Abstract: A hay bale spacer, the hay bale spacer configured with a riser support to provide an air gap between a tarp and an outer surface of a bale of hay, wherein said riser support is configured to be gripped, a side integral to said riser support, said side comprises a plurality of stakes extending from said side, said stakes configured to releasable affix thereto the outer surface of the bale of hay and that functions to create an environment with proper air circulation, prevent condensation, and to prevent mold growth within the hay bale, thus extending the storage expectancy of the bale.

Abstract: In a method of operating an air conditioning unit to reduce moisture varying operations, psychrometric chart data is accessed. In addition, a constraint is set on the relationship between the temperature of air supplied by the air conditioning unit and the relative humidity of the air supplied based upon information contained in the psychrometric chart data. The air conditioning unit is controlled based upon the constraint to thereby reduce moisture varying operations of the air conditioning unit.

Abstract: A multiple activity apparatus is disclosed for educational, therapeutic, or recreational use comprising three rectangular frame members joined at abutting ends in a triangular configuration having open triangular ends. The triangular configuration has a base and upwardly converging sides with a utility board mounted in each respective frame member. Each board has an exterior work surface so that a pair of upright work surfaces are selectively positionable for use at any one time. A method of utilizing visual teaching aids comprises the steps of assembling three utility panels each having a side surface useful as a teaching aid; disconnectably joining each of the three panels in juxtaposition forming at least two junctures between panels with the exterior surfaces positioned at an angle for use as teaching aids; and stacking the three boards generally flat forming an assembly for transport.

Abstract: A storage floor air vent may comprise at least two vent walls positioned in substantially parallel relation to thereby define a channel; a plurality of angular baffle members, each angular baffle member composed of two segments forming an apex therebetween; the plurality of angular baffle members positioned in between the at least two vent walls in a linear arrangement, with each apex facing upward proximal the top end of each of the at least two vent walls, and each angular baffle member is positioned a distance apart from the adjacent angular baffle member to thereby define an orifice between the segment ends of adjacent angular baffle members.
