  • Patent number: 12235621
    Abstract: A method for aligning a workpiece in a working space of a machine tool having a numerical control system uses a probe. 3D models of the working space, probe, and workpiece are virtually displayed. The workpiece is positioned in the working space and the virtual workpiece is positioned in the virtual working space so that there is an initial coincidence between positions thereof. The probe is manually positioned relative to the workpiece, wherein a planned probing point and probing direction are selected based on a minimum distance of the virtual probe from the virtual workpiece, and are displayed. Enabling of the probing is based on quality of the planned probing point, and, when enabled, a probing operation is triggered, and coordinates of a probing point are determined. The position of the workpiece is recalculated using these coordinates, and the position of the virtual workpiece is updated.

  • Publication number: 20250027867
    Abstract: Presented herein are systems and methods for analyzing images of target particles that are bound to a surface of a substrate. In certain embodiments, systems and method described herein utilize techniques that remove background noise from interferometric images of small particles, allowing for increased accuracy in detection and/or characterization of individual particles. Such techniques, as described herein, may allow individual particles having sizes below about 100 nm (e.g., below about 50 nm; e.g., down to 20 nm) to be accurately detected within images, and, among other things, their characteristic sizes measured utilizing, e.g., their contrast.

  • Publication number: 20250021087
    Abstract: Example methods and systems relate to the modeling of production processes to include intermediate products. An enterprise resource planning (ERP) system receives user input to define an intermediate product, and generates a master data record for the intermediate product. The ERP system further receives user input to include the intermediate product in a production model within the ERP system. The production model is associated with a real-world production process. The production model is updated based on the master data record to integrate the intermediate product into a sequence of activities. The sequence of activities comprises a first activity that produces the intermediate product and a second activity that consumes the intermediate product. The ERP system executes a production order based on the production model. Execution of the production order includes tracking state information of the intermediate product within the ERP system.

  • Patent number: 10741373
    Abstract: The invention relates to a method for operating an ion gate having a first, a second, and a third electrode which are arranged one after the other in an intended drifting direction of ions to be influenced by the ion gate, in such a way that the second electrode is arranged after the first electrode and the third electrode is arranged after the second electrode in the drift direction. The ion gate can be switched between a closed state, in which ions cannot drift through the ion gate in the intended drifting direction, and an open state, in which ions can drift through the ion gate in the intended drifting direction. This is accomplished by applying potentials that alternate over time to one or more of the electrodes. In a switching cycle of the ion gate, which comprises the open state and the closed state of the ion gate, two different closed states of the ion gate are produced. In a first closed state, the ion gate is closed by applying a first potential between the second and third electrodes.

  • Patent number: 10426907
    Abstract: A method and a system control a drug dosing device (1) for administering a drug to a patient (19). The quantity (c0) of the drug administered from the drug dosing device (1) is determined or calculated. The concentration of the drug in the gas exhaled by the patient (19) is measured as a first patient value (c1M). A simulation calculation is carried out, in which a second patient value (cp) is calculated from the administered quantity of the drug (I), taking into account a parameter (k10). A simulated first patient value (c1?) is calculated in the simulation calculation, taking into account the parameter (k10). A comparison of the simulated first patient value (c1?) to the measured first patient value (c1M) is carried out. The parameter (k10) is adapted on the basis of the comparison. The calculated second patient value (cp) is used to generate a control signal (S).
