  • Patent number: 10165998
    Abstract: A method and a system for determining an angle between two parts of a bone that are twisted relative to one another about the axis of a bone shaft. The system is particularly suitable for determining the antetorsion angle of a femur. In order to determine an antetorsion angle of a bone easily intraoperatively, a method with the following steps is proposed: establishing the position of a first orientation feature assigned to a first part of the bone, in particular a femoral neck axis, using an imaging method, establishing the position of a second orientation feature assigned to a second part of the bone, in particular a condyle tangent or a condyle plane, using an imaging method, and determining the angle, in particular the femoral antetorsion angle, from the positions of the two orientation features.

  • Patent number: 10132765
    Abstract: A multi-layer arrangement of III-V semiconductor layers includes a strained III-V semiconductor layer having a concentration of a constituent element which effects intensity of a conductive channel formed in the multi-layer arrangement. Lattice parameters of the strained III-V semiconductor layer are determined by generating a first scan in a Qx direction for a chosen reflection in reciprocal space based on diffracted X-Ray beam intensity measurements in the Qx direction. A second scan is generated in a Qz direction for the chosen reflection in the reciprocal space based on diffracted X-Ray beam intensity measurements in the Qz direction. The second scan is aligned with a diffracted X-Ray peak in the first scan which identifies the strained III-V semiconductor layer. The degree of strain of the strained III-V semiconductor layer is determined based on the first scan and the concentration of the constituent element based on the second scan.
