20140254108 | THERMAL ISOLATION IN PRINTED CIRCUIT BOARD ASSEMBLIES - A printed circuit board assembly for reducing the impact of heat generated from circuitry within a handheld or non-handheld device is provided. The printed circuit board assembly may include a printed circuit board comprising a plurality of conductive layers and a plurality of dielectric layers where each dielectric layer is disposed between a pair of conductive layers. Each conductive layer may include a first portion and a second portion separated by a gap where the gaps in the alternating conductive layers are misaligned. The first portion of each conductive layer may be substantially thermally isolated from the second portion of each conductive layer. | 09-11-2014 |

20140160699 | METHODS AND APPARATUS FOR CONFORMAL SHIELDING - Methods and apparatus for providing conformal shielding are disclosed to provide electromagnetic interference shielding of circuit components mounted on a circuit board. A print mold stencil is provided with one or more conductive shielding walls disposed within the stencil before its application to the circuit board and detachable therefrom, and also configured to encompass the circuit components. In this manner a shielded compartment volume is defined by walls of the print mold stencil and one or more of the conductive shielding walls, and may be easily and quickly applied to the circuit board to encompass the components for shielding. A conformal shielding layer is then formed from a molding material disposed in the shielded compartment volume that encompasses the components, as well as a conductive layer disposed on the outer surface of the material, and coupling of the shielding walls with a ground plane in the circuit board. | 06-12-2014 |
20140365790 | BATTERY POWER MANAGEMENT FOR A MOBILE DEVICE - Techniques for managing battery power of a mobile device are described. In an aspect, battery power may be reserved for an application prior to execution of the application on the mobile device. The reservation may ensure that the application has sufficient battery power for execution. In another aspect, battery power may be allocated to applications based on their priorities. The applications may be ordered based on their priorities, and the available battery power for the mobile device may be allocated to one application at a time, starting with the highest priority application. In yet another aspect, battery power may be allocated to applications based on a battery discharge curve for the mobile device. An operating point on the battery discharge curve may be selected based on at least one objective. The available battery power may be determined based on the selected operating point and allocated to the applications. | 12-11-2014 |
