Abstract: A sensor according to the invention has an amplifier that is capacitively loaded vis-à-vis the ground by a container and by a medium contained therein and that has a capacitive feedback that is dimensioned in such a way that the amplifier only oscillates when the critical filling level has not been reached. According to the invention, the capacitive feedback is influenced by the container in such a way that the capacitive load of the amplifier input caused only by the container is countered. In this manner, it is achieved that the sensor responds only to the capacitance of the medium, largely independently of the magnitude of the container capacitance.

Abstract: A method for structuring of silicon substrates for microsystem technological device elements, wherein the silicon substrate is covered with an etching mask and wherein the structures are furnished with a predetermined etching profile in the micrometer region with side walls and an etching depth At. For the generation of a predetermined positive etching profile, the side walls of the structures are furnished with the defined slope angle ? of from 60 degrees to 88 degrees relative to the etching bottom and the structures are generated with an etching depth At in the micrometer region. Initially an isotropic etching is performed such that a mask under etching u is generated, wherein the mask under etching u is formed approximately equal to the etching depth At.

Abstract: The Invention relates to a load cell which is designed to be coupled a flat belt-or similar-type elements for lifting elevators or similar. The inventive cell comprises a cell body (1) and a casing (2) which can be coupled to one another. According to the Invention the solid, metallic cell body support the corresponding strain gage. In addition, three cylindrical pivots (5) project out from the body, said pivots comprising a smooth outer surface and having a length that is adapted to the width of the lifting belt (9). One of the smaller lateral faces (6a) of the essentially prism shaped casing is open such that it can be coupled to the cell body. Furthermore, the upper and lower faces of the casing are provided with opposing openings for the passage of the lifting belt during the operational mounting of the cell.

Abstract: A color display called a Resource Tepee depicting, at a glance, resource utilization across functions and over levels of an organization. The display is constructed by starting with a resource utilization matrix whose elements are resources utilized at each combination of function and level. A matrix of co-ordinates is computed using the resource utilization matrix. This matrix contains the nodes of the Tepee. Boundary lines to separate the colors of the Tepee are obtained by connecting co-ordinates in each column of the matrix of co-ordinates. Colors representing distinct functions are applied to the spaces between boundary lines to obtain the Resource Tepee.

Abstract: The invention relates to a preferably ferriteless inductive proximity switch having at least one transmitting coil, one oscillator circuit and at least two receiving coils arranged in the alternating magnetic field of the transmitting coil, whereby the transmitting coil and the receiving coil are arranged adjacent to each other on a printed circuit board, and also having an evaluation circuit connected to the receiving coil for evaluating the received signal of the receiving coils when a target approaches the proximity switch.

Abstract: The invention relates to a hollow molded part with a closed cross-section and a reinforcement, wherein the hollow molded part is formed as a single piece and exhibits a blank mold, with the first region (1) with a first starting outer diameter (D1) and the starting wall thickness (b1), and at least a second region (2) with an outer diameter reducing in comparison to the starting outer diameter (D1) and having an increased wall thickness in comparison to the starting wall thickness (b1), wherein the increased wall thickness forms a reinforcement.
