Abstract: A holster for a handheld electronic device. The holster has integrated therein one or more piezoelectric elements that provide an output voltage to the handheld electronic device upon insertion of device in the holster. The output voltage can be used to charge the battery of the device, to power, at least in part, the device, or both. The output voltage is generated by harvesting vibration energy at the piezoelectric elements upon the holster being subjected to acceleration caused by a user carrying the holster when walking, running, or during any other suitable activity.

Abstract: A method of hot-swapping in a portable electronic device having at least two power sources comprising determining one of the at least two power sources requires replacement; confirming that the portable electronic device is being powered by another of the at least two power sources; and transmitting an indication that the power source requiring replacement may be replaced without shutting down the portable electronic device.

Abstract: Various apparatus and methods are described for moving air in a portable electronic device for purposes such as cooling. In a typical embodiment, the apparatus comprises an airflow-generating device and a vibration component. The vibration component may be used to drive the airflow-generating device. Further, techniques are described in which the airflow-generating device may be driven without causing the portable electronic device to vibrate.

Abstract: An electrical power source for a portable electronic device. The electrical power source includes at least one fuel cell adapted to receive fuel and generate therefrom electrical power for powering at least one component of the portable electronic device, a fuel tank adapted to provide fuel to the fuel cell, and at least one thermoelectric module in thermal contact with at least one of the fuel cell and fuel tank for regulating the temperature of the at least one fuel cell and at least one fuel tank.

Abstract: A method for producing a flexographic plate that includes a base layer and a layer of a photosensitive material fixed on the base layer. An image is produced on the photosensitive layer by selective reticulation. Areas to be reticulated are exposed to amplitude-modulated laser light with a wavelength ranging from 390 to 410 nm, which scans the surface of the photosensitive layer. The non-reticulated areas are then removed.

Abstract: The disclosure is directed at a method and apparatus for controlling fuel cell operating characteristics. In certain situations, the operating efficiency of fuel cells is degraded to external conditions. Providing a method and apparatus to control operating conditions for the fuel cell assists in improving the operating efficiency. This can be achieved by controlling certain environmental conditions, such as temperature and relatively humidity, in the area surrounding the fuel cell.
