Title: The Innovations of Christopher C Day
Introduction
Christopher C Day is an accomplished inventor based in Newtonville, MA (US). He holds a total of 5 patents that showcase his expertise in fluid control and signal detection technologies. His work has significantly contributed to advancements in various fields, particularly in the areas of fluid dynamics and physiological signal processing.
Latest Patents
One of his latest patents is a flow controller, which is a fluid flow control apparatus that includes a fluid flow control valve, a fluid flow sensor, and a fluid flow control circuit. This circuit receives a signal from the fluid flow sensor and outputs a signal to the fluid flow control valve. The fluid flow control circuit features an actual control circuit that outputs a signal related to the comparison of an actual flow signal and a desired flow signal. Additionally, it includes a desired flow comparator circuit that outputs a signal based on the comparison of the desired flow signal with a desired flow threshold signal, along with a summing circuit that provides a control signal based on these outputs.
Another notable patent is an adaptive signal detection system, particularly designed for physiological signals. This system detects signals subject to amplitude variations when their amplitude exceeds a threshold level. The threshold level is adaptive to both the amplitude and the rate of the signals, which helps to desensitize the detection process for sporadic artifacts and eliminates the need for automatic gain control of the signals prior to detection.
Career Highlights
Throughout his career, Christopher has worked with reputable companies such as American Optical Corporation and MKS Instruments, Inc. His experience in these organizations has allowed him to refine his skills and contribute to innovative projects that have had a lasting impact on the industry.
