Abstract:
A configurable, force-sensitive input structure for an electronic device is disclosed. The input structure has a metal contact layer, a sense layer positioned below the metal contact layer, and a drive layer capacitively coupled to the sense layer. The input structure may also have a compliant layer positioned between and coupled to the sense layer and the drive layer, a rigid base layer positioned below the drive layer, and a set of supports positioned between the metal contact layer and the rigid base layer.
Abstract:
A power supply for use in a portable electronic device is described. This power supply includes a battery-management circuit board and battery cells. The battery cells include subsets of battery cells in which at least some of the battery cells have different capacities. For example, at least some of the battery cells in the subsets may have different geometric sizes. Furthermore, the battery cells in each of the subsets are electrically coupled to the battery-management circuit board so that each of the subsets has a common total capacity.
