Abstract: A locatable object includes a microprocessor for operating the object, and a memory for storing at least a first position and a second position. The locatable object also includes an instrument recovery system integrated into the object. The instrument recovery system further includes a receiver for determining the location of an object, and a communications device for communicating at least the second position to another system.

Abstract: A mobile tool station and worktable is disclosed. The mobile worktable is supported on wheels that can be locked to prevent movement, or unlocked to allow free movement of the workbench. The worktable allows a person to assemble, test or build items on top of the table. The table also includes a tool station for the person to locate tools or a tool case that can be removed from the worktable. The tool station is configured on a gurney type configuration where an additional set of wheels can be located at one or both ends of the table to allow the additional set of wheels to be placed in the bed of a truck and the work table collapsed to allow a single person to place or remove the table in the back of a truck.

Abstract: A sound imaging system preferably including two enclosures each comprising a truncated conical base unit and a truncated conical upper unit supported above and spaced apart from of the base unit, and containing a bass driver and composite midrange and high frequency drivers. The bass driver is oriented horizontally at the top of the base unit, and the sound energy produced therefrom is reflected by a conically shaped acoustic lens or defector depending from within the interior of the upper unit directly above the bass driver, such that the sound energy is reflected downwardly along and between the spaced apart truncated conical walls of the upper unit and base unit and emanates radially therefrom in all directions. The composite midrange and high frequency drivers are supported at the top of the upper unit on a crown structure having a plurality of vertical legs defining a platform oriented approximately 20.degree. relative to horizontal.
