An apparatus () for interrupting a light beam, in particular a laser light beam, with a light beam deflection device (), wherein the light beam deflection device () is arrangeable in the light path of the light beam. An apparatus () is characterized in that the light beam deflection device () is arranged on a bendable material strip (), wherein the material strip () is held on one side on one end and magnetizable or magnetic sections () are arranged on the area facing away from the held end of the material strip (), preferably on both sides of the material strip (), wherein a magnet () is provided for each section arranged on the material strip () and wherein the sections () are or can be brought in engagement with the magnetic field of each magnet ().

The present invention relates to a lancet device, by which a lancet can be displaced along a piercing path for generating a piercing wound in a skin surface, in particular to obtain bodily fluid for diagnostic purposes, comprising a lancet drive having drive means to generate a drive force for a piercing movement of the lancet along the piercing path in the direction toward the skin surface. According to the present invention, the lancet drive comprises a magnet, by which a magnetic retention force oriented opposite to the drive force may be generated, and the lancet drive also comprises triggering means, by which the retention force may be reduced enough that the lancet is accelerated in the direction toward the skin surface under the effect of the drive force generated by the drive means. The present invention also relates to a method for generating a piercing wound, in which the drive spring is held in a tensioned state using a magnetic retention force oriented opposite to the drive force before the triggering of a piercing wound.

An actuation magnet is provided for moving a closure needle of a hot-runner nozzle of an injection molding tool. The actuation magnet has an armature which is coupled in movement to the closure needle and may be displaced between first and second cores by subjecting at least one coil to current. A permanent magnet is arranged in a manner such that it exerts an additional magnetic force on the armature in at least one, preferably two, movement directions.
