Abstract: A vehicle flap (10) carried in a rearward position with respect to a vehicle tire (12) including a frame (14) with a pair of substantially parallel side walls (22) substantially perpendicular to and carried by a top member (18). The top member (18) is adapted to be carried by a vehicle (48). Vehicle flap (10) has a front side facing a tire (12) opposite a rear side. A roll base (34) extends outwardly toward vehicle tire (12) from near the bottom of flap (10). Vehicle mud flap (10) also has a plurality of arcuate, angularly-directed parallel vanes (24) which extend between the side walls (22) and extend downwardly from the front side to the rear side of the flap (10). The parallel vanes (24) form a plurality of openings (28) such that the parallel vanes (24) redirect any debris from the rotating vehicle tire (12) downwardly through the debris openings (28) while allowing the flow of air therethrough.

Abstract: A theft deterrent device (10) is provided for enclosures such as dwellings, motor vehicles and the like, having one or more entranceways. The device is adapted to be quickly and easily installed within such enclosures and is connected electrically with pre-existing electrical circuitry of the enclosure, causing the device to emit a noxious gas, upon unauthorized entry into the enclosure via one of the entranceways. The noxious gas renders the enclosure temporarily uninhabitable. The device may be activated or deactivated remotely from outside the enclosure. The device also includes other safety features to prevent accidental discharge of the noxious gas.
