Abstract: The current invention relates to a piezochromic device wherein said device exhibits a reversible change in appearance initialed by an external applied force and then reverts back to its original appearance over a set relaxation time when the external force is removed. In one embodiment, a device comprising a transparent or semi-transparent cover layer and a magnetic layer, wherein between the cover layer and the magnetic layer is a liquid medium containing magnetically alignable pigments.

Abstract: A method and apparatus permitting a single operator to drive elongated rods, e.g. tent stakes, into the ground for securing lines, ropes, cables and the like. The apparatus is a holder for the rod or stake that is fixed to the driving end of a pneumatic hammer. A longitudinal slot in the apparatus permits positioning of the rod so that the operator can raise the pneumatic hammer and rod into a generally vertical position and by activating the pneumatic hammer drive the rod into a fixed position. Thereafter the pneumatic hammer and holder can be readily removed from the driven rod.

Abstract: Method and apparatus for single handed erection of a tent pole having a tent supporting end and a ground end the ground end supported in a carrier pulled along the ground to position the ground end of the pole beneath the portion of the tent contacting the tent supporting end of the tent pole. The apparatus uses a cable connected to a receptacle fitted over the ground end of the tent pole with the cable wound around a cable drum of a winch, the receptacle supported by wheels, rollers or skids to move along the ground as the cable is wound onto the drum. A motorized winch and remote control place the user outside the tent as it is erected.

Abstract: Counter for stacked articles, e.g., folding chairs. A wheel having a notched peripheral surface is connected to a count indicator. The wheel and counter interact so that when a user places the wheel with a notch at the lowermost of the stacked articles and the wheel is rotated by moving the counter vertically against the stack, each time a successive notch is moved the count indicator registers the next highest number.

Abstract: A vehicular antenna system uses a plurality of vehicle windshield wipers. Each wiper is configured to act as an antenna receiving element. The wipers may be configured to act as receiving elements by using a conductive wiper housing and/or a conductive spring. Insulators are positioned to electrically isolate the antenna receiving elements from vehicular ground. In one embodiment, an insulating bushing is positioned within a windshield wiper housing aperture so that the entire wiper is isolated from a wiper shaft.
