    • An optics assembly for a color measurement system. The optics assembly includes at least one light tube array and a polarization effect minimization element. The optics assembly includes a diffuser, a photocell separator, a precision filter and a second light tube array is provided substantially contained in a housing. The color measurement system includes a multi-purpose filter and the optics assembly. Segmented light is mixed and the polarization qualities of the light are modified so to minimize the effects caused by angular adjustments. A diffuser mixes the segmented light. Additionally, the color measurement system includes an ambient light attachment for collecting light from the viewing area surrounding the computer display. The ambient light collected is then analyzed, and a viewing area profile is created. The viewing area profile then can be used by software to adjust the colors displayed on the computer displays.

    • A cable television system capable of decoding signals encoded in two different formats, A and B. Format A is identified by digital data on horizontal lines 10-13 in the vertical blanking interval and format B by digital data on horizontal lines 14-17 in the vertical blanking interval. Logic circuitry receives the vertical blanking interval data and supplies one pulse marking the beginning of the vertical blanking interval and an identifier pulse derived from digital data on horizontal lines 13 or 17. A format mode control switch includes a monostable timing circuit producing an output responsive to the vertical blanking interval pulse for a period terminating at approximately horizontal line 14. The timing circuit output is supplied along with the identifier pulse to the inputs of a flipflop for determining which of the decoders A and B is to be energized.

    • A sync signal separator includes a first monostable flip-flop, connected to be positive-edge triggered and nonretriggerable, with a first timing circuit for generating horizontal output pulses of slightly greater duration than input horizontal sync pulses, a second monostable flip-flop, connected to be negative-edge triggered and nonretriggerable, having a second timing circuit for generating a time duration greater than the normal duration of a vertical sync pulse and an OR gate having inputs coupled to receive input sync pulses and the output of the second monostable flip-flop for controlling the enable input of the second monostable flipflop. The output of the first monostable flipflop produces the horizontal output pulses and the output of the second monostable flipflop produces the vertical output pulses.
