Abstract: An electromagnetic valve for a hydraulic system for an automatic transmission of a vehicle. An armature chamber is filled with hydraulic medium and fluidically connected to hydraulic lines of the hydraulic system. An armature is mounted in the armature chamber such that its stroke is adjustable. The armature includes a shut-off body and divides the armature chamber into an opening-side chamber facing the flow opening and into an inner chamber facing away from the flow opening. During a stroke of the armature, an oil exchange occurs, and a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. A hydraulic line leading to the opening-side chamber or to the inner chamber of the armature chamber includes a dirt collecting element that is designed as a permanent magnet and that retains contaminations in the hydraulic medium that flows through the hydraulic line during an oil exchange.

Abstract: An electromagnet for a hydraulic system, such as an automatic transmission of a motor vehicle. The electromagnet may include an armature chamber filled with hydraulic medium, which may be fluidically connected to hydraulic lines of the hydraulic system, and may have an armature mounted therein. The armature may have an adjustable stroke and may include a shut-off body. The armature may divide the armature chamber into an opening-side chamber facing the flow opening, and an inner chamber facing away from it. During a stroke movement of the armature, an oil exchange may occur, during which a displacement volume of the hydraulic medium overflows from the opening-side chamber into the inner chamber. The electromagnet may further include a hydraulic medium reservoir, which may store a hydraulic medium having a higher degree of purity than the hydraulic medium in the hydraulic lines and which may be fluidically connected to the opening-side chamber.

Abstract: A technique is disclosed for the creation and the use of a telecommunications link between two users of a telecommunications network. Disclosed in particular is the technical creation of a social links network employing a telecommunications network. A method is disclosed for creating a telecommunications link between a first set of communications devices associated with a first user and a second set of communications devices associated with a second user, including generating a pair of certified identifiers of the first and second users allowing a communications session to be set up between at least a communications device of the first set and a communications device of the second set.

Abstract: The invention relates to an operating panel arrangement, in particular for domestic appliances such as washing machines and tumble dryers. An operating panel has formed on its outside actuating sections and display sections for operating or monitoring purposes. An electrical circuit arrangement is coupled to the actuating sections and the display sections and is arranged in the region of the inside of the operating panel. In this case, the circuit arrangement has at least three electrodes, which are arranged in a manner distributed approximately parallel to the operating panel. The circuit arrangement has evaluation means which are designed to calculate the spatial position of an operating means in relation to the position of the three electrodes, to be precise by evaluating the fields between the electrodes and the operator. The actuating sections can be freely defined as positions of the operating means in the region of the outside of the operating panel.
