Abstract:
An n bit D/A decoder is formed using P-type and N-type transistor switches, instead of convention CMOS switches. Each P-type and N-type switch may be formed of fewer transistors than those used to form a CMOS switch, thereby reducing the overall transistor count. The decoder may be used to decode digital values to non-linear GAMMA corrected analog output voltages.

Abstract:
Systems and methods are provided for supporting an external display on a portable device. A system on a chip (SOC) of the portable device provides a first set of graphics data to a graphics controller. The embedded graphics controller renders the first set of graphics data for output using an LCD screen integrated with the portable device. The SOC renders a second set of graphics data and provides rendered graphics data to an external display interface. The external display interface formats the rendered graphics data for output on an external, remote display.
Abstract:
A communication device is coupled to an analog telephone and a packet network. The communication device detects an off-hook condition for the analog telephone and transfers a dial tone to the analog telephone, detects digit tones from the analog telephone that indicate a called number and responsively transfers a first message indicating the called number to the packet network, receives a second message from the packet network indicating that a called party associated with the called number is being alerted and responsively transfers a ring tone to the analog telephone, receives a third message from the packet network indicating that the called party has accepted the communication session and responsively stops the transfer of the ring tone to the analog telephone, exchanges analog voice signals with the analog telephone, exchanges voice packets with the packet network, and interworks between the analog voice signals and the voice packets.
Abstract:
A communication device is coupled to a packet network and includes two ports coupled to two analog telephones. The communication device receives a message from the packet network indicating a called number and processes the called number to select one of the ports and to transfer a ring signal through the selected port to ring the analog telephone. The communication device transfers a message to the packet network indicating that a called party is being alerted, detects an off-hook condition for the analog telephone and stops the transfer of the ring signal, transfers a message to the packet network indicating packet routing information for the communication session, exchanges analog voice signals with the analog telephone through the selected port, exchanges voice packets with the packet network using the packet routing information, and interworks between the analog voice signals and the voice packets.
Abstract:
A fishing rod alert device is provided that monitors the motion of a fishing rod and sends a wireless alert to a user's handheld device when the lure of the fishing rod is struck by a fish. The device comprises an elongated member with a series of attachments that secure the device along the length of a fishing rod. The device includes a processor, a motion sensor, and a radio frequency transmitter. Motion of the fishing rod is detected by the motion detector, which sends signals to the processor. Upon determining that a fish has struck the line based on the motion signals, the processor directs the transmitter to send radio frequency signals over a network or directly to a user's handheld electronic device. The handheld electronic device receives the signals and alerts the user though one or more means.
