摘要:
A method is provided for reducing an impact speed of an armature on a pole face of an electromagnet in an electro-magnetic actuator, in which the armature moves toward the pole face against a restoring spring force when the coil of the electromagnet is charged with current. The method includes limiting a voltage applied to the coil to a predeterminable maximum value as the armature approaches the pole face so that a current flowing through the coil drops for a portion of the time of the voltage limitation.

Predicting a drill string stuck pipe event. At least some of the illustrative embodiments are methods including: receiving a plurality of drilling parameters from a drilling operation; applying the plurality of drilling parameters to an ensemble prediction model comprising at least three machine-learning algorithms operated in parallel, each machine-learning algorithm predicting a probability of occurrence of a future stuck pipe event based on at least one of the plurality of drilling parameters, the ensemble prediction model creates a combined probability based on the probability of occurrence of the future stuck pipe event of each machine-learning algorithm; and providing an indication of a likelihood of a future stuck pipe event to a drilling operator, the indication based on the combined probability.

A piezoelectric component includes an electromechanical transducer with two first electrodes and a second electrode. The second electrode is arranged between the two first electrodes. The transducer also includes a first main side, a second main side, opposite from the first main side, and a first longitudinal side. A first contiguous metallization layer is arranged on a first partial region of the first main side and on a partial region of the first longitudinal side adjacent to the first partial region of the first main side. Here, the partial region of the first longitudinal side is kept at a sufficient distance from a side edge facing the second main side and the partial region electrically contacts the at least two first electrodes.

摘要:
A connection arrangement having an outer conductive structure arranged at least partly or completely in a cutout of an electrical insulation layer is provided. An inner conductive structure is arranged at the bottom of the cutout on one side of the insulation layer. The inner conductive structure adjoins the outer conductive structure in a contact zone. A contact area is arranged at the outer conductive structure on the other side of the cutout. The contact zone and the contact area do not overlap. The bottom of the cutout is arranged to overlaps at least half of the contact area, to provide a step in the insulation layer at the edge of the cutout outside a main current path between the contact area and the inner conductive structure.

摘要:
An integrated circuit and fabrication method are presented. The integrated circuit includes a capacitor containing a base electrode, a covering electrode, and a dielectric between the base and covering electrodes. The dielectric contains an oxide of a material contained in the base electrode, which may be produced by anodic oxidation. A peripheral edge of the dielectric is uncovered by the covering electrode. A base layer on the capacitor includes a cutout adjacent to the dielectric. During fabrication, the base layer protects the material of the base electrode that is to be anodically oxidized from chemicals, and also protects the surrounding regions from anodic oxidation. A precision resistor may be fabricated simultaneously with the capacitor.
