  • Publication number: 20180054256
    Abstract: An optical converter is to be simply and reliably monitored. Thereto, a circuit device including a measurement bridge with a measurement branch, a first comparison branch and a second comparison branch is provided. A conductor path loop of the converter can be integrated in the measurement branch. The first comparison branch has a first series resistance variable via a first active element. Similarly, the second comparison branch has a second series resistance variable via a second active element. The first and the second active elements are respectively controllable by the same control signal. The circuit device further has an evaluation circuit with a first comparator and a second comparator, the outputs of which form the control signal and at the same time an output signal of the circuit device in AND-gated manner. Each comparator compares a tap of its respective comparison branch to a tap of the measurement branch.

  • Publication number: 20170261304
    Abstract: In a position measuring device (5) and a method for ascertaining positions of an object (3) to be measured, at least one capacitive position measuring sensor (7) provides a position measurement signal (PM) relating to the object (3) to be measured and at least one capacitive reference measurement sensor (14) provides a reference measurement signal (RM). The measuring sensors (7, 14) are connected to a computing unit (8) which is embodied to calculate a position signal (P) to ascertain the positions from the position measurement signal (PM) and the reference measurement signal (RM). As a result of interfering influences being contained substantially equally in the position measurement signal (PM) and the reference measurement signal (RM) as an interference signal (S), it is possible to determine and eliminate the interference signal (S) during the calculation.

  • Patent number: 9222074
    Abstract: The invention provides a process for producing a three-dimensional tissue by cultivating eucaryotic cells by introducing the cells into a matrix and cultivating the cells within the matrix in a cell culture medium within a cell culture vessel under controlled dissolved oxygen conditions of the cell culture medium. The matrix contains a support containing an optical oxygen sensor, which is an oxygen-sensitive dye, which upon irradiation with an excitation wavelength changes its emission characteristics in dependence on the dissolved oxygen concentration in the surrounding medium, including a dye phosphorescing upon irradiation of an excitation wavelength, which phosphorescence is quenched by dissolved oxygen.

  • Patent number: 8696762
    Abstract: The present invention provides the use of spider silk threads for the production of tissue implants for medical use. A scaffolding matrix is provided for implantation, which matrix is comprised of spider silk thread and/or segments of spider silk threads which are cross-linked. The cross-linked spider silk thread segments essentially maintain a three-dimensional shape into which it is formed by pressing between molds. The three-dimensional shape obtainable by molding sufficiently stable to be used as an implant or for colonizing by mammalian cells while essentially maintaining the three-dimensional shape. In a further embodiment, the scaffolding matrix of cross-linked spider silk segments is at least partially covered by cells autologous or heterologous to the implant recipient. The matrix colonized with cells is obtainable by in vitro cultivation of isolated cells in suspension with the scaffolding matrix.

  • Publication number: 20120061453
    Abstract: A method for producing tailor-made sheet metal strips, in particular steel strips, in which at least two sheet metal strips of different material quality and/or sheet metal thickness are welded to one another along the longitudinal edge in a continuous process. In order for the sheet metal strips produced by such a method to exhibit a relatively high level of weld seam strength, uncoated sheet metal strips are used in accordance with the invention as sheet metal strips to be welded. The tailor-made sheet metal strip formed of the uncoated sheet metal strips as a result of welding is then coated.

  • Publication number: 20050071580
    Abstract: A memory system includes multiple memory modules, which communicate with a memory controller over one or more channels. When a memory module receives an initialization command from a processor or the memory controller, the memory module performs an initialization procedure of the memory locations associated with the memory module. In an embodiment, at least a portion of the initialization procedure is performed in parallel with the other memory modules performing initialization procedures. Each memory module may include a buffer module, which receives the initialization command, and generates and sends data packets with the initialization data to the memory locations. A memory module also can receive a test command from the processor or memory controller, which causes the memory module to read data from the memory locations, compare that data with expected data, and keep track of any errors that may occur.
