  • Patent number: 4234890
    Abstract: A system is described for automatic adjustment of a color television camera for correcting for geometrical errors in the raster and amplitude errors in the video. The system includes means for measuring the errors, positions, or amplitudes of the camera output signals at different locations of the red, green, and blue rasters for simultaneously providing detected signals representing the detected error positions or amplitudes of these locations to a signal processing means. The processing means selectively and separately processes said detected signals according to a plurality of algorithms for producing a plurality of correction signals. The correction signals are applied to the camera for adjusting the camera according to all of the correction signals before remeasuring the rasters.

  • Patent number: 3955353
    Abstract: A converter utilizes a low voltage battery to develop a higher potential by the use of capacitors which are charged sequentially according to digital waveforms provided by counting type circuits and gates. The charge transfer circuits afford a low impedance charging path and a high impedance discharge path via a series of transmission gate controlled capacitors.The apparatus permits the conversion of low battery voltages while being completely compatible with ultra-miniature electronic systems.
