Abstract: A protection circuit senses when one supply circuit in a group is activating to deliver current to a circuit component and issues firing signals to simultaneously activate other supply circuits in the group. The supply circuits may deliver large currents and high power. The protection circuit may prevent damage to a system that might otherwise occur if one supply circuit in the group activates in isolation.

Abstract: The present invention provides a novel and improved animal sprayer for use in cooling livestock and other animals in different hot or dry environments, and methods of using the same. Embodiments of the novel animal sprayers may include a valve which does not require constant electric current to remain open during a spraying session, extending system battery life. The valves may also be self-cleaning, less likely to leak, and easily adjusted to control flow rate, reducing both water use and labor costs in monitoring and repairing the animal sprayer.

Abstract: A height adjustable work surface is described that may be utilized as a standalone desk or table, or integrated with a larger work surface to provide selective height adjustability to only a portion of a work surface. The height adjustable work surface preferably utilizes a modular trapezoidal frame structure, including trapezoid tube weldments, corner castings and machined hardened connector pins. The lift mechanism preferably includes parallelogram linkages, pneumatic gas cylinders, sliding brake bar mechanism and brake release handles to provide height adjustment functionality.

Abstract: A drawer assembly for a work vehicle includes a drawer configured to slide between a closed position that blocks access to an interior of the drawer and an open position that facilitates access to the interior of the drawer. The drawer includes a first exterior body panel of the work vehicle, the drawer is positioned such that a second exterior body panel of the work vehicle at least partially surrounds the first exterior body panel while the drawer is in the closed position, and the first exterior body panel is configured to substantially align with the second exterior body panel while the drawer is in the closed position.

Abstract: A tabletop positioning and locking assembly is described for use with a modular trapezoidal table frame structure that utilizes trapezoid tube weldments. The positioning and locking assembly automatically positions the tabletop on the trapezoidal table frame at the exact desired location in relation to the frame, and also securely locks the tabletop down onto the table frame without the need for hardware or tools.

Abstract: An off-road vehicle includes an air intake system that comprises an opening that, in operation, receives air, and an exhaust system that includes an exhaust stack positioned in the opening of the air intake system.
