    Abstract: Disclosed herein is a tool holder (2) for a machine comprising
    - a frame (8) comprising at least one hook-shaped cut-out (22) for receiving a first bracket pin (6) of a tool (1) and a least one partial cut-out (24) for receiving a second bracket pin (6) of the tool (1);
    - an actuator (18) connected with one end to the frame (8), said actuator (18) comprising an actuator housing (30) arranged movable compared to the frame (8) upon activation of said actuator (18), the actuator housing (30) further comprising lock fingers (20) that are designed to change the shape of the at least one partial cut-out (24) so that second bracket pin (6) of the tool (1) can be locked in the tool holder and the at least one partial cut out (24), respectively;
    - an actuator positioning system (10) comprising a pattern (14), a sweep sensor (16), a processor (32) and a computer readable memory (34), wherein
    the sweep sensor (16) is arranged on the frame (8) and the pattern (14) is arranged on the actuator housing (30), whereby the pattern (14) is designed so that the sweep sensor (16) can detect the pattern (14) and generate a corresponding signal, which can be analysed using the processor (32) and the computer readable memory (34) for providing information relating to the actuator (18).

    Abstract: There is provided an absolute encoder advantageous in accuracy of an output thereof against a defect in a scale thereof. In the absolute encoder, a detector detects a part of an array of marks of the scale, and outputs a data sequence corresponding to the part. A processor stores information indicating a correspondence between each of a plurality of code sequences and an absolute coordinate of motion of the scale, and outputs information of the absolute coordinate based on the data sequence and the information. The processor detects an error of the data sequence, and performs rewriting of the information based on the detected error.

    Abstract: Die Erfindung betrifft eine absolute Positionsmesseinrichtung, die derart eingerichtet ist, dass Fehler der Positionsmessung sicher und mit möglichst wenig Aufwand aufgedeckt werden. Hierzu werden Codeelemente (C1 bis C5) eines seriellen Codes (C) jeweils von mehreren Abtastelementen (D1 bis D6) abgetastet und über diversitäre Auswahlmethoden die Abtastelemente (D1 bis D6) ausgewählt, die eine sichere Abtastung gewährleisten. Die damit gewonnenen Positionsmesswerte (POS1, POS2) werden zur Fehlerprüfung miteinander verglichen.

    Abstract: The invention relates to a magnetic position sensor comprising at least one permanent magnet. The invention also relates to a magnetic device for detecting a torque between a first shaft and a second shaft that are connected via a torsion bar. The aim of the invention is to provide a device for determining the multi-periodic absolute position of a magnetized unit. The subject of the invention is therefore a magnetic position sensor (A) comprising at least the following: a magnetized unit (1), a first magnetosensitive probe (2) and a second magnetosensitive probe (3). The second magnetosensitive probe (3) is capable of measuring a number of complete rotations of the magnetic field in an absolute, incremental and reversible manner so as to determine a second datum relating to the position of the magnet (1), whether or not this second magnetosensitive probe (3) is powered. The sensor further includes a module for calculating the absolute position of the magnet (1) on the basis of the first and second data coming from the first and second probes (2, 3) respectively.
