Abstract: Various embodiments of a wirelessly powered local computing environment are described. The wireless powered local computing environment includes at least a near field magnetic resonance (NFMR) power supply arranged to wirelessly provide power to any of a number of suitably configured devices. In the described embodiments, the devices arranged to receive power wirelessly from the NFMR power supply must be located in a region known as the near field that extends no further than a distance D of a few times a characteristic size of the NFMR power supply transmission device. Typically, the distance D can be on the order of 1 meter or so.

Abstract: A portable electronic device is described. This portable electronic device includes an external housing with a cavity defined by an edge. A keyboard, having a front surface and a back surface, is disposed in the cavity with the front surface facing the external housing. Moreover, a tray is disposed over the back surface of the keyboard, and is mechanically coupled to the external housing adjacent to the edge. Furthermore, battery cells are mechanically coupled to an opposite side of the tray from the back surface of the keyboard. The tray may allow the battery cells to be removed from the portable electronic device without damaging the keyboard. In addition, the tray may increase the compression strength and/or the bending strength of the portable electronic device.

Abstract: An interposer for electrically coupling a battery-management circuit board in a power supply and a motherboard is described. The interposer includes: a substrate having a top surface and a bottom surface; first spring connectors, disposed on the top surface, which electrically couple to the battery-management circuit board; and second spring connectors, disposed on the bottom surface and electrically coupled to the first spring connectors, which electrically couple to the motherboard. Spring connectors in a first subset of the first and second spring connectors that convey power signals have a first vertical height, and spring connectors in a second subset of the first and second spring connectors that convey monitoring signals for the power supply have a second, smaller vertical height. In this way, the first subset is activated before the second subset is activated, thereby ensuring that an electrical path for the power signals is established first.

Abstract: A power supply for use in a portable electronic device is described. This power supply includes battery cells in separate locations that are electrically coupled by a power bus to a battery-management circuit board, which includes an integrated circuit with control logic that monitors the battery cells and that regulates charging and discharging of the battery cells. The battery cells are not enclosed in a common battery-pack housing so that the battery cells are mechanically separate from each other. Moreover, the battery-management circuit board is external to the battery cells and is not enclosed in the battery-pack housing. By excluding the battery-pack housing from the power supply, there may be more space available to expand the sizes, and thus the total capacities, of the battery cells.

Abstract: An apparatus for implementing bus request routing to allow functionality with 2 way or 4 way processors, includes a bus configured to provide bus request routing; and a bus request route switching stage coupled to the bus and configured to select a first route configuration if two processors are coupled to the bus. The switching stage is also configured to select a second route configuration if more that two processors are coupled to the bus. The switching stage determines if two or more processors are coupled to the bus. A logic block may be used to determine the required configuration based on the detected processor population.
