Title: Modelling fluid flows in a multilayer porous medium
Inventor: BASQUET REMY
IPC: E21B49/00
Filed: 2003-03-18
Abstract: Method for modelling low or high compressibility fluid flows in a multilayer porous medium crossed by a network of fractures of given geometry, unevenly distributed in the medium, some of the fractures communicating with one another wherein each fractured layer is discretized by means of a grid pattern comprising fracture grid cells centred on nodes either at the fracture intersections or at the fracture ends, each node being associated with a matrix block including all the points closer thereto than to neighbouring nodes, and the local flows between each fracture grid cell and the associated matrix volume are calculated in a pseudosteady state. A modelling equation whose form is similar to the diffusion equation solved in conventional cases (low compressibility fluids) allows to take account of the compressibility of the fluids. The direct flows between the fracture grid cells and the direct flows between the matrix volumes through the common edges of the grid cells are determined, and the interactions between the pressure and flow rate variations that can be observed in at least one well through the medium are simulated. The turbulent effects that appear locally around the well for high velocities of flow are represented by a term which is a function of the flow rate imposed, which modifies the form of the fracture-well and matrix-well transmissivities. Application: simulation of the response of a production well to an imposed flow rate variation for example.

Title: Ice protection system
Inventor: LINTON ALAN
IPC: B64D15/04
Filed: 2003-05-21
Abstract: An aircraft engine nacelle nose cowl (32) has a supply duct to deliver pressurised hot gas into an internal compartment (34) of the nose cowl (32). A slot (46) is provided in the nose cowl (32) to enable pressurised hot gas to pass out of the compartment (34) through the slot (46). As the pressurised hot gas passes out of the compartment (34) through the slot (46), this causes a film of water on an outer surface of the nose cowl (32) to detach from the nose cowl (32). The slot (46) is of restricted dimensions which causes localised heating of the nose cowl (32) around the slot (46) as the pressurised hot gas pass out of the compartment (34) through the slot (46). In this manner ice is prevented from accumulating on the outer surface of the nose cowl (32) and/or ice is removed from the outer surface of the nose cowl (32).

Title: Multi-user detection, decoding and remodulating method and apparatus
Inventor: GRANT ALEXANDER
IPC: H04B1/707
Filed: 2003-06-16
Abstract: In a multi-user detection receiver, a multi-user detector DET receives a signal from a multiple access channel MA and the current soft estimates of each user's contribution to the received signal, and outputs updated soft estimates for each user by subtracting the current soft estimates of all the interfering users. The updated soft estimates are soft demodulated by soft demodulators DEM1 ... DEMK, decoded by soft decoders DEC1 ...DECK which refine the probabilities of the coded bits derived from the soft demodulators DEM1... DEMK by taking into account the knowledge of the code, and output to soft modulators M1 ... MK. For each iteration of the MUD receiver algorithm, an acquisition function ACQ acquires the timing of the estimates of each user's contribution to the channel for use by the detector DET in the next iteration, giving improved acquisition performance over conventional single-user techniques.

Title: Video apparatus with display authorisation determination
Inventor: CHO EUN-SEOP
IPC: G06F21/10
Filed: 2003-08-29
Abstract: In a broadcasting signal output apparatus and a method, an OSD processing unit produces a display-lock message if a display of contents is not permitted. A control unit determines whether the decoded video signal includes a copy protection signal for preventing the video signal from being reproduced, and if so, the control unit requests and receives a certification signal from the display device to determine whether the video signal can be transmitted to the display device through the video output terminal. The control unit then determines whether the certification signal corresponds with the reproduction preventing signal, and if it does not, prevents the decoded video and audio signal from being outputted, and controls the OSD processing unit so that the display-lock message is output to the display device (e.g., screen), so that the user knows when the currently received broadcasting signal is not displayed due to copy protection signal.
