Title: Lee A Cotterill: Innovator in Rotary Switch Technology
Introduction
Lee A Cotterill is a notable inventor based in San Jose, CA, with a focus on innovative switch technology. He holds a total of 4 patents that showcase his expertise in creating advanced control systems. His work has significantly contributed to the field of user interface design, particularly in the realm of rotary switches.
Latest Patents
Cotterill's latest patents include the "Variable Scale Rotary Switch" and the "Multi-Parameter Variable Scale Rotary Switch." The Variable Scale Rotary Switch is a sophisticated switch assembly that can vary at least two controllable parameters. It features a pair of nested coaxial rotary knobs, each connected to sensors that determine the radial position of a reference point on each knob. This design allows for one-handed operation, enhancing user convenience. The sensors are linked to a magnetic clutch that engages to prevent rotation of one knob when it reaches a predetermined position. A computer can be integrated with the system to manage the clutch and sensors, allowing for programmable control of the switch's limits.
The Multi-Parameter Variable Scale Rotary Switch builds upon this concept, offering additional functionality. It retains the dual-knob design and integrates a computer to control the switch's parameters dynamically. The central button serves multiple purposes, including acting as a start/stop switch and changing the functions controlled by the knobs. This innovative approach allows for immediate equipment shutdown by pushing the knobs down, ensuring safety and efficiency.
Career Highlights
Throughout his career, Cotterill has worked with prominent companies such as Electro-Sound, Inc. and Sony Corporation of America. His experience in these organizations has provided him with valuable insights into the development of user-friendly technology.
