Abstract
An enhanced escapement mechanism provides improved isolation of energy and torque for an oscillation system, e.g. a pendulum. In an exemplary embodiment, during a first phase, a pendulum releases an impulse arm that is decoupled from a main wheel, which falls and impulses the pendulum, such as at or near the middle of the pendulum swing. In a second phase, the impulse arm continues to fall, becoming totally detached from the pendulum, wherein the falling impulse arm releases the main wheel, which restores the impulse arm to its initial position. The main wheel continues to rotate until it is no longer in contact with the impulse arm, and is captured, such that the process may be repeated. While the enhanced escapement mechanism typically provides an impulse to an oscillation system during each period, alternate embodiments provide an impulse for each of a plurality of periods, e.g. once every ten periods.
