    • A networking system for wirelessly transmitting a signal between one or more computers. The system includes, in a first transceiver pair, an upper transceiver configured to be coupled to be suspended overhead and lower transceiver configured as a ground unit. The upper and lower transceivers include an RF transmitter configured to transmit a first signal as a focused beam toward the opposing transceiver and an RF receiver configured to receive the first beam signal from the opposing transceiver. The system also includes, in a second transceiver pair, an RF transmitter configured to transmit a second signal as a focused beam toward the opposing transceiver and an RF receiver configured to receive the first beam signal from the opposing transceiver. The first and second beam signals are transmitted at a 60 GHz, allowing the first and second beam signals to be transmitted at a beam spread of less than 5 degrees.

    • A digital intercom device consistent with certain embodiments uses power line communication (PLC). A power line interface connects to a power line serving as a communication medium. An audio codec is coupled to the power line interface for encoding and decoding digital data to and from data suitable for use by the power line interface. A digital to analog converter receives digital decoded data from the codec and converts the digital coded data to a received analog signal. A receive audio amplifier amplifies the received analog signal to a level adequate to drive a speaker. A transmit audio amplifier amplifies a transmit audio signal and provides an amplified transmit audio signal as an output. An analog to digital converter converts the amplified transmit audio signal to a digital representation thereof and passes the digital representation to the codec. A control processor controls operation of the interface and the audio codec. A switch interface receiving a signal from a push-to-talk switch, which causes the codec to encode the digital representation and the power line interface to place an OFDM modulated version of the digital representation onto the power line. This abstract should not be considered limiting since other embodiments may incorporate more, fewer or different elements that those described in this abstract.

    • The present invention provides a method and apparatus for rendering an input video stream as a polygon texture. The method provides process steps to receive the input video data in a Mip Map generator, wherein the Mip Map generator converts the video data to Mip Map data and stores the Mip Map data in a first memory storage device; wherein the first memory storage device is located in a V buffer. The method further includes sending a data set from a Z buffer to V buffer and mapping the data set to RGB values at a texel address in the V buffer memory. The data set includes U, V and Z coordinates, Mip Map level and channel identification data. The V buffer includes a V buffer fetch module that receives the data set from the Z buffer and maps to RGB data within V buffer memory.

The device is configured to store a first value, a second value, a first offset value, and a second offset value. The first value represents a Z value of a first sub-fragment and the second value points to a sub-fragment location that corresponds to the first sub-fragment. The first offset value represents an offset value of the first value in x-direction and the second offset value represents an offset value of the first value in y-direction. The processor is configured to perform an anti-aliasing function using the first value, the second value, the first offset value, and the second offset value.
