Abstract: An exciter assembly for use with a flat panel loudspeaker system including a panel having a core, an inner sheet coupled to an inner surface of the core and an outer sheet coupled to an outer surface of the core. The exciter assembly may include an exciter having a voice coil assembly attachable to the outer sheet of the panel, the voice coil assembly having a lock pad, and a lock base releasably engaging the lock pad and attachable to the outer sheet of the panel, to vibrate the panel to generate sound energy; and an exciter support bracket connected to the exciter housing and attachable to the outer sheet of the panel.

Abstract: A window shade handle system includes a handle section and a post configured on each end of the handle section. Each post has four sides that are restrained by a post channel in a track section. The post channel restrains each side of the post. The handle section is constructed of a front handle section affixed to a rear handle section. The front handle section and the rear handle section form a channel that accommodates a window shade wrapped about a rod. The channel may have a raised portion that physically contacts the window shade while the handle sections otherwise allow the shade to expand and contract.

Abstract: A system is described for determining if two seat buckles are attached. The system includes seat belt portions and corresponding seat buckle members. The system also includes a sensing element located within a first seat buckle member and configured to output signals corresponding to one or both of attachment and non-attachment between the seat buckle members. A transmitter located within the first seat buckle member is configured to receive the signals from the sensing element. The transmitter transmits unique identification information, corresponding with a location of the seat belt, and data corresponding to the signals received from the sensing element. A display unit is configured to receive the unique identification information and data from the transmitter and provide a display indicative of an attachment status between the seat buckle members.
