Title: Innovations of Patrick S Grant
Introduction
Patrick S Grant is an accomplished inventor based in Sunnyvale, CA. He has made significant contributions to the field of technology, holding a total of 3 patents. His work primarily focuses on advanced data compression techniques and adjustable filters.
Latest Patents
One of his latest patents is related to memory-based vector quantization. This apparatus is designed to perform two stages of high-speed compression of vector data inputs. The process involves compressing and encoding two input channels of vector data through a vector quantizer encoder, providing a first stage of data compression. The output from the first encoder is then further decoded, compressed, and encoded using a novel high-speed computing mapping means, which can be implemented as a look-up table. This innovative approach results in a vector quantized encoded output that achieves double the previous data compression of a single stage, with minimal degradation of data quality.
Another notable patent by Patrick is for a radiation-controlled filter with photoconductor means and feedback. This invention discloses an adjustable filter that utilizes photoconductors, whose resistance is modified by a variable-intensity radiation source. The design includes a feedback loop to compensate for thermal changes, enhancing the filter's performance.
