Title: Fred R Holdener: Innovator in Optical Element Actuation
Introduction
Fred R Holdener is a notable inventor based in Tracy, California. He has made significant contributions to the field of optical element actuation, holding a total of 3 patents. His work focuses on innovative devices that enhance the functionality and efficiency of optical systems.
Latest Patents
Fred's latest patents include the "Two Position Optical Element Actuator Device" and the "Bi-stable Optical Element Actuator Device." The two position actuator device utilizes a powered means to hold an actuation arm, which is attached to an optical element, in a first position. When the powered means ceases to receive power, a non-powered means drives the actuation arm to a second position. The optical element may be an electromagnetic (EM) radiation or particle source, an instrument, or EM radiation or particle transmissive, reflective, or absorptive elements. A bearing is employed to transfer motion and ensure a smooth transition of the actuation arm from the first to the second position. The bi-stable actuator device, on the other hand, utilizes a powered means to move the actuation arm between two stable positions, with a non-powered means holding the arm in either position. Similar to the first device, it also incorporates a bearing for smooth motion transfer.
