Method of synchronizing between three or more devices
Hitherto synchronization of a number of devices has involved a large number of comparison steps between actual data or changes in data. Such comparison has potentially involved extensive redundant comparison steps. Another problem with existing synchronization methods is that such synchronization has been effected based upon the systems clocks defined by the devices. Those system clocks can be modified either intentionally or malevolently with disastrous consequences for subsequent synchronization of the devices. Accordingly, the present invention relates to a method of synchronization between three or more devices, the method involves: storing an indication of the device or devices involved in each synchronization event; storing data changes received during a current synchronization event together with the device submitting those changes; and applying the data changes subsequent to the stored synchronization event for the or each device. |

Packet communication device, packet communication system, packet communication system, packet communication module, data processor, and data transfer system
A transmit packet generated by a CPU 1 is held in a buffer 100a (100b). From among packets received from Ethernet 820a (820b), a packet, a destination of which is a communication device 800, is held in the buffer 100a (100b). A packet which should be transmitted is transmitted from a transfer judging circuit 200 to Ethernet 820a or 820b through a MAC unit 300a or 300b. If a transfer judging circuit 200 judges a packet from the Ethernet 820a to be a packet, a destination of which is another communication device, with reference to a destination MAC address, this packet is transferred to the Ethernet 820b through MAC 300b. If a usage rate of a transferring FIFO buffer 130a (130b) exceeds a threshold value in the process of transmitting a packet held in a transmitting FIFO buffer 120a (130b) on a priority basis, the priority order of a transfer packet is made higher than that of a transmit packet so that the transfer packet is transferred to the Ethernet 820a or 820b in preference to the transmit packet. This prevents a transfer buffer means from overflowing. |

Further compression of data allowing economical storage of data for extended periods of time in high-speed access memory is performed in reduced time by performing further compression during transcoding in the transform domain and without restoring image data to its original image data form.

The range can be restored by computation or estimation of an altered quantization table which is stored with the further compressed quantization values. Further advantages accrue from use of JPEG packed format for the data during transcoding. |

In one embodiment, a receiver has an equalizer, a tap-averaging block, a delay buffer, and a filter.

Adaptive GDFE
Adaptive generalized decision feedback equalization (GDFE) allows variations in one or more channels and noise of a multi-line/multi-channel communication system to be tracked. Such tracking can be used in vector upstream (one-sided) situations in communication systems such as ADSL and VDSL, among others. The GDFE may be separated into adaptive and static portions and/or components. Either a feedforward section or a feedback section (or both) can be separated to create a static component and an adaptive component. The adaptive components adjust to the instantaneous channel and noise changes (for example, using the instantaneous errors and simple LMS algorithms). When the channel and noise do not exhibit any time-variation, the adaptive filters can zero themselves. Local updating of adaptive feedforward and/or feedback filters addresses rapid changes to the spatial correlation of noise and/or changes to the multi-line channel (for example, time-variation due to temperature changes, component variations, mechanical stress, and other reasons), without disruption to separate static feedforward and/or feedback filters supplied by a controller, such as a DSL optimizer or the like that can assist by doing the heavier calculations and providing vectoring information and data to the DSL line components. An efficient implementation is provided of any triangularization of the binder channel that characterizes multi-user vectored-DMT DSL. Adaptation also allows correction of any inaccuracy in initially or previously reported crosstalk transfer functions and noise spatial correlation. |

Swarm location service for mobile ad hoc network communications
A Swarm Autonomous Routing Algorithm (SARA) is performed by simple communication node devices for node to node communications in a network, especially a Mobile Ad hoc NETwork (MANET). Each node maintains a table of pheromone values for known neighbor nodes. Pheromone values are dynamic for adapting to a dynamic arrangement of nodes, and are updated either passively or actively. Routing tables are not used. When a node receives a packet, it uses the pheromone table to simply determine whether or not to forward (rebroadcast) the packet to a neighbor node, and if possible, determines and indicates the best neighbor node for next forwarding the packet. Destination Zone Routing (DZR) and Swarm Location Service (SLS) are alternative enhancements of SARA that can be used for more efficient routing when nodes are location aware/knowledgeable. SLS may also be used to improve routing algorithms other than SARA. |

Beam guiding magnet for deflecting a particle beam
A beam guiding magnet includes a first and second coil system, which are designed such that the dipole moments of the first and second coil systems point in opposite directions. Since the dipole moments of the first and second coil systems point in opposite directions, the two dipole moments at least partially compensate for one another. The resultant dipole moment of the beam guiding magnet may be reduced. The beam guiding magnet may take into account that the remote field of a beam guiding magnet can be lowered by a reduction in the dipole moment of the beam guiding magnet. The dipole moment decreases with the cube of the distance from the beam guiding magnet. A quadruple moment, which on attenuation of the dipole moment represents the next strongest field component, decreases with the fifth power of that distance. |
