Abstract: Disclosed is a battery cell including an electrode, a housing, a cell interior inside the housing, a temperature sensor, and a heat-conducting part which differs from the electrode, is entirely or partially disposed inside the housing of the battery cell, and is thermally connected to the temperature sensor.

Abstract: The invention relates to an arrangement for producing a Bessel beam (5), comprising a beam-forming element (2), which transforms a beam (1) incident as a plane electromagnetic wave into a Bessel beam (5). According to the invention, the beam-forming element (2) comprises at least one annular lens (3, 3?) and a Fourier optical unit, e.g. in the form of a Fourier lens (4).

Abstract: An adjustment system and method is provided for determining a set position of a motor-driven adjustment part of a motor vehicle by a Hall sensor, which is arranged in a rotated magnetic field. The drive of the adjustment part is activated for a specified number of approaches of the adjustment part toward an end position. A counter is changed by a counting value upon each approach of the adjustment part toward the end position. A standardization drive to the end position is carried out when the specified number of approaches is reached, and each deactivation and/or activation of the Hall sensor is detected and the counter state of the counter is changed according to the number of deactivation and activation cycles.

Abstract: An electric window lifter of a vehicle with a vehicle door having a frameless window is actuated according to a novel, low-wear actuation method. An entry signal is acquired that allows a conclusion to be drawn about whether a person has entered through this vehicle door. In this case, the window pane that is associated with the window of this given vehicle door is lowered by a short stroke by way of the window lifter in response to a central exit signal only when the entry signal was first identified. The window lifter or power window assembly includes an associated actuation unit with a query module that is configured for automatically carrying out the method.

Abstract: The invention relates to a current transformer (1) for measurement and protection purposes in high- or medium-voltage power supply networks which include busbars guided in support insulators, which current transformer is characterized in that a busbar (3) is surrounded, in the range of the head (21) of a support insulator (2), in a spaced-apart relation by a non-closed ring (4) of magnetically conductive material which is arranged within the material of the support insulator (2); that the magnetic field sensor (5) is arranged, also within the material of the support insulator (2), in the gap between the open ends of the ring (4); and that the connecting leads (6) of the magnetic field sensor (5) are guided through the body (22) of the support insulator (2) as far as the base (23) thereof and are capable of being tapped there.
