Title: Optical velocity measurement
IPC: G01S17/50
Filed: 1978-12-27
Abstract: An optical velocity measuring apparatus for use in a hovercraft, navigation system, consists of two photo-detectors 8, 9, arranged to view a relatively moving surface 4 through a rotating disc bearing a spiral continuous grating line 6 which provides the effect of a grating like sensitivity pattern for each detector moving in orthogonal directions. The movement of each sensitivity pattern contributes a component of velocity which combines with the velocity of the surface relative to the apparatus so that over a given range of relative surface velocities of either sense about zero the velocity representative frequency component of the signal generated by each detector is always in respect of a velocity of one sense only. In another embodiment the grating and detectors are replaced by a pair of orthogonally disposed, scanned, charged coupled device arrays. <IMAGE>

Title: Variable resistors for use in the sender units of vehicle liquid fuel gauges
IPC: G01F23/36
Filed: 1980-09-09
Abstract: In a method of forming a variable resistor having a contact member movable to vary the effective resistance of the resistor, first and second layers (3, 4) of resistance material (e.g. resistance ink) are provided on a substrate (1) and are electrically connected in series. The layers (3, 4) are of different specific resistivities and cover different areas of the substrate (1). The profiles of the layers (3, 4) are so trimmed that movement of the contact member from the lowest effective resistance position to the highest effective resistance position over for example a grid of parallel conductor bars (2) on the substrate causes the effective resistance to be provided by a progressively increasing area of the first layer (3) and then by a progressively increasing area of the second layer (4) electrically in series with the whole area of the first layer (3). The final resistor may thus comprise the areas 14, 15 for movement of the contact member over a limited angle for one particular fuel tank, or the areas 16, 17 to give the correct resistor law and range for a different tank. <IMAGE>
