    • 1,147,995. Fluid-pressure brakes. S. H. FRISHAUF. 4 Oct., 1966 [23 Oct., 1965], No. 44186/66. Heading F2F. In a braking system of a front wheel drive vehicle, brakes 16a, 16b provided on the rear wheels 15a, 15b are applied, independently of any other brake applying means, by a valve 36 which controls the supply of hydraulic fluid from a pump P driven by the engine 1, the valve 36 being controlled by a signal from a device 10 which senses whether the front wheels 14a, 14b are in the driven or overrun condition and, in the latter event, causes the valve 36 to supply fluid from the pump P to the brakes 16a, 16b to reduce or eliminate the tendency for the vehicle to slew about its front wheels in this condition. The embodiment shown includes a one-way clutch 30, so that the braking of the rear wheels replaces engine braking on the overrun, the device 10 comprising rotating magnets 31 on driven shaft 11 which co-operate with coils 32 carried by driving shaft 3 to give an electrical signal at 33 when the speed of shaft 11 exceeds that of shaft 3 owing to free-wheeling of the clutch 30 on the overrun. The electrical signal energizes, either directly or via an amplifier, a winding of the valve 36 to cause fluid to be supplied to a line 18 which feeds the cylinders 16a, 16b. A master cylinder 19, e.g. one of two for supplying fluid independently to front and rear wheel brakes (the former not being shown) also communicates with the line 18, a check valve 37 preventing reverse flow to the pump in normal brake operation. The clutch 30 is arranged to be locked through an operating cable 21 when the gear lever 20 is moved into reverse. In an alternative embodiment (Fig. 2, not shown) the one-way clutch is omitted and the drive to the front wheels includes a worm or other drive gear which can be arranged, e.g. by sensing axial movement of the worm, to indicate the direction in which torque is being transmitted between the engine and front wheels, and to control directly the position of a valve plunger controlling the supply of fluid from the pump 34.

    • There is disclosed an apparatus for correcting the color of objects appearing in a video image. The apparatus comprises: 1) a frame buffer for receiving and storing a first video frame from an incoming baseband video signal; 2) a memory for storing known pixel data corresponding to a plurality of known icons, the known pixel data comprising true color data values associated with the plurality of known icons; and 3) a color correction controller for comparing captured pixel data from the stored first video frame with the known pixel data stored in the memory and detecting a first actual image of a first known icon appearing in the stored first video frame. The color correction controller also compares a first true color data value associated with the first known icon and a first actual color data value associated with a first actual color in the first actual image of the first known icon. In response to the comparison, the color correction controller determine a first color correction factor associated with the first actual color data value.

    • A faceted surface has first and second facets which deflect respective first and second light beams to produce first sub-beams which alternate with second sub-beams. The faceted surface may be a reflector having first facets at 120° to second facets for mixing light beams which are incident at 120° to each other. 100% of reflected sub-beams from each source alternate with 100% of sub-beams from the other source. The faceted surface may also be a refractor which is part of a transparent block having two parallel faceted surfaces. A first refractive surface refracts parallel light beams to produce diverging beams which are each split into spaced apart sub-beams by the second refractive surface. 50% of refracted sub-beams originating from each source alternate with 50% of refracted sub-beams of each adjacent source.
