Abstract
A method of operating an electromagnetic latch assembly of a type that includes an electromagnet and a latch pin that is stable independently from the electromagnet in both first and second positions includes energizing the electromagnet systematically over a period in a manner that enhances the functionality of the electromagnetic latch assembly without causing the latch pin to move between the first and second positions. The period may be a period over which the electromagnetic latch assembly is too cold and the electromagnet may be energized in a manner that is effective for heating. Alternatively, the period may be one over which the electromagnetic latch assembly is subject to high inertial forces and the electromagnet may be energized in a manner that is effective to enhance latch pin retention.
