An exemplary embodiment of the present invention is a display apparatus. The fastener tab has a first elastic region that extends laterally outward from a waist region of the garment, a second elastic region that extends laterally outward from the first elastic region, and a grip that is attached to an outboard portion of the second elastic region. The requester node receives a mapping corresponding to the group of resources that may indicate that a lock already exists for a second resource in the group. In this manner, compression deformation of the inner roller is suppressed when a load is applied to the inner roller. A visual representation of the percept may be generated.
