Abstract: A system and apparatus for inserting a watermark into a compiled computer program selectively replaces specified optimizations by non-optimized code to encode bit values of the watermark. The watermark is read by decoding the executable code and assigning the decoded bit values, determined by the presence or absence of optimized code, to bit positions in a signature.

Abstract: On the seat of a motorcycle, a strap, typically located between the front and rear seats of the motorcycle seat, may be grasped by the rear seat passenger. A cover for the entire seat is stowed in a pocket in the strap. The pocket is openable to permit deployment of the cover over the seat and the cover may be re-stowed within the pocket in the strap. Closure elements close the pocket of the strap.

Abstract: A sock having a pocket supported inside its leg portion. A first vertical slit opening in the sock provides access to the pocket within the sock and that opening is closed by a zipper. The pocket has a corresponding slit opening in one wall and the margins of the slit opening in the pocket are stitched along the margins of the two tracks of the zipper closure at the opposite sides of the slit opening in the sock. That is the only securement of the pocket to the sock, avoiding additional stitching or fastening of the pocket to the leg portion of the sock. The pocket is large enough and wide enough to hold needed objects.
