  • Publication number: 20190135619
    Abstract: The invention relates to a method for producing optical components, wherein a first contact surface is formed by bringing a deformation element into contact with a carrier; and a second contact surface is formed by applying a functional element to the deformation element; said second contact surface at least partially overlapping the first contact surface, so that a deformation zone is formed by the area of the deformation element that lies between the overlapping areas of the two contact surfaces, wherein at least one portion of the deformation zone is heated and deformed in such a way that the functional element is deflected, in particular, shifts and/or tilts, and the functional element is joined with the deformation element during the process step of applying the functional element to the deformation element and/or during the process step of heating and deforming the deformation zone.

  • Patent number: 9802868
    Abstract: Disclosed is a ceramic sintered shaped body containing Y2O3-stabilized zirconia with a sintered density of at least 99% of the theoretical sintered density and having a mean grain size of <180 nm. The zirconia fraction of the sintered shaped body comprises tetragonal and cubic phases. Also disclosed is a process for the production of a ceramic sintered shaped body containing Y2O3-stabilized zirconia, which process comprises dispersion of a submicron powder and comminution of the dispersed submicron powder by means of grinding media having a diameter of less than or equal to 100 ?m to a particle size d95 of <0.42 ?m; shaping of the dispersion to form a body, and sintering of the body to form the sintered shaped body.

  • Patent number: 8645145
    Abstract: An audio decoder includes an 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 selects a mapping rule describing a mapping of a code value onto a symbol code in dependence on a context state described by a numeric current context value. The arithmetic decoder determines the numeric current context value in dependence on a plurality of previously decoded spectral values. The arithmetic decoder evaluates a hash table, entries of which define both significant state values and boundaries of intervals of numeric context values, in order to select the mapping rule. A mapping rule index value is individually associated to a numeric context value being a significant state value.

  • Patent number: 8645900
    Abstract: The invention relates to a method for influencing the selection of a type and form of a circuit implementation in at least one layer in a given integration task for at least one integrated circuit in a wafer composite, a module on a 2-dimensional carrier substrate, or a compact module. In one embodiment, a plurality of electric or electronic components are spatially arranged and to be electrically connected. Completed solutions x are stored in a database, and each of the completed solutions includes properties for the given integration task. The completed solutions define a destination space from which a solution is selectable by operating elements and determines a type and form of circuit implementation as a result of the given integration task, and aggregates the plurality of electric and electronic components in one of a plurality of integration technologies.

  • Patent number: 8232443
    Abstract: Method and device for inactivating a microbiologically contaminated mass containing solid particles. The method includes mixing the mass containing solid particles with a gelatinizing agent, transporting the mixed mass of solid particles and gelatinizing agent through a shaping device structured so that the mixed mass, at least in one area, is shaped to form a lamellar volume with a layer thickness of between 1 mm and 3 mm, and impinging the formed lamellar volume of the mixed mass with accelerated electrons.

  • Patent number: 8193821
    Abstract: The invention relates to a sensor system and several method for the capacitive measurement of electromagnetic signals having a biological origin. Such a sensor system comprises a capacitive electrode device (10), an electrode shielding element (20) which surrounds the electrode device (10) at least in part in order to shield the same (10) from interfering external electromagnetic fields, and a signal processing device (30) for processing electromagnetic signals that can be detected by means of the electrode device (10). According to the invention, additional shielding means (21) three-dimensionally surround the electrode device (10) and the electrode shielding element (20) at least in part in order to block out interfering external electromagnetic fields. The changes in the electrode capacity of the capacitive sensor system are determined with the aid of several methods which particularly use the inventive sensor system in order to take said changes into account when the test signals are evaluated.

  • Patent number: 6956249
    Abstract: The invention relates to a semiconductor component which is capable of blocking such as an (IGBT), a thyristor, a GTO or diodes, especially schottky diodes. An insulator profile section (10a, 10b, 10c, 10d, 11) provided in the border area of an anode metallic coating (1, 31) is fixed (directly in the edge area) on the substrate (9) of the component. The insulator profile has a curved area (KB) and a base area (SB), said curved area having a surface (OF) which begins flat and curves outward and upward in a steadily increasing manner. A metallic coating (MET1; 30a, 30b, 30c, 30d, 31b) is deposited on the surface (OF). Said coating directly follows the surface curvature and laterally extends the inner anode metallic coating. The upper end of the curved metallic coating (MET1; 30a, 30b . . . ) is distanced and insulated from one of these surrounding outer metallic coatings (MET2; 3) by the surrounding base area (SB) of the insulator profile (10a, . . .
