  • Patent number: 7782927
    Abstract: An arrangement for generating a transmission clock signal and a reception clock signal is proposed in which only a single voltage-controlled oscillator is used, the reception clock signal being generated by phase-adjusting means whereas the transmission clock signal is generated directly by the voltage-controlled oscillator. Cross-talk between a plurality of voltage-controlled oscillators can be prevented in this way. Also, various measures are proposed for optimizing a circuit of this kind.

  • Publication number: 20090177832
    Abstract: The invention relates to multi-computer systems, wherein each computer (100, 200, . . . , N00) comprises a central processor (101, 201, . . . , N01) and working memory (103, 203, . . . , N03). According to one aspect of the invention, the “Internal High Speed Interconnect” (104, 204, . . . , N04) is extended beyond the internal limits of the computer and impinges upon the “High Speed Switch” (1). If need be, a single data conversion is performed in the High Speed Switch (100, 200, . . . , N00), specifically at the High Speed Interconnect Interface, and from that point the data is transferred through the “Switching Matrix” in a manner analogous to the state of the art.

  • Publication number: 20070224013
    Abstract: A self-drilling anchor for use in a friable material comprises a body having an axis, a flanged rear end, a drilling front end and a generally cylindrical portion therebetween having an outer surface with a thread disposed thereon, wherein the body forks, beginning at a predetermined distance from the flanged rear end, into a first leg and a second leg, the first leg extending forwardly into a drilling tip, wherein the first leg may have a generally rearward facing shoulder angled obtusely outwardly with respect to the axis, wherein the body has an axial bore for receiving an elongate fastener, the axial bore extending substantially through the flanged end and leading to the generally rearward facing shoulder, wherein the anchor is adapted so that the first leg pivots apart from the second leg when the elongate fastener deflects the generally rearward facing shoulder and the predetermined distance is selected to increase pullout strength when the first leg is pivoted apart from the second leg and the anchor i

  • Publication number: 20070120933
    Abstract: A printing system includes a first image applying component configured for applying one or more primary colorants to print media for rendering an image. A second image applying component is configured for applying a second colorant, such as black colorant, to print media for rendering an image. A first pathway conveys print media between the first image applying component and the second image applying component. A second pathway bypasses the first image applying component for conveying print media which is printed by the second image applying component. Where an image is to be rendered With the primary colorants and optionally also black, the print media is directed on the first pathway to both the first and second image applying components. Where an image is to be rendered only with black colorant, the print media may be directed to the second image applying component via the bypass pathway. In this way, during black printing, the first image applying component can be placed in a standby mode.

  • Publication number: 20060251886
    Abstract: The invention relates to electronic devices whose electronic properties can surprisingly be improved to a significant degree by inserting at least one crosslinkable polymeric buffer layer, preferably a cationically crosslinkable polymeric buffer layer, between the conductive doped polymer and the organic semiconductor layer. Particularly good properties are obtained with a buffer layer in which crosslinking is thermally induced, i.e. by raising the temperature to 50 to 250° C. Alternatively, crosslinking can be radiation-induced by adding a photoacid. Moreover, such a buffer layer can be advantageously applied by means of printing techniques, especially inkjet printing, as the ideal temperature for the thermal treatment is independent of the glass transition temperature of the material. This avoids having to rely on material that has a low molecular weight, making it possible to apply the layer by means of printing techniques.

  • Publication number: 20060147095
    Abstract: A method and system capture an image of the interior of the eye, for example the retina and determine whether the captured image is sufficient to provide data for identifying an individual or animal before attempting to generate the identification data. If the captured image is not sufficient, the method and system automatically capture another image of the interior of the eye.

  • Patent number: 6975141
    Abstract: The invention relates to an LVDS driver for small supply voltages, particularly of less than 2.0 V, for producing a differential output signal (Pout, Nout), having a pull-up transistor (P3, P4) and a pull-down transistor (P1, P2), respectively, for switching the output voltages which are output at the outputs (Pout, Nout). An optimum switching response and hence an undistorted differential signal can be produced by virtue of the pull-up and pull-down transistors (P1–P4) being in the form of PMOS transistors.

  • Patent number: 6924668
    Abstract: The present invention is a converter stage for converting a differential logic input signal and a corresponding common mode differential logic signal each having a first single-ended logic signal and a complementary second single-ended logic signal into a single-ended logic output signal. The converter stage comprises a first and a second differential stage each having a first and a second MOS transistor and a first and second current source for the differential stages. According to the invention the current sources are controlled by the voltage level which is centered between the mid-potentials of the common mode level differential logic signal and the mid-potential of the differential logic input signal.

  • Patent number: 6836162
    Abstract: To generate an output signal (11) the frequency of which is twice the frequency of an input signal (1, 2), a delayed signal (3, 4) which is delayed relative to the input signal (1, 2) by a quarter of the latter's cycle period is generated and the output signal (11) is then generated as the difference between the rectified input signal (1, 2) and the rectified delayed signal (3, 4). The input signal (1, 2) and the delayed signal (3, 4) are advantageously rectified by using differential signals each comprising a positive component signal (1, 3) and a negative component signal (2, 4). A respective one of two transistors connected in parallel is driven by a positive component signal (1, 3) and a negative component signal (2, 4) in such a way that a positive half-wave causes the relevant transistor (5-8) to conduct and the relevant transistor (5-8) blocks in a negative half-wave.
