Abstract: A method for a keypad assembly including a keycap layer 110 having multiple user interface key caps flexibly coupled to a carrier portion, a luminescent layer 120 disposed toward a backside of the plurality of key caps, the luminescent layer carrying a plurality of switch domes each aligned with a corresponding one of the plurality of key caps of the key cap layer. In some embodiments, a backing material is applied to a backside of the user interface key caps.

Abstract: A keypad including a plurality of user interface key caps flexibly coupled to a carrier and forming a substantially planar unitary member. The user interface key caps defined by and located between nested slots formed in the substantially planar unitary member wherein the nested slots are devoid of a material from which the plurality of user interface key caps and the carrier are formed. A flexible web is disposed the slots between the plurality of user interface key caps, wherein the plurality of user interface key caps, the carrier and the flexible web constitute a unitary member.

Abstract: A portable telephone (100, 700) such as a flip type cellular telephone is provided with a pivoting head (112, 710), that includes a multipurpose auxiliary display (118, 720), and a camera (122, 716). The pivoting head facilitates using the camera to capture pictures of the user of the cellular telephone, or of a scene that the user is observing.

Abstract: A slider mechanism (414) includes a first element (516), a second element (518) and a biasing device (590). The second element (518) slides with respect to the first element (516) along a path. The biasing device (590) functions as an over-center mechanism, such that external force is required to move the slider mechanism (414) for an initial range of its travel, and stored energy is used to move the slider mechanism (414) along a subsequent range of its travel. The biasing device (590) includes a pair of springs (524, 522) that are under compression. The springs (524, 522) are accommodated in openings (530, 532, 534) formed in the first and second elements (516, 518) and the springs (524, 522) move in a plane of the mechanism (414) to reduce the thickness of the slider mechanism (414).

Abstract: A removable battery door clip has opposed pivoting stubs (176) for the door to be pivotally anchorable to a housing (20) and at least one projection (152) for the door to be snappably fastened with at least one retaining slot (234) of the housing.

Abstract: A resilient latch (70) and a method of attaching the latch to a pair of interlocked housings (50) having a recessed border and mating cavities (377) in the recessed border. Placed around the border of the paired housings, the latch having protrusions (727) engages with the cavities of the paired housings, as the latch is slid around the border.
