Abstract: A user interface device of a wireless communication device in which one or more of the keys on the user interface are fluorescently illuminated when the user interface is in active mode. One or more keys may include a layer including an opaque film area and a non-opaque area, such as an aperture in the opaque film area in the shape of indicia, such as a number, letter or function indicator. The opaque film area blocks illumination, and the non-opaque area allows illumination to pass through it. Fluorescent ink at the non-opaque area of a key fluoresces when illuminated in active mode, providing fluorescent indicia viewable by a user.

Abstract: A battery pack (12) for connection to an electronic product (10) having mating contacts (22, 24, 26, & 28) comprises a housing (11), an energy storage device (15) located within the housing for storing a charge, a first contact (38) and a second contact (36) coupled to the energy storage device and exposed externally from the housing. Circuitry couples to the energy storage device and provides at least the interconnection between the first and second contact and the energy storage device. Additionally, there is at least a third contact (34) exposed externally from the housing and coupled to at least one electronic device (42) within the housing. Finally, the battery pack has a connecting scheme for connecting the first and second contact of the battery pack to the product before the connection of the third contact to the mating contact on the electronic product.
