    摘要: In a method for the 3D digitalization of an object with variable surface a plurality of camera pictures of partial surfaces of the object (4) are taken and put together for determining the 3D coordinates of the partial surface of the object (4). Camera pictures are taken of partial surfaces of the object (4), which overlap at their edges. For each camera picture the 3D coordinates of the associated partial surface of the object (4) are determined. The 3D coordinates of these partial surfaces of the object (4) are matched and put together by a matching method. Each camera picture is divided into subframes (1.1-1.9, 2.1-2.9, 3.1-3.9) which overlap at their edges and which overlap with the subframes of adjacent camera pictures. To the subframes (1.1-3.9), the associated 3D coordinates from the camera pictures are assigned. The 3D coordinates of the subframes (1.1-3.9) are matched and put together by a matching method. The method can iteratively be carried out several times. (FIG. 2)

    摘要: A device may include an oscillator circuit, a control circuit, a frequency detector circuit, and a processor circuit. The oscillator circuit may include a frequency control input to output an oscillator signal. The frequency of the oscillator signal depends on an input signal applied to the frequency control input. The control circuit is configured to apply a first input signal value, a second input signal value, and a third input signal value to the frequency control input. The frequency detector circuit is configured to detect the first frequency value of the oscillator signal when the first input signal value is applied to the frequency control input, a second frequency value of the oscillator signal when the second input signal value is applied to the frequency control input, and a third frequency value of the oscillator signal when the third input signal value is applied to the frequency control input.

    摘要: A sampling method is for an asynchronous sensor, in which sensor data are read out from a sensor element at a sampling rate and written into an output register and subsequently read out from the output register at an output rate. The output rate of the output register is increased by a programmable interpolation of at least two sampling values.

    摘要: The invention relates to a polarization compensating element (PCE) for a liquid crystal, e.g. liquid crystal on silicon (LCoS), display system manufactured using a linearly photo-polymerizable polymer (LPP) for orienting a photo-polymerizable liquid crystal polymer (LCP) film. To decrease the reflection, polarization conversion, and interference events in an LPP/LCP assembly the ΔN birefringence value of the LCP material is minimized. Dielectric coatings are added at various locations throughout the assembly for minimizing the amount of reflection, polarization conversion, and interference effects and for suppressing spatial retardance ripples.

    摘要: A vacuum valve comprises a conical sealing surface arranged at a valve body, a valve disk at which a conical sealing surface is arranged, and a sealing ring having a first sealing surface and a second sealing surface. The valve disk, the valve body and the sealing ring are made of metal at least in the areas of the sealing surfaces. The valve disk is constructed so as to be curved or angled considered in axial section through the center and encloses an angle of less than 90° with the closing direction in the unloaded state at least in a radial outer portion adjoining the sealing surface. The valve disk has an elasticity such that a displacement of the radial outer edge of the valve disk relative to a point in the center of the valve disk of at least 0.1% of the diameter of the valve disk in direction of the center axis of the valve disk is bought about in the closed position of the valve disk relative to the open position of the valve disk by an elastic deformation of the valve disk.
