Abstract: A foldable stringed instrument having an actuator system that serves to selectively loosen and tighten the strings to fold and unfold the stringed instrument for storage/travel and play, respectively, as well as a mid-neck hinge to enable symmetrical folding of the stringed instrument. Optional cavities may be provided in the body of the stringed instrument for weight reduction and/or receiving sustain modules configured to modify the sustain of the stringed instrument depending upon the weight and/or material properties of the sustain modules.

Abstract: An actuator system for a foldable stringed instrument (for example, a travel guitar). The actuator system serves two primary function: 1) to selectively retract and extend a ram rod used to unlock and lock a mid-neck hinge of the foldable stringed instrument.

Abstract: A pitch changer system for a string musical instrument, including a lever assembly, a rotating saddle assembly, a swing plate, and a lever tensioning assembly. Applying force to move the lever in a first direction forces a bell crank matingly coupled to the lever into rotation such that a coupling system of the lever tensioning assembly causes the swing plate to force a rotating saddle of the rotating saddle assembly into rotation to elongate and thereby temporarily change the pitch of a string coupled to the rotating saddle.

Abstract: A graphical user interface (“GUI”) defined cursor displacement tool is provided for use on a touch-sensitive display or screen of a computing system. The GUI defined cursor displacement tool includes a first portion defining a cursor control handle, a second portion defining a cursor tip, and an offset visibly separating the cursor control handle and the cursor tip. The control handle is operable to synchronously move about the touch-sensitive screen with the cursor tip, at the offset from the cursor tip, to interact with screen graphics displayed on the touch-sensitive screen.
