Title: Innovations of Steve Purcell
Introduction
Steve Purcell is an accomplished inventor based in Mountain View, CA. He holds a total of five patents, showcasing his contributions to technology and innovation. His work primarily focuses on power conversion systems and video data compression.
Latest Patents
One of Purcell's latest patents is a gearless power conversion system employing two electric machines. This innovative system incorporates two or more electric machines to assist in powering a vehicle through energy conversion. The first electric machine is coupled with a human-powered input and acts as a generator when the human power input is insufficient. This system can be applied to bicycles, where the first electric machine is connected to the crank. Additionally, a bi-coupled electric machine may be utilized, which includes both the first and second electric machines with a common rotor or stator. The power generated can either be used directly to propel the vehicle or stored in a battery for later use.
Another significant patent is for a system designed for the compression and decompression of video data using discrete methods. This digital video compression system converts matrices of pixels in the RGB signal format into YUV representation. The process includes selectively sampling the chrominance components and applying a discrete cosine transform (DCT). The system also features a quantization step that eliminates DCT coefficients below preset thresholds. The compressed video signal is further encoded using Huffman codes, and the decompression process is essentially the reverse of the compression steps.
