Abstract: In a known method for producing an emitter component with a reflector, a flowable aqueous SiO2 slip is produced using a slip method, and the slip is applied onto a quartz glass main part in the form of a slip layer. The slip layer is then dried and glazed, thereby forming a quartz glass layer which is more or less opaque and diffusely reflective. In order to produce an optical component with a reflective layer made of opaque quartz glass with increased reflective optical power, a method is proposed having the steps of: providing a main part with a surface which is at least partly coated with a reflective layer made of opaque glass, compressing a surface region of the reflective layer made of opaque glass, and applying a mirror-reflective layer on at least one part of the compressed surface region.

Abstract: A physical layer transceiver for a wireline channel medium includes a host interface to a host device, a line interface to the medium, encoding/decoding circuitry for interfacing between the host device and the medium, and adaptive filter circuitry coupled to the encoding/decoding circuitry. The adaptive filter circuitry includes a plurality of filter taps, each corresponding to a segment of the medium, and capable of being powered ON and OFF separately from each other filter tap. Adaptive control circuitry can power ON a first subset, fewer than all the filter taps, corresponding to segments distributed along the medium, monitor powered-ON filter taps for occurrence of interference events, and upon detection of an interference event at a particular segment to which a particular powered-ON filter tap corresponds, power ON one or more additional filter taps corresponding to one or more segments in a vicinity of the particular segment.

Abstract: A heating device for heating a powder during the production of a 3D shaped part. The heating device has an infrared (IR) lamp and a housing in which a construction chamber is provided. The construction chamber is bounded at the bottom by a construction platform for receiving the shaped part and is supported on a support plate. The IR lamp heats the powder during production of the 3D shaped part in the construction chamber. For ensuring an optimized heat transfer to the sintering or melting powder with a particularly homogeneous temperature distribution, a partition wall composed of an IR radiation transparent material is arranged between the construction chamber and the IR lamp.

The surface property is checked and/or determined as a function of the differently large parameter values and/or of the distribution of these differently large parameter values on the raster elements, and the result is output in Step c).

Abstract: A receiver circuit is disclosed. The receiver circuit includes a multi-PAM input circuit to receive a multi-PAM input symbol. The input symbol exhibits one of multiple threshold levels during a sampling period. The threshold levels correspond to a set of M-bit two's-complement values within a defined set of threshold values. An adaptive filtering circuit includes a first transcoder to transcode the set of M-bit two's-complement values to a set of N-bit values, where N<M. An adaptive filter operates to filter the set of N-bit values to generate a filtered set of data values. A second transcoder transforms the filtered set of data values to a second set of data values that corresponds to a set of filtered M-bit two's-complement values.

Abstract: A method for printing a printing designed as a color-tilting surface onto an object surface includes a) printing a relief structure having strip-shaped webs onto the object surface, the strip-shaped webs being spaced apart and raised relative to the surface and each having first and second side flanks, and b) conformal printing of a pattern with first color strips parallel to but laterally offset from the webs. As a result, the first color strips more strongly determine color, brightness and/or another visual, optical or wavelength-related property viewed obliquely from the first side flanks than viewed obliquely from the second side flanks. At least in step b) a digital printing technique carries out the printing to permit variable predetermination of at least the first color strip dimensions, positions and/or contours. A colored isotropic printing ink and/or printing compound is used as the printing ink and/or printing compound.
