Abstract: An apparatus is configured to monitor a plurality of layers of a battery layer stack during manufacturing. The apparatus includes at least one X-ray source configured to generate X-rays with X-ray energies that exhibit contrast of transmission through the plurality of layers of the battery layer stack. The at least one X-ray source is configured to face a first side of the battery layer stack. The apparatus further includes at least one sensor configured to detect the X-rays transmitted through the plurality of layers. The at least one sensor is configured to face a second side of the battery layer stack.

Abstract: The present disclosure provides techniques for monitoring transaction data. A first symbol is a symbol is assigned, at a first point in time, to a user device, where, when a user of the user device inputs an item, the user device outputs the symbol. The symbol is then detected, via one or more image capture devices, at one or more moments in time, and a number of times that the symbol was detected is determined. At a second point in time subsequent to the first point in time, a number of items associated with the user is determined. An audit of the uses is initiated based on determining that a difference between the number of times and the number of items exceeds a threshold maximum difference.

Abstract: Described herein is an x-ray tube assembly that includes: a housing that encloses an inner volume; a movable divider within the inner volume, the movable divider dividing the inner volume into a first volume and a second volume; an x-ray tube within the first volume; the first volume between the housing and the x-ray tube filled with an insulating fluid; and the second volume filled with a compressible gas.
