Devices and methods for inspecting containers for the presence of foreign matter include, in at least one embodiment, at least one sampling head, at least one pressure sensor, and a filter. The at least one sampling head is configured to introduce an amount of a first fluid into a container and to remove an amount of a second fluid from the container for inspection for the presence of foreign matter. The at least one pressure sensor is configured to measure a pressure of the second fluid upon removal of the second fluid from the container. The filter is arranged in the at least one sampling head and is configured to filter the second fluid.

Disclosed are a noise reduction box and a ventilation therapeutic device comprising the same. The noise reduction box comprises a shell (10) and a detection assembly, wherein the inside of the shell (10) defines a cavity; the shell (10) is provided with an air inlet (101) and an air outlet (102) which are in communication with the cavity; and the detection assembly is mounted on the shell (10) to detect the degree to which the inside of the cavity is dirty. The special detection assembly for detecting the degree to which the inside of the noise reduction box is dirty is mounted on the noise reduction box, so that the degree to which the inside of the noise reduction box is dirty can be clearly observed by means of the detection assembly, without it being necessary to disassemble the noise reduction box, and same is simple to operate and convenient for checking.

An inspection system for a drug container is provided to identify foreign matter, such as particles or fibers, within the drug container prior to filling with a drug. The system includes a camera device aligned with an axis of the drug container and captures a series of images of an interior surface of a sidewall of the drug container while the robot causes relative movement between the drug container and the camera device along a linear path. Atypical lighting, which improves contrast between particles and the background in images is employed to aid detection. A control circuit then processes the series of images to identify foreign matter within the drug container.

An apparatus for inspecting containers and in particular cans, having an illumination device which illuminates the can to be inspected and radiates radiation onto an inner base wall of the container, and having an image recording device which records at least one spatially resolved image of the inner base wall illuminated by the illumination device is provided. The apparatus has a first polarization device in a beam path between a light source of the illumination device and the inner base wall in such a way that the radiation reaching the inner base wall is polarized, wherein the illumination device being designed in such a way that a predominant proportion of the radiation irradiated into the container by the illumination device reaches the inner base wall.

Method for the optical inspection of containers, where the containers are transported with a conveyor as a container mass flow, where the containers are each captured with an optical inspection unit as first image data, and where the first image data is evaluated with an image processing unit for contamination and/or defects on the respective container, where the first image data of several containers is overlaid to form an overlay image, and where the overlay image is evaluated for the presence of points of contamination in a beam path of the optical inspection unit.

Method for optically inspecting containers, where the containers are transported to an inspection unit with an illumination unit and with a camera, where light emitted from a planar light-emitting surface of the illumination unit is transmitted or reflected via said containers, where the camera records in at least one camera image at least one of the respective containers and the light transmitted or reflected via them, where the light emitted from the light-emitting surface is locally encoded on the basis of a wavelength property and is recorded by the camera in such a way that different emission locations of the light-emitting surface can be distinguished from one another in the at least one camera image, and that the image processing unit evaluates the at least one camera image for location information of the emission locations, in order to distinguish the defects from the foreign objects.

An inspection station identifies defects such as artifacts (e.g., dust, hair, particles) in the sealing areas of sealed sterile packages. A multi-head optical scanner can include at least two fiber optic sensors each comprised of a bundle of optical fibers arranged into a linear face coupled to an image processing module and oriented towards a scanning area of sealed packages moving through a conveyance system. An image processing module can analyze input from the at least two fiber optic sensor arrangements to identify artifacts in the sealing areas of the sealed packages.

The disclosure relates to a method for optically inspecting containers, wherein the containers are transported to an inspection unit with an illumination unit and with a camera, wherein the illumination unit emits light from a flat light-emitting surface, wherein the light is transmitted or reflected via the containers, wherein the camera captures a respective at least one of the containers and the light transmitted or reflected via same in at least one camera image, and wherein the at least one camera image is analysed by an image processing unit for intensity information in order to identify foreign bodies and/or defects in the container.

A device and a method for inspecting containers for impurities and three-dimensional container structures comprising a radiation source. The radiation source is designed to emit radiation that radiates through a container to be examined. The device also comprises a detection element designed to detect the radiation that has been emitted by the radiation source and has radiated through the container. The device further comprises an evaluation element designed to evaluate the radiation detected by the detection element in terms of dirt and damage to the container. The radiation source has a plurality of spatially separated radiation zones. The radiation zones of the radiation source are designed to emit radiation of different wavelength ranges or of a different intensity.

An air treatment device includes a casing, a drain pan provided in the casing, a camera configured to capture an inner surface of the drain pan to obtain image data, and a lighting device configured to apply, to a photographing target of the camera, visible light having a maximum peak wavelength in a wavelength band from 400 nm to 500 nm.
