  • Patent number: 9351010
    Abstract: Transcoding multiple media elements for independent wireless delivery. Respective media or multimedia elements are selectively and respectively encoded and/or transcoded. Such respective and selective processing of different media elements provides for their unbundled and independent communication to one or more other devices. In one instance, different respective overlays of a display (e.g., a computer, TV, PDA display, etc.) are respectively and selectively transcoded and/or encoded to generate different respective streams that may each be handled differently as a function of any number of parameters (e.g., media element type, content, communication channel characteristic, source proximity, priority, etc.). Different types of media elements include photo/image, video, graphics, text, audio, picture-in-picture, two-dimensional (2D), three-dimensional (3D), and/or other types of media elements as may be included within a given configuration of a display.

  • Patent number: 9344377
    Abstract: A method to process a packet is described herein. The method comprises receiving a packet including a header and a payload. The header is parsed using a packet processor to determine type and priority of the packet. The header is then processed using a hardware acceleration block based on one or more of incoming bandwidth, priority and type of the packet. The custom hardware acceleration block generates header modification data that is sent to the packet processor. The header is modified using the packet processor, based on the header modification data, to generate a modified header. The modified header is appended to the payload and transmitted.

  • Patent number: 9344167
    Abstract: Embodiments provide approaches for sub-sampling a two-component precoder codebook to reduce the overhead associated with signaling the codebook in periodic Channel State Information (CSI) reports from a user equipment (UE) to a base station. In one embodiment, a first component of the codebook is sub-sampled to accommodate a payload capacity of a Physical Uplink Control Channel (PUCCH) CSI Report of Type 1. In another embodiment, both the first component and the second component of the codebook are sub-sampled to accommodate a maximum payload capacity associated with a PUCCH CSI report.

  • Patent number: 9345040
    Abstract: A technique for securing transmit opening helps enhance the operation of a station that employs the technique. The technique may facilitate low latency response to a protocol data requester, for instance. In one aspect, the technique provides a way for the protocol data responder to hold its transmit opening to transmit the protocol response data to the protocol data requester. The technique may allow the protocol data responder to hold the transmit opening until the protocol response data is ready and available for the protocol data responder to send.

  • Patent number: 9344098
    Abstract: The present disclosure is directed to a system and method for generating an output oscillating signal using an input oscillating signal that is subject to missing pulses and/or distortions. The output oscillating signal can be generated at a desired frequency by a frequency-locked loop (FLL) that uses the input oscillating signal as a reference clock. Because the input oscillating signal is used as a reference clock, missing pulses and/or distortions in the input oscillating signal can adversely affect the continued, stable generation of the output oscillating signal. To this end, the system and method of the present disclosure use an input oscillating signal error detector to open the FLL upon detecting a missing pulse in the input oscillating signal and/or a distortion in the input oscillating signal.

  • Patent number: 9344178
    Abstract: A method of aiding uplink transmission is disclosed. One method includes a base station downlink transmitting signals to at least a first terminal, the transmitted signals directed and conveying data to at least the first terminal. The method further includes a second terminal eavesdropping the transmitted signals, and measuring a signal quality. The second terminal estimates uplink channel information based on the measured signal quality, for aiding uplink transmission. Based at least in part on the estimated transmission channel, the second terminal transmits uplink signals to the base station.

  • Patent number: 9344268
    Abstract: A phase alignment architecture enhances the performance of communication systems. The architecture aligns a divided clock (e.g., in differential Inphase (I) and Quadrature (Q)) to a main clock, even at extremely high speeds, where skew variations of the divided clock are comparable to the main clock period. The improvement in phase alignment facilitates ultra high-speed communications.

  • Patent number: 9344046
    Abstract: Methods, systems, and apparatuses for detecting and suppressing analog error in an output stage of a digital class-D amplifier are described. In embodiments, the digital class-D amplifier includes a PWM stage, an output stage, and a feedback circuit. The PWM stage receives the signal difference between an input digital signal and a feedback digital signal, generates a digital pulse-width modulated (PWM) signal based thereon, and provides the digital PWM signal as a first component of the digital feedback signal. The output stage receives the digital PWM signal and generates an analog output signal for driving a load responsive to the digital PWM signal. The feedback circuit combines an analog representation of the PWM signal and the analog output signal to generate a second component of the digital feedback signal.

  • Patent number: 9344372
    Abstract: An interface device includes a first connector to connect to a port of a switch, where the switch sends data packets at a first rate and a second connector to connect to a port of a device, where the device sends data packets at a second rate slower than the first rate. A physical control layer connects to the first connector and the second connector to control a flow of data packets. The physical control layer throttles down the flow of data packets to the second connector when the data packets are travelling from the first connector to the second connector, and matches a speeds of the flow of data packets to the first connector when the data packets are travelling from the second connector to the first connector.

  • Patent number: 9344535
    Abstract: A method for multiple protocol wireless communications begins by determining protocols of wireless communication devices within a proximal region. The method then continues by determining whether the protocols of the wireless communication devices within the proximal region are of a like protocol. The method continues by, when the protocols of the wireless communication devices within the proximal region are not of a like protocol, selecting a protocol of the protocols of the wireless communication devices within the proximal region based on a protocol ordering to produce a selected protocol. The method continues by utilizing the selected protocol by the wireless communication devices within the proximal region to set up a wireless communication within the proximal region.
