Title: Innovations of William L Still
Introduction
William L Still is a notable inventor based in Purcellville, VA (US). He has made significant contributions to the field of telemetry and radar technology. With a total of 3 patents, his work has advanced the capabilities of communication and detection systems.
Latest Patents
One of his latest patents is titled "Bore telemetry channel of increased capacity - Apparatus and method for signaling within a drill hole without disturbing an ongoing drilling operation." This invention achieves high data rates by utilizing phase and/or amplitude modulation techniques. These techniques enable information transfer rates that exceed the data bit rates being transmitted. The modulation method provides a multi-level signal, optimizing the use of the amplitude/phase space available. The invention significantly increases the carrying capacity of the communication channel by leveraging the dispersive characteristics of electromagnetic propagation in a borehole. Lower frequencies propagate at a slower velocity and with less attenuation than higher frequencies, allowing for improved data rates at lower frequencies.
Another notable patent is "Synthetic pulse radar including a microprocessor based controller." This invention pertains to pulse radar detection of targets in extended media, including natural phenomena such as oil, coal, and ore deposits within the earth. The system employs a synthetic pulse formed from a Fourier spectrum of frequencies generated and detected by digitally controlled transmitter and receiver circuits.
