Latest Patents

One of Sarofeen's latest patents is for a refreshable dynamic memory system. This innovative technology is designed to drive a video display by accessing each row of stored memory to provide one line of video. The memory row address counter is incremented multiple times during the horizontal retrace period, allowing for the sequential refreshing of memory rows before displaying another row. This cycle continues until an entire field is displayed, ensuring that a sufficient number of rows are refreshed continually within the storage time of the memory cells.

Another significant patent by Sarofeen is for an independent color adjustment apparatus used in sequential color imagery. This system acquires three successive monochrome images through a video system and displays them simultaneously on a screen as a color picture. A flash lamp sequentially illuminates a target through a color wheel, creating three primary color-separated images recorded in series by the video camera. The intensity of each image is controlled by varying the lamp's output during each imaging sequence, allowing for accurate color reproduction on the television screen.
