Abstract: A system for attaching overlays to an electronic display comprises (a) at least one bracket defined by an outer face and an inner face and (b) at least one second attracting member comprising a layer of pressure sensitive adhesive. The bracket has an L-shaped cross-section comprising a first leg and a second leg. The inner face of the first leg comprises a first attracting member and the inner face of the second leg comprises a layer of pressure sensitive adhesive.

Abstract: A device for securing an object to a ceiling includes a threaded rod, a bracket and a spring-loaded tab. The spring-loaded tab has a tab portion with an outer surface. The tab portion is rotatable about an axis perpendicular to the threaded rod. When the device is attached to the object and the object moves into an opening in the ceiling for installation to the ceiling, the tab portion is urged from an extended position to enable the object to pass through the opening. Subsequently, the tab portion returns to its extended position such that the object can be temporarily supported by the tab within the ceiling opening. The bracket is configured so that during a removal process, a portion of the bracket urges the tab portion inward from the extended position to enable the object to be removed from the ceiling opening.

Abstract: A portable public address (PA) speaker comprises an enclosure constructed and arranged for positioning at a first position having a vertical orientation to output audio shaped for a first acoustic coverage area, a second position having an angular orientation to output audio shaped for a second acoustic coverage area, and a third position having a horizontal orientation to output audio shaped for a third acoustic coverage area. The weight of the speaker rests on a bottom surface of a base when in the first position having the vertical orientation or the second position having the angular orientation. The weight of the speaker rests on a side surface when in the third position having the horizontal orientation.
