    摘要: A apparatus and apparatus for compensating for video insertion loss due to transmission over long twisted pair cable lines is presented. Transmission of video over twisted pair cable is advantageous because of its superior cost advantage over coaxial cable. However, twisted pair cables have significant loss characteristics at the higher frequencies (i.e., broadband) compared to coaxial cables. At a transmitter station, the video signal is amplified in the high frequency region for possible skin effect losses thereby brute forcing the high frequency components to the receiving station. At the receiver station, the video signal is further compensated for diffusion line and skin effect losses. The total skin effect compensation applied in both the transmitter and receiver stations is such that the square root of frequency characteristics of skin effect losses is compensated for. Thus, at the receiving station, the high frequency compensation added at the transmitter to brute force the high frequency components to the receiving station may be removed if found excessive. Additionally, compensation is included to adjust for skew that may occur because of irregularities between the various twisted pairs used to transmit the individual video components. Non-minimum phase type filters are used to inject delay into the faster arriving signals so that they may coincide in phase with later arriving signals resulting in a true reproduction of the video.

    摘要: A method is proposed for generating a color profile using the determination of a mapping A′ of a device-independent process space Q(m) of dimension m, m being a natural number, to a device-dependent process space K′(n) of dimension n, n being a natural number, for a first set of specific parameters, which is distinguished by the mapping being represented by a concatenation of mappings, which includes a known mapping A from Q(m) to a device-dependent process space K(n) of dimension n, n being a natural number, for another set of specific process parameters, which differs at least in one element from a first set of specific process parameters; and either of a mapping TK from K(n) to K′(n) or a self-mapping TQ by Q(m).

    摘要: To obtain colorimetric values intended for regulating inking on a printing press (1) from a printed image (3) produced by the printing press (1), the printed image is measured calorimetrically in a plurality of pixels (4) with respect to a selected color coordinate system. The color vectors thus obtained for each pixel (4) are used to calculate color difference vectors to predetermined reference color vectors based on the same color coordinate system or reference color vectors determined from a reference printed sheet (3). The color difference vectors are multiplied by a weighting factor determined from the ink coverage of the pixels (4) and/or the color differences between the pixels (4) and their neighboring pixels (4). The color difference vectors weighted in this way can then be used as colorimetric values for regulating the inking on the printing press (1).

    摘要: For determining the ink coverages of printing inks involved in printing in one pixel of a print image, the pixel is scanned photoelectrically in the visible range of the spectrum and also in the near infrared range. Color coordinates of a perceptually approximately equidistant color system and at least one infrared value are formed from the scanned signals thus obtained. The ink coverages of the printing inks involved in the printing are then calculated from these color coordinates and from the minimum of one infrared value and are allocated to the pixel.

    摘要: The invention relates to a tool-spindle arrangement comprising a main spindle rotatably supported in a spindle housing and an electrical drive motor drivingly connected to the main spindle. The main spindle is constructed hollow to receive operating elements of the spindle arrangement. It is suggested that the motor shaft of the electrical drive motor itself is constructed as a main spindle.The main spindle is part of the drive motor. It is preferably constructed in two parts, namely, a spindle section and a motor-shaft section which, when connecting the drive motor to the machine, are coupled with one another. The motor-shaft section is also constructed hollow to receive operating elements, for example clamping members for chucking of the tool, air-blast pipes, cooling-medium pipes, etc.

    摘要: An electronic chess clock includes a generally rectangular casing atop which an elongate switching lever is mounted for pivotal movement about the center of the lever. A pair of electrochemical clockworks are contained in the casing for measuring and displaying time periods representing deliberation time of the chess players. A selected one of the two clockworks is actuated when the switching lever is pivoted downwardly at one end to actuate a microswitch associated with the selected clockwork. A common quartz-controlled time module provides time pulses to the selected one of the clockworks to insure that both of the clockworks operate at an equal rate. A manually actuable change-over switch coupled to the time module operates to allow the frequency of the time pulses to be selected so that the hand of the clockworks can indicate elapsed time on an expanded scale for greater accuracy in "short time" chess matches.

    摘要: In knitted goods, particularly pile-knit goods, with pile yarn tied into the loops and with weft elements extending at least over two-needle spacings, the pile-forming pile yarns are tied together only in every second course. This may be implemented by tying-in the pile yarns as loop jointly with the meshing yarn while weft yarns and dead piles are preferably tied as weft into the in-between courses. When tying the patterning piles as weft into every second course, dead pile and weft are also ties into these courses, while the in-between course will preferably consist only of the meshing warp yarn.
