Latest Patents

Roberts' latest patents include groundbreaking technologies that enhance data processing and visual display. One of his patents, titled "Associative Information Retrieval," focuses on the associative retrieval of data through superimposed code words. This technique utilizes circuitry that automatically generates codes and searches through stored code words to find matches for a given query code. The code generation employs reproducible pseudo-random techniques, eliminating the need for a pre-prepared code dictionary. The identification of matching codes is achieved by logically AND'ing selected bits from the stored codes, based on the query code.

Another significant patent is for "Animated Dithered Display Systems." This invention addresses the random cell scintillations observed in animated dithered displays. Roberts' approach involves establishing a hysteresis band around the dither threshold value assigned to each display cell. The hysteresis band is defined by upper and lower dither threshold values. The determination of whether the intensity of each picture element should be compared to the upper or lower threshold is based on the current state of the cell.
