Title: The Innovations of Leonard T. Armstrong
Introduction
Leonard T. Armstrong is a notable inventor based in Worcester, MA, who has made significant contributions to the field of electric actuators. With a total of three patents to his name, Armstrong's work focuses on enhancing the functionality and safety of electric actuators through innovative designs.
Latest Patents
Armstrong's latest patents include an electric actuator with a fail-safe mode of operation. This invention provides an electric actuator that incorporates a mechanical stop coupled to the output through a transmission. The design features a brake that engages to establish a pathway between the first driving source and the output, while disengaging to create a second pathway through the second driving source. The mechanical stop restricts the output from rotating beyond a fail-safe position, ensuring safety in operation. Another patent details an electric actuator that includes a first driving source coupled to an output through a first pathway, and a second driving source that positions the output at a fail-safe position upon loss of electrical power. This design also features a differential that stores energy from the first driving source in the second driving source, along with a switching controller to manage the transmission pathways.
