Abstract: A switch, switched architecture and process for transferring data through an FCAL switch is disclosed. The switch uses multiple switch control circuits each coupled to one FCAL network and all connected to a crossbar switch. The switch control circuits are coupled together by a protocol bus for coordination purposes. Local conversations can occur on each FCAL loop and crossing conversations through the switch can occur concurrently. The OPN primitive us used to establish the connection before any data is transferred thereby eliminating the need for buffer memory in the switch control circuits. The destination address of each OPN is used to address a lookup table in each switch control circuit to determine if the destination node is local. If not, the destination is looked up and a connection request made on the protocol bus. If the remote port is not busy, it sends a reply which causes both ports to establish a data path through the backplane crossbar switch.

Abstract: A method and apparatus for generating a performance indicator in a high-speed communication system. A plurality of disparate communication status signals with differing formats from a transceiver are combined in a logic module to create a single link quality indicator signal. The link quality indicator signal is used to encode different operational states of the transceiver from fully operational, to marginally operational, to failed. The link quality indicator signal is advantageously employed to drive a LED creating a visual performance indicator.

Abstract: Various methods and systems are provided for reduction of I-pulsing artifacts. In one example, among others, a method includes modifying at least a portion of a picture to be encoded as an I picture based at least in part upon a picture that precedes the picture. The modification can reduce an I-pulsing artifact associated with the I picture. The modified picture is intra-coded for inclusion in a series of encoded pictures, which may then be transmitted. In another example, an encoder includes adaptive pre-processing circuitry configured to modify at least a portion of a first picture based at least in part upon a second picture that precedes the first picture in a series of video pictures. For example, the modification may be based upon coding noise associated with the preceding picture. Intra-encoding processing circuitry is configured to encode the modified picture as an I picture.

Abstract: Aspects of a device, system, and method for subset determination and processing are described. In certain aspects, a process for subset determination includes determining a reference for correlation with at least one image and identifying a set of images for comparison with the reference. The reference for correlation may be specified by a user based on a desire to determine a subset of certain images from a larger group. The process further includes determining a subset of the set of images based on a correlation between the reference and the set of images. According to various features, a subset of images that not only includes certain images but also excludes certain images may be determined quickly.

Abstract: A system, method and computer program product is provided for mitigating the effects of burst noise on packets transmitted in a communications system. A transmitting device applies an outer code, which may include, for example, a block code, an exclusive OR (XOR) code, or a repetition code, to one or more packets prior to adaptation of the packets for transmission over the physical (PHY) layer of the communications system, wherein the PHY layer adaptation may include FEC encoding of individual packets. The outer coded packets are then separately transmitted over a channel of the communications system. A receiving device receives the outer coded packets, performs PHY level demodulation and optional FEC decoding of the packets, and then applies outer code decoding to the outer coded packets in order to restore packets that were erased during transmission due to burst noise or other impairments on the channel.

Abstract: A Wi-Fi Direct Group Owner stores network parameters needed for proper operation of a peer-to-peer network. These include the network name and identifier, the power save schedule, the security settings, MAC address of all of the group members, etc. To reduce the need for a single Group Owner, this information is distributed. As each new device is added to the network, all of these parameters are passed via IEEE 802.11 data packets from the device acting as the Group Owner to the new peer device. This way, the new peer device has all of the information about the group at the time that it joins. Any device in the Resilient Peer Network can temporarily take on the role of a traditional Wi-Fi Direct Group Owner (admission control). Selection of which peer will act as a Group Owner will depend on a user action or network event.

Abstract: Apparatus, a method and a non-transitory computer-readable storage medium including a set of computer-readable instructions stored thereon, which when executed by a processor causes performance of operations, including periodically measure a received signal strength indication of a broadcast control channel received from a current serving cell to detect a presence of a co-channel broadcast control channel interference. In response to determining the presence of the co-channel broadcast control channel interference, a synchronization channel re-read based upon one or more co-channel interference criteria is initiated. The synchronization channel re-read is adapted to determine if one or more neighbouring cells that are broadcasting on the same frequency as the broadcast control channel frequency of the current serving cell would be better than the current serving cell.

Abstract: An interference tolerant capacitive touch sensor readout circuit having improved power and area efficiency is disclosed. Interference rejection for the capacitive touch sensing system is realized by transferring charge between a capacitive touch sensor and the readout circuit at frequencies outside bands where a level of interference is unacceptable. Improved power and area efficient come from the simplicity of the readout circuit which comprises a switched-capacitor integrator, a comparator, a digital accumulator and number of switches for driving a touch sensor and a capacitive feedback loop. The readout circuit is capable of interfacing with both self and mutual capacitance sensor to achieve compatibility with a larger collection of sensors and provides additional sensing and diagnostic functionalities.

According to certain aspects, overlapping channel conditions can be avoided while maintaining acceptable communications data throughput.

Abstract: An analog-to-digital converter (ADC) includes reference charge cancellation features to at least partially offset a voltage distortion on a bypass capacitor of a reference buffer due to a voltage reference hit taken by a switched capacitor bank with which the bypass capacitor is connected. The charge cancellation may be configured in logic to be input signal dependent because different resolved bits or transitions between resolved bits may cause different amounts of voltage reference hits. By adjusting the bypass capacitor in response to each of at least some of the reference hits while resolving a word of bits, the reference voltage signal provided by the bypass capacitor undergoes far less settling, remaining more stable and linear for a more accurate reference voltage. Furthermore, a smaller capacitor may be used for the bypass capacitor, reducing power consumption and area on chip.

Abstract: A system and method for using energy-efficient Ethernet to control energy efficiency in lower layers. In one example, an energy-efficiency control policy in a first Ethernet device can be configured to determine a need for transitioning of at least a part of the first Ethernet device into an energy saving sate. Based on such a determination, an energy-efficiency control signal can be transmitted from the first Ethernet device to a first non-Ethernet device. The receipt of the energy-efficiency control signal by the first non-Ethernet device is used to initiate a transition by the first non-Ethernet device into an energy saving state, which in turn may initiate a transition by downstream non-Ethernet devices into an energy saving state. This process creates a single unified energy-efficiency policy domain.
