Abstract: The disclosed device is an additional, normally-closed relay positioned in line with the ignition switch and the functionality controlled by the OEM, normally-open relay. When the aftermarket system is in the disarmed state, the normally-closed relay is dormant in its closed position, thereby allowing the circuit to complete its intended loop. When the aftermarket security system is enabled, the normally-closed relay will open the current flow and prevent the current from reaching its target, thereby disrupting or disabling the operation of the vehicle function. If the normally-closed relay fails, it fails in its closed position, thereby not affecting the OEM system.
Abstract: A speaker system including in combination a speaker and surface mounting apparatus is disclosed. The speaker system has an adapter that secures the speaker system to the wall. A speaker box is secured to the adapter and has at least one speaker that is secured to at least one speaker portal wall of the speaker box, or speaker enclosure. A speaker portal wall is disposed in a plane that is oriented at an angle relative to the wall and is disposed outboard of the wall. A surface mounting adapter has a peripheral edge portion and a planar portion extending between the peripheral edge portion and the enclosure structure. Portions of at least four sides of the enclosure structure protrude from the planar portion of the wall. Other portions of at least four sides of the enclosure structure are recessed relative to the planar portion of the wall.
Abstract: A system and method for controlling remotely controlled components of a plurality of vehicles in response to a short range common signal emitted by a transmitter that can operate the components only during specified time periods. A transmitter can be programmed to provide a relatively long range customer signal that can operate the components at any time. The system and method are operative on a mutually exclusive basis wherein the remotely controlled components only respond to the common signal or the customer signal.

Abstract: An in-vehicle audio/video system broadcasts audio programming within the vehicle at low power over a system audio channel that is received by a wireless radio frequency receiver that operates in a restricted range to increase tuning resolution and allow fine tuning of the system audio channel. The receiver includes a frequency range adjuster coupled to the tuner. The range adjuster is operable in first and second modes. The first mode selects the frequency range as a full range, and the second mode selects the frequency range as the restricted range.

Abstract: An antenna for a vehicle including an antenna mast, a mast base and subsurface base that are assembled by means of a fastener that connects the mast base and subsurface base to a body panel of a vehicle. The mast base is a solid member that does not include any openings or conjoint members that could provide a leak path through the mast base. A fastener extends through a hole in the subsurface base and is retained as a subassembly with the subsurface base by means of a retainer clip. The subsurface base includes a coaxial cable receptacle and provides a ground for the coaxial cable shield and conductor for a center conductor. The ground may be provided by a serrated washer and serrations that may be driven into the body panel when the fastener is secured. The center conductor is engaged by the fastener to conduct radio signals from the mast, through the mast base, to the fastener, and to the center conductor of the coaxial cable.
