Abstract: A carrying case for controlling a mobile device is provided, the carrying case comprising: a body enabled to mate with a mobile device to physically protect the mobile device; at least one input device, the body comprising the input device; a processor enabled to control communications with the mobile device; a power interface enabled to receive power from the mobile device to power the processor; and, a data interface enabled for relaying the communications between one or more of the at least one input device and the processor, and the mobile device, for controlling applications at the mobile device.

Abstract: A wireless device for providing notifications associated with a mobile electronic device is provided. The device comprises: an indicator; a body enabled to mate with a mobile electronic device, the body comprising the indicator such that when the body is mated to the mobile electronic device, the indicator is not obscured by the body; an induction device for wirelessly receiving signals from the mobile electronic device to control the indicator; and, a circuit connecting the induction device to the indicator, the circuit enabled to receive the signals and control the indicator in response thereto.

Abstract: Various embodiments are described herein for a peripheral device and a method of identifying the peripheral device via power cycling. In one embodiment, the method comprises obtaining characteristic information about the peripheral device, encoding the characteristic information in a power signal at the peripheral device and sending the power signal to an electronic device that is operably connected with the peripheral device. The electronic device can then take action such as adjusting its settings or applications based on the characteristic information of the peripheral device.

Abstract: A multi-battery system comprises a circuit having a circuit positive terminal and a circuit negative terminal. At least two batteries are provided to combine to deliver required system power. The batteries are connected to a protection circuit, an energy storage device, a system output voltage sensor and a logic gate. The protection circuit generates a protection signal and the voltage sensor generates an enabling signal that are fed into the logic gate as true signals to generate a true control signal. The true control signal causes the energy storage device to discharge. The digital enabling signal for each of the circuits is time-shifted by a time “t” so that at any time one of the circuits is discharging and one of the at least two circuits is charging during said time “t”.

Abstract: A multi-battery system for high-voltage applications with proportional power sharing comprises a circuit having a circuit positive and a circuit negative terminal. At least two batteries are provided to combine to deliver required system power. The batteries are connected to a protection circuit, energy storage means, system output voltage sensing means and a logic gate. Protection means generates a protection signal and the voltage sensing means generates an enabling signal that are fed into the logic gate as true signals to generate a true control signal. The true control signal causes the energy storage means to discharge. The digital enabling signal for each of the circuits is time-shifted by a time “t” so that at any time one of the circuits is discharging and one of the at least two circuits is charging during said time “t”.
