Title: Innovations of William K. Pratt
Introduction
William K. Pratt is a notable inventor based in San Jose, CA. He has made significant contributions to the field of data compression and video teleconferencing. With a total of 2 patents, his work has paved the way for advancements in communication technologies.
Latest Patents
Pratt's latest patents include a low bandwidth video teleconferencing system and method. This innovative system employs novel data compression techniques, allowing continuous transmission of imagery at a rate of 9600 bits per second. The system utilizes a sketch coder that converts grey scale images into sketches or line drawings, which represent the principal boundaries and shading for depth. The bandwidth required for transmitting these sketches is compressed using two-dimensional run-length coding techniques, effectively exploiting redundancies to generate a binary transmission code.
Another significant patent is the dual mode facsimile coding system and method. This technique features symbol recognition and extended run-length coding methods. It operates by isolating digital raster data that represents valid alphanumeric characters and document symbols. The first symbol encountered is stored in a memory library, and as new symbols are detected, they are compared with existing entries. If a match is found within a predetermined tolerance, a library identification code is generated and transmitted. Otherwise, the new symbol is added to the library, and its digital pattern and location are transmitted.
Career Highlights
William K. Pratt has been associated with Compression Labs, Inc., where he has contributed to the development of innovative technologies in data compression and telecommunication. His work has been instrumental in enhancing the efficiency of video communication systems.
