Abstract:

A guitar and violin hybrid instrument () comprising either a solid or hollow body (). The body () has an upper surface (), a lower surface (), an upper end (), a lower end (), a left half (), and a right half (). Located on the body's () lower section is a leg contour () that provides a comfortable leg support. On the lower surface () is an electronics cavity () for housing an electronics circuit (). Located on the body's () upper surface () is a plurality of magnetic pickups (G), control knobs for the operating the electronics circuit () and a bridge (). Located on the bridge's () upper surface () is a plurality of piezoelectric pickups (Y). A neck () extends from the body's upper end (). Attached to the neck's () upper surface () is a fretboard () on which a multiplicity of frets () are distributed. Located at the neck's () outer end () is a headstock () which has a plurality of tuning pegs () for adjusting the tension of a plurality of strings () that extend from the bridge (), across the body () and over the magnetic pickups (G) to the tuning pegs ().

Abstract:

A measurement targeting apparatus comprises a target body, a vessel with a channel, a fluid located within the channel in the vessel, and a pressurization system. The target body is selected from one of a photogrammetry target, a theodolite target, a construction ball, a touch probe target, a coordinating measurement machine probe target, a laser tracker target, and a laser projector target. The vessel has a centerline, has a substantially cylindrical portion capable of being received in a hole in a part, and is comprised of a material selected from steel, aluminum, and plastic. The vessel is capable of expanding when the fluid within the channel in the vessel is pressurized. The pressurization system is capable of pressurizing the fluid within the channel to cause the vessel to expand around the centerline.
