The preferred embodiments of the present invention include an optical splitter module having connectorized pigtails that are stored on the bulkhead faceplate of the module. The module includes an optical splitter output harness, for example, a ribbon cable assembly attached to the bulkhead with rugged strain relief mechanism. The ribbon harness is converted to individual pigtails with connectors which are stored on adapter receptacles on the faceplate. Adapter receptacles used may optionally be half receptacles when storage is the only desired function or may be full receptacles when access to the pigtail ferrule tip is required. Access to the ferrule tip may be required for attaching fiber optic terminators to eliminate undesirable reflections caused by unterminated connectors. The module provides an administrative location for splitter outputs prior to being connected individually into service. The module also provides an administrative storage location for splitter outputs taken out of service as a temporary staging area before being reassigned and connected individually into service again.

A parking guidance system tracks available parking spaces and leads users to vacant spots through display boards placed at strategic locations in the parking lot. Sensor nodes are deployed at parking spaces or within traffic lanes to monitor parking space occupancy and wirelessly transmit this information. The sensor nodes form a wireless network that routes the knowledge of available spaces to the corresponding display boards and updates them in real time. Parking availability information may also be shared with users in a variety of other ways such as through the Internet, personal digital assistants, computers, mobile telephones, in-vehicle dashboards, and others.

A repeater and method provides a technique to minimize congestion and packet loss, which may be generated when a fault is detected in a ring type packet network or when the network recovers from such a fault. A repeater having a plurality of ports for transmitting and receiving packets in a ring type network for transmitting the received packets on the basis of an address included in a received packet and a transmitting port database indicating an identifier of a port to transmit the packet having the address as the destination, comprises a control packet processing block to detect reception of a fault notifying packet transmitted from a repeater having detected a fault and a control block to update, upon reception of the fault notifying packet from an immediately adjacent repeater, a port identifier of the transmitting port database having a port identifier of the port having received said fault notifying packet into a port identifier of a port connected to another immediately adjacent repeater.

A buffered distributor (i.e., a full-duplex repeater) having receive buffers for respective network ports calculates pause frames based on the size of stored data packets that need to be output by the repeater core according to a round robin sequence before congestion in an identified receive buffer is eliminated. The distribution core within the buffered distributor includes a linked list register that stores the determined links of received data packets for each network port. Upon detecting a congestion condition in one of the receive buffers for a corresponding port, the buffered distributor determines the relative position of the congested port within the round robin sequence, and calculates the pause interval based on the length of the data packets that need to be output before congestion is eliminated. The sum of the data packet lengths are compared to an output data rate of the distribution core, as well as switching delays within the core. The calculated pause frames, in conjunction with the prescribed congestion threshold, ensures that buffer sizes can be efficiently designed at a low cost, without compromising cost or risk of lost data packets.

The present invention comprises a system and method for communicating with a traffic signal by which at least one communication controller and integrated light controller are coupled by a high frequency (“HF”) coupler to a power line for transmission.

The communication link protocol used for communication between the integrated light controller and the communication controller provides a robust method for framing data within a message structure that provides byte-by-byte synchronization and message integrity through a parity check per byte, and a checksum calculation.

This invention provides a video information transmission apparatus for efficiently transmitting a digital video such as MPEG video at real time while controlling congestion on a QoS non-guaranteed IP network and suppressing degradation of a video quality. A transmission control section 13 on a sender side outputs bit rate feedback information in accordance with congestion information on the network to a real-time encoder 12, and controls a transmission bit rate to change the transmission bit rate in accordance with congestion information on the network. The bit rate feedback information is obtained based on the congestion information on the network on the sender side, or obtained on a receiver side and fed back.

A self-interference canceller (SIC) is incorporated into a transceiver to reduce or eliminate modem jamming when a transmitter in the transceiver transmits at high power levels. The SIC is configured to receive at a first input a transmitter noise reference signal including a self-interfering signal component generated by the transmitter, to receive at a second input a corrupted signal including the self-interfering signal component and a desired signal component generated by the transmitter, and to output a correction signal that resembles the self-interfering signal component. The correction signal is subtracted from the corrupted signal to generate a processed signal that is input to the modem. The SIC may be disabled when the output power of the transmitter is at a level below a predetermined threshold. The invention may be applied to a multi-radio access technology (RAT) transceiver.
