Abstract: Known infrared radiators have a moulded body, which has a radiation surface that emits short-wave or medium-wave infrared radiation with a first peak emission wavelength. In order to provide, proceeding therefrom, an infrared radiator with an emissions spectrum which is well matched to absorption characteristics with a maximum around 2750 nm, and which furthermore can be operated with a high electrical power density, and with which the warming-up time in industrial applications, such as, for example, drying of inks, joining of plastics or bending of glass, can be shortened, according to the invention a radiation converter material is applied to at least a part of the radiation surface and, as a consequence of heating by the infrared radiation of the first peak emission wavelength, emits infrared radiation with a second peak emission wavelength which is of a longer wavelength than the first peak emission wavelength.

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: An audio decoder for providing a decoded audio information includes a arithmetic decoder for providing a plurality of decoded spectral values on the basis of an arithmetically-encoded representation of the spectral values and a frequency-domain-to-time-domain converter for providing a time-domain audio representation using the decoded spectral values.

The arithmetic decoder is configured to determine or modify the current context state in dependence on a plurality of previously-decoded spectral values. The arithmetic decoder is configured to detect a group of a plurality of previously-decoded spectral values, which fulfill, individually or taken together, a predetermined condition regarding their magnitudes, and to determine the current context state in dependence on a result of the detection. An audio encoder uses similar principles.

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.

Abstract: A method for checking a surface of an object, imprinted and/or structured in raster form, includes: a) using a digital image, which reproduces a replica of the surface, b) checking and/or determining a property of the surface or the replica using the digital image and/or the replica, and c) outputting a result with reference to the property. Step b) includes constructing and/or reconstructing a raster made from raster elements, using the digital image and/or the replica in which at least one raster element parameter can assume two or more, differently large size, brightness, and/or color parameter values, depending on the position of the corresponding raster element. 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 device for drying and sintering metal-containing ink on a substrate enables homogeneous irradiation of the substrate, has compact construction, and is simple and economical to produce. Optical infrared radiators have a cylindrical radiator tube and a longitudinal axis, and emit radiation having an IR-B radiation component of at least 30% and an IR-C radiation component of at least 5% of total radiator output power. The radiators are arranged in a module with their longitudinal axes running parallel to each other and transverse to the transport direction. They thereby irradiate on the surface of the substrate an irradiation field, which is divided into a drying zone and a sintering zone arranged downstream of the drying zone in the transport direction. The drying zone is exposed to at least 15% less average irradiation density than the sintering zone along a center axis running in the transport direction.
