Abstract
A dynamically resonant system including a linearly movable element having a neutral position and a range of excursion centered on the neutral position, a spring-like element for urging the movable element toward the neutral position, the resonant system having a natural resonant frequency dependent on the spring characteristics of the spring-like element, the spring-like element having a temperature sensitive member that causes the spring characteristics to vary with temperature of the member.
Claims5
A resonant system comprising
- a linearly movable element having a neutral position and a range of excursion centered on said neutral position, and
