摘要： An optical switch assembly for a two-way radio has electrical and mechanical subassemblies. The electrical portion consists an IR emitter (12) and a pair of IR receivers (14,16) strategically positioned upon a printed circuit board (10). The mechanical portion consists of a rotatable interposer mechanism (20) interconnected to a knob (35) on the radio via a shaft (28). The interposer has inner (22) and outer (24) concentric cylindrical walls. The outer wall controls the light transmitted between the emitter and one of the receivers (16), ultimately controlling the On-Off state of the radio. The inner wall has an integrated gray-scale graphic which controls the transmission of light between the emitter and the other IR receiver (14), ultimately controlling the audio output of the radio.

摘要： A method (400) and system for illuminating a display screen (106) of a handheld electronic device (100) is disclosed. The system includes a transparent display screen cover (104), which is movably coupled to a housing (102) of the handheld electronic device. Further, the system includes at least one switch (206). The at least one switch is actuated in response to a user contacting the transparent display screen cover. The system also includes a control circuit (204), which causes the illumination of the display screen, in response to the activation of the at least one switch.

摘要： A system (50) including a telephone device having incorporated therein voice over Internet protocol (VoIP) adapter functionality. The system includes a VoIP adapter for coupling to a network, such as an Internet protocol (IP) network, and a telephone device, such as a cordless telephone device, for coupling to the VoIP adapter. The telephone device includes a base station and a plurality of handsets, such as cordless handsets. The telephone device is configured to include therein VoIP adapter functionality, such as subscriber integrated circuit (SLIC) functionality that conventionally resides in a conventional VoIP adapter. The incorporation of SLIC functionality and other VoIP adapter functionality into the telephone device reduces the overall cost of the system, e.g., by eliminating relatively expensive hardware, such as SLICs, and also reduces the relative complexity of the system, e.g., by simplifying several system component hardware configurations.

摘要： A residential gateway provides packet-switched telephony service over a broadband communications network. The gateway includes data terminal equipment having an interface for communicating with customer premises equipment. The gateway also includes a self-installation agent for generating signals that are rendered as audio prompts that guide a user through a process for installing the residential gateway so that packet-switched telephony services are available to the user through the customer premises equipment.
