Abstract: Disclosed is an impact-responsive vest having a piezoelectric layer sandwiched between other layers and connected by wire leads to a control module. The control module includes a programmable read-only memory having parameters identifying, through the amplitude of a signal impact, forces produced by paint ball impacts which are compared with impact signals from the vest. When a match is found, the compare circuit sends a signal to an audible alarm to alert the wearer that he or she has been hit by a paint ball. The control module is compact and is worn by the vest-user. Also disclosed is a remote reset module to provide a reset signal to the control module once the alarm has been activated.

Abstract: A running board construction for mounting to a vehicle includes an elongate deck and at least one bracket extending beneath and transverse to the deck, the bracket being attachable to the frame of the vehicle for mounting the running board to the vehicle. A single channel is formed integrally with the underside of the deck in substantially the center of the deck and a pair of flanges are also formed integrally with the deck and spaced to both sides of the channel. The channel slidingly receives a bolt for fastening the bracket to the underside of the deck and the flanges extend to a lower elevation than the channel, such that when the bolt is tightened, the bracket is bowed beneath the deck.
