Systems and methods are provided for automatically determining substitution chains that are valid during a rules-based ATP check for an order item. In one implementation, a system is provided that includes an interface for interfacing with a plurality of data storage devices in at least one of which a plurality of stock items are stored as data. The system also includes an execution memory storing software and a buffer for temporarily storing data. A processor coupled to the interface and the execution memory may carry out an availability check in which a replacement chain describing replacements is stored in the buffer. The replacement chain may be determined by one or more of rules defining substitutions.

A C-plate compensator is disclosed for compensating the residual A-plate and C-plate retardance of a reflective liquid crystal on silicon (LCoS) display or a transmissive liquid crystal (LC) display in a projection display system. The C-plate incorporates a form-birefringent coating, whose retardance magnitude can be adjusted by tilting with respect to the display panel (X-Y) plane. The tilted plate is rotated about the Z-axis by a prescribed amount from the slow axis of the display panel. Criteria are described for choosing the tilt and rotation angles such that the contrast of the display system produced by the compensated panel is optimized.

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 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.

Disclosed herein are techniques, systems, and methods relating to compensation of phase disturbances of a phase lock-loop during power ramp up or down of a power amplifier. More specifically, a phase lock-loop is described that is able to switch between type I and type II PLL modes depending on the power state of the power amplifier without introducing additional disturbances.

A feedback loop is used to determine phase distortion created in a signal by directly extracting the phase distortion information from a feedback signal using original frequency modulation information.

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.

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.

A method serves for the determination of the 3D coordinates of an object (2). A fringe pattern is projected onto the object (2) in the method. The light reflected by the object (2) is recorded and evaluated. To improve such a method, the fringe pattern is projected onto the object (2) by an imaging element (only FIGURE).
