Title: Innovations of James Joe Allen
Introduction
James Joe Allen is a notable inventor based in Albuquerque, NM (US). He holds a total of 13 patents, showcasing his significant contributions to the field of micromechanical structures and devices. His work has advanced the technology surrounding micromirrors and active hinge apparatuses, making him a prominent figure in his area of expertise.
Latest Patents
One of his latest patents is the "Extended-range tiltable micromirror." This invention discloses a micromirror device that is suspended by a progressive linkage, featuring an electrostatic actuator located beneath the micromirror. The design includes a pair of torsion springs that operate similarly to a four-bar linkage with spring joints. This innovative linkage provides a non-linear spring constant, allowing the micromirror to tilt at any angle within its range, free from electrostatic instability or hysteretic behavior.
Another significant patent is the "Apparatus for raising or tilting a micromechanical structure." This active hinge apparatus can raise a micromechanical structure, such as a plate or micromirror, on a substrate. It utilizes teeth protruding from an axle that supports the micromechanical structure. A rack engages these teeth to rotate the axle, raising and tilting the structure. The motion is powered by an actuator, which can be mechanically powered or electrostatic. An optional latch can lock the structure in an 'erected' position.
