Title: Innovations of James H Doyle, Sr.
Introduction
James H Doyle, Sr. is a notable inventor based in Orange, California. He holds a total of six patents, showcasing his contributions to the field of technology and engineering. His work primarily focuses on advancements in auditory stimulation and control circuits.
Latest Patents
One of his latest patents is the "Multichannel Implantable Inner Ear Stimulator." This device is designed to stimulate the auditory transmission branch of the 8th nerve. It utilizes electrodes that restrict the electrical field to specific nerve fiber groups, producing a gradient field for each channel. This design allows for sequential firing of nerve fibers during the channel stimulus pulse. The analog system stimulates nerve fiber channels in sequence, overlapping their previous channel by an amount equal to the shortest latency period. The pulse amplitude is modulated with audio information during the nerve fiber streaming. In the digital system, there is a single firing time for nerve fibers in a channel, with audio modulation in the form of frequency modulation of the channel sequence frequency.
Another significant patent is the "Fast Response Control Circuit." This circuit provides an output signal in minimal time after receiving an enabling input signal. It includes an amplifier that generates an output signal based on a variable input signal when the enabling input signal indicates that an output signal is desired. A feedback network and the amplifier define a control loop with a characteristic response time. When the enable signal is absent, a bias control minimizes the response time. This circuit is particularly useful in fluid mass flow controllers, providing rapid response to enabling input signals, especially at low fluid flow rates.
