Abstract
In accordance with at least one aspect of this disclosure, a system can include, a moveable component configured to move between one or more positions, a biasing member operatively connected on a first side to bias the moveable component to a respective one of the one or more positions, and a preload member operatively connected to provide a force to a second side of the biasing member. An actuator can be operatively connected to move the preload member in response to a signal from a controller.
