In the solution of the invention, the built-in self testing circuit includes a memory for storing starting test values and expected test values, means for generating the input test values according to the starting test values, and means for determining a result of the structured test according to a comparison between the output test values and the expected test values.
Abstract: A mounting device for contactlessly-operating proximity switches includes a continuous cylindrical or cuboidal recess for holding the proximity switch which is formed by at least two legs. The mounting device can also include at least one through pocket, connected to the recess, into which an actuating tool can fit. The recess of the mounting device, when in a relieved state, has a smaller diameter than the proximity switch which is to be mounted. Additionally, the recess can be spread into an enlarged state by the actuating tool being positioned into the pocket and turned.

Abstract: Disclosed is an electrical contact having high electrical conductivity for a compact electromagnetic relay including an internally oxidized silver-oxide material which is prepared by subjecting an Ag alloy having a composition consisting essentially of, by weight, 5.1 to 9% Sn, 1.5 to 5% In, and 0.005 to 0.06% Bi, with the balance being Ag and unavoidable impurities, to an internal oxidation treatment and then subjecting to a heat treatment for diffusion, aggregation, and growth of precipitated oxides, wherein the internally oxidized silver-oxide material has a metallographic structure such that coarse grains of composite oxides are dispersed and distributed in an Ag matrix, the coarse grains of composite oxides being formed as a result of coarsening of ultra-fine grains of Sn-based oxides and ultra-fine grains of In-based oxides, which are precipitated by the internal oxidation treatment, by the heat treatment for diffusion, aggregation, and growth of the precipitated oxides.
Abstract: A graphic system includes a pipelined graphic engine for generating image frames for display. The pipelined graphic engine includes a geometric processing stage for performing motion extraction, and a rendering stage for generating full image frames at a first frame rate for display at a second frame rate. The second frame rate is higher than the first frame rate. A motion encoder stage receives motion information from the geometric processing stage, and produces an interpolated frame signal representative of interpolated frames. A motion compensation stage receives the interpolated frame signal from the motion encoder stage, and the full image frames from the rendering stage for generating the interpolated frames. A preferred application is in graphic systems that operate in association with smart displays through a wireless connection, such as in mobile phones.
Abstract: A device for filtering electrical signals has a number of inputs arranged spatially at a distance from one another and supplying respective pluralities of input signal samples. A number of signal processing channels, each formed by a neuro-fuzzy filter, receive a respective plurality of input signal samples and generate a respective plurality of reconstructed samples. An adder receives the pluralities of reconstructed samples and adds them up, supplying a plurality of filtered signal samples. In this way, noise components are shorted. When activated by an acoustic scenario change recognition unit, a training unit calculates the weights of the neuro-fuzzy filters, optimizing them with respect to the existing noise.
