Title: Richard Cawthorn: Innovator in Shellfish Evaluation Technology

Introduction

Richard Cawthorn, based in Cornwall, CA, is an accomplished inventor known for his innovative approach to evaluating live shellfish, specifically lobsters and crabs. With a focus on improving seafood quality assessment, he has made significant contributions to the industry through his patented technology.

Latest Patents

Cawthorn holds one patent titled "Shellfish Evaluation," which introduces a method and apparatus for determining the meat-to-water ratio (MC) in live shellfish. This technology utilizes a pair of transducer devices that assess the velocity of sound traveling through the shell of the shellfish without causing any damage. By strategically applying a sound-transmitting gel to enhance acoustic coupling, the devices measure sound velocity to classify the shellfish's readiness for harvest. For instance, a velocity of 1560 m/sec indicates an MC of 7%, denoting the shellfish's unsuitability for harvest, while a velocity of 1660 m/sec corresponds to an MC of 19%, signifying it is ready for market.

Career Highlights

Cawthorn is affiliated with Guigne International, Ltd., where he continues to advance shellfish evaluation techniques. His dedication to innovation in this field reflects a commitment to quality and sustainability in seafood production.

Collaborations

Throughout his career, Cawthorn has collaborated with notable coworkers, including Kenneth Klein and Jacques Guigné, contributing to a diverse environment that fosters ingenuity and progress in shellfish evaluation technologies.

Conclusion

Richard Cawthorn's contributions to the innovation of shellfish evaluation not only enhance the efficiency and accuracy of seafood quality assessments but also serve to benefit the broader industry. His pioneering patent demonstrates the potential of technology to transform traditional practices, ensuring that consumers receive only the highest quality shellfish products.
