  • Patent number: 10429178
    Abstract: An arrangement measures coordinates of a workpiece and/or machines the workpiece. The arrangement has a first part and a second part that can be moved relative to the first part. The relative mobility of the first and second parts is specified in addition to a possible mobility of a probe that is optionally additionally fixed to the arrangement. The mobility of the probe is specified by a deflection of the probe from a neutral position during a mechanical probing of the workpiece for the purpose of measuring the coordinates. A measuring body is arranged on the first or second part, and at least one sensor is arranged on the other part, i.e. on the second or first part. The sensor generates a measurement signal corresponding to a position of the measuring body and thus corresponding to the relative position of the first and second part.

  • Patent number: 10393908
    Abstract: A bobbin for holding inductive coils includes features that yield a smaller overall size and prevent irregular and asymmetric coil windings. The bobbin comprises a central hub and a single flange that extends from a middle circumference of the hub. The bobbin includes no end flanges at the ends of the central hub, reducing the height of the bobbin. The interface between the flange and the hub is a sharp corner with little or no radius, facilitating regular and symmetrical coil geometries. Coil assemblies can be attached to the respective two sides of the flange concentrically with the hub. Each coil assembly can be formed by winding a transmitter coil, then winding a receiver coil concentrically over the transmitter coil. Conductive pins that extend from the outer edge of the flange interface the coil lead wires to a printed circuit board of an inductive sensor or other device.
