Abstract: The present disclosure relates to end milling methods for making microstructures, a tool comprising such microstructures, the microstructures, and replications thereof, where the microstructures are part of a structured surface configured as a security article. Some of the microstructures are configured differently from others to define an optically detectable indicia in the structured surface. Microstructures in a first group may for example differ from microstructures in a second group in terms of one or more of size, orientation, cube corner type, and dihedral angle value(s), to define the indicia or a portion thereof. The microstructures may comprise full or truncated cube corner elements, and the article may be a retroreflective sheeting.

Abstract: A new technique for making cube corner elements that involves end milling is used in the fabrication of cube corner elements having non-orthogonal dihedral angles and dihedral angle errors, and arrays of such cube corner elements. A given optical face of a cube corner element may be a compound face with two constituent faces. In some cases, the constituent faces may be parallel and coplanar such that a given dihedral angle error pertains to the entire optical face, while in other cases, the two constituent faces may not be parallel, and may be associated with different dihedral angle errors.

Abstract: A system for improving inspection systems is provided. The system generally includes a camera in communication with a processor. The camera is configured to capture an image for inspection of an object A to be inspected. The camera transfers the image to the processor for comparison with a reference image. If the comparison is not within a predetermined range, then the camera settings are adjusted and a new image is taken until the current image matches the reference image. Alternatively, or in addition to, the system is capable of learning based on a plurality of data and creating a model image for comparison prior to capturing the first image.

Abstract: Cube corner articles such as retroreflective sheeting utilize multiple cube corner arrays in a tiled configuration, each tile containing one array of canted cube corner elements. The tiles may be long and narrow, and the array in each of at least two or three adjacent tiles, or even in every tile, may include at least one lengthwise groove that is parallel to an edge of the tile and parallel to a fixed in-plane axis. Each tile may have a width that is narrow (e.g. 0.2 to 5 mm), and equal to an integer multiple of a lengthwise groove pitch to avoid or reduce ineffective fragmented cube corners along the tile edge. Each array may have a plane of cant and a primary plane of entrance angularity, and the primary planes of entrance angularity for the multiple tiles may be more evenly distributed in azimuthal angle than the planes of cant.

Abstract: The present disclosure relates to end milling methods for making microstructures, and articles containing such microstructures. The end milling process comprises rotating an end mill (1410r) around an axis of rotation (1409) and translating the rotating end mill (1410r) in a working surface (1407) to form a first recess (1420) such that end mill (1410r) moves along an inclined path (1411) relative to the working surface (1409), or to a reference plane along which the working surface (1407) extends. The method forms flat faces (1441a, 1441b) that meet along a rounded edge (1451), the edge (1451) being inclined to the reference plane. Both truncated cube corner elements (see for instance FIGS. 47 and 48) and full cube corner elements (see for instance FIG. 56A) can be made in a substrate (4705, 4805, 5605) by forming at least part of an optical face of the cube corner element (4780, 4880, 5680) by cutting the substrate (4705, 4805, 5605) with a rotating end mill (1410r).

Abstract: A footwear construction and related method of manufacture are provided. The footwear can include an upper with a closed liner disposed in an interior of the upper, a flexible Strobel board closing the bottom of the upper and an outsole joined with the upper. The method can include providing an upper having a liner secured thereto, closing an open bottom of the liner with a bottom closure without closing an open bottom of the upper, Strobel stitching a flexible Strobel board to the upper to close the upper bottom, placing the upper with the lining and Strobel board secured thereto on a last and joining an outsole with the upper. The liner bottom closure and Strobel board can be of a thickness and flexibility so that a wearer can perceive movement of the outsole underfoot. Accordingly, the footwear can provide enhanced proprioceptive feedback from a surface being traversed.
