Abstract: An X-ray inspection apparatus includes a transport unit configured to transport an article, an electromagnetic wave irradiation unit configured to irradiate the article with a first electromagnetic wave in a first energy band and a second electromagnetic wave in a second energy band, an electromagnetic wave sensor configured to detect the first electromagnetic wave and the second electromagnetic wave, and a control unit to which a detection result is input. The control unit is configured to generate a first transmission image based on a detection result of the first electromagnetic wave and a second transmission image based on a detection result of the second electromagnetic wave, to perform image processing including a subtraction process on the first transmission image and the second transmission image, and to determine whether or not a foreign material is included in the article on the basis of a difference image.

Abstract: A weighing machine includes a weighing unit that measures the weight of a product placed on a weighing table, a calculation unit that calculates the price of the product based on the weight of the product measured by the weighing unit, and a control unit that sets the price calculated by the calculation unit when the product is removed from the weighing table.

Abstract: An X-ray inspection apparatus includes a storage unit configured to store therein a plurality of image processing algorithms; an acquisition unit configured to acquire, as a reference transmission image, a transmission image obtained by transmitting electromagnetic waves through an article to which a foreign matter is attached or a synthesized transmission image; an evaluation unit configured to evaluate detection accuracy of the foreign matter for each image processing algorithm based on an evaluation image obtained by processing the reference transmission image with the image processing algorithms stored in the storage unit; and a setting unit configured to set at least one of the image processing algorithms as an image processing algorithm selected in advance based on evaluation in the evaluation unit.

Abstract: [Object] To provide an article discrimination system that can accurately infer the type of an article from an article image. [Solution] An article discrimination system includes an imager, an inference component, and a setting component. The imager captures an image of an article to acquire an article image. The inference component acquires first information which the inference component utilizes to infer the type of the article from the article image and, based on the first information acquired, infers one or plural types for the type of the article from among an article type group. The setting component sets at least one of types of articles that are available and types of articles that are not available among the article type group. The inference component preferentially infers, as the type of the article corresponding to the article image, the types of articles that are available over the types of articles that are not available.

Abstract: An X-ray inspection apparatus includes an X-ray source that radiates X-rays to a product, an X-ray detection unit that detects X-rays penetrating the product, and an uninterruptible power supply that supplies electric power during an electric power failure. The uninterruptible power supply is not electrically connected to the X-ray source.
