Abstract: An integrated navigation and collision avoidance system for a source object may include a navigation module and a collision avoidance module. The collision avoidance module may identify an external object that could possibly collide with the source object. The collision avoidance module may determine a likelihood of collision with the external object based on navigation information received from the navigation module. The navigation module may receive information pertaining to the likelihood of collision determination from the collision avoidance module and determine whether to include collision avoidance information and/or modify navigation instructions to generate a navigation output.

Abstract: A network communication system includes a talker that may communicate a data stream having an optimal presentation time to a plurality of listeners over a network, such as an Ethernet Audio/Video Bridging network. The optimal presentation time may be determined by a maximum latency among a plurality of latencies for connections between the talker and the listeners. A controller may communicate with the listeners to determine the maximum latency. The controller may also provide the maximum latency to the talker and the listeners. The talker may determine the optimal presentation time based on the maximum latency. The listeners may allocate an optimum amount of resources to buffer the data stream before the data in the data stream is presented.

Abstract: A network communication system includes a network address management and functional object discovery system. The network address management and functional object discovery system includes a network manager that manages network addresses for functional objects of electronic devices that communicate with each other over a network. The network manager may maintain a database that maps or associates unique IDs of the functional objects with associated network addresses. The network manager may provide non-conflicting instance IDs and network addresses to the electronic devices. The network manager may also provide instance IDs and/or network addresses for other electronic devices so that the electronic devices may communicate with each other over the network.

Abstract: A listener system, or listener, may be used with an Ethernet Audio-Video Bridging (“AVB”) network. The listener may include various components, such as an upper layer application and a stream reservation protocol stack. The upper layer application and stream reservation protocol stack may be in communication with each other. The stream reservation protocol stack may receive stream advertisements on or across the Ethernet AVB network. The stream reservation protocol stack may operate in a sparse mode and may operate in a full mode. When operating in a sparse mode, the stream reservation protocol stack may transmit one subset of the received stream advertisements to the upper layer application, and may not transmit another subset of the received stream advertisements to the upper layer application.

Abstract: A system that includes a talker, a listener, and a controller may communicate over an Ethernet Audio/Video Bridging network. The controller may communicate control messages to manage data streams between the talker and the listener through one or more application layer interfaces of the talker and the listener. Based on the control messages, the talker and the listener may communicate using a Stream Reservation Protocol to reserve connection for, or remove connection from, the data streams. The talker and listener may communicate the success of reserving or removing the connections to the controller through the application layer interfaces.

Abstract: A system that includes a transmitting apparatus and a receiving apparatus may communicate over an Ethernet Audio/Video Bridging network. The transmitting apparatus and the receiving apparatus may each include an application layer module in communication with an application interface module. The application layer module of the transmitting apparatus may interface with the application interface module to send a control message over the network to control flow of a data stream over the network. The application layer module of the receiving apparatus may interface with the application to interface module to receive the control message.

Abstract: A network media adapter includes peripheral interfaces for connection to connectors of audio/video (“A/V”) sources and sinks to respectively receive media data from the A/V sources and to transmit media data to the A/V sinks. Components are configured to syntonize or synchronize local media clocks of the A/V sources and sinks to ensure media data integrity affiliated with a protocol of a media network over which the media data is transported. A quality of service (QoS)-compliant media interface is integrated in the network media adapter through which to send and receive processed A/V media data to and from the media network according to the protocol. Other components may be configured to process, encapsulate, and transport over the media network the media data received from the A/V sources. Still other components may be configured to receive media data from the media network and decapsulate, process, and transmit the media data through one or more peripheral interfaces connected to the A/V sinks.

Abstract: A ring based network includes a first circuit and a second circuit. The first circuit selects one of a number of inputs and switches an input to a first common communication line. A second circuit selects one of a second number of inputs and switches a second input to a second common communication line linked to one of the first number of inputs. A detect circuit controls the switches of the first and second circuit to emulate a communication ring in which nodes are connected in series in a communication loop.
