Abstract: The invention relates to a patella gripper for a patella, comprising a retaining element (3; 53) and a contact finger apparatus (4; 54), wherein the contact finger apparatus (4; 54) is arranged on the lower face of the retaining element (3; 53), wherein the contact finger apparatus (4; 54) comprises at least two contact finger units (4.1, 4.2; 54.1), which are arranged on opposite sides of the retaining element (3; 53), and wherein the contact finger apparatus (4; 54) is designed in such a way that the patella can be moved in the cranial-caudal direction and in the medial-lateral direction by means of the contact finger units (4.1, 4.2; 54.1). The invention further relates to a device (20; 60) having such a patella gripper (1; 51).

Abstract: A scale and related method for a length-measuring system for recording the absolute values of angles or distances. The scale includes a printed circuit board, at least one track for identifying length information or angle information and a coding for identifying the scale. The coding has at least one coding element comprising at least two electrodes and a conductive connection between the electrodes on an insulator substrate. The electrical connection is configured to be irreversibly destroyed when an electrical current is applied.

Abstract: A fully automatic extraction and analysis system for biologically active samples significantly simplifies the analysis of, for example, DMS samples and has significant advantages over the manual technology and the partially automated technology (punching out). The described extraction system is the first economical alternative to conventional blood analysis and supports the spread of said time-, cost-, and animal-saving technology in pharmacology and toxicology.
