Abstract: The Bass Clarinet Body Strap allows a bass clarinetist to attach their body to their bass clarinet and its loop attachment point on the instrument situated above the bass clarinet thumb rest. A wide strap has one end that goes in front of the player approximately at chest level, and extends over one shoulder, across the back, down around the other side of their body coming out below the other arm, and around the front of the player's body where the two wide strap ends meet. One end of the wide strap has a lace attached that is manually passed through an opening in the other end of the wide strap and is affixed to the closed loop of a hook. This hook is then affixed to the bass clarinet loop attachment point above the thumb rest. A buckle on the strap allows for size adjustment.

Abstract: There is provided a system for authorizing a sale of a product at a point of sale. A database has an activation key table.
