Latest Patents

David R. Weir holds a patent for a "Release actuator employing components with different coefficients of thermal expansion." This actuator design includes a capturing part, a retained part, and a heating element. The heating element applies heat to either the retained part or the capturing part, depending on the selective application of power. The capturing part is designed to attach to a first object and has a first coefficient of thermal expansion, while the retained part attaches to a second object and has a second coefficient of thermal expansion. The retained part can be inserted into the capturing part in a first state, held in contact via an interference fit in a second state, and ejected in a third state. The application of heat facilitates transitions between these states, showcasing a clever use of thermal dynamics in actuator design.
