Title: IC engine fuel supply system
Inventor: MORIKAWA JUNYA
IPC: F02D41/00
Filed: 1994-10-14
Abstract: In an ic engine having a purge canister for storing fuel tank vapour, the quantity of fuel to be supplied to the engine is corrected in accordance with the condition of the purge piping eg to compensate for pressure losses in the piping, delays in purge flow response or ageing of the canister. A first fuel correction coefficient (FPGI1) is calculated (Figs. 14A and 16A) from canister pressure (PCN), intake pressure (PM) and atmospheric pressure (ATP). The first coefficient (FPG1) may be calculated in association with idling speed control value (Fig. 19). A second fuel correction coefficient (FPG2) is calculated (Figs. 14B and 16B) from changes in purge flow quantity (QPG) and canister pressure (PCN). The second coefficient (FPG2) may be calculated in association with an air-fuel ratio feedback control (Fig. 19B). <IMAGE>

Title: Addressing ferroelectric liquid crystal displays
Inventor: HUGHES JONATHAN RENNIE
IPC: G09G3/36
Filed: 1994-04-08
Abstract: The invention concerns a surface stabilised ferroelectric liquid crystal (SSFLC) display devices. Displays are formed by cells containing a thin layer, e.g. 2  mu m thick, of smectic liquid crystal material. The cell walls are surface treated and carry e.g. row and column electrodes forming an x, y matrix of addressable display elements or pixels. These devices can show bistability and switch between their two stable state on application of a dc pulse of appropriate polarity, amplitude and width. In this invention the device is addressed by first preconditioning the liquid crystal material at each pixel by applying one of two different levels of ac bias, thereby changing the switching characteristics of the material, and second by switching with application of a switching pulse. This results in pixels that have received the first of the ac bias levels switching whilst the other pixels do not switch. The two levels of ac bias may be applied e.g. by a combination of bipolar strobe pulses and two bipolar data waveforms applied in a multiplex addressing manner to the row and column electrodes. The subsequent switching pulse may be shared between row and column electrodes to give a resultant pulse of appropriate polarity, amplitude and width. <IMAGE>

Thus a three-dimensional surface (R) Figure 4 defined by parametric spline patch surfaces joined at surface boundaries with at least one edge (E1, E2) defining a discontinuity in said surface and with at least one vertex (V1-V3) defining a point on said edge is mapped to a flat plane by growing a regional mesh (Figure 5a) on the surface conforming to its topology independently of said boundaries, the mesh coinciding with and spanning the mathematical definition of the surface and having nodal points interconnected by links defining triangular or other polygonal elements therebetween. Said elements are mapped to a flat plane and assembled in two-dimensional shape. <IMAGE>

Title: NMR borehole gas logging
Inventor: HURLIMANN MARTIN D
IPC: G01V3/32
Filed: 1996-03-20
Abstract: The wait times and pulse spacing in a CPMG sequence may be varied. The T1 relaxation time is found and is used to determine the gas effect on formation parameters. Gas saturation and gas chemical composition can be derived. The large diffusion coefficient of gas renders the T2 relaxation time of gas sensitive to field gradients. In formations where gas occupies pores exceeding 10 microns, this T2 effect can be used to identify gas even though the tool gradients are not uniform. Measurement while drilling is mentioned.

Title: A computer security system
Inventor: KEW MICHAEL JEREMY
IPC: G06F21/35
Filed: 1995-01-12
Abstract: A method of preventing unauthorised access to a host computer system (1) by a user at a remote terminal (2) is provided using paging system technology. In the method, a user inputs his user identification code input into the terminal (2) which transmits same to the host computer system (1). The system then generates a random code (Code A) and subjects Code A to a transformation characteristic of a transformation algorithm identified by the input user identification code so as to generate a transformed code (Code B). Code A is transmitted via a paging system (7), to a receiver (6) held by the user. The receiver (6) comprises transformation means adapted to transform the received Code A to a second transformed code (Code C), and means (9) for displaying Code C to the user. The user then inputs the displayed Code C to the terminal (2) which trasmits it to the host system (1). The input Code C is then compared with Code B and access is only permitted if Code C matches Code B.

Title: Multiple suppression in geophysical data
Inventor: PHAM LONG DON
IPC: G06T15/10
Filed: 1996-09-18
Abstract: This invention is a method of attenuating multiples in seismic data, particularly three-dimensional seismic data in which seafloor roughness is present. The method relies on an efficient ray-tracing procedure to determine traveltimes for each multiple. The characteristics of the seismic data are used to estimate the waveform of the multiple to be attenuated. The traveltime and the estimated waveform are then used to attenuate the multiple from the original data. The method can be employed both for water-bottom multiples and for source (36) and receiver (26) pegleg multiples.
