  • Patent number: 11927597
    Abstract: A laboratory sample vessel distribution system is presented. The system comprises a cabinet, sample vessel carriers for receiving sample vessels, and a cabinet drawer for receiving a sample vessel carrier. The drawer is locatable in different positions: closed, opened, and fully opened. An actuator moves the sample vessels and the sample vessel carriers between different locations. An actuator driver drives the actuator and applies a first mode of operation with a first speed and a second mode of operation with a second reduced speed compared to the first speed. A sensor device detects between opened and closed positions and provides position signals. A control device is connected to the actuator driver and the sensor device. The control device provides control signals to the actuator driver instructing the actuator driver to apply either the first mode, if in the closed position, or the second mode, if in the opened position.

  • Patent number: 11396697
    Abstract: A device for depositing a layer on a substrate, while a mask is placed on the substrate, includes an adjustment device for adjusting the position of a mask carrier with respect to a support frame. The adjustment device has, on the support frame, an adjustment lever that is mounted to rotate about an axis of rotation of a pivot bearing and that has a first and second arm. The second arm acts on the mask carrier, and a control rod that can be vertically displaced by an actuator acts on the first arm. For a vertical adjustment device, the second arm and the first arm extend in a horizontal direction, in which the second arm acts on a push rod that is connected to the mask carrier. For a horizontal adjustment device, the second arm extends in a vertical direction and the first arm extends in a horizontal direction.

  • Publication number: 20220065880
    Abstract: A sample container transport system for moving sample containers in an in-vitro diagnostic (“IVD”) laboratory system is proposed, the sample container transport system comprising a gripping apparatus for gripping sample containers, and a robotic movement apparatus for moving the gripping apparatus in multiple directions, characterized in that the sample container transport system comprises a multidimensional-force sensor that is designed for detecting a multidimensional-force signal indicative of forces in multiple directions acting on a sample container gripped by the gripping apparatus. Further, a method for using the sample container transport system is proposed.
