1. A method for selectively locking a notch plate to a pocket plate such that the notch and pocket plates rotate together, wherein the pocket plate includes at least one first direction strut and at least one second direction strut, the method comprising the steps of:
identifying a pocket rotational speed of the pocket plate;
identifying a notch rotational speed of the notch plate;
modifying the notch rotational speed of the notch plate such that the notch rotational speed approaches the pocket rotational speed;
pivoting the at least one first direction strut such that it extends past the pocket plate allowing the first direction strut to engage the notch plate;
matching the notch rotational speed to equal the pocket rotational speed to allow the at least one first direction strut to extend into the notch of the notch plate;
decreasing the notch rotational speed to less than the pocket rotational speed such that the notch plate engages the at least one first direction strut; and
pivoting the at least one second direction strut to engage the notch plate preventing relative motion between the notch and pocket plates in either direction.
