  • Method and apparatus for detecting the presence of a wireless network
    Patent number: 7010298
    Abstract: A system and method for detecting the presence of a wireless LAN. The system includes a radio frequency receiver for receiving radio frequency signals and a controller having associated programming for controlling the receiver. The programming also functions to measure and analyze the energy of the received radio frequency signals for the purpose of determining if the radio frequency signals indicate the presence of a wireless LAN or are being produced by a noise generating electronic device.
    Type: Grant

  • Automatic longitudinal balance for solid state DAAs
    Publication number: 20030076945
    Abstract: Systems and methods are utilized to balance differential gains and thereby improve signal-to-noise ratio where information is transmitted across differential signal lines. Adjustable impedances are selectively applied to one or more of the differential signal lines in order to more closely match the gains on the signal lines. As a result, signal-to-noise ratio is improved. In a preferred exemplary embodiment, a plurality of impedance elements are selectively connected to one or more differential signal lines in order to adjust the differential gain between the two signal lines such that they are essentially equal thereby improving the overall signal-to-noise ratio.
