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

Flat-profile keypad assembly and label

A radiotelephone ( ) has a display ( ) that efficiently presents information such as lists and text fields. For each list, the display ( ) presents a title message ( ) with unique identification markings ( ), an end-of-list indicator ( ), and a dynamic scroll indicator ( ) to indicate scrolling directions. A context-sensitive symbol ( ) is displayed whenever a context sensitive menu is available for a highlighted item. A search function is incorporated to allow expert users to quickly find information. A notepad feature allows the most recent string of user input data to be stored and recalled so that the data is not accidentally appended to subsequently entered data. Specialized data entry modes such as an editor screen ( ), an editor-with-list screen sequence, a set value list screen sequence, a toggle value screen sequence, and a form screen sequence provide efficient retrieval, display, and entry of information.

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.

A portable communication device (100) comprises a first housing element (202) and a second housing element (204), wherein the second housing element (204) is movingly connected to the first housing element (202) such that the second housing element (202) is settable to substantially three positions. A sensor (112) coupled to the first housing element (202) and the second housing element (204) produces a position signal to indicate the position of the second housing element (204) relative to the first housing element (202), and an activation element (230) produces an activation signal in response to a user input. A controller (106) operates the portable communication device (100) in one of a standby mode, a private-mode, and a speakerphone mode in response to the position signal and the activation signal.
