Title: An ignition signal monitoring system for a vehicle.
Inventor: PHILLIPS MARK IAN
IPC: B60W50/02
Filed: 2003-04-09
Abstract: An arrangement of electronic control units (ECU's) in a vehicle which are connected via a bus system for exchanging data there between. At least one of said ECU's receives the vehicle ignition signal directly and independently of the bus system. A check is conducted to whether the lack of the direct ignition signal at one such ECU is correctly indicative of the ignition being off. Derived from data available in the bus system is an additional signal representative of the ignition status. The ignition status signal is preferably derived from data such as engine RPM, wheel RPM. Preferably a CAN (central area network) bus system is used. The detection of the ignition signal is preferably required for safety, in order to initiate an emergency system shut down when a particular ignition signal detection has not occurred. This safety shut down may be required for an electrohydraulic brake (EHB) system, whereby mechanical breaking is allowed at lower decelerations.

Title: Adjustable-height structure for protection from climatic influences and changing sub-floor properties
Inventor: SCHMIDT TIMO
IPC: E04B1/35
Filed: 2003-09-15
Abstract: As a result of climatic influences, snow accumulation, drifting snow and deformations of the sub-floor, the building, operation and retreating of buildings in polar regions, especially in the Antarctic, is severely impeded and the lifetime is limited. The adjustable-height structure should avoid the existing problems as a result of its position, arrangement and operation. The building (1) forms a cover of a hall (2) which is flush with the surface of the ice and had previously been dug out from the firn sub-floor (3). The building is continuously lowered or raised by a pneumatic lifting mechanism (4) and is thus always held with its upper edge substantially at the surface of the firn. The energy required for the lifting process is stored in the form of air pressure in large overpressure storage devices.

Title: Method of secure network communication, data input via a graphical representation of a key pad and selective viewing of an area of a display
Inventor: BEESLEY RICHARD CRAIG
IPC: H04L29/08
Filed: 2004-01-29
Abstract: There is described a method of communicating over a public data network, for example the Internet. A user of a public PC, for example one located in an Internet caf’, uses the Internet browser provided on the public PC to downloaded from a remote trusted web site a secure Internet browser that then runs within the browser provided on the public PC. The user uses the secure Internet browser to browse the Internet. The secure browser has been configured so that no copy of information transmitted into the network or downloaded from the network is cached or otherwise recorded on the hard disc of the terminal. The user may thus browse the Internet without leaving a record of sensitive information (e.g. credit card details) used in the browsing session at the public terminal. Also disclosed is a method of enabling user input to a terminal via a graphical representation of a keypad and a method of selectively viewing only a portion of the display.

Patent GB-2419762-A (GB)
Title: Method of generating protected media signals by replacing data bits with hash values
Inventor: TAYLOR ANDREW ROBERT
IPC: H04L9/32
Filed: 2004-11-01
Abstract: An encoding data processing apparatus is described which is operable to generate protected compression encoded data representative of protected media signals. The apparatus comprises a data analyser which is operable to receive compression encoded data representative of the media signals and to select low perceptibility data bits in the compression encoded data which when altered would have a relatively low perceivable effect on the media signals recovered from compression decoding the compression encoded data after the selected bits had been altered. The bits are selected in accordance with predetermined criteria. The apparatus also comprises an information validation engine which is operable to form a normalised version of the compression encoded data by setting the selected data bits in the compression encoded data to a predetermined value and to generate a secure hash value of the normalised version of the compression encoded data. The information validation engine then forms the protected compression encoded data by replacing the selected data bits of the normalised compression encoded data with the data bits of the secure hash value. By generating a secure hash of the normalised bitstream rather than the original bitstream, subsequent authentication of the bitstream to verify that the bitstream has not been changed becomes possible without increasing the size of the bitstream.

Title: Fibre bragg temperature sensors
Inventor: POWELL BRIAN DAVID
IPC: G08B17/00
Filed: 2005-09-09
Abstract: A fire detection system for monitoring a volume 2 containing fluid, typically air, for the presence of smoke particles is disclosed. A conduit 3 for receiving the fluid, and any smoke particles therein, and directing the fluid to a smoke detector 1 has a plurality of inlets 6A,6B formed therein. A respective temperature sensor 17,19 is associated with each of the inlets 6A,6B which generate a signal indicative of a change in temperature in the region of the inlet. In the embodiments, the temperature sensor comprises one or more fibre Bragg gratings. The fibre Bragg gratings preferably have different grating periods. The reflected light from each fibre Bragg grating is returned back down the fibre optic cable 11 and redirected via a 2x1 coupler 51 to a wavelength detection system 53 and a personal computer 63. The combination of wavelength detection system 53 and personal computer 63 allow analysis of the reflected light patterns, as well as providing a user interface which enables detection of the occurrence of a spatial and/or a temperature variation. The location of the said variation along the fibre optic cable 11 is advantageously detectable. The system described is highly sensitive to smoke, but can advantageously also provide an indication of the location of the smoke source, because any variation in temperature at any one of the smoke inlets is also detected, the location of the sensor being known.

Title: Provision of personal data in a data communications network
Inventor: REID LUKE MICHAEL
IPC: H04L29/06
Filed: 2006-05-16
Abstract: This invention relates to the provision of personal data in a data communications network. When personal data becomes available to a user, the user can be notified via a peer-to-peer overlay network using a relatively low-security protocol. A relatively high-security client-server protocol connection separate to the peer-to-peer overlay network can then be established in order to allow the user to download the personal information. The invention has the advantage that sensitive information need not be sent when notifying the user of the availability of personal data, thus enabling a low-security protocol to be used in the notification, whilst using a high-security protocol for the download of the personal data, which high-security protocol may not be available for use via the peer-to-peer overlay network. Use of the invention also avoids the expense of high-security connections when they are not necessary and thus helps to reduce network load.

Title: Lattice pump and engine
Inventor: WAIN DAVID HOSTETTLER
IPC: F01C1/28
Filed: 2006-05-25
Abstract: The pump comprises a lattice, e.g. a square, of identical rotors, each 90 degrees out of phase with its neighbours and arranged to such that a rotor tip touches a flank of its neighbour to form fluid pockets between adjacent rotors. Each rotor is broadly lenicular or elliptical as if two quarter circle segments were arranged back-to-back. The rotors may be twisted along their length and the rate of twist may be varied. The working fluid may be a fuel and oxidiser which may be compressed, ignited and expanded to form an engine. Synchronising gears may be used but if the working fluid is sufficiently lubricating and the twist sufficiently great, the rotors may self synchronise with no external gears required. The rotors may be formed to a Z shape.
