Abstract: Various embodiments of the present disclosure relate, generally, to a control system for a movable partition. In one embodiment, the control system is an access control system that includes a lock control interface and a remote line interface at which lock modes are asserted, and which are communicated to a door controller. Protocols installed at the controller enable the controller to provide control signals to the movable partition responsive to the various lock modes asserted at the lock control interface and remote line interface.

Abstract: An apparatus for balancing a fan or other spinning product may comprise a motor for spinning the fan, an accelerometer for gathering sampling data from the fan while it is spinning, a laser source, a laser redirection platform comprising a spinning mirror configured to track the rotational speed of the spinning fan, and a control module. The fan and laser redirection platform may each have an index hole for tracking, using respective photocell transmitters and receivers, rotational speed and phase. The control module may direct the fan motor to spin up the fan, collect balance data, and determine a location on the fan for burning a hole to correct imbalance. The control module may direct the laser redirection platform to spin at the same rpm as the fan, and such that a laser redirection mirror directs a laser beam from the laser source toward the target burn location on the fan.
