Title: Method and apparatus for the evaluation of wheel speed data in a motor vehicle
Inventor: MILLER BERNHARD
IPC: B62D15/02
Filed: 1993-08-19
Abstract: A method of evaluating wheel speed data in a two-axle motor vehicle comprises detecting first signals (nvl, nvr, nhl, nhr) representing the rotational speed of the wheels and determining, from the first signals, second signals (delta nv) and third signals (delta nh) representing the difference between the wheel speeds of the vehicle axles. Fourth signals (Zarvl, Zarvr, Zarhl, Zarhr) representing the relative movements between the vehicle chassis and the wheels (spring stroke travels) are also detected and are processed, preferably by means of characteristic value fields (1001v, 1001h) into correction values (Corv, Corh) for the second and third signals or for values (delta nv', delta nh') obtained by low-pass filtering thereof. By this method, different states of loading of the vehicle and non-linearities in the suspension systems can be taken into consideration in further processing of the wheel speed signals, for example for the determination of tyre state or steering angle. <IMAGE>

Title: Fuel pump for an internal combustion engine
Inventor: CAMPBELL-JONES HENRY DAVID MER
IPC: F02M41/14
Filed: 1996-08-24
Abstract: A fuel pump includes a pumping chamber and a spill valve 52 controlling fuel flow from the pumping chamber through a spill passage 54 to a reservoir, the spill valve 52 being controlled by a trigger valve 62 which supplies pressurised fuel through passages 56 to open the valve. A valve arrangement in the form of a plate valve member (66, Fig.2) closes the spill passage 54 during the subsequent filling of the pump working chamber to ensure that spilt fuel from the reservoir returns to the pumping chamber only via the trigger valve 62. This has the advantage that the spilt fuel and fresh fuel admitted to a passage 42, flow together into the working chamber through the same passage 40. In known pumps the two flows are in opposite direction which has a detrimental effect upon filling of the pump.

Title: Methods and apparatus for conveying objects
Inventor: MOSSE RICHARD WOLFGANG EMIL
IPC: B65B43/50
Filed: 1996-02-16
Abstract: Objects (14) such as transport holders containing carton blank are transferred between first and second conveyors (16, 20). The objects are held on the first conveyor prior to transfer and on the second conveyor after transfer by travelling magnets (44). At the instant of transfer, the attraction of the travelling magnet of the first conveyor is weakened by interaction with a fixed magnet (46) which diverts magnetic flux from the object (14), and simultaneously, the attraction of the travelling magnet of the second conveyor is boosted by interaction with a fixed magnet (46) which reinforces the flux path through the object (14). The precision of the timing of the transfer is thereby improved and is made readily adjustable by repositioning of the fixed magnets (46).

Title: PCB inspection system
Inventor: KWEON OH-KEUK
IPC: G01R31/28
Filed: 1997-09-24
Abstract: In a system to determine whether components are correctly inserted in a printed circuit board, a laser beam projects a spot onto the board S502 and the reflection of the spot is detected S503. The distance between the laser and the pcb is sequentially determined S504 for each point on the board from the detected image of the spot to form pixels. The boundary of holes and/or components on the pcb is detected as a change between the currently detected distance and that detected for the previous point and the data is digitised S505. The detected boundaries are compared to stored values S507 for properly inserted components to determine whether the pcb is acceptable. The boundaries detected are the edge of a hole in the board and the edge of a component in the hole.
