20120307834 | Synchronous Network Switch - A network router connects network nodes within a ring network for transferring frames of data within the network. It has a plurality of network ports which pro-vide a physical interface to the network nodes. The network router further has a routing processor which is connected to the network ports. The routing processor is configured for receiving frames and transmitting frames at the same time. It reads a specific payload section from a frame to be received and places with payload section within another specific payload section of a frame to be transmitted. | 12-06-2012 |
20100246408 | System and Method for Signal Failure Detection in a Ring Bus System - A communication system, network node, and communication port architecture are provided for transporting data across a ring network. If a network node detects a signal failure, the communication port of the network node configures itself as timing master and communicates a shutdown command to the other network nodes. In addition, the communication port sets an internal flag signaling this “signal off” event. All other network nodes, which receive the shutdown flag, do not set this internal status, and instead, save a status of “no fault saved.” Accordingly, it can be easily determined where the loss of signal occurred. | 09-30-2010 |
20090094657 | Real-Time Video Transmission System - A system for transferring real-time video data over a network comprises a video source, a video encoder for encoding and compressing video data supplied by the video source and a first network interface controller for transmitting compressed video data on the network. Furthermore a second network interface controller for receiving compressed video data from the network, a video decoder for decoding the video data received by the second network interface controller, and an image processor for processing and/or displaying the decoded video data from the video decoder are provided. The network controllers are configured for transmitting and receiving data in a continuous data stream which is synchronized with a clock signal and in a format which prescribes a pulse sequence of individual bit groups of which at least one is used for video data. | 04-09-2009 |
20090092210 | System and Method of Real Time Synchronization through a Communication System - A communication system, network, interface, and port architecture are provided for transferring data via a network. The network can be configured by connecting ports in a daisy chain arrangement to achieve a ring architecture or topology. The network transmits data according to a specific protocol. A first port transmits frames containing frame count information which is divided into several pieces, with each piece being transmitted in a single frame. A second port receives the frames, stores them in a frame buffer, and reassembles the frame count information from a plurality of frames. | 04-09-2009 |
20090080462 | System and Method for Transferring Data Packets Through a Communication System - A communication system, network, interface, and port architecture are provided for transporting data across a network. The network can be arranged by connecting the ports in a daisy chain fashion to achieve a ring architecture or topology. The network forwards data according to a specific network protocol. A first port forwards frames having a preemptive acknowledge field before the payload. A second port receives these frames, stores them in a frame buffer and modifies the preemptive acknowledge field according to its available frame buffer capacity. Said first port controls its data flow according to the modified preemptive acknowledge field. | 03-26-2009 |
