  • Patent number: 11964781
    Abstract: A coupling unit is disclosed for detachable coupling two pars of a spacecraft, the coupling unit connecting the two parts of the spacecraft in a connected condition and the coupling unit distancing the two parts of the spacecraft, when the coupling unit is in detached condition. The coupling unit comprises a first element and a second element engaged to each other in connected condition, with the second element comprising a gas generator for generating gas under pressure to detach the first and the second element to bring them in the detached position, thereby distancing the first element and the second element from each other, and thus also the first part and the second part connected to the respective elements.

  • Patent number: 11948771
    Abstract: The disclosure relates to a method of determining an energy width of a charged particle beam, comprising the steps of providing a charged particle beam, directing said beam towards a specimen, and forming an energy-dispersed beam from a flux of charged particles transmitted through the specimen. As defined herein, the method comprises the steps of providing a slit element in a slit plane, and using said slit element for blocking a part of said energy-dispersed beam, as well as the step of modifying said energy-dispersed beam at the location of said slit plane in such a way that said energy dispersed beam is partially blocked at said slit element. The unblocked part of said energy-dispersed beam is imaged and an intensity gradient of said imaged energy-dispersed beam is determined, with which the energy width of the charged particle beam can be determined.

  • Patent number: 11930781
    Abstract: A milking system includes a milking device, a milk line, and a sampling and analysis device for the milk that includes a control unit, a tape mover to move and unwind a tape wound on a tape reel and with a base material with reagent pads, that detect a substance in the sample, and a dosing device to provide the sample onto a reagent pad, and a sensor to detect radiation from said reagent pad, and to analyse the detected radiation to indicate a presence or concentration of said substance. The reagent pad is facing downward during provision of the sample. In this way, the chance of excess liquid falling from the reagent, and possibly onto a camera, is reduced. Smaller reagent pads may be used, it reduces the chance of supplied liquid spilling over to a neighbouring reagent pad, the measures preventing this spilling may be limited, and it is easier to suck away excess fluid.

  • Patent number: 11925168
    Abstract: A milking system includes a milking device with a milking control, a milk line, and a sampling/analysis device. The milking control controls the milking based on said analysis. The sampling/analysis device includes a reagent carrier, including a tape with a first side with a reagent pad that detects the presence of a substance in the milk sample and a second side, a dosing device to provide a droplet of said sample onto the reagent pad, a source for emitting source radiation onto the reagent pad, and a sensor to detect response radiation emitted by the reagent pad, and to analyse the detected response radiation to indicate the presence or concentration of said substance. The first side faces away from the sensor during analysing by the sensor. By viewing “from below”, the observed reaction in the reagent is cleaner, and suffers less from artefacts, and the camera will stay cleaner.

  • Patent number: 11804357
    Abstract: An electron optical module for providing an off-axial electron beam with a tunable coma, according to the present disclosure includes a structure positioned downstream of an electron source and an electron lens assembly positioned between the structure and the electron source. The structure generates a decelerating electric field, and is positioned to prevent the passage of electrons along the optical axis of the electron lens assembly. The electron optical module further includes a micro-lens that is not positioned on the optical axis of the electron lens assembly and is configured to apply a lensing effect to an off-axial election beam. Aberrations applied to the off-axial electron beam by the micro-lens and the electron lens assembly combine so that a coma of the off-axial beam has a desired value in a downstream plane.
