  • Systems and Methods for Adjusting Audio Levels in a Plurality of Audio Signals
    Publication number: 20120257760
    Abstract: Systems and methods for adjusting audio levels in a plurality of audio signals are disclosed. One or more input signals containing one or more audio signals are depacketized. The audio signals are analyzed to determine if audio levels of the signals correspond to a desired audio level for at least some of the signals. The audio levels of signals that do not correspond are adjusted. Packets that do not require adjustment and the resulting adjusted packets are combined to form one or more output signals corresponding to the one or more input signals.

  • GRAPHICAL USER INTERFACE (GUI) FOR ADMINISTERING A NETWORK IMPLEMENTING MEDIA AGGREGATION
    Publication number: 20120224586
    Abstract: A graphical user interface (GUI) is disclosed that allows a user to identify routers, communities, residents and media aggregation managers existing on a network. The user may interactively select a path that includes two media aggregation managers and at least one router. The GUI predicts scheduled bandwidth utilization along the selected path for a variety of residents wishing to communicate across the path. The GUI may be utilized for initializing all media aggregation managers on the network along with provisioning each of the routers on the selected path. The GUI provisions all of the routers and initializes all of the media aggregation managers on the selected path simultaneously in order to accomplish the predicted schedule of usage provided by the GUI to the user and force all communication packets communicated between the residents to travel along the selected path.

  • Wide range and dynamically reconfigurable clock data recovery architecture
    Patent number: 8189729
    Abstract: Wide range and dynamically reprogrammable CDR architecture recovers an embedded clock signal from serial input data with a wide range of operating frequencies. In order to support a wide range of data rates, the CDR architecture includes multiple operating parameters. These parameters include various pre/post divider settings, charge pump currents, loop-filter and bandwidth selections, and VCO gears. The parameters may be dynamically reprogrammed without powering down the circuitry or PLD. This allows the CDR circuitry to switch between various standards and protocols on-the-fly.

  • Synthesis, capping and dispersion of nanocrystals
    Publication number: 20120088845
    Abstract: Preparation of semiconductor nanocrystals and their dispersions in solvents and other media is described. The nanocrystals described herein have small (1-10 nm) particle size with minimal aggregation and can be synthesized with high yield. The capping agents on the as-synthesized nanocrystals as well as nanocrystals which have undergone cap exchange reactions result in the formation of stable suspensions in polar and nonpolar solvents which may then result in the formation of high quality nanocomposite films.

  • Adaptive equalization methods and apparatus
    Patent number: 8155180
    Abstract: A system includes a programmable transmitter device (e.g., a PLD) connected to a programmable receiver device (e.g., another PLD) via a transmission medium for transmitting a high-speed data signal from the transmitter to the receiver. During a test mode of operation a low-speed communication link between the transmitter and receiver allows those devices to work together to transmit test signals having known characteristics from the transmitter to the receiver via the transmission medium, to analyze the test signals as received by the receiver, and to adjust at least some aspect of the system (e.g., equalizer circuitry in the receiver) to at least partly compensate for losses in the test signals as received by the receiver.

  • Interconnection and input/output resources for programmable logic integrated circuit devices
    Patent number: 7839167
    Abstract: A programmable logic integrated circuit device has a plurality of regions of programmable logic disposed on the device in a plurality of intersecting rows and columns of such regions. Interconnection resources (e.g., interconnection conductors, signal buffers/drivers, programmable connectors, etc.) are provided on the device for making programmable interconnections to, from, and/or between the regions. At least some of these interconnection resources are provided in two forms that are architecturally similar (e.g., with similar and substantially parallel routing) but that have significantly different signal propagation speed characteristics. For example, a major or larger portion of such dual-form interconnection resources may have what may be termed normal signal speed, while a smaller minor portion may have significantly faster signal speed.
