Abstract: A display frame for a mobile device includes a first display frame section and a second display frame section. A flexible hinge section couples the first display frame section and the second display frame section. The flexible hinge section enables the first and second display frame sections to bend relative to each other. A first wall is contiguous with the first display frame section, the flexible hinge section, and the second display frame section. The first wall is integral to the first display frame section, the flexible hinge section, and the second display frame section.

Abstract: A keypad apparatus includes a printed circuit (110) configured for a keypad. Dome actuators (108) are placed on top of the printed circuit. A backlight (106) with apertures (103) is placed over the dome actuators such that the dome actuators rest entirely within their associated apertures. This assembly is covered with a retainer (104) placed on top of the backlight to form a flat-profile keypad that can be used on an exterior of a phone housing (112). The retainer can be labeled to define the key functions, or a preferred replaceable key label (102) can be placed over the retainer. This provides an integral assembly with key labels that are easily customized.

Abstract: A communication device with an extending hinged flip apparatus includes three interconnected movable housings. A base housing includes a user interface and most of the electronics of the device. A flip housing is coupled by a hinge assembly to the base housing. An extendable housing is configured to slideably engage the base housing. A latch mechanism mechanically coupling the flip housing to the extendable housing in a latched position. When the latched is released, the flip housing rotates out and the extendable housing extends to provide a device with a length that is effectively more than double the device length in the latched position.

Abstract: A wireless infrared peripheral interface for a communication device having a cellular radio transceiver includes a peripheral interface. The peripheral interface includes at least one infrared signal source and at least one infrared detector. The signal source and detector are coupled with dispersing optics. An interface circuit is coupled to the infrared signal source and detector. A processor is coupled to the interface circuit, wherein the processor controls the interface circuit to process data signals that are conveyed through the infrared source and detector so as to communicate with a peripheral device that is proximate to the communication device. The dispersing optics reduces the dependency of optical alignment between the infrared data ports of the peripheral device and communication device.

Abstract: A multi-function antenna system for a radio communication device includes a housing that encloses a radio frequency transceiver of the radio communication device. A mounting base is coupled to the housing and has a first set of electrical contacts coupled to the transceiver. An antenna element is coupled by a hinge to the mounting base and has a second set of electrical contacts. Different portions of the first and second set of contacts are connectable as a function of the relative positions of the mounting base and the antenna element so as to provide different antenna functions.
