Patent GB-2272308-A (GB)
Title: Control system employing early-off hold function
Inventor: BAUCK RANDALL C
IPC: G05B21/02
Filed: 1992-06-26
Abstract: An automatic control system (10) employing a sample and "early-off" hold function (25) is described. The invention involves implementing the hold function (23) in such a way as to reduce the amount of delay or phase lag introduced into the system (10). The reduction in phase loss permits a greater operating bandwidth, thereby enhancing performance without a corresponding increase in cost or complexity. Instead of holding a constant value for the duration of a sample period (T), the present invention holds the constant value for some fraction of the sample period (T) and then changes the output value of the hold device for the remainder of the sample period (T). <IMAGE>

Title: Method for the fabrication of a semiconductor device
Inventor: CHOI YANG KYU
IPC: H01L21/768
Filed: 1995-06-26
Abstract: A semiconductor structure which may have two levels of metal wiring 2, 6 is fabricated by forming first metal wirings (2) on a surface of the semiconductor structure using a mask. An insulating layer (4) is then formed using the same mask and is grown to have substantially the same thickness as the first metal wirings whereby a planarized surface is formed. An insulating layer (5) is then deposited on the planarized surface formed on which a second metal layer (6) is then formed. A patterning step for the second metal layer (6) can be carried out with ease because of the planarized surface (2, 4) formed, giving rise to a significant increase in the production yield. The method can be usefully applied for ultra large scale integration devices under a design rule of less than 0.4  mu m. <IMAGE>

Title: Idealised time display device to combat jet-lag
Inventor: SCHWIBINGER HANS-PETER
IPC: G04G9/00
Filed: 1995-08-22
Abstract: A device is described to minimise the affects of jet lag on journeys between time zones by displaying a non-existent idealised time at 12 which gradually changes (speeding up or slowing down normal clock time) from the local departure time to the local arrival time, thereby changing the users perspective of zonal time change gradually. The device displays messages at 2 which tell the user what to do to minimise jet-lag, eg drink coffee. The variables (local time, journey time, destination time and direction of travel) are entered by the user. The device may be incorporated into a pocket calculator, electronic note book or computer.

Patent GB-2301446-A (GB)
Title: Bistable nematic liquid crystal devices
Inventor: BRYAN-BROWN GUY PETER
IPC: G02F1/1339
Filed: 1995-01-30
Abstract: The invention provides a nematic liquid crystal device with two bistable switched states. The device comprises two cell walls carrying electrodes structures and enclosed a layer of a nematic liquid crystal material. The cell walls are treated to provide a bigrating on one or both walls. The bigrating is a shaped surface that permits liquid crystal molecules at a surface to lie in two different angular directions, e.g. 45{ or 90{ apart, in contrast with conventional surface alignments which align liquid crystal molecules in a single direction at a surface. For a cell with bigratings on both walls the two alignment direction on both walls are in register. Polarisers are arranged in front and behind the cell with their optical axes orthogonal and with the optical axis of one polariser parallel to one of the switched alignments. In this example, as the material is switched between the two alignment states the polariser transmits or blocks light. The bigratings may be symmetric or asymmetric, in which later case an amount of surface tilt is obtained. Appropriate surface tilt on both cell walls may give a splayed molecular configuration in both switched states. For splayed configurations, the device may be electrically switched using flexoelectric coupling. For other configurations the device may be switched by use of dc pulses in combination with chiral ions in the liquid crystal material. The bigratings may be produced by interferography, photolithography, embossing, ruling, or transferred from a carrier layer. A bigrating on one cell wall may be combined with a conventional monograting or e.g. rubbing alignment treatment on the other cell wall. In this case the material is twisted in both its switched states.

Title: Dual,independent sensor vehicle impact detection system
Inventor: WHITE CRAIG W
IPC: G01P15/00
Filed: 1996-06-19
Abstract: A vehicle impact detection system (10) for controlling the actuation of an occupant safety restraint device includes a dual, independent sensor arrangement (12) having a vibratory sensor (24) affixed to an outer surface (16) of the vehicle for continuously generating an output signal (14) representative of the condition of the outer surface, and a control circuit (20) for performing signal processing on the output signal (14) to predict the time at which a second crush sensor (26) will produce an output signal (18). The system (10) allows a single point outer surface sensor to reliably predict severe impacts within a few milliseconds of initial impact, and therefore is particularly suited for controlling the actuation of a safety restraint device in response to side impacts.

Title: Differential driving system
Inventor: GIBSON PETER JAMES
IPC: B62D11/14
Filed: 1996-07-05
Abstract: A differential driving system capable of operating as a steering system for skid steer vehicles having two differentials, a steering differential (11) dedicated to steering and a propulsion differential (1) having its planet carrier (2) adapted to be driven by a vehicle motor (5) and providing drive shafts (6, 7) for the opposite sides of a vehicle. One of the gears of the steering differential is driven by a variable speed reversible motor (17), which is adapted not to rotate for straight running, and the other two gears are each connected to rotate with one of the drive shafts (6, 7). No rotation of the gear of the steering differential driven by the reversible motor (17) means that the other two gears rotate in the same direction and the drive ratios of the connection means ensure that the angular velocities of the two drive shafts (6, 7) are equal.
Patent GB-2333114-A (GB)
Title: Improvements relating to height adjustable bumps for road traffic control
Inventor: HARVEY JOHN GWYN
IPC: E01F9/529
Filed: 1998-01-13
Abstract: Speed restricting bumps for installation across a road comprise a contact plate 17 that can be selectively locked in position or be deflected vertically and progressively by a passing road vehicle in relation to a base plate 18. With the contact plate locked into the raised position a passing road vehicle will experience a jolt as it traverses the device. When the contact plate is unlocked the passing vehicle will deflect vertically and progressively the contact plate due to the differential angles of the surfaces of the contact plate 17 and base plate 18. The weight of the road vehicle is either then borne by, or transferred to, the base plate 18, so that the road vehicle passes by relatively unhindered. In an alternative form the contact plate 3 is normally level with the road surface, so that the physical jolt is only imparted when the contact plate is unlocked, and can therefore be deflected vertically so that a dip for the road vehicle to drop into is formed. The locking and unlocking of the contact plate is made by a controlling mechanism whose operation is determined by a speed measuring device. There may be a number of narrow contact plates adjacent each other, or one wide contact plate.
