Abstract: A method of monitoring a position of a movable member having a surface is provided. The method includes sensing an image of a portion of the surface of the movable member and identifying a stored image in a memory corresponding to the sensed image. The method further includes identifying a location of the movable member corresponding to the stored image. The stored image is replaced with the sensed image in the memory.

Abstract: A cylinder rod with wear-resistant surface markings is provided. The cylinder rod may include a rod substrate, a thermal-spray coating disposed on a surface of the substrate, and one or more surface markings disposed on the coating at predetermined locations along the length of the cylinder rod.

Abstract: Consistent with an aspect of the present disclosure, a method of locating a position of a movable member is provided. The movable member is movable along a path and has a surface with a plurality of markings provided thereon. The method includes sensing an image of a portion of the surface of the movable member, and calculating a position of the movable member based on the image. Further, the method includes determining whether the movable member is at a location corresponding to one of the plurality of markings, and eliminating an error associated with the position when the movable member is at the location corresponding to the one of the plurality of markings.

Abstract: A barcode on a material includes at least one line having a length and a width. The line may be formed by markings on the material, and the markings may form a first row and a second row. The first row may be adjacent to the second row. The markings also forming a first column and a second column, with the first column being adjacent to the second column. The markings of the first row are offset from the markings of the second row.

Abstract: A method and apparatus for determining the position of a rod member of a cylinder assembly are provided. The cylinder assembly may include a cylinder body, a gland member, a sensor mount, a rod member, and a position sensor attached to the sensor mount. The cylinder body may have a first mounting portion disposed thereon. The gland member may be disposed within a gland opening of the cylinder body. The sensor mount may have a second mounting portion disposed thereon and may be attached to the cylinder body via a coupling engagement between the second mounting portion of the sensor mount and the first mounting portion of the cylinder body. The rod member may be slidably arranged within rod openings of the sensor mount and the gland member and may extend into a longitudinal cylinder chamber of the cylinder body.
