Title: Network security device
Inventor: NORRIS ROLAND WILLIAM
IPC: H04L29/06
Filed: 2000-02-03
Abstract: A network security device 1 has a switching circuit which prevents any physical connection being made to a protected network until a connection has been authorised by the network. A remote system wishing to gain access to the protected network dials and connects to the input section 1a of the device. The device prompts the remote system for identification. After receiving identification the processing section 1b disconnects the input section 1a thereby isolating the remote system from the device. The processing section then connects to the output section 1c, establishes a secure connection to the protected network and passes on the identification information. The processing section erases the identification information supplied and disconnects from the output section before reconnecting to the input section enabling it to accept the next request. The protected network authenticates then contacts the remote system.

Title: Economical bandpass filter arrangement for a multi-band mobile phone receiver
Inventor: PECKHAM DAVID SUTHERLAND
IPC: H04B1/40
Filed: 2000-02-18
Abstract: A multi-band receiver 102 has respective bandpass filters 306 and 304 for two closely spaced but distinct channels, e.g. 1.8 GHz DCS and 1.9 GHz PCS frequencies. A further bandpass filter 318 is coupled in series with a selected one of the filters 306 or 304, and has a passband which includes both reception bands. Sharing of the filter 318 between the two channels reduces cost and volume. The filter 318 may precede or follow the filters 306 and 304. A fourth filter 308 passes signals in a further band widely spaced from the other bands, e.g. a 900 MHz GSM band.

IPC: H04Q3/00
Filed: 2000-07-17
Abstract: In a General Packet Radio Service (GPRS), when a mobile user roams from one Serving GSM Support Node (SGSN) to another while using an Intelligent Network (IN) service, a state model of the call is transferred from a Switching State Function (SSF) in the former node to one in the new node so that dialogue with the Service Control Function (SCF) can continue. The model is the Intelligent Network Basic Call State Model (BCSM) plus Points In Call (PIC) and Detection Points. The invention allows real time applications such as video to be fully supported when a user roams from one support node to another.

Title: Vector quantisation where errors are transmitted only if there is sufficient channel capacity
Inventor: KNEE MICHAEL JAMES
IPC: H04N7/30
Filed: 2001-01-24
Abstract: In the compression of motion vector information, the components of the motion vectors are quantised, the quantised values are compressed and transmitted and the quantisation errors are additionally transmitted, whenever sufficient channel capacity is available. Typically, the motion vectors are compressed using run length coding. The motion vectors may be run length coded using a scanning pattern designed to increase the expected run lengths of quantised motion vectors. Alternatively, the motion vectors are labelled in descending order of frequency of occurrence, and then run length encoded.

Title: Demodulation apparatus for multi-carrier PSK signals which reduces inter-carier interference
Inventor: ASHTON CHRISTOPHER JAMES
IPC: H04L27/26
Filed: 2001-03-20
Abstract: The disclosed apparatus is suitable for use with continuous phase signals which have a phase transition period 9 in which the phase varies non-linearly between the phase of a previous symbol and the phase of the present symbol 10. The frequency is greater within the transition period 9 than within the data period 10. Interference between the transition period 9 of a low frequency carrier and the data period 10 of a higher frequency carrier is avoided by synchronising the symbol positions of respective carriers and performing demodulation using only the data periods 10, preferably using a FFT. The transition periods 9 are ignored and can therefore be considered guard intervals. The demodulation apparatus is also suitable for use with a combined amplitude/phase modulation scheme such as QAM.

Title: Method for modelling fluid displacement in a porous environment taking into account hysteresis effects
Inventor: EGERMANN PATRICK
IPC: G01N33/24
Filed: 2001-07-10
Abstract: The invention concerns a method comprising experimentally determining the variation curve of capillary pressure in pores on the basis of saturation with respect to liquid phases, modelling the pores of the porous environment by capillary distribution with fractal distribution while taking into account in the case of a three-phase water (wetting fluid)-oil-gas mixture for example stratification of the constituents inside the pores, with water in contact with the walls, gas in the centre and oil forming an intervening layer, determining, on the basis of said capillary pressure curve, values of fractal dimension corresponding to a series of given values of saturation relative to the liquid phase, modelling hysteresis effects modifying the mobile saturation levels of fluids actually displaced in the sample which vary in the course of drainage and imbibition cycles, modelling relative permeability levels directly in the form of analytical expressions depending on the different values of fractal dimension obtained and in accordance with the stratified distribution of the different fluids in the pores, and using a porous medium simulator to determine, on the basis of the relative permeability levels, the optimal conditions of fluid displacement in a porous medium.

Title: Valve assembly for controlling flow from a storage tank, eg in a central heating system
Inventor: BARNES SCOTT JARROD
IPC: F16K31/08
Filed: 2002-06-19
Abstract: A valve assembly suitable for controlling the flow of fluid from a fluid storage means, for example an expansion tank in a central heating system, consists of a bore having a closure member 38 movable between an open and closed position. Under normal operating conditions, the closure member 38 floats on or in fluid in the valve assembly. In the event of a sudden reduction in pressure, e.g. due to a leak in the system downstream, the closure member 38 switches to the closed position and is held in place by a non-return means, e.g. a magnet (32, Figure 2). The bore may include primary apertures 60 and auxiliary apertures 62, wherein, as the closure member 38 switches to the closed position, it moves to prevent flow through the primary apertures 60, thereby restricting the flow of fluid to the auxiliary apertures 62 (Figure 7), which causes the closure member 38 to be brought swiftly to the closed position (Figure 8).

Title: Active cooperation deadlock detection system/method in a distributed database network
Inventor: WIGER ULF T
IPC: G06F9/46
Filed: 2001-02-09
Abstract: In a network including a distributed database (e.g. replicated database) which includes data objects, a data object locking/unlocking system/method is provided where clients actively cooperate with one another during lock negotiations so that deadlock may be detected and broken. Deadlock detection (e.g. via WFG analysis) is performed on a local level by clients based in part upon messages that clients receive from one another regarding transactions being executed. For example, a first client (i.e. a process or thread working on a task and seeking to access one or more data objects) may send a message to a second client of the network indicating that the first client is holding a particular data object and waiting for another particular data object. By combining this information with facts already known to it, the second client can determine that it and the first client are involved in a deadlock. Once detected, deadlock may be resolved or broken by one of the two or more clients in the deadlock surrendering a lock on a data object.
