the user input indicating that the user wishes to place the computing device in the demo mode. Entering the demo mode includes adjusting battery settings of the computing device.

  • Patent number: 9293940
    Abstract: An apparatus and a method stabilize a charging current when recharging a battery in a device that uses a rechargeable battery. The device includes a charge module and a controller. The charge module provides a charging current to the battery, and operates in at least one of a Constant Current (CC) mode that maintains the charging current at a fixed value while the battery is charged, and a Constant Voltage (CV) mode that maintains a battery voltage at a reference value. The controller controls the charge module to operate in the CC mode when starting charging, controls the charge module to operate in the CV mode when the battery voltage reaches the reference value, and controls the charge module to operate in the CC mode for at least one time duration after the battery voltage reaches the reference value.
