Methods, systems, and devices for updating access permissions of users in an access control system are described. Both the wax container and vacuum cap are displayed in a transparent plastic container. Each of the second plurality of apertures of the targeting arm are configured for targeting of a bone fastener to one of first plurality of apertures. In other embodiments, the reduction is effectuated through corresponding application of appropriate filtering to correspondingly cancel the respective interfering signals, whenever an interference is predicted to occur. A first drive feature rotational axis is defined for the first drive feature and is fixed relative to the base as the main shaft rotates.
