    Abstract: A modular communication device (102), which provides for radio frequency (RF) communication in a communication system (100), comprises a first modular unit (106) and a second modular unit (108). The first modular unit (106) includes a housing (110); a user interface (113) including a display (114) and keys (116); electrical circuitry (605), including a transceiver (606) coupled to an antenna (610); a battery connection interface (308) for receiving a battery (302); and a connection interface (120). The second modular unit (108) includes a housing (128); a user interface (135) including a speaker (650), a microphone (648), and a keypad (140); a retractable antenna (134); a battery connection interface (402) for receiving a battery (142); and a connection interface (143). When the connection interfaces (143, 120) are connected, the user interface (135), the antenna (134), and the battery connection interface (402) are coupled to the electrical circuitry (602).

    Abstract: Un dispositivo (100) incluye una membrana (1600) de teclado numérico que incluye una capa conductora (1608) de membrana sobre la superficie de base del cuerpo (1602) de membrana. La capa conductora cubre las áreas de contacto (217) de la membrana y está conectada en la tierra mediante un adhesivo (1700). La capa conductora aterrizada en la membrana proporciona una proteccion a la RF para reducir el indeseable acoplamiento de la energía de RF a través del área de teclas del dispositivo.

    Abstract: A code division multiple access (CDMA) cellular telephone with reduced transmissions from the CDMA cellular telephone to a remote base station. A variable rate vocoder is operable to receive an input signal and encode the input signal at any of a plurality of frame rates responsive to an amount of audio content present in the input signal. A controller monitors an encoding rate of operation of the variable rate vocoder and detects when the variable rate vocoder operates at a predetermined rate. The controller then causes a transmitter coupled to the variable rate vocoder to reduces a duty cycle of operation.

    Abstract: A method for controlling diversity receivers in a wireless communication device includes the steps of: determining if the wireless communication device is experiencing poor coverage (220), using a first receiver and a second receiver for diversity (230) if the wireless communication device is experiencing poor coverage, and using the second receiver for scanning (240) if the wireless communication device is not experiencing poor coverage. Thus, diversity can be used when needed to improve reception. Both receivers, however, can be used in a non-diversity mode to reduce current drain or to speed up channel acquisition when coverage is not poor.
