Embodiments of the present invention are directed to control of lighting systems at individual-light-fixture, local, regional, and larger-geographical-area levels. In order to fix the winding support inside an external rotor housing, a rigid connecting device having a hollow cylindrical connecting element made of fiber reinforced plastic is provided on the torque transmitting side. Further, the phase-locked loop can include a resettable counter, which generates a digital phase deviation signal corresponding to the identified phase deviation. Relevancy is used to determine the priority of how itemsfeed stories are presented for a user. In some embodiments, the covering may include more than one exposed loop for attaching to more than one loop receiving member located on the covering, as well as more than one footwear loop anchor located on an article of footwear.
