    Abstract: A television sync signal generator adapted for ready conversion among various television standards includes a memory (216) in which information related to the magnitude of at least one component of a composite sync signal is stored at address locations each corresponding to at least one particular time in each recurrent television frame. A clock signal generator (212) addresses the memory (216) to sequentially read out the information so the sync signal can be reconstructed. By dividing the sync signal into four intervals which are selected by paging signals from one counter, a reduction in required memory capacity is achieved. For further reducing the number of memory addresses required, each memory address contains information relating to the instantaneous resolution or clock rate. A sample rate controller (820) is coupled to the memory for having the instantaneous clock address rate controlled in response to the contents of the memory.

    Abstract: The target is made up of a conducting layer on an insulating substrate with individual conducting regions electrically isolated from the main portion of the conducting layer. The individual regions are shaped to partially enclose an extension of the conducting layer so that an electrostatic charge on a conducting region will affect the ability of an electron beam to reach the portion of the conducting layer which is partially enclosed by a conducting region.

    Abstract: An electron gun is controlled by a system which stores the characteristics of the gun in a random access memory. The contents of the memory feed an electron gun driver which properly biases the gun. The characteristics of the gun are stored in the memory by using a collector to sense the electron beam. A comparator is connected to the collector and a reference brightness signal generator. The output of the comparator controls the storage of the characteristics in the memory.

    Abstract: The brightness signal for an image display device is digitally processed using an analog to digital converter to translate the signal into digital words. A primary shift register is connected to the output of the analog to digital converter. The primary shift register has a stage capable of containing a digital brightness word for each element in the display line of the device. The primary shift register has a plurality of parallel outputs being spaced X number of stages from each other. Each output is connected to a separate secondary shift register which has X stages.
