  • Patent number: 11327044
    Abstract: An electrochemical sensor (1, 101) has a sensor element (15, 115) with a measuring surface (8, 108) that faces a measuring medium (5) during use. The sensor element has a planar measuring element (2, 102). A sensor shaft (4, 104) has an aperture (13, 113) with a bezel (11, 111) at an end which, during use, faces the measuring medium. The sensor element is installed in the area of the aperture. The electrochemical sensor also has an annular sealing element (9, 109), which is arranged between the sensor element and the bezel. An insulator element (10, 110) is firmly and inseparably connected to the measuring element, exposing or recessing the measuring surface. Thus, the sealing element, which protects the electrochemical sensor against the ingress of measuring medium, is arranged sealingly between the insulator element and the bezel.

    Abstract: A calibration weight assembly (100, 200, 300, 400, 500) has at least one calibration weight (150, 550, 750) and a transfer mechanism, and is used with a gravimetric force-measuring device (110, 210, 310, 410, 510) having a fixed region (111, 211, 311, 411, 511), a load-receiving region (112, 212, 312, 412, 512), and a measuring sensor (140, 540). The transfer mechanism has at least one poly-stable positioning element (561, 571), a first stable state of which defines a calibration position (KP) and a second stable state of which defines a resting position (RP) of the transfer mechanism. The at least one calibration weight can be coupled with the load-receiving region. The transfer mechanism, as actuated by the measuring sensor, transfers the at least one calibration weight from the calibration position to the resting position, or vice versa.

  • Patent number: 11035662
    Abstract: Cargo objects, in a freight-related environment, are dynamically dimensioned while being held at a cargo-handling position of a vehicle. A three-dimensional model is obtained comprising points representing surfaces of the vehicle. Using the model, the position of a point of reference of a first wheel of the vehicle is obtained, as is the position of a split point relative to the position of the first wheel point of reference. A driving direction of the vehicle is obtained. A splitting plane is determined, which passes through the split point and is perpendicular to the driving direction. A three-dimensional model of the cargo is determined by subtracting, from the vehicle three-dimensional model, the points that are positioned on the side of the splitting plane opposite to the side of the splitting plane that make up the first wheel point of reference. The volume is then determined from the cargo three-dimensional model.
