Abstract: A device that attaches to stringed instruments, preventing the bow from playing over the fingerboard, is disclosed. The device aids in developing proper bow technique, and only restricts movement of the bow over the fingerboard without restricting movement elsewhere between the fingerboard and the bridge.

Abstract: Imaging systems for visual works may be by implemented by a variety of systems, processes, and techniques. In one general implementation, an imaging system for a visual work may include side supports support configured to engage a support surface and support the imaging system thereon. The side supports may include tracks along their longitudinal axes. The system may also include a cross member configured to span between the side supports and engage their tracks. The system may also include a carriage adapted to move along a track of the cross member. The carriage may include a camera mount configured to receive, secure, and position a camera above the visual work to be imaged so that the camera images only a portion of the visual work at a time. The carriage may be moved to successive image acquisition locations at which an acquired image overlaps with the previous image.
