20100105319 | Redriver with Output Receiver Detection that Mirrors Detected Termination on Output to Input - A redriver chip is inserted between a transmitter chip and a receiver chip and re-drives differential signals from the transmitter chip to the receiver chip. The redriver chip has switched output termination that switches to a high value to detect far-end termination at the receiver chip, and to a low value for signaling. An output detector detects when the receiver chip has termination to ground and enables switched input termination to provide termination to ground on the lines back to the transmitter chip so that the far-end termination on the receiver chip is mirrored back to the transmitter chip, hiding the redriver chip. An input signal detector detects when the transmitter chip begins signaling and enables an equalizer, limiter, pre-driver, and output stage to re-drive the signals to the receiver chip. The input signal detector also causes the switched output termination to switch to the low value termination for signaling. | 04-29-2010 |

20110105017 | RELAY DEVICE, COMMUNICATION SYSTEM AND COMMUNICATION METHOD - The relay devices store data received from an ECU connected to each of the relay devices in the first reception buffers, respectively. During a synchronizing period, the relay devices perform transmission and reception by mainline frames including attribute value groups mutually received from the ECUs. Data read out from the databases are transmitted to the ECUs. The databases are synchronized with one another only when the relay device receives the final frame from the relay device which received all the mainline frames and issues COMMIT. | 05-05-2011 |
20110117835 | METHOD FOR INTERRUPTING VOICE TRANSMISSIONS WITHIN A MULTI SITE COMMUNICATION SYSTEM - A method for interrupting voice transmissions within a multi site communication system includes operating a repeater to engage in an interruptible voice communication; to identify an open burst location based on a repeat delay when the interruptible voice communication is sourced directly via a wireless network, and to identify the open burst location as irrelevant when the interruptible voice communication is indirectly sourced via a wireless network; and repeat the interruptible voice communication including the open burst location. | 05-19-2011 |
20110159808 | ACTIVE ANTENNA ARRAY AND METHOD FOR RELAYING FIRST AND SECOND PROTOCOL RADIO SIGNALS IN A MOBILE COMMUNICATIONS NETWORK - The present disclosure teaches an active antenna array for a mobile communications network. The active antenna array comprises a plurality of antenna elements, at least one first splitter, at least one amplifier and at least one first coupler. The first splitter forwards at least one of at least one individual first protocol receive signal and at least one individual second protocol receive signal in a receive direction from an individual one of the plurality of antenna elements. The at least one amplifier amplifies at least one of the individual first protocol receive signal and the individual second protocol receive signal. The at least one first coupler is located in the receive direction downstream of the at least one amplifier and is adapted to forward the at least one individual second protocol receive signal to a second protocol receiver. | 06-30-2011 |
20110195660 | Radio repeating system, radio repeating apparatus, radio terminal operating method and radio repeating method - A radio repeating system has first and second radio terminals, a radio repeater to receive a signal transmitted from the first radio terminal and transmit the signal to the second radio terminal, and a controller to control the radio repeater. The controller has a terminal signal determiner to detect a signal from the first radio terminal to determine whether the first radio terminal is in a transmission halt mode or a transmission mode, a first counter to start counting when a result of detection is the transmission halt mode, and a second counter to start counting when a result of detection is the transmission mode. The controller halts a wireless relay operation of the radio repeater when the result of detection is the transmission halt mode while the second timer is operating, or when the first timer finishes counting. | 08-11-2011 |
