Title: Vehicular collision avoidance system
Inventor: KINOSHITA MASAHIRO
IPC: B60K31/00
Filed: 1997-04-01
Abstract: In order to prevent an own vehicle from colliding with an other vehicle, the own vehicle carries a stereogrammetric rangefinder 3, 4, 11. Repeated ranges to the other vehicle give its relative speed, and, in combination with the own vehicle's speed, its absolute speed and hence deceleration. The speeds and deceleration are used to determine a safe distance; if the measured range is less than this, warning buzzer 7 sounds. If the deceleration exceeds a threshold, the safe distance is increased.

Filed: 1997-11-19
Abstract: Software modules (e.g. dynamically loadable code such as java applets) are pre-emptively transferred in a data processing network from a host data processing system for execution on a client data processing system. The software modules are of a number of different types, each type providing a different service at the client system (e.g. e-mail, text editor etc). The host system determines the type of a first software module transferred to a client and makes a prediction, based on this determination, as to the type of software module that may next be required at the client. The predicted software module is then transferred to the client system in advance of any request for same from the client.

Patent GB-2333363-A (GB)
Title: Water leak detector
Inventor: JONES JOHN IFAN
IPC: G01M3/24
Filed: 1998-01-19
Abstract: A simple device is proposed for determining the presence of a leak in a water pipe. It is based on the wide-band detection and electronic amplification and processing of the sonic and ultrasonic emissions made by leaking water through a small hole or crack. The device has a widebandwidth and high sensitivity due to the novel coupling 2, 4 to the pipe 1, the design of a metal sounding box 5 for mechanical amplification and the use of an eliptical piezoelectric monomorph 3 as a transduction element. Electronic amplification is frequency dependent in order to provide compensation for the intensity/frequency relationship of the acoustic emissions and the influence of pressure on the sound generated. The device is easy to operate and has settings only for changes in pipe material.

Title: Expandable memory cassettes
Inventor: NISHIKITA SUSUMU
IPC: G06F12/06
Filed: 1995-10-13
Abstract: A secondary memory cassette 31 includes a connector 32 which can be connected to either a primary memory cassette 21 or a processing device body 12 such as a games machine. A predetermined pin of connector 24 is connected to ground, so that when primary memory cassette 21 is connected with secondary memory cassette 31, signal Sa becomes level L. Address transfer circuit 39 judges whether the connector has been connected to the primary memory cassette 21 based on signal Sa, and outputs an address transfer signal to memory 38 to change the memory allocation of that memory. Memory 38 outputs data corresponding to the address transfer signal and the address signal supplied from connector 32. The primary and secondary memory cassettes can be used alone or jointly, to satisfy the demands for a variety of game developments.

Title: Torsional vibration damper and method for its manufacture
Inventor: JAECKEL JOHANN
IPC: F16F15/30
Filed: 1998-07-30
Abstract: The centring unit 3 for the primary and secondary flywheels 2,4 of a torsional vibration damping apparatus 1 for use in the power train of a motor vehicle employs a radial bearing with a sleeve 34 which is or can be a press fit on or in one of the flywheels, and the still accessible internal or external surface of the sleeve is calibrated simultaneously with or following the press fit. The calibrated surface of the sleeve 34 is thereupon inserted into a socket or receives an extension of the other flywheel. The centring unit further utilises an axial bearing constituted by an annular collar 41b which can extend radially inwardly or radially outwardly of the sleeve. One of the bearings can be installed radially inwardly of the fasteners (418, Fig 12) which secure the primary flywheel to the output shaft of the engine, and the other bearing can be installed radially outwardly of such fasteners.

Title: Discharge lamp ignitor circuit
Inventor: LITTLEFAIR MATTHEW
IPC: H05B41/288
Filed: 1999-01-20
Abstract: An ignitor circuit for a gas discharge lamp 8 has an inductor 34 connected in parallel with a capacitive means 28, 30 which includes the lamp connecting lead capacitance 30, the inductor 34 and capacitive means 28, 30 forming a resonant circuit which generates a striking voltage across the lamp leads when driven at its resonant frequency. The capacitive means may include a variable capacitor so that the resonant frequency can be set at a desired value for various lengths of lamp lead. The ignitor circuit may be driven by a resonant inverter 2 having a resonant circuit formed by a capacitor 20 and an inductor 18 in series with an inductor 32 forming a primary winding on a transformer 26 having the inductor 34 as a secondary winding. The voltage developed across capacitor 20 is connected to a rectifier and DC link circuit 4 providing a DC supply voltage which is applied to a DC lamp (38, Fig.2) or to an AC lamp 8 via a low frequency inverter 6. The resonant frequency of the ignitor circuit 28, 30, 34 may be slightly higher than that of the resonant inverter 2. Inverter 2 is started at a frequency well above resonance, the frequency then being reduced towards resonance, so that the maximum ignitor voltage is generated simultaneously with maximum lamp voltage obtained from the inverter 2 via link 4 and inverter 6. Once the lamp strikes, lamp current flow through winding 34 saturates transformer 26 thus disabling the ignitor. To ensure that the transformer 26 is continuously saturated, after lamp starting, even when the square waveform lamp current passes through zero, the transformer may have an additional winding formed by two coils (56, 58, Fig. 3) connected to the DC link 4 to pass a saturating current but wound so that the voltages induced in coils (56) and (58) during ignition cancel one another. The lamp may be used for UV curing of material on a moving substrate in printing or coating apparatus, de-ionised water being passed through a quartz tube (74, Fig.5) to filter infra-red radiation.

Title: Optical device for roughness measurement
Inventor: KOURILOVITCH ANDREI
IPC: G01B11/30
Filed: 1999-02-01
Abstract: In an optical device for surface roughness measurement a one-dimensional interference pattern (3) is focused by an objective on a rough surface, by a primary beam (1). If the bandwidth (b) in the interference pattern is equal to the period of the roughness, then the light reflected from a rough surface has maximum or minimum intensity. By changing bandwidth (b) in the interference pattern (3) and synchronously measuring intensity of the light reflected from a rough surface, it is possible to obtain the information about bandwidth in the interference pattern when the signal has a maximum or minimum intensity. Alternatively, the light from a point source impinges on a rough surface and is reflected by it. The reflected light has defined distribution depending on the roughness size. To measure the roughness size it intensities of reflected light in specular direction and any additional direction are compared.
