A method of generating a three dimensional surface profile of a food object is provided wherein a food object is exposed with a conical X-ray beam while the food object is conveyed. The attenuation of the X-rays after penetrating through the food object is detected, and the detection is performed using a plurality of sensors arranged below the food object. The plurality of sensors are positioned at predetermined angular positions in relation to the X-ray source. For each of the plurality of sensors, the detected attenuation is converted into a penetration length of the X-ray beam, and the penetration length indicates the length from where the X-ray beam enters and leaves the food object. Surface coordinates are sequentially determined using the penetration lengths and the angular positions as input data.

A fill level measurement device for determining a topology of a filling material surface is provided, including an antenna apparatus including an array of radiator elements and a rotatable mount configured to rotate the antenna apparatus about an axis that is in parallel with the array, such that a plurality of emission angles of the antenna apparatus are electronically and mechanically settable relative to the filling material surface without local overscanning occurring.

The invention relates to a method for ascertaining a net weight of a product in a product range, plurality of contiguous product ranges form a product chain and a total weight of the product chain is ascertained. The product chain is X-rayed to ascertain values that correspond to the radiation that penetrates a defined range of the product chain. The ascertained values are used to ascertain a total value for the entire product chain. A product range with a single product is selected by means of evaluation of the ascertained values. A value of the product range is formed from the ascertained values. A gross weight of the product range is ascertained therefrom. The net weight used for the single product is approximately the weight or the net weight is ascertained from the difference between the weight and a prescribed or ascertained weight of the product range without a product.

In some embodiments, systems, apparatuses and methods are provided herein useful to determine a weight of products on a product support structure. More specifically, the product support structure can be provided on a suspension system having one or more springs that can be monitored for compression to thereby determine a weight of products on the product support structure. In several embodiments, non-visible electromagnetic (EM) waves, can be directed at the spring and reflections of the non-visible EM waves can be received and analyzed to determine a compression of the spring.

An interferometric scattering microscope is adapted by performing spatial filtering of output light, which comprises both light scattered from a sample location and illuminating light reflected from the sample location, prior to detection of the output light. The spatial filtering passes the reflected illumination light but with a reduction in intensity that is greater within a predetermined numerical aperture than at larger numerical apertures. This enhances the imaging contrast for coherent illumination, particularly for objects that are weak scatterers.

In some examples, it is disclosed a computer-implemented method for inspecting cargo in an open-topped vehicle, including: obtaining an estimate of a volume of the cargo in the open-topped vehicle, based on data obtained from a top-observation device, the top-observation device being configured to observe a top surface of the cargo in the open-topped vehicle during a mutual movement of the open-topped vehicle and the top-observation device; determining an estimate of a mass of the cargo in the open-topped vehicle, based on the obtained volume estimate; comparing the determined mass estimate with a reference mass associated with the cargo in the open-topped vehicle; and determining whether the cargo in the open-topped vehicle is in conformity with the reference mass, based on the comparing.

In a calibration routine, a first set of X-ray recordings of at least one closed first reference package without content is produced, and a mass calibration signature is derived therefrom. A second set of X-ray recordings of at least one closed second reference package having a reference content is produced, and a reference signature is derived therefrom. From the reference signature and the mass calibration signature, a reference measurement value is derived via subtraction. The reference mass of the reference content is ascertained by weighing and assigned to the reference measurement value. In ongoing measurement operation, at least one set of measuring X-ray recordings of closed foil packages each having a content is produced and a measurement signature is derived therefrom. Herefrom, and from the mass calibration signature, measurement values for the individual closed foil packages are derived via subtraction, from which the masses of the contents are quantitatively determined.

An electromagnetic measuring device is presented for measuring one or more extensive properties of a product comprising a body, which is hollow inside, having walls made of a conductive material and defining an internal cavity, configured to receive the product and a coupling component, configured to create an electromagnetic field in the internal cavity and to receive said electromagnetic field disturbed by the product inside the internal cavity. The body has a loading opening made in one of said walls. The measuring device further includes a loading element and a movement device, the latter being capable of moving the loading element relative to the body and being configured to insert the loading element into the body through said loading opening from an external position, configured to receive the product, to an internal position, in which the product is in the internal cavity and it is positioned in a measuring position.
