摘要:
The invention relates to a method for producing transmission-enhancing and/or reflection-reducing coatings against or on substrates by flame coating. It is based on the object of suggesting a production method for anti-reflective coatings that works in an environmentally friendly manner with the least possible complexity in terms of work time and energy. It is comprised in that a silicon-containing precursor is thermally or hydrolytically decomposed by a hydrocarbon and/or hydrogen flame using an oxidant and is applied to the substrate directly from the gas phase as an SiOx(OH)(4-2x) coating, wherein 0

A gas burner, which is particularly suitable for flame treatment of substrates having large surfaces, e.g. for coating such surfaces in a combustion chemical vapor deposition (CCVD) process, includes a burner body with a gas supply connection and a nozzle plate, wherein the burner body and the nozzle plate constitute together a gas plenum and the nozzle plate constitutes a perforated wall section of the plenum. The nozzle plate includes a large number of nozzles extending from a plenum side to a flame side of the nozzle plate and it is made of a plurality of sheets which are arranged in a stack and extend substantially perpendicular or substantially parallel to the nozzle extension. The sheets include through openings, wherein the through openings of all sheets are at least partly aligned with each other, or they have a comb-like form.

A belt (1) comprises a tension layer (4), a first end portion (2) at a first longitudinal end, a second end portion (3) at a second longitudinal end, and an end connection for connecting the two end portions (2, 3). Here, the end connection comprises a first connection element (21), which is fastened to the first end portion (2), and a second connection element (31), which is fastened to the second end portion (3), wherein the first connection element (21) and the second connection element (31) are releasably interconnectable and are formed from an elongation-resistant material. The first connection element (21) and the second connection element (31) are each formed in one piece and, together with the tension layer (4), form a single neutral bending plane.

Methods and apparatus for performing image encoding and rate control as part of the image encoding process, e.g., a JPEG-2000 compliant image encoding process, are described. As part of the image encoding processes, rate control operations are performed based on rate statistic information at a point where encoded image data in selected for storage in a buffer and based on updated statistic information at a point where encoded image data is selected to be output from the buffer. The statistic information including overhead information used for rate control is also updated after formatting of data to be included in the output set of encoded image data to reflect overhead, e.g., header overhead, associated with formatting the data for storage. Encoding and rate control is applied on an ongoing basis, e.g., as portions of an image are processed, so that buffer size does not grow proportionally with the image size.

An apparatus for permeation or substance passage investigations, in particular for investigations on materials, for example polymers, plastic films, packaging, coatings, paper, wood (veneer) or the like, is operable independently of an analyzing device in terms of time and location. The apparatus includes a measuring cell, and a sample space and a measuring space defined by a sample which, when received in the measuring cell, divides the measuring cell into the sample space and the measuring space in such a manner that permeation or substance passage can take place solely through the sample.

Improvement is afforded in the recognition of wide-band data transmitted in the form of a data sequence to a network element of an analog, cellular network, notably a mobile radio set or a base station. The sequence includes a starting synchronization (DOT1), a word synchronization (WS), a data word (REP1) and number of repeats of a synchronization (DOT), a word synchronization (WS) and the data word (REP 1-REP 11). The network element recognizes, from received sequences, that a transmission of a sequence occurs when a starting synchronization (DOT 1) has been recognized, or alternatively when one of the further synchronizations (DOT) that is succeeded by a correct word synchronization (WS) has been recognized, and evaluates the data words (REP 1-REP 11) received each time subsequent to a recognized starting synchronization (DOT 1) that is succeeded by a word synchronization (WS), or received subsequent to a recognized further synchronization (DOT) that is succeeded by a correct word synchronization (WS).
摘要:
A low complexity visual masking method used as part of an image encoding process is described. The method is suitable for use in JPEG2000 image compression systems. Control weights used for rate allocation are generated based on integer order moments of wavelet transformed coefficients corresponding to a codeblock. The novel rate allocation weight generation method can, and in some embodiments is, combined with an apriori rate allocation algorithm, where allocation of bits to different portions of images is controlled as a function of one or more generated weights. The methods and apparatus of the present invention have the effect of increasing errors in busy areas of an image where they tend to be less noticeable and allocating a higher number of bits to less busy areas than some other systems, e.g., systems which attempt to minimize a mean squared error under a constraint of a user selected output rate.
