Abstract: An electric motor with a housing, at least two terminal contacts and at least one suppression device against electromagnetic emissions, wherein the suppression device comprises at least one circuit carrier with at least one filter circuit, wherein the circuit carrier is arranged on an end side of the electric motor, and wherein the filter circuit is electrically connected to the two terminal contacts. The manufacturing effort is reduced in that at least one contact means electrically connected to the filter circuit is attached to the circuit carrier, and in that the contact means bears against a ground contact with at least partial deformation, so that the filter circuit is electrically connected to the ground contact via the contact means.

Abstract: The invention relates to a building or enclosure termination opening and/or closing apparatus (10) having communication signed or encrypted by means of a key, and to a method for operating such. To allow simple, convenient and secure use by exclusively authorised users, the apparatus comprises: a first and a second user terminal (14, 30), with secure forwarding of a time-limited key from the first to the second user terminal being possible. According to an alternative, individual keys are generated by a user identification (42) and a secret device key (40).

Abstract: The present invention relates to a module for cooling heat generating components, in particular for cooling electronic components of a computer device, such as processors, memory modules, storage modules, that may be arranged on a motherboard. The method according to the invention, comprises at least one heat generating component, a gastight chamber having an interior volume having arranged therein a heat-transfer fluid in liquid phase that is in heat transfer contact with at least part of the heat generating component and a heat exchanging surface for transferring heat from the heat-transfer fluid out of the gastight chamber, wherein the gastight chamber comprises a displaceable wall by means of which the interior volume of the gastight chamber is variable, and wherein the interior volume of the gastight chamber is in pressure equilibrating connection with the ambient pressure outside the gastight chamber via the displaceable wall of the gastight chamber.
