  • Patent number: 8135098
    Abstract: Systems and methods are provided for computing soft information for digital information based on a received signal, where the received signal suffers from noise and interference. A receiver that decodes the received signal may estimate channel information, such as the channel gain, associated with the interfering source. The receiver may also obtain modulation information through a backbone network or by decoding control information transmitted by the interfering source. Using the modulation information and the channel information, the receiver may estimate the effect that interference has on the received signal, and may compute soft information (e.g., a log-likelihood ratio) for the digital information.

  • Publication number: 20120059044
    Abstract: Methods of utilizing the arrestin-2/sTAM-1 complex as a therapeutic target. The methods include treating cells of a living organism to mediate an interaction between arrestin-2 and STAM-1 adapter protein molecules, wherein the interaction is characterized by the arrestin-2 adapter protein molecule directly binding to the STAM-2 adapter protein molecule. Pharmacological agents can be identified for therapeutic uses by determining whether the pharmacological agent disrupts the interaction between the arrestin-2 and STAM-1 adapter protein molecules.

  • Patent number: 8130768
    Abstract: A network gateway is disclosed, wherein for a received communication, the gateway determines a network component to which information for the communication is routed based upon one or more of: (a) a characterization of the source of the communication, (b) a characterization of non-address data in the communication, and (c) services applied to the communication by the gateway. The characterization of the communication source can be related to a perceived risk that the communication may be illicitly compromised or may cause a malfunction in a network component. The characterization of non-address data identifies a use of the communication, or service to be applied to the communication prior to reaching its destination, or a security feature (or lack thereof) of the communication. The services applied by the gateway are generally generic services for facilitating appropriate non-malicious communications, e.g.

  • Patent number: 8130519
    Abstract: A power supply circuit for powering a load at constant current has a rectifier stage for receiving an AC voltage input and for producing a first substantially DC voltage. A first capacitor is attached to the load. A charge-pump is attached to an output of the rectifier stage and to the load for providing power factor correction and for converting the first substantially DC voltage to a second substantially DC voltage at the first capacitor. The charge pump is prevented from conducting energy back into the output of the rectifier stage. The charge pump delivers energy to a charge pump output, the energy being delivered directly instead of being stored. A converter stage is attached to the load and the first capacitor. The converter stage is used for converting voltages at the first capacitor and the charge pump to an output DC current. The converter stage has a switch for periodically connecting a first series-coupled circuit of the charge pump to the output of the rectifier stage.

  • Patent number: 8130864
    Abstract: A system and method of beamforming may reduce feedback requirements. In some implementations, a beamforming technique may employ a diagonal matrix as a beamforming matrix along with a stream-to-transmit antenna mapping matrix. In some antenna phase beamforming strategies, a diagonal beamforming matrix in which the diagonal elements have a constant magnitude may be employed. Accordingly, a beamforming system may be utilized with few feedback information bits being transmitted from the beamformee; such a system may also minimize or eliminate power fluctuations among multiple transmit antennae.
