  • Patent number: 6748804
    Abstract: A sensor element for electrically measuring the position of liquid levels, comprising a substrate (2) and a plurality of electrodes (3) that can be contacted individually and that are mounted on the substrate, characterized in that the electrodes comprise sensor-active partial electrodes (5) that are networked with electrical connections (7), with the partial electrodes of two respective electrodes always being positioned opposite one another, separated by a distance, as partial electrode pairs (11) and with the electrode pairs (8) thus formed recurring periodically over the length of the sensor. Quasi-digital measuring methods are derived from the behavior of the impedance of the electrode pairs, whereby the liquid level is measured by detecting a conductivity boundary in a capillary filling.

  • Patent number: 6700299
    Abstract: The present invention relates to an assembly of variable capacitance as well as to a method of operating the assembly. In the assembly, a variable capacitor is formed by a variable coverage or a variable distance of at least one first (4) and one second electrically conductive region (5). The first electrically conductive region (4) is configured on or in a substrate (1) and said second electrically conductive region (5) is configured on or in an actuator element (3) of a first micro-mechanical actuator (2). The actuator (2) is disposed on the substrate (1) in such a way that it can perform a movement of the actuator element (3) with the second region (5) along a surface of the substrate (1) at different positions relative to the first region (4), at which positions the second region (5) overlaps the first region (4) at least partly.

  • Patent number: 6684638
    Abstract: The invention relates to a micro reactor arrangement, particularly for a micro relay. It comprises a substrate (1) with two thermomechanical micro actuators (3, 4). In response to thermal stimulation, the first micro actuator (3) performs a movement in parallel with the substrate surface (2), while the second micro actuator moves in a direction orthogonal on the substrate surface (2). Both thermomechanical micro actuators are so disposed relative to each other that the first micro actuator (3), in the extended state, reaches under the second micro actuator (4). With these provisions, the first micro actuator (3) can be maintained in this position without supply of power when the second micro actuator (4) is de-energized. With the present micro actuator arrangement, one can achieve the advantages of a high activation force and long positioning travels of thermomechanical micro actuators for micro relays, without the necessity to supply energy for maintaining the individual switching states.

  • Patent number: 6655923
    Abstract: A micromechanical pump has a membrane (2) positioned above a substrate (1). The substrate is provided with a cavity (8) which is formed in an endlessly continuous shape (e.g., circular) to provide a channel for a drive fluid. A cover (9) is positioned above the substrate with the membrane being between the substrate and cover. The cover is provided with an inlet (11) and outlet (10). Electrodes (3, 4) are provided around the floor of the cavity. The electrodes are selectively actuated so as to attract selected areas of the membrane resulting in a gap forming between the cover and the selected areas of the membrane. The areas of the membrane above the non-selected electrodes form a seal with the cover. By selectively actuating the electrodes a peristaltic pumping action results in a pumped fluid traveling from the inlet, through the gaps and out the outlet.

  • Patent number: 6477940
    Abstract: The invention relates to a high-pressure piston cylinder unit, especially an injection pump or an injection valve for an internal combustion engine, and to a method for producing one such high-pressure piston cylinder unit. The high-pressure piston cylinder unit has a piston which is guided inside a cylinder bore and which is coupled to an actuating element. The piston is subjected to a high pressure differential. According to the invention, fine grooves which run very close to one another are configured in at least one part of the guiding surface of the piston. The grooves ensure hydraulic pressure compensation on the periphery of the guiding surface, thus reducing wear, and prevent leakage in a longitudinal guiding direction.
