Title: The Innovative Contributions of Dave Dean
Introduction
Dave Dean is a notable inventor based in Ukiah, California. He has made significant contributions to the field of computing, particularly in video display technology. With a total of 3 patents to his name, Dean's work has influenced the development of personal computer systems.
Latest Patents
One of Dean's latest patents is a "Personal computer apparatus for holding and modifying video output." This invention provides data to a video display using a bitmap display memory organization and bitplane addressing. It features separate control for two bitplane backgrounds and eight reusable and easily movable sprites. Additional logic allows for dynamically-controllable interobject priority and collision detection among data in each of the bitplane backgrounds and sprites. A coprocessor is included to facilitate video beam-synchronized changes to data in registers, which frees the main processor for general-purpose computing tasks. Furthermore, a block image transferer is provided to rapidly copy data in large blocks from one memory location to another. In hold-and-modify mode, the color output circuitry holds the values for a previously displayed pixel while bitplane data modifies those values, allowing for the simultaneous display of a greatly increased number of colors.
Another significant patent is the "Beam synchronized coprocessor," which shares similar features with the previous invention. This computer also utilizes a bitmap display memory organization and bitplane addressing, with separate control for two bitplane backgrounds and eight reusable sprites. The coprocessor enables video beam-synchronized changes to data in registers, enhancing the efficiency of the main processor.
