Title: Obstacle warning system for vehicle
Inventor: SANEYOSHI KEIJI
IPC: H04N13/239
Filed: 1993-03-18
Abstract: The scene outside a vehicle is imaged by two CCD cameras whose outputs are compared to give the range to all points in the images as in GB 2261339. The three-dimensional data thus acquired is then analysed so as to distinguish between road surfaces and other objects; road surfaces are distinguished by being substantially planar and bounded by substantially straight parallel white lines within a moderate distance range; potential obstacles lie at least 10cm above the road surface. The relative and absolute positions, velocities and accelerations of potential obstacles can be analysed to determine if a collision is likely; objects near the edge of the road can be given a low weighting. <IMAGE>

Title: Combustion chamber with fuel injectors of different types
Inventor: SANDELIS DENIS JEAN MAURICE
IPC: F23R3/34
Filed: 1993-07-14
Abstract: A combustion chamber, e.g. for a gas turbine, having a plurality of fuel injectors (5, 6) disposed in the bottom of the chamber, the injectors comprising two different groups (5, 6) suited to two different operating regimes, is characterised in that the injectors of each group (5, 6) are arranged in a zig-zag manner when looking towards the bottom of the chamber and the injectors of the two groups are interspersed with each other so that each injector (5) of one of the groups is situated radially inwards or outwards from an injector (6) of the other group. Shield walls extend from the chamber bottom to initially isolate the jet of fuel projected from one group of injectors from the other group of injectors. The shield walls may surround each of the injectors of one group only. <IMAGE>

Title: Moving underwater sediment
Inventor: HARDISTY JACK
IPC: E02B3/02
Filed: 1993-08-23
Abstract: Beaches are nourished by sensing optimum nourishment conditions in the adjacent sea and then suspending sediment to be transported by the sea to perform such nourishment. This is done by pumping water through perforate tubes 13 laid on the seabed in the sediment. Pumping is halted when it is sensed that the conditions are not such as to nourish the beach. A similar system can be used for maintaining tidal channels clear for navigation. Sound emitters rather than pumps may be used to activate sediment suspension. <IMAGE>

Title: Method and apparatus for calibrating a speedometer
Inventor: BROWN PHILIP CHARLES
IPC: G01P21/02
Filed: 1993-09-01
Abstract: Calibration apparatus for calibrating a speedometer having a magnet and operable under magnetic induction, includes a calibration bed having a driver for driving the worm of the instrument, a camera and vision system for producing a signal indicative of the position of the instrument pointer (1), a magnetiser for magnetising the magnet and a control unit.

Title: Thin-film transistors with reduced leakage
Inventor: MCGARVEY BRIAN PATRICK
IPC: H01L29/786
Filed: 1993-09-10
Abstract: In a liquid-crystal display comprising thin-film field-effect transistors (TFTs) on a substrate (10), reduction in side-wall leakage current of a TFT is achieved by giving the current path through the channel (1) extra length (L2+L3) adjacent to the side wall 13 of the TFT thin-film body (11) compared with its length (L1) in the area of the body (11) away from the side wall (13). This extra length (L2+L3) is due to an unmodulated drain-adjacent part (7) of the channel region (1) adjacent to the side wall (13). The unmodulated part (7) is substantially intrinsic and unmodulated by the gate (16) in operation of the transistor. This unmodulated part (7) spaces the drain electrode (5) laterally away from the gate electrode (16) at the area adjacent to the side wall (13) where high leakage currents may be generated. <IMAGE>

Title: Estimating grain size in geological samples
Inventor: BIRD COLIN LEONARD
IPC: G01N15/02
Filed: 1995-06-29
Abstract: A method for estimating the grain size in geological samples such as cores is achieved by a data processing system wherein data of a geological sample is retrieved from a storage device, the storage device storing data of the geological sample which incorporates least one characteristic varying with the grain size of the sample. Responsive to a selection of a portion of the data, a subset of the data corresponding to the selected portion is retrieved, the subset of data incorporating said at least one characteristic varying with the grain size. Next, a set of variations of said at least one characteristic in said subset of the data is evaluated in order to determine an estimate of the average grain size of the portion with respect to a dominant variation of said set. In preferred embodiments, a digital image of the geological sample representative of said data is displayed on a display device in order to allow a user to select the portion of the image to be evaluated. Then the determined estimate is made available to the user.

Title: A driving device having a belt which is frictionally or positively driven
Inventor: BECKER HARALD DIPL ING
IPC: B62D55/12
Filed: 1996-02-28
Abstract: A driving device, eg for earth-moving vehicles, comprises a driving pulley 3 having a ring 7, carrying catches 5, which may rotate relative to pulley 3 via, for example, semi-elliptic spring elements 4. Bolts 8 pass through a radial clearance or slots and attach the ring 7 to the spring elements 4. Catches 5 are, in the frictionally driven mode, engaged with toothing 6 on the inner side of belt 2 in an almost load free manner. When slip occurs between the belt 2 and pulley 3, the ring 7 rotates relative to the pulley 3 against the force of springs 4, thereby increasing the load transmitted by the catches 5 to the toothing 6 of the belt 2 which results in a smooth transition between the frictionally-engaged drive to a positive-locking drive. Alternatively the ring 7 may be coupled to the pulley 3 by a hydraulically operated clutch.

Title: Power Off Control in a Storage Type Radio Data Communication Terminal
Inventor: TANIGUCHI KEIICHI
IPC: H04L29/00
Filed: 1996-09-25
Abstract: In a storage type data communication terminal, a first switch section is connected to a power feeder and turned on/off by an operator. A second switch section is connected in parallel with the first switch section and turned on/off in accordance with a control signal. When the first switch section is turned off during a communication phase, the control section holds the second switch section in the ON state until reception of an acknowledgement from the distant station with respect to data transmitted immediately before the first switch section is turned off. In this way, the operator knows up to which packet transmission has been completed and can avoid retransmission of the same data.
