Abstract: An apparatus 100 for releasing a die 150 with a vacuum platform 130 with two or more segments 140 is provided, which may be extended independently of the surface of the vacuum platform 130 to push against the adhesive film 110 at the respective attachment in the direction of the die gripper 170. By providing two or more segments 140 that are independently extendable, die detachment (or at least partial detachment) may be performed in parallel, and two or more dies 150 may be detached before the adhesive film 110 needs to be repositioned. Both measures may increase throughput. In addition, empty attachment positions may be omitted.

Abstract: A rotor for an electrical machine has a rotor core with a center line, which forms an axis of rotation. The rotor core can be subdivided by a plurality of imaginary radial planes, which extend radially from the axis of rotation at regular angular intervals. For each radial plane, at least one pair of winding grooves is formed, which extend through the rotor core to either side of the radial plane with the radial plane serving as the plane of symmetry. A winding is arranged in each pair of winding grooves, in winding receiving areas of the winding grooves, which winding extends through the two winding grooves of the pair. Each winding groove is bounded in its winding receiving area on its side facing the assigned radial plane by a side face, which continues in a manner free from projections, in the sense of projections in a direction away from the radial plane, from the winding receiving area to the radially outer end of the winding groove.

The system includes at least one camera for taking at least one image of at least one first subregion of the container, at least one thermal-imaging camera for taking at least one thermal image of at least the first subregion, and an evaluation unit. The evaluation unit determines the process variable based upon the at least one thermal image in combination with the at least one image, wherein the latter is used in the determination of the container geometry. The system according to the present disclosure thus offers the advantage that none of the components must be arranged in the interior of the container.

Abstract: A method for monitoring the functioning of a field device, wherein the field device provides a complex measurement signal, which is produced from a number of individual measurements following one another in time, comprising method steps as follows: the complex measurement signals are stored within a predetermined time window; the occurrence of a predetermined event is monitored in the field device; the stored complex measurement signals are overwritten for the case, in which the predetermined event does not occur within the predetermined time window; for the case, in which the predetermined event occurs within the predetermined time window, both a first defined number of complex measurement signals, which were ascertained in time directly before the occurrence of the event, are frozen, as well as a second defined number of complex measurement signals, which were ascertained in time directly after the occurrence of the predetermined event, are stored.

Distinguishing features include: that at least one modulation element introduced into, or placed in, the pipeline produces, at least for the case, in which the medium is flowing with a velocity different from zero, a change in density of the medium, at least at times, in the vicinity of the modulation element; that at least one mechanically oscillatable unit introduced into, or placed in, the pipeline and spaced from the modulation element is excited to resonant oscillations; that mechanical oscillations are received by the mechanically oscillatable unit and converted into an electrical, received signal, wherein the received signal is sensitive to the density change; and that the at least one flow characteristic of the medium is determined from the reaction of the received signal of the mechanically oscillatable unit to the density change.

Abstract: A bonding head for mounting semiconductor chips on a substrate comprises a bonding head body and a suction member formed of a single piece. The elements necessary for heating, cooling and monitoring the temperature of the suction member are all integrated into the suction member, so that neither the heating nor the cooling elements are separated from the semiconductor chip by a surface preventing the heat transfer. The bonding head body contains only the elements necessary for supplying the suction member with electrical power and with the cooling medium.

Abstract: A method for mounting components on a substrate includes receiving a component with a suction member which is mounted on a bonding head, displacing the bonding head relative to the substrate by means of a first movement axis and a second movement axis in order to position the component in a target position above the substrate, lowering the suction member by means of a third movement axis until the component touches the substrate, producing a predetermined bonding force with which the suction member presses the component against the substrate, and displacing at least one of the bonding head and the substrate by means of at least one of the first movement axis by a corrective value W1 and the second movement axis by a corrective value W2 in order to correct an inclined position of the suction member produced during the build-up of the bonding force.
