Patent GB-2267564-A (GB)
Title: Automatic vehicle headlamp dipswitch
Inventor: WATHEN PHILIP JOHN
IPC: B60Q1/14
Filed: 1992-05-29
Abstract: The automatic vehicle head lamp dipswitch uses a simple 'fish eye' lens system 1 to form a small real image of the road ahead on the surface of a set of closely-spaced silicon photodiodes 3. If the image of an oncoming vehicle's headlights is formed on one of the photodiodes, its output will be greater than the others. The signal from each photodiode is compared electronically with a reference signal derived from the averaged output of all the photodiodes. If any is greater than this reference signal, then the vehicle's headlights are automatically dipped if they have not been dipped already by the driver. Provision is also made to prevent malfunction due to the light from oncoming vehicles being interrupted for short time intervals by obstacles, and also by excessive light levels falling on the photodiodes. <IMAGE>

Patent GB-2290897-A (GB)
Title: Magnetic cards
Inventor: CHENG LEE MING
IPC: G07F7/08
Filed: 1994-06-28
Abstract: Magnetic cards are provided with unique card signatures which include a number of bits, some of which have intermediate magnetic levels. As a result a card reader allocates randomly either a one or a zero to the intermediate level bits. The random allocation provides a test for the genuiness of the cards, since repeated readings of a signature will give inconsistent results with a genuine card. The intermediate level bits are formed as a result of inherent inconsistencies in the characteristic of a normal magnetic stripe 9 along its length, combined with selective use of masking to reduce field strength during recording. It is not possible therefore to readily, if at all, reproduce patterns of intermediate level bits in a duplicate because the stripe on the duplicate will have differently arranged inconsistencies along its length. <IMAGE>

Patent GB-2281981-A (GB)
Title: An image forming apparatus
Inventor: ARUGA TOMOE
IPC: G03G21/10
Filed: 1994-08-03
Abstract: An endless toner transport which connects a developing device (300) with a cleaning device (400) is disposed so as to pass through these devices in their resective longitudinal directions. The mixing of toner can be enhanced by returning recovered toner from the cleaner to the developing device and by supplying fresh toner to the cleaning device by using the toner transport itself, whereby the reuse of recovered toner and the reduction of the quantity of fresh toner used can be conducted more effectively. In the processes of transporting toner from the developing device to the cleaning device and from the cleaning device to the developing device, toner can effectively be stirred and mixed by utilizing oscillation generated in the endless toner transport which can be in the form of a coil spring (510) so that an additional stirring member is not required, thereby allowing the developing device, and hence the entire image forming apparatus, to be greatly reduced in size. The coil spring may be held in groove (222) in the cleaner (400) and is open at lower end (531) in developer (300) so it can stir the toner. Fresh toner is supplied from container (600) preferably via opening in wall (230). <IMAGE>
