Abstract: One aspect of the present disclosure include a method and system for providing an interactive virtual reality simulation for virtual reality training. A headset, controllers, and/or one or more sensors communicate with a processor to display the interactive virtual reality simulation on a user display within the headset. The interactive virtual reality training for use in facilitating virtually reality simulations including a microscope simulation, a bacteria streaking simulation, and/or a visually inspecting containers simulation.

Abstract: A hand truck having improvements made to simplify and make more ergonomically use of a hand truck by an operator. The hand truck provided having adjustable handles and a bottom portion having adjustable stair climbers with improved feature and an improved wheel and brake assembly have an axle-less wheel assembly and an improved caliper mounting system. These features are discussed in detail in the forgoing.

Abstract: A pallet mover intended to lift and move pallets. The pallet mover including a first deck, a second deck and a locking mechanism. In one embodiment, the locking mechanism includes three crescent shaped brackets with elongated slots therein. The two outermost brackets pivot to lift the first deck to raised position, and position the handle upright and at the 45-degree angles (for pushing or pulling the unit). The center bracket includes an aperture to receive the spring-loaded locking pin which locks the deck and handle portion in either the up or down position. The present pallet mover is manually driven thus having increased maneuverability and lower manufacturing cost.
