  • Patent number: 10397831
    Abstract: Systems and methods are described for load balancing between frequency bands based on bandwidth capacity. A load for a first frequency band and a load for a second frequency band may be determined, wherein a cell communicates with wireless devices over the first and second frequency bands. The determined loads may be adjusted based on a channel width for each frequency band and a duplexing scheme for each frequency band. And the adjusted loads may be balanced between the first frequency band and the second frequency band by instructing wireless devices in communication with the cell to change frequency bands used for communicating with the cell.

  • Patent number: 10237498
    Abstract: Extension devices such as upstream facing port devices (UFP devices) and downstream facing port devices (DFP devices) connect via an extension medium. When a UFP device and a DFP device pair with each other, DisplayPort video and/or audio information from a DisplayPort source device can be presented by a DisplayPort sink device, which are coupled to the UFP device and DFP device, respectively. In some embodiments, the DFP device may train a DisplayPort link to the DisplayPort sink device regardless of whether it is receiving actual data from a UFP device, and may provide placeholder data to the DisplayPort sink device in order to keep the link active. The DFP device may then replace the placeholder data with the actual data from the UFP device, once received, and may thereby seamlessly switch the DisplayPort sink device from presenting placeholder data to presenting data from the DisplayPort source device.

  • Patent number: 9832679
    Abstract: A window regulator for improving the performance of communications networks is described. In a communications network, data is sent downstream from a sender to a receiver, and acknowledgements are sent back upstream. When data is received at the receiver, the data is placed in a buffer and an acknowledgement of receipt may be sent. If no acknowledgement is received by a sender after a certain period of time, the sender retransmits the data. The receiver communicates how much data the receiver is willing to receive at any given time by sending an advertised window to the sender. The window regulator sets the size of the advertised window based on measurements of capacity in the network to improve the amount and rate of data sent downstream while avoiding loss of data and subsequent retransmissions.

    Abstract: A frequency domain method and system for online self-calibrating microphone frequency amplitude response based on noise floor (minima) tracking are disclosed. A cellular telephone or other system with dual microphones may self-calibrate itself on-the-fly. The system selects one of the microphones as a reference and calibrates the frequency response of the two microphones using the first microphone as a reference, so that they have a matched frequency amplitude response. To achieve this on-the-fly calibration, the system uses background noise for calibration purposes. The signal power spectra of the noise minima at the two microphones is used to calibrate the respective microphone frequency response. The system may then adapt the frequency amplitude responses of the two microphones so that the power spectral density from each microphone matches the other, and the system is then calibrated.

  • Patent number: 9322907
    Abstract: A method for behavior based Friend/Foe/Neutral determination is disclosed. The method receives RF communications from a plurality of perceived entities and records a plurality of first level characteristics of the RF communications. The method determines, from an analysis of the first level characteristics a plurality of second level characteristics of the RF communications. From these second level characteristics, the method determines transmission patterns of the entities over time which lead to an ultimate classification of the perceived entity as a Friend/Foe/Neutral based on the patterns.

  • Patent number: 9295048
    Abstract: A method, an apparatus, and a computer program product for wireless communication are provided. The apparatus, e.g., base station, determines a plurality of component carriers configured for a user equipment (UE) served by the apparatus. The plurality of component carriers includes a primary component carrier and a secondary component carrier. The primary component carrier may be a time division duplex (TDD) carrier having a same uplink:downlink configuration as a first cell at a neighboring base station, and the secondary component carrier may be a TDD carrier having a different uplink:downlink configuration as a second cell at the neighboring base station. The apparatus exchanges data with the UE according to an effective uplink-downlink subframe partition of the configured component carriers. The effective uplink-downlink subframe partition may be time varying and the apparatus may operate to limit interference due to the different TDD configurations at the serving and neighbor cells.

  • Patent number: 9276731
    Abstract: System, methods and apparatus are described that facilitate transmission of data, particularly between two devices within an electronic apparatus. Information is transmitted in N-phase polarity encoded symbols. Drivers may be adapted or configured to align state transitions on two or more connectors in order to minimize a transition period between consecutive symbols. The drivers may include circuits that advance or delay certain transitions. The drivers may include pre-emphasis circuits that operate to drive the state of a connector for a portion of the transition period, even when the connector is transitioned to an undriven state.

  • Patent number: 9217326
    Abstract: Systems and methods for enabling communication using two different alternative protocols on a single communication line between remote tools and control equipment used in well operations. In one embodiment, a system includes control equipment, remote tools and a communication line coupled between the control equipment and the remote tools. Each remote tool detects mode control signals on the communication line and operates alternately in either a first mode or a second mode in response to detecting corresponding mode control signals. The first mode enables two-way communication of data on the communication line according to a first communications protocol. The second mode enables one-way communication of data on the communication line from the remote equipment to the control equipment according to a second protocol. The second protocol is different from the first protocol, and may be incompatible with the first protocol.

  • Patent number: 9195626
    Abstract: A FCP initiator sends a FCP write command to a FCP target within a second FC Exchange, and the target sends one or more FC write control IUs to the initiator within a first FC Exchange to request a transfer of data associated with the write command. The first and second FC exchanges are distinct from one another. A payload of each write control IU includes an OX_ID value with which the initiator originated the second Exchange and a RX_ID value assigned by the FCP target for the second exchange. The two Exchanges yield a full-duplex communication environment between the initiator and target that enables the reduction or elimination of latencies incurred in a conventional FCP write I/O operation due to the half-duplex nature of a single FC Exchange. The write control IU may be an enhanced FCP_XFER_RDY IU or a new FC IU previously undefined by the FCP standard.

  • Patent number: 9147023
    Abstract: A method for designing a system on a target device is disclosed. A first netlist with a first set of functionally invariant boundaries (FIBs) is generated after performing extraction during synthesis of a first version of the system in a first compilation. One or more of the FIBs is invalidated from the first set after performing optimizations during synthesis in the first compilation resulting in a second netlist with a second set of FIBs. A third netlist with a third set of FIBs is generated after performing extraction during synthesis of a second version of the system having a changed portion in a second compilation. Connectivity of matching nodes from the first netlist and the third netlist reaching FIBs is traversed to identify equivalent nodes associated with identical regions. The identical region in the third netlist is replaced with an optimized synthesized region from the second netlist.
