Abstract: An inflatable boat comprises an inflatable body, at least one inflatable wing member and at least one holding device. The inflatable wing member is attached onto the inflatable body, while the holding device is connected to the inflatable wing member. Furthermore, the inflatable wing member has a rowing plate on which at least one check valve is provided. The inflatable boat can go ahead on a surface of water when the inflatable wing member is pulled by the holding device to paddle the water.

Abstract: A multishaft combination lock includes a lock body, an alignment sleeve, and a detachable pin. The alignment sleeve has a hole and is rotatably coupled to the lock body to provide access into the lock body. The alignment sleeve has an angled cutout at a first end, with the alignment of the cutout being adjusted by rotating the alignment sleeve. The detachable pin has a floating bushing that can be misaligned with the principle axis of the detachable pin. To lock the multishaft combination lock, the lock body is fitted to the detachable pin through the hole of the alignment sleeve with the floating bushing misaligned with the angled cutout. When the detachable pin is fully inserted into the lock body, the floating bushing is positioned beyond the end of the alignment sleeve within the lock body and becomes misaligned or offset with the alignment sleeve. To unlock the lock, the alignment sleeve is rotated so that the angled cutout is aligned with the floating bushing of the detachable pin.

Abstract: A method and apparatus for modifying an image data signal has a serial channel for obtaining a desired number of current M-bit patterns from the image data. Unique bit patterns are recognized in the current bit patterns, and new bit patterns are generated, each being specific to the detected unique bit pattern. The current and new bit patterns are combined in a predetermined manner to modify the image data as desired. For example, if the unique bit patterns are recognized as dark images on a leading edge of an image, the new bit patterns are generated and combined with the current bit patterns to lighten the image, particularly at the leading edge to improve stripping of the print media on which the image is printed from a fuser roll of the printer.
