Abstract: The invention relates to a dosing system (1) for dosing a dosing material. The dosing system (1) has a housing (11), comprising a nozzle (70) and a supply channel (62) for dosing material, and a discharge element (80) movably mounted in the housing (11) and an actuator unit (10) coupled to the discharge element. The actuator unit (10) comprises an actuator (12) having a membrane (13) which can be pressurized by means of a pressure medium in order to move the discharge element (80) in a discharge direction (RA). The discharge element (80) is formed separately and, for coupling to the actuator unit (10), is pressed by means of a force acting on the discharge element (80) against a side surface (19) of the membrane (13) pointing in the direction of the discharge element (80). Furthermore, the invention relates to a method for controlling a dosing system (1).

Abstract: The invention relates to a dosing installation (1) comprising at least one dosing device (2), which dosing device (2) has at least one dosing system (3) comprising at least one dosing head (5) for dispensing a dosing material; and at least one change system (6, 6?) assigned to the dosing device (2). The dosing device (2) and/or the change system (6, 6?) and/or the dosing system (3) are designed and can be controlled by a control device (7) in such a way that, in order to form a dosing head (5), at least one first dosing head component (A) can be detachably coupled to at least one second dosing head component (B) in an automated process via the change system (6, 6?). The invention also relates to a change system (6, 6?) and a dosing device (2) for such a dosing installation (1) as well as to a dosing system (3) and a dosing head (5) for a dosing system (3).

Abstract: The invention concerns a dosing unit (1) with at least one dosing device (2), the dosing device (2) having at least one dosing system (3) with at least one dosing valve (4) for the delivery of a dosing material, and with at least one exchange system (5) associated with the dosing device (2). The dosing unit (1) is configured and can be controlled by a control device (6) in a manner such that, in an automated process, at least the dosing valve (4) can be detachably coupled with the dosing device (2) for the purposes of delivering dosing material via the exchange system (5) and/or in a manner such that, in an automated process, at least the dosing valve (4) can be detachably coupled with a supply device (7) via the exchange system (5). The invention furthermore concerns an exchange system (5) for a dosing unit (1), a dosing device (2) for a dosing unit (1) and a dosing system (3) with a dosing valve (4) as well as a dosing valve (4) for a dosing system (3).

Abstract: The invention relates to a system and method, by means of which the availability of readable contents (books, magazines, documents) can be linked according to location. The invention further relates to an electronic terminal, in particular a mobile reading device, having means for carrying out said method, and to the use of such an electronic terminal.

Abstract: Presented is a comprehensive infrastructure for easy procurement, licensing, rendering and display of digital text documents. Basic principle of the invention and the provided infrastructure is to divide the execution of E-reading related processes such as procurement of documents, licensing, rendering and display between two different devices, a mobile unit on one hand and a base station on the other hand. In particular, a cost and energy-efficient variant of an electronic device is described that serves as mobile unit that is especially designed for the display of digital text documents within the provided infrastructure.

Abstract: A multitouch-capable touchscreen is realized in that a large number of pressure sensors are attached under a flexible surface and thus both the pressure distribution and also the deformation of the surface is measured. Local pressure maxima occur due to the flexibility of the surface material with associated deformation on contact. As several local pressure maxima can exist, it is thus also possible to identify a plurality of contacts simultaneously. It is possible from the strength of pressure and pressure distribution to determine the force that is used for pressing such that this information can also be used in the user interface. Such sensors can be produced very efficiently and inexpensively by printing an ink that changes its resistance under pressure onto PCB tracks designed as sensor surfaces. The PCB tracks and the sensor surfaces can also be printed out using an ink with as low a resistance as possible.
