An inspection device which is compatible with in-line inspection of containers and reliably determines the presence or not of a defect of a container, has a lighting system arranged above an installation zone and being capable of providing an incident light beam, an image sensor connected to an image-analysis unit, and an optical system with a first primary reflection surface arranged above the installation zone and interposed between the installation zone and the sensor for forming on the sensor an image of a container ring surface to be inspected. Also included is a second primary reflection surface in the upstream field of vision of the sensor to reflect light beams, directly or indirectly in the direction of the sensor. The first and second primary reflection surfaces determine first and second portions of a downstream field of vision, which overlap in the inspection zone.

A leather inspection apparatus is provided for detecting inconsistencies on both upper and lower surfaces of a hide. It includes a first camera assembly movably coupled to a support frame and capable of movement along the upper surface of the hide and a second camera assembly movably coupled to the support frame and capable of movement along the lower surface of the hide. A computing device is coupled to the first camera assembly and the second camera assembly, such that the first camera assembly detects the locations of inconsistencies in the upper surface of the hide and the second camera assembly detects the locations of inconsistencies in the lower surface of the hide. The computing device digitally stores the locations of the inconsistencies of the upper surface of the hide and the locations of the inconsistencies of the lower surface of the hide.

A target sample to be chemically analyzed is received at a microfluidic device which is part of an analysis card. The microfluidic device includes at least one input layer configured to receive the target sample, at least one intermediary layer, and at least one readout layer configured to present one or more color attributes at one or more readout regions in response to one or more colorimetric reactions to the target sample. An image of the readout layer of the microfluidic device is obtained. A calibration file that corresponds to the analysis card is obtained. The calibration file includes a calibrated model of at least one color attribute based on data from at least one known chemical attribute of at least one standard sample processed by a calibration card. A data processing function is executed on the obtained image by comparing the one or more color attributes at the one or more readout regions to the calibrated model of the at least one color attribute to determine at least one chemical attribute of the target sample.

A light-sheet fluorescence microscope has a laser producing a light beam, two objective lenses arranged with their optical axes in different directions to provide different views, a scanning mirror configured to direct the light beam into distinct portions of an optical path, a beam combining/separating component configured to direct the light beam in the distinct portions of the optical path alternately into each of the two objective lenses and to combine detection light from the two objective lenses into the distinct portions of the optical path, a dichroic mirror that separates the light beam from detection light, and a camera sensor focused simultaneously on the focal planes of said two objective lenses. Embodiments may also include an adaptive optics or fixed corrective element.

A method of determining a presence of a wire-edge at the site of an internal edge of a ring surface of a ring of a container includes lighting of the ring surface of the container from above using a radial light beam at 360 and observing the ring surface according to a peripheral observation field. A first principal circle is formed in a first image zone. At least one secondary arc of a circle concentric to the first so-called principal circle, and radially offset relative to the latter is also formed in the first image zone. The first so-called principal circle and any first secondary arc of a circle are searched using the first image zone. A device for executing the determining method is provided along with a line including the device.

An optical inspection system for detecting sub-micron features on a sample component. The system may have a controller, a camera responsive to the controller for capturing images, an objective lens able to capture submicron scale features on the sample component, and a pulsed light source. The pulsed light source may be used to generate light pulses. The camera may be controlled to acquire images, using the objective lens, only while the pulsed light source is providing light pulses illuminating a portion of the sample component. Relative movement between the sample component and the objective lens is provided to enable at least one of a desired subportion or an entirety of the sample component to be scanned with the camera.

A high-speed method and system for inspecting and sorting a stream of unidentified mixed parts are provided. The system includes a pair of inspection stations each of which includes a vision-based robotic subsystem including a robot configured to pick up a self-supporting part and place the part on a fixtureless rotary stage. A second subsystem optically measures a profile and features of the part during part rotation. A processor is operable to compare the profile and features of the part with the profile and corresponding features of stored templates to identify a matching template. A mechanism including a part sorter directs unidentified parts and parts having an unacceptable geometric dimension or defect to a reject part area and directs identified parts having acceptable geometrical dimensions and no significant defects to good part areas.

A process and an apparatus for measuring an amount of dissolved air which may be dispersed or entrained in liquids.

A method, apparatus, and system for inspecting a fuselage of an aircraft. A rail is positioned within an interior portion of the fuselage of the aircraft such that the rail extends through the interior portion of the fuselage. An inspection device is attached to the rail. The inspection device moves along the rail and the position of the rail enables the inspection device to inspect the interior portion. Video data is sent to a computer system over a wireless communications link between the inspection device and the computer system. The video data is displayed on a display system for the computer system. Inspection operations are performed in the interior portion of the fuselage with the inspection device attached to the rail when a group of commands to perform the inspection operations are received from the computer system over a wireless communications link between the inspection device and the computer system.
