Title: Innovations by David M Pfund
Introduction
David M Pfund is an accomplished inventor based in Richland, WA (US). He has made significant contributions to the field of ultrasonic technology, particularly in the cooking and fluid characterization domains. With a total of 2 patents, his work showcases innovative methods that enhance the understanding and control of cooking processes and fluid dynamics.
Latest Patents
One of Pfund's latest patents is titled "System and technique for ultrasonic determination of degree of cooking." This invention describes a method and apparatus for determining the doneness of food during cooking. Ultrasonic signals are passed through the food, and the changes in transmission characteristics are measured to ascertain when the food has reached the desired level of cooking. This method utilizes a heated fluid to cook the food, providing a reference for comparison with the transmission characteristics of the food-fluid ultrasonic path.
Another notable patent is "Ultrasonic system and technique for fluid characterization." This invention involves a pair of multi-frequency ultrasound transducers that surround a fluid flow. The system operates under computer control in both mono-static and bi-static modes at multiple frequencies. In the mono-static mode, pulsed wideband Doppler shift measurements are used to create a velocity profile across the fluid flow. This data can be combined with measured pressure drops to generate a rheogram, which plots shear stress against shear rate. The bi-static mode enhances the accuracy of the velocity profile and provides additional material property information.
