Title: Descreening binary image data prior to image processing
Inventor: SUGIURA SUSUMU
IPC: H04N1/407
Filed: 1990-06-20
Abstract: Binary image data 201, 202, 203 to be processed (here colour masking) is first converted to multi-level data (descreened) by summing 207 the number of "1s" in a predetermined area. Processing 209 is carried out on the multi-level data. The processed data is then rescreened 210 to 214, taking into account the original disposition of "1s" in the area. Rounding errors 215, 216, 217 may be diffused into surrounding areas using feedback and may be added in at the descreening process 204, 205, 206. The image processing may be gamma correction. <IMAGE>

Title: Method of guiding driving of golf cart
Inventor: KOSEKI MASAMORI
IPC: A63B55/60
Filed: 1993-07-26
Abstract: On the basis of a driving guiding method which steers a cart (4), when one of marker lines (2) is detected, to the side of another marker line (2) among a plurality of marker lines (2), the method of the invention prevents the driving of the cart (4) from concentrating on the line (2) on the external side when the marker lines (2) are curved. A plurality of lines (1) to be detected, which are extended linearly, are laid down between the marker lines (2) in such a fashion that these lines (1) are in parallel with one another but cross the marker lines (2) on their extension. When the cart (4) equipped with means for detecting the to-be-detected lines (1) moves straight and crosses the to-be-detected lines (1), an angle of entrance of the cart (4) to the to-be-detected lines is calculated when the detection means detects two or more to-be-detected lines (1), and a steering angle is controlled in accordance with the entrance angle so calculated so that an angle of advance to the parallel lines of the to-be-detected lines (1) is always kept at a constant value. <IMAGE>

Title: Ferroelectric liquid crystal display device
Inventor: HUGHES JONATHAN RENNIE
IPC: G02F1/133
Filed: 1992-12-21
Abstract: The invention provides a surface, or electric field, stabilised ferroelectric liquid crystal (SSFLC) device with an improved contrast ratio between its two switched states. The device comprises a liquid crystal cell formed by a thin layer (7), typically 1 to 5  mu m thick, of a smectic liquid crystal material, e.g. a smectic c, held between two glass walls (2, 3) coated on their inner faces with electrodes (5, 6). Polarisers (8, 9) are arranged on either side of the walls (2,3). The device is switched between two bistable states by application of unidirectional voltage pulses, with or without the simultaneous application of ac bias voltages. To obtain optimum contrast ratio CR, the optical axes of the polarisers are rotated away from a crossed, or orthogonal position, e.g. by +/-20 DEG , and the cell rotated between the polarisers (8, 9); the precise optimum rotation depends upon material, and ac bias voltage. <IMAGE>

Title: Membrane type passive restraint for vehicle occupant
Inventor: SEKI KAZUHIRO
IPC: B60R21/215
Filed: 1994-06-10
Abstract: A shock absorbing membrane 1 is accommodated in a folded state within casing 6 mounted on a roof rail 5. Membrane 1 is held stationarily at its front and rear ends to a vehicle body by fixing pins 8, 9. A movable pin 10 mounted at a lower end of the membrane is connected through a wire 26 to a developing or unfolding means 14 mounted to a centre pillar 13. The developing or unfolding means 14 includes a gas generator 18 and a cylinder 22 with a piston slidably received therein and coupled to the wire 26. When the gas generator is operated upon collision of the vehicle to force the piston downwardly, pin 10 is pulled down by wire 26, so that the membrane is drawn out of the casing 6 and developed into a triangular shape. Thus, the membrane requires little storage space and can easily be mounted in a narrow space in the vehicle body. A small air bag may replace the piston and cylinder arrangement (fig. 10), or form part of the membrane (fig. 11). Alternatively, an air bag may be used instead of a membrane (fig. 12). <IMAGE>

Title: Remotely-operated self-contained electronic lock security system assembly
Inventor: ANDREOU DEMOS
IPC: E05B47/06
Filed: 1992-09-10
Abstract: The present invention provides for a locking mechanism (20) for use in a door (19) and the like. A remote handheld controller (400) transmits coded signals to an electronic door lock. A sensor/receiver receives the signals and provides the signal to a processor (505) which compares the coded signals against a predetermined stored signal. If the received coded signal matches the predetermined signal, then the processor generates control signals to actuate an electromechanical device, which acts about the locking axis, to enable or disable the locking latch. The user is then able to turn the door handled (30) in a normal manner. The coded signals are comprised of two separate signals which are transmitted in segments interleaved with one another. The first signal includes an entrance code, while the second signal provides information concerning the frequency over which the next segments will be transmitted. The processor uses the second signal information to tune the receiver. <IMAGE>

Title: Data transmission over telephone systems
Inventor: CLARK STEPHEN EDWARD
IPC: H04L27/36
Filed: 1994-12-23
Abstract: In a method of transmission of digital signals over links intended for audio purposes, the method involves the generation of pulses with a recovery period between the pulses. The recovery period can be modulated with a compensating signal or no signal. A further example is where audio and digital data is transmitted simultaneously by modification of the audio signal before transmission and adding the pulse signals to the audio. The pulses once detected can be removed or filtered from the audio on reception.
