Title: Glen D Jones: Innovator in Image Data Encoding
Introduction
Glen D Jones is a notable inventor based in Orange, California. He has made significant contributions to the field of image data encoding, holding a total of 3 patents. His work primarily focuses on enhancing data compression techniques through innovative hardware implementations.
Latest Patents
One of his latest patents is titled "Hardware implementation of 2 line/11 element predictor." This invention involves a predictor bit pattern that utilizes selected bits from current and previous raster scan lines. The method aims to predict multiple bits per clock, which is crucial for data encoding to improve compression efficiency. By comparing the current bit in a bit stream to the predicted value, the system outputs a one when the two values differ. This efficient predictor reduces the number of ones in a bit stream, thereby increasing zero run lengths and enhancing the efficiency of run-length encoding systems. The described bit pattern effectively predicts text data and halftone data while minimizing hardware costs.
Another significant patent is the "Hardware implementation of 4-pixel code encoder." This circuit encodes image data received in four-bit nibbles, which can either be all-zero or terminating nibbles containing at least one non-zero bit. The output consists of a series of code words, each a multiple of four bits and up to twenty-four bits long, packed into eight-bit output words. The circuit employs PROMs for look-up and control elements, along with a pipeline of registers to facilitate high-speed operation.
