Abstract: An inflatable device for shifting an animal's position in a chute, and specifically a bull in a bull riding event. The wedge includes an inflatable bladder with an opening to receive the inflatant from an inflatant source and one or more communicating passages transporting the inflatant to and from the inflatable bladder wherein inflation and deflation of the inflatable bladder controls the position of the animal in a chute.

Abstract: An energy management method and system for incorporation when constructing a building such that solar energy and waste heat is intercepted and diverted, in turn causing a reduction in the demand on the artificial heating and cooling unit.

Abstract: A high pressure mister cooling system having an electric fan, a high pressure pump mounted on the fan, an eccentric on the fan motor shaft, and mister nozzles mounted on the fan guard. A pump shaft is reciprocated by the eccentric when the fan is operated. A pump body includes a pump piston and bore, an inlet valve that opens when supply pressure exceeds 20 psi, a pump outlet valve that opens when pump pressure exceeds 120 pounds, and a pressure limiting valve that opens when pump pressure exceeds 1000 pounds. Water flows only when an inlet supply is attached and the fan is operating, and outlet pressure to the mister nozzles is controlled at about 1000 psi.
