Abstract: A device detects the removal of drugs from a drug blister pack. The device contains a base for receiving the drug blister pack which has a base surface which is configured for contact with the electrically conducting, metal foil that closes the pockets. In the region of the pockets, the base has holes that are configured for the passage of the drugs present in the pocket. In the region of the holes one transmitting coil and at least two receiving coils are each arranged and extend around the respective hole. The receiving coils are associated with each other with respect to the transmitting coil and are arranged such that when the foil resting against the base in the region of the respective hole is undamaged the difference of the voltages induced in the receiving coils by an electric current in the transmitting coil lies below a predetermined threshold value.

Abstract: A device detects the removal of drugs from a drug blister pack. The device has a base for receiving the drug blister pack and a base surface which is configured for contact with the electrically conducting foil that doses the pockets of the blister pack. In the region of the pockets, the base has holes that are configured for the passage of the drugs present in the pockets, every hole being arranged in the region of one of the pockets. A coil is arranged in the region of each of the holes and extends around the respective hole, in particular exclusively the respective hole. A detector unit is provided which produces an electrical field and/or magnetic field in the region of one or more holes by one of the coils and analyzes the voltage or the current on at least one of the coils extending around the hole.

Abstract: A shield element for mounting on an object, in particular a flat object, such as a chip card. The object has a base body, an RFID or NFC transponder, a transponder chip and a coil-shaped transmission antenna connected to the RFID or NFC transponder chip. The shield element has a carrier made of non-conductive material. The carrier has a closed or closable conducting path which, upon mounting the shield element on the object, shields the object from the electromagnetic fields generated by an external reading device and directed at the transmission antenna of the RFID or NFC transponder chip.

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. The antenna is free of interruptions, at least partially along the loop which is electrically interrupted by the interruption.

Abstract: A housing wall for a data communications device includes a metallic and electrically conductive main body. A slotted area having a number of slots is provided in a region of the housing wall, in such a way that in a region of the slotted area the housing wall is permeable to magnetic fields for inductively coupling-in signals for wireless communication.

Abstract: A dispensing device for dispensing liquids, particularly liquid medications to people, contains a container which is filled with a liquid and which has an opening at one end for dispensing same. The dispensing device further has at least one pair of capacitive measuring electrodes which are arranged in an outer region of the container, particularly on the wall, opposite one another, for determining the permittivity of the respective medium in the intermediate region between the measuring electrodes. A shield is arranged around the container and surrounds the measurement electrodes in a sheath-like manner.

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.
