Title: The Innovative Contributions of James L Allen
Introduction
James L Allen is a notable inventor based in La Crescenta, California. He holds a total of 5 patents that showcase his expertise in advanced measurement and control technologies. His work has significantly impacted various fields, particularly in noncontact temperature measurement and acoustic control systems.
Latest Patents
One of Allen's latest inventions is a noncontact temperature pattern measuring device. This device employs laser pyrometer techniques to accurately image the true temperature distribution on a target without physical contact or prior knowledge of the target's localized emissivity. The pyrometer features a high-definition laser beam and photodetector, both designed for narrow focus. It is mounted on a mechanism that allows precise aiming and focusing on specific points of the target surface. The pyrometer is swept over the area to capture temperature measurements at each focused point.
Another significant patent involves acoustic controlled rotation and orientation. In this invention, acoustic energy is applied to two locations within a chamber to control the rotation of a levitated object. By utilizing two acoustic transducers that apply energy of a single acoustic mode, the system can levitate the object in three dimensions and control its rotation. Slow rotation is achieved by establishing a large phase difference and/or pressure ratio of the acoustic waves, followed by adjustments to maintain controlled rotation. This technology also allows for the measurement of an object's sphericity based on its response to the applied acoustic energy.
