Abstract: An apparatus and method for providing a selectively reduced voltage to a portable electronic device are disclosed. When a determination is made that an output voltage from a voltage source exceeds a predefined maximum permitted voltage, a plurality of circuitries, including an adaptive active current limiting circuitry, are enabled in order to derive the reduced voltage from the output voltage. The reduced voltage is at least at or below the predefined maximum permitted voltage and is supplied to the portable electronic device by battery circuitry that includes the active current limiting circuitry.

Abstract: A method and apparatus for a self-heating battery pack uses a battery cells of a first battery cell circuit to power a device. However these battery cells become substantially inoperative below a very cold temperature, so a second battery cell circuit, having a second type of battery cells which can operate at the cold temperature, is used to power a heating element to warm up the first battery cells to a temperature at which they can operate.

Abstract: A battery, method and battery operated portable communication device are provided with protection from excessive current and thermal conditions. A plurality of protection circuits are coupled in series within a common charge/discharge path of the battery. The first protection circuit is configured to block current by opening a switch in response to a voltage drop across the switch and a current sense resistor in the common charge/discharge path. The second protection circuit provides redundancy under conditions where the first switch might fail, where the second switch will block current through the current sense resistor.

Abstract: Battery circuitry forms part of apparatus for connecting a battery power source to a portable electronic device. The battery circuitry is configured to detect a transitioning of an enable signal, caused by actuation of a power switch, from a de-asserted state to an asserted state. In response to detecting the transitioning of the enable signal, the battery circuitry is further configured to open an electrical path within the battery circuitry. The path, when opened, connects the battery power source in a manner that permits powering on of the portable electronic device.

Abstract: An apparatus, device, and charging system are provided. The apparatus comprises a primary stationary receive coil and a secondary rotatable receive coil, the primary stationary receive coil being electronically coupled to the secondary rotatable receive coil. The secondary rotatable receive coil provides a charge mode position when rotated in a same plane as the primary stationary receive coil. The secondary rotatable receive coil provides non-charge mode position when retracted back against the primary stationary receive coil. The coils may be coupled is series and or parallel configurations. The primary stationary receive coil may be integrated within or appended to a housing. The secondary rotatable receive coil may be integrated within or coupled to a rotatable clip coupled to the housing. Rotation of the clip extends a charging configuration with which to charge the primary stationary receive coil and the secondary rotatable receive coil.
