Patent GB-2299394-A (GB)
Title: Computer input devices
Inventor: FRAZER STEPHEN OLIVER
IPC: G06F3/0354
Filed: 1995-03-31
Abstract: The computer input device consists of two oppositely facing touch- and position-sensitive panels 5 which are set in a suitable mounting. Most usually, the mounting 1 is held or supported in one hand of the user while the opposed thumb and a finger (usually the forefinger) of that hand touch one or both panels. Depending upon the position and, e.g., relative movements of positions of the contact points of thumb and forefinger with the respective panels, a wide variety of different manipulative commands may be distinguished by suitable circuitry and translated, e.g., into analogous manipulative commands to change the position of a representation of a three-dimensional object viewed on the computer screen.

Title: Constant speed control system with accelerator override for an electric vehicle
Inventor: SUZUKI AKIRA
IPC: B60K31/00
Filed: 1996-02-01
Abstract: When the constant speed running mode is selected and the vehicle speed is designated as a given vehicle speed, the motor torque needed for the constant speed running is calculated and instructed to the motor controller. When the accelerator pedal is depressed during the constant speed running, the motor torque is compared with an accelerator torque which is calculated to correspond to the amount of depression of the accelerator pedal. If the accelerator torque is larger than the motor torque, the vehicle is accelerated and if the accelerator torque is smaller than the motor torque, the vehicle is kept running at or is returned to the designated constant speed. Other embodiments also compare the speed of the vehicle with the designated constant speed.

Title: Method of recalibrating electronic scales
Inventor: BASS EDWARD R
IPC: G01G23/01
Filed: 1996-03-04
Abstract: A method of recalibrating an electronic scale allows the scale to indicate a weight value which is independent of variations in the relative magnitude of the force of gravity as between the site where the scale is operating and the site of original calibration. The method utilizes the known fact that gravity varies from place to place as a function of elevation above sea level and proximity to the equator. Data relating to the effect on the scale of variations in the gravitational force between a site of origin and a number of possible sites of installation are preferably placed in memory in the scale at the site of origin where the scale is initially calibrated. When data indicative of the relative magnitude of gravitational force at the site of installation are then selected or otherwise entered into the scale, a microprocessor 80 therein adjusts the factory calibration to compensate for the relative magnitude so that the digital readout 96 of the scale indicates accurate weight for an article placed thereon at the site of installation. The scale described is for weighing mail pieces and uses a strain gauge load cell.

Filed: 1997-07-01
Abstract: An imaging system (10) for imaging a substrate surface (14) at several imaging wavelengths comprises a replaceable beam generating module (36), a spinning mirror (34) and a controller (26). The beam generating module generates an imaging beam in dependence on beam command signals. The imaging beam has a wavelength which is a one of the plurality of imaging wavelengths. The beam generating module presents the imaging beam along a prescribed path, and also generates wavelength signals indicative of the imaging beam wavelength. The controller receives the wavelength signals, and generates the beam command signals in dependence on the wavelength signals. The beam command signals control generation of the imaging beam in accordance with a prescribed pattern to image upon the substrate surface. The system is readily adaptable for different substrates, eg film and thermal media, which are sensitive to different wavelengths. Thermal media offer the advantages of not requiring chemical processing and of producing sharper images.

Title: A vehicle bumper with an air bag
Inventor: MOORE DARRYL
IPC: B60R21/34
Filed: 1998-04-25
Abstract: The vehicle bumper 1 has a bumper protrusion 3 and an air bag mechanism 4 that can deploy an air bag 6 below the bumper in the event of a collision. The air bag in combination with the protrusion presents a larger surface extending from a lower level and this acts to protect a pedestrian's leg 7 from bending during a collision. On deployment of the air bag a lead surface 8 of the bumper protrusion and a front surface of the bag align to provide a consistent collision plane CP. To detect a collision or when one may occur the bumper has or is connected to sensor means which determine when to deploy the bag. Typically, several air bags 6 are provided that, when deployed, constitute a composite barrier below the bumper protrusion 3. The bumper is particularly suitable to high riding 4x4 off - road vehicles as the vehicle retains a sufficient ground clearance necessary to avoid contact with rough terrain when the bag is not deployed but in the event of a collision the bumper provides a broad surface extending from a low height.
