Abstract:

Uniaxially Oriented Articles Having Structured Surface A process for uniaxially stretching films is having a structured surface comprising a geometric feature is described. The process provides a film in which the cross sectional shape of the feature after stretching is substantially identical to the cross sectional shape of the feature prior to stretching. Structured surface articles are also described. The articles have substantially the same uniaxial orientation throughout the film, including the geometric structure. Uniaxially oriented articles having structured surfaces are described. The articles have dimensional relationships as follows: the (a) ratio of the thickness of the body (Z′) to the height of the geometric feature (P′) is at least about 2; or (b) the ratio of body thickness to feature height (Z′:P′) is at least about 1 and the ratio of feature height to feature separation (P′:FS′) is at least about 1; or (c) the ratio of body thickness to feature height (Z′:P′) is at least about 1 and the ratio of feature base width to feature separation (BW′:FS′) is at least about 1; or (d) the ratio of body thickness to feature base width (Z′:BW′) is at least about 3; or (e) the ratio of body thickness to feature base width (Z′:BW′) is at least about 1 and the ratio of feature height to feature separation (P′:FS′) is at least about 1; or (f) the ratio of body thickness to feature base width (Z′:BW′) is at least about 1 and the ratio of feature base width to feature separation (BW′:FS′) is at least about 1; or (g) the ratio of feature base width to feature top width (BW′:TW′) is at least about 2 and the ratio of feature base width to feature separation (BW′:FS′) is at least about 1.

US Classification:

428156000

Abstract:

An article, such as a film, comprising a body portion and a surface portion is provided. The body portion has (i) a first and a second surface, and (ii) first and second in-plane axes that are orthogonal with respect to each other and a third axis that is mutually orthogonal to the first and second in-plane axis in a thickness direction of the body. The surface portion comprises a linear geometric feature disposed on the first surface of the body in a direction substantially parallel to the first in-plane axis of the polymeric body. The article has (i) a first index of refraction (n) along the first in-plane axis, (ii) a second index of refraction (n) along the second in-plane axis, and (iii) a third index of refraction (n) along the third axis, wherein nand nare substantially the same but substantially different from n; and wherein the uniaxially oriented polymeric film has a relative birefringence of 0.3 or less and wherein the ratio of the thickness of the body to the height of the geometric feature is at least 2.

International Classification:

G01N 21/95
H04N 7/18

US Classification:

348 92

Abstract:

An inspection device comprises a camera assembly including an objective lens that captures and collimates light associated with an object being inspected, an image forming lens that forms an image of the object based on the collimated light, and a camera that renders the image. The camera assembly defines a focal point distance from the objective lens that defines a focal point of the camera assembly. The inspection device comprises an optical sensor positioned to detect an actual distance between the objective lens and the object, an actuator that controls positioning of the objective lens to control the actual distance between the objective lens and the object, and a control unit that receives signals from the optical sensor indicative of the actual distance. Control signals from the control unit can control the actuator to adjust the actual distance such that the actual distance substantially equals the focal point distance.

US Classification:

382160

Abstract:

A computerized rating tool is described that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. The rating tool provides mechanisms for visualizing the training images in an intuitive and configurable fashion, including clustering and ordering the training images. In some embodiments, the rating tool provides an easy-to-use interface for exploring multiple types of defects represented in the data and efficiently assigning expert ratings. In other embodiments, the computer automatically assigns ratings (i.e., labels) to the individual clusters containing the large collection of digital images representing the samples. In addition, the computerized tool has capabilities ideal for labeling very large datasets, including the ability to automatically identify and select a most relevant subset of the images for a defect and to automatically propagate labels from this subset to the remaining images without requiring further user interaction.

Abstract:

A system is described for detecting the presence of non-uniformity patterns and providing output indicative of a severity of each type of non-uniformity pattern. The system includes a computerized rating tool that assists a user in efficiently and consistently assigning expert ratings (i.e., labels) to a large collection of training images representing samples of a given product. In addition, the rating software develops a model that allows a computerized inspection system to detect the presence of non-uniformity patterns in a manufactured web material in real time and provide output indicative of a severity level of each pattern on a continuous scale. The system also includes algorithmic and hardware approaches to significantly that increase the throughput of the inspection system.
