  • Patent number: 11284365
    Abstract: A system for time synchronization over redundant switch-based avionics networks is disclosed. The system includes a master or source clock for determining precise UTC timing information from received satellite signals and generating time marks based on the timing information. The source clock generates network-compatible timing messages and forwards the timing messages to network switches within the switch-based avionics networks. The network switches modify the timing information to account for switch-based delays and forward the modified timing messages to destination clocks in aircraft end systems. The end systems relay timing messages back to the source clock via the network switches, the timing information again modified by the network switches according to switch-based delays, and based on the precise timing information exchanged destination clocks in end systems throughout the switched network can precisely synchronize to the source clock.

    Abstract: Methods and computer systems for establishing an interactive consistency property between receivers of messages. Messages are transmitted to receivers by a sender over a communication network including disjoint communication paths for connecting receivers and sender. Switches include local clocks. Local clocks of non-faulty switches are synchronized to each other with a maximum error (precision), and receivers detect switch failures. Redundant copies of a message are forwarded by sender to each receiver across different disjoint communication paths. A switch of each disjoint path is configured such that redundant copies are forwarded to each receiver with a temporal distance between disjoint paths. That distance is selected such that all non-faulty receivers receive redundant copies in the same receive order, when the switches and communication links of the disjoint paths exhibit no failure.

  • Patent number: 10150673
    Abstract: Techniques for supporting USB and video communication over an extension medium are provided. In some embodiments, an upstream facing port device (UFP device) is coupled to legacy connectors of a host device, and a downstream facing port device (DFP device) is coupled to a USB Type-C receptacle of the sink device that may provide both USB and DisplayPort information. The UFP device and DFP device communicate to properly configure the USB Type-C connection for use in the extension environment. In some embodiments, a source device is coupled to the UFP device via a USB Type-C connection, and legacy video and USB devices are coupled to the DFP device. The UFP device and DFP device again communicate to cause the source device to properly configure the USB Type-C connection for use in the extension environment.

  • Patent number: 10057426
    Abstract: An example method for managing a conference call includes detecting multiple concurrent audio signals. The multiple concurrent audio signals include a first audio signal from a first participant on a conference call and a second audio signal from a second participant on the conference call. The example method also includes comparing a first cumulative time period in which the first participant has spoken to a second cumulative time period in which the second participant has spoken on the conference call. The example method further includes selecting, based on the comparison, one of the first participant and the second participant as a lower ranked participant. The example method also includes providing an indication to the lower ranked participant to yield speaking in favor of another participant on the conference call.

  • Patent number: 10051205
    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: 9946325
    Abstract: A modem identifies an idle condition associated with a data network to be accessed and determines an opportunity to enter a first one of a set of low power device states based on the idle condition, where the set of low power device states further includes a second low power device state, and a host device consumes less power in the first low power device state than in the second low power device state. A notification is sent to an application processor of the host device that the modem is to enter a sleep state, where the notification identifies the first low power device state, and a low power link state is entered corresponding to the first low power device state based on a signal from the application processor. The low power link state applies to a link coupling a communications processor of the modem to the application processor.

  • Patent number: 9930090
    Abstract: A host-client protocol facilitates delivery of screen images from a host to a remote access client when the host content is continuous or large (such as high definition (HD) content). To facilitate this operation, the protocol implements several functions and operations that provide the desired result of an HD stream viewable on the remote access client. These functions and operations include one or more of: frame rate adjustment, rate control, dynamic adjustment to the stream based on client-provided screen resolution or changes, eliminating portions of the host screen that are not in view on the remote access client, implementing client-initiated zoom/pan operations on the host instead of the client, performing zoom/pan operations, dynamic control over screen updates, and (where multiple clients are receiving the stream) delivering streams to different clients at different frame rates.

  • Patent number: 9906645
    Abstract: In an embodiment, a transmitting device transmits a real-time media stream for a real-time communication session to a set of target devices. At least one of the set of target devices detects a media reception gap in the real-time communication session, and transmits a rewind request to the transmitting device to trigger the transmitting device to generate and provide a time-delayed version of the real-time media stream that includes media lost during the media reception gap. The transmitting device generates a rewind stream based on the rewind request and transmits the rewind stream to the at least one target device.
