The systems and methods include the capability to produce a video of the surfaces, the capability to analyze individual frames of the video to obtain surface texture feature data for areas of the surfaces depicted in each of the individual frames, the capability to analyze the surface texture feature data to detect surface texture features in the areas of the surfaces depicted in each of the individual frames, the capability of tracking the motion of the detected surface texture features in the individual frames to produce tracking data, and the capability of using the tracking data to filter non-crack surface texture features from the detected surface texture features in the individual frames.

Push-cables and associated apparatus and systems are disclosed. In one embodiment, a push-cable assembly for use with a pipe inspection system may include a push-cable element having a proximal end and a distal end, with a spring assembly having varying flexibility coupled to or near the distal end. The spring assembly may include an outer coiled spring having a proximal and a distal end, and an inner coiled spring nested at least partially within the outer coiled spring. A camera head and/or other elements such as a cutting or jetting apparatus may be coupled at or near the distal end.

The present invention relates to a test film for detecting surface particles in a clean room in order to prevent inferior products by measuring the contamination level of the clean room using the surface particles. The present invention provides a test film for detecting surface particles in a cleanroom, the test film comprising a substrate which has a predetermined thickness and is formed of a transparent synthetic resin material; a first adhesive layer which is formed at one side of the substrate and collects the surface particles; a release film which is adhered to the first adhesive layer and is separated from the first adhesive layer when the surface particles are collected; a second adhesive layer which is formed at the other side of the substrate; and a protective film which is adhered to the second adhesive layer so as to protect the substrate and has gradations indicated thereon. According to the present invention, there is an effect in that it is possible to easily and quickly check whether or not a clean room is contaminated by collecting, on the adhesive layer-applied surface of a substrate to which an adhesive is applied, surface particles adhered to an object to be measured, and then measuring the number, size, distribution, etc. of the surface particles with the naked eye or using instruments such as a light, a magnifier, a microscope, or the like.

An apparatus for inspecting lenses includes an inspection system including an open cuvette, a communicatively coupled CT measurement device, and a user interface communicatively coupled to the inspection system. According to one embodiment, the lens inspection system provides a single instrument for inspecting the quality of a lens, thereby minimizing the transference of the lens from one inspection component to another.

A method of inspecting two or more sides of an object is provided. The method includes generating one set of image data of two or more sides of the object, such as by using spherical mirror segments that project all sides of the object onto a single image and generating an X by Y array of image data of the single image. The projection of the image data is then compensated for, such as by identifying inspection processes to locate defects of the object in the projected image data or by converting the image data from the projected inspection coordinates to Cartesian coordinates. Predetermined inspection processes are then performed on the compensated image data, such as by using the inspection processes that are optimized for use with the projected image data or by converting the projected image data into a Cartesian format and using Cartesian image data inspection processes.

An imaging device includes multiple sensor pixels that are arranged in a predetermined direction, each sensor pixel having multiple sensor pixel borders defining an outer edge part of the sensor pixel, among which at least one of a pair of sensor pixel borders that are opposed in the arrangement direction is oblique to a passage direction of a defect image that is vertical to the predetermined direction. This can provide an inspection tool enabling high sensitivity inspection and/or having improved detection reproducibility of a defect.

The present invention comprises a surface to maximize the viewing of an impression in a vehicle body. This may comprise a fabric which has at least one dark colored stripe parallel to at least one light colored stripe; a compressible frame across which the said fabric is affixed, where when the frame is uncompressed the fabric is stretched taut across the frame and where the frame is compressed the fabric is slack across the frame; and a handle on the frame where a user can hold the frame and not interfere with the fabric affixed to said frame. When a user is holding the handle of the frame at an angle between 0° and 180°, the user can reflect radiant energy through said fabric onto the vehicle body and create a whorl reflection pattern on the impression to maximize viewing of said impression by the user.

A cosmetic testing device for electronic devices that uses the electronic device's own camera to take photographs of the electronic device in order to determine its cosmetic condition.

A blocked lens assembly suitable for on-block processing and cleaning includes a blocked lens and a sealing member disposed on at least a portion of an edge and/or surface defined by the blocked lens. The blocked lens further includes a lens blank having a front surface and a back surface, a lens blocking piece to hold the lens blank while processing the back surface of the lens blank, and an adhesive layer, disposed between the front surface of the lens blank and the lens blocking piece, to affix the lens blank to the lens blocking piece. The sealing member protects the blocked lens so as to facilitate cleaning of the blocked lens while the lens blocking piece is affixed to the front surface of the lens blank
