Abstract: A medication injector for dispensing liquid medications to people includes a container which is filled with the liquid and which has an opening at one end for dispensing the liquid and at least one pair of capacitive measuring electrodes disposed opposite each other in the outer region of the container, in particular on the wall, for determining the permittivity of the respective medium in the intermediate region between the measuring electrodes. The measuring electrodes are used by the injector to determine the fill level of the container. A shielding surrounds the measuring electrodes in the manner of a sheath, is disposed around the container, and reduces possible external interfering influences on the capacitive measurement, such as those resulting from contact, for example. Additionally, a contact sensor is provided which can indicate the measurement as invalid.

Abstract: A dispensing device and a method for dispensing liquids, in particular liquid medicaments, to persons, has a liquid-filled container an opening for dispensing the liquid at one end. A holder for holding an injection needle for injection of the liquid from the container are provided in the area of the opening. A measurement system determines a measured value, and a processing unit determines a parameter value, associated with the container, based on the measured value. At least one detection element is present at the opening and connected to a needle detection circuit. The needle detection circuit measures an electrical characteristic variable that can be picked up at the output of the detection element. The measurement result is fed to a processing unit, which calculates the parameter value and keeps it available at its output.

Abstract: A can includes an at least partially electrically conductive body having a seal region delimited by a predetermined breaking edge on a front wall. An opening element bears against the front wall and is connected to the front wall at least at one point in an initial position. When the opening element is pivoted into an opening position, the seal region tears away at the predetermined breaking edge and forms an opening for emptying the contents of the can. The opening element has a metallic basic body which has a loop with an electrical interruption at one end region. An antenna and a transponder chip which is connected to the antenna are provided. The antenna bears at least partially against and is electrically insulated from the basic body.

Abstract: A can includes a body, a sealing area on a wall delimited by a breaking edge, an opening element which in an initial position abuts the wall and is connected to the wall by a connecting element of the opening element. Pivoting the opening element into an open position tears the sealing area along the breaking edge and forms an emptying opening in a region delimited by the breaking edge. The opening element has a carrier body of electrically and/or magnetically insulating material, the opening element carries an antenna on or in the carrier body and a transponder chip connected to the antenna. An electric connection line electrically conductively interconnects and short-circuits terminals of the antenna in the initial position. The electric connection line is irreversibly interrupted and activates the antenna when opening the can by pivoting the opening element from the initial to the open position.

Abstract: A device for detecting the position of an actuator has a conductor arrangement, which detects magnetic fluxes flowing therethrough and converts same into a voltage signal that is dependent on the position, at which the magnetic flux penetrates the conductor arrangement. The induced voltage signal is proportional to the position of the magnetic flux, measured along a predetermined axis starting from a predetermined starting point. A position-determining unit is connected to the conductor arrangement for determining the position of a magnetic flux generated by the actuator and passing though the conductor arrangement. A transmission unit, by way of which the determined position is transmitted to a receiver, is arranged downstream of the position-determining unit.
