Abstract: A method for determining a switching state of a valve that is actuated by a coil, wherein the method includes: respectively ascertaining a current flowing through the coil and a voltage applied to the coil at several times which follow one another with a prespecified time interval, calculating an inductance variable of the coil based on the currents, the voltage and the time interval, and determining the switching state based on the inductance variable. Also disclosed is a solenoid valve assembly.

Abstract: An elongated incubation trough has an indentation open toward a top end as well as a bottom. The indentation has a first receiving area to receive an elongated test strip as well as a second receiving area to receive an end section of a fluid line. The second receiving area is in fluidic communication with the first receiving area. A maximum width of the second receiving area at bottom height is greater than a maximum width of the first receiving area at bottom height.

Abstract: The invention relates to a cap (1) for a display and/or control element. Said cap (1) comprises a cap member (3) for covering a light source (7) and optionally also actuating a switch of an associated control element. A luminous area or projection area is embodied in the cap member (3) in such a way that a symbol represented on or through the luminous area or projection area becomes visible on an operator's side of the display and/or control element by irradiating the symbol by means of a light source (7). The luminous area or projection area encompasses a light-permeable metal coating (2) which is preferably applied using a PVD process. The cap is characterized in that the metal coating (2) has a three-dimensional contour (2a, 2b) for representing the symbol. The invention further relates to an associated production method, a display or control element comprising said cap, and a use.

Abstract: In accordance with 37 C.F.R. §§1.72(b) and 1.121(b), please amend the abstract as follows: Operating element with a capacitive sensor, for activating a function display and/or backlighting system, for example in the case of approach, comprising the following: a button or pressure switch for a switching functionality, a layered film structure defining the operating surface, which is in operational engagement with the button or pressure switch in such a way that the button or pressure switch is actuated by pressing on the operating surface, characterized in that the layered film structure comprises at least one film, for example a polycarbonate film, and a conductive layer applied onto the film, preferably on the side of the film facing away from the operator, for providing at least one electrode of the capacitive sensor.
