Title: Signal buffers for printed circuit boards
Inventor: BOSNYAK ROBERT J
IPC: H05K1/18
Filed: 2002-05-30
Abstract: An improved signal buffer configuration has been developed for transmitting communication signals across line traces between ICs on a printed circuit board, printed wiring board, multi-chip module, integrated circuit carrier or package, or other interconnect substrate. For example, in some realizations, multiple ICs (e.g., 102, 104) having mismatched input and output impedances are mounted on an printed circuit board and communicate with each other via line traces. A signal buffer IC is placed in-line with the connecting line trace. The buffer is sized to fit within the pitch spacing of the line trace (e.g., 202, 302, 304, 402) and contains an input impedance control circuit (e.g., 508) and an output impedance control circuit (e.g., 510). These impedance control circuits are adapted to receive a control signal to set the input and output impedances of the buffer to correspond to the impedances of the connecting line traces. In this manner, the impedances between the ICs connected by this line trace are effectively matched and transmission line errors between them are reduced.

Title: Microwave radar detection of surface discontinuities
Inventor: DUNSMORE MICHAEL ROBERT BUCHAN
IPC: B61L23/04
Filed: 2003-02-22
Abstract: Disclosed is a means for high speed investigation of the surface of a railway track 16. A millimetre wave radar system 2 is provided to transmit short pulses of millimetre wave radiation 22 towards the surface under test 16. If the surface has no flaws or defects, most of the transmitted radiation is reflected in an expected direction 24. At least one receive antenna 6,8 is provided to detect whether any transmitted radiation 22 has been scattered 28,30 from a defect 26 in the surface in a direction other than that of the expected reflection direction 24. The transmit antenna 4 may also operate as the receive antenna i.e. monostatic, however a bistatic arrangement having separate transmit and receive antennas is preferred. More than one receive antenna may be used to inspect the rail from different angles to provide increased sensitivity and to help in determining the type of defect. The polarisation properties of the scattered radiation may be used in providing information about the type of defect. A further receive antenna (38,Fig 2) may be additionally or alternatively provided in the expected reflection direction 24 to detect a drop in power of the received signal when a defect 26 occurs.

Title: Network node security analysis using mobile agents
Inventor: KALOGRIDIS GEORGIOS
IPC: G06F21/53
Filed: 2004-06-24
Abstract: The present invention relates to analysing network nodes N1, N2, N3 such as web servers using mobile software agents AA1, AA2, AA3, and network nodes for interacting with said agents. The present invention provides a system of disseminating two or more assessment agents to a target network node in an insecure network, and retrieving said agents following interaction with the node. The agents are software based mobile agents and are arranged such that they are associated with different sources (origins) or transmitters. This is achieved by forwarding the agents to a plurality of trusted nodes T1, T2, TM in the network which each modify the received agent's code e.g. source identifier/address in order to show the trusted node as the source (and final destination) of the agent, and forwarding the agent towards the target node. The system having retrieved the plurality of (further) modified agents then analyses their different interactions with the target node in order to determine a trust level for said target node. This allows the originating/source node to remain anonymous from the target node(s). One particular application disclosed is to agents being used to collect prices from a plurality of web servers/vendors.

Title: Status generation and heartbeat signalling for a node of a high-availability cluster
Inventor: POMARANSKI KEN GARY
IPC: G06F11/00
Filed: 2005-01-19
Abstract: A high-availability cluster has a number of nodes.A heartbeat signal is sent from a node through a network to the cluster. In addition a current status of the node is determined, and the status is sent out through a specialised interface to a next node. Also, a degraded status indication is sent to a next node. The heartbeat signal is sent on the network, which is used for other communications, and is not solely used for the heartbeat signal. By comparison, the status and degraded status are sent out over a specialised interface which is dedicated solely to inter-node status communication. The specialised interface couples nodes of the cluster in a ring topology.
