Abstract: The instant invention describes an anti-biofouling structure for placement onto structures or surfaces that are exposed to aquatic environments. Embedded within the anti-biofouling structure are agents that can diffuse out of the structure and prevent the formation and/or accumulation of plant and animal species build-up that creates biofouling. The instant invention also describes a system for preventing biofouling of an object stored in an aquatic environment which includes the anti-biofouling structure, and a protective cover element constructed and arranged to fit various structures, such as boat propellers.

Abstract: The present invention provides a laser theodolite device and kit for converting a new or pre-existing theodolite into a laser theodolite. More specifically, in one embodiment, the laser theodolite device comprises a theodolite having a visible and/or reflective laser source integrally mounted within the theodolite telescope for generating a laser line along the centerline portion of the telescope line of sight. The kit for assembling a laser theodolite from a new or pre-existing theodolite includes a universally mountable bracket with a laser source secured thereto. The universal bracket is constructed and arranged to be mounted at a forward end of a theodolite telescope housing with the laser source being positioned at about a right angle with respect to the telescope centerline.

Abstract: A polyaxial wrench can apply torque to bolts, nuts and screws in close confines where leverage perpendicular to the axis of the bolt is restricted. The wrench has one end for mounting on the bolt, a shank and a sleeve. The shank extends longitudinally from the one end. The sleeve is rotatably mounted on the shank. The sleeve has connections for coupling an impact tool in several different angular configurations in relation to the longitudinal axis of the sleeve. Therefore, the impact tool can apply force vectors, of choice and dictated by the confines, polyaxially.
