20100150176 | CAN node, and communication method of communication system including CAN node - A Controller Area Network (CAN) node includes a conversion and retransmission unit which retransmits a transmit message if the transmit message carries a retransmission ID out of ID codes, by changing the ID code of the transmit message to a retransmission-specific ID corresponding to the retransmission ID, where the ID codes indicate priorities of transmit messages, the retransmission ID indicates that the transmit message is to be retransmitted, and the retransmission-specific ID is an ID code specifically for use in retransmission, and a conversion and reception unit which checks whether an original message corresponding to a retransmit message has been received successfully, the retransmit message being a receive message carrying the retransmission-specific ID, and discards the retransmit message if the original message corresponding to the retransmit message has been received successfully, but converts the ID code of the retransmit message into a retransmission ID corresponding to the retransmission-specific ID if the original message corresponding to the retransmit message has not been received successfully. | 2010-06-17 |
20100150177 | System and Method for Autonomous Combining - A user agent capable of autonomous combining. The user agent can be implemented as a processor configured to promote receiving a first signal from an access node and a second signal from a relay node. The processor may be further configured to combine the first and second signals. | 2010-06-17 |
20100150178 | Propagation delay time adjustment method, propagation delay time adjustment system, propagation delay time adjustment device, storage medium stored with propagation delay time adjustment program, and node device - There is provided a propagation delay time adjustment method for adjusting the propagation delay time occurring within a reception circuit for each channel of a center node device configuring a 1-to-N communications system in which communication is performed between the center node device and N (N being an integer of 2 or more) individual edge node devices using a Synchronous Code Division Multiplexing method, the center node device comprising a main control section, and each of the edge node devices comprising an auxiliary control section that controls the propagation delay time in cooperation with the main control section, the transmission delay time adjustment method comprising: transmission permission signal transmitting; transmission controlling; reception phase controlling; reception validity determining; optimum reception phase determining; and reception phase setting in which the main control section sets the optimum reception phase as the reception phase for the reception circuit. | 2010-06-17 |
20100150179 | REMULTIPLEXING APPARATUS - The remultiplexing apparatus comprises a control information selecting means for selecting a packet containing program control information from the inputted bit stream, a program control information editing means for editing contents of the selected program control information and generating new program control information corresponding to an outputted bit stream, and a remultiplexing means for multiplexing again the packet containing media information in the inputted bit stream and the program control information generated by the program control information editing means. | 2010-06-17 |
