    摘要： In the operation of piezoactuators of multilayer construction, during the polarizing or during the operation of the piezoactuator tears can arise, due to voltages, in the metallization strips that are attached to the actuator on the outside for contacting the electrode layers. It is inventively proposed to install electrically conductive contact lugs directly at the stack or on the metallization strips such that a laterally protruding region remains, so that, even given arising tears, these nevertheless extend in the protruding region of the contact lug, and the tears are electrically bridged. Electrical terminal elements are provided so as the project above or laterally at the contact lugs.

    摘要： A piezoelectric stack (1) has alternately successive piezoelectric layers (2) and inner electrode layers (3, 4) which are alternately electrically connected to two outer electrodes (7, 8) which are arranged on the outer side (5, 6) of the piezoelectric stack (1). The piezoelectric stack (1) also has at least one safety layer (9, 40, 50) which is arranged between two successive piezoelectric layers (2) instead of one of the inner electrode layers (3, 4). The safety layer (9, 40, 50) is structured in such a manner that it has an internal interruption (13, 44, 45, 53) which is configured in such a manner that the safety layer (9, 40, 50) does not form an electrical contact between the two outer electrodes (7, 8) if it contact-connects both outer electrodes (7, 8) and is electrically conductive.

    摘要： The invention relates to the prevention of injuries and material damage caused by doors (2) of stopped and/or parked motor vehicles (1) by means of at least one camera (4) which monitors the exterior (3) of, especially the space next to and/or above, the vehicle (1). According to the invention, a mode of operation monitoring the inner (7) and/or outer (8) door handle is activated and the exterior (3) of the motor vehicle (1) is monitored by means of the camera (4) if an evaluation unit (6) detects that a fixed or variable speed-related, acceleration-related, and/or distance-related threshold value (SW) is not met, e.g. when the vehicle (1) is stopped, or if said evaluation unit (6) detects that a signal unlocking the locking mechanism of the vehicle doors (2) is received while causing an acoustic, optical, and/or haptic warning signal to be issued as soon as a person actuates or unlocks optionally in an automated manner the vehicle door (2) handle (7, 8) even though a stationary (9) or approaching (10) object has been detected in the field of vision (5) of the camera (4).

    摘要： A device and method that can form a plurality of chamfered orifices where the orifices are consistent dimensionally, such as, for example, the diameter, the surface roughness, and/or the geometry of the chamfers. The device includes a laser light source that emits generally coherent light along an axis towards a workpiece. The device also includes a splitter assembly that directs a first portion and a second portion of the generally coherent light about the axis such that at least one orifice and at least one chamfer is formed in the work piece. The device is configured such that it can form an orifice and at least one chamfer having a surface roughness of less than two microns and an orifice coefficient ratio at least 0.6. The preferred method includes providing at least a first beam and a second beam that are emitted from the laser light source, and forming at least one orifice in the work piece by directing at least one of the first and second beams towards the workpiece. The method further includes targeting the other of the at least one of the first and second beams to form the at least one chamfer in the at least one orifice to provide for an orifice coefficient of at least 0.6.

    摘要： A method for adjusting the calibration of a circuit breaker trip mechanism including a terminal element, a bimetal element connected thereto, and a trip bar. Laser energy is applied to lanced or pre-bent surfaces of the terminal element to thermally induce displacement thereof and thereby modify a trip distance between the bimetal element and the trip bar. Where a laser beam is directed to fall on a middle leg of a lanced or pre-bent section of the terminal element, the bimetal element moves in one direction relative to the trip bar. Conversely, where a laser beam is directed to fall on lateral legs of the lanced or pre-bent section of the terminal element, the bimetal element moves in an opposite direction relative to the trip bar. Thus, laser energy may be applied from the same direction, or to the same side of the trip structure, regardless of whether the trip time is to be increased or decreased.
