    摘要: Systems, methods, and other embodiments associated with an encoder. In one embodiment, a system includes an encoder having a code word generator and an appending logic. The code word generator is configured to generate code words based on input data and identify one or more short code words. A short code word has a length less than a length of a full code word. The appending logic is configured to append at least one dummy value to at least one of the short code words to convert the at least one short code word to a full code word. The encoder may further be configured to encode the converted full code word and store the converted full code word without the at least one dummy value in a storage medium.

    摘要: Systems and methods are provided for GF(q) iterative decoding. A decoder computes a plurality of R messages corresponding to a variable node of the decoder and forms decoder extrinsic information for the variable node by combining the plurality of R messages. The decoder stores the decoder extrinsic information in a memory during a first time period and retrieves the decoder extrinsic information from the memory during a second time period, the second time period occurring after the first time period. The decoder extrinsic information is provided to a soft detector.

    摘要: The present invention provides a novel one-step process for preparing an aqueous polymer dispersion by the free radical aqueous emulsion polymerization comprising mixing at least water, a dispersant, and an oil-soluble initiator; raising a temperature from the starting to the end reaction temperature while metering at least ethylenically unsaturated monomers and a water-soluble initiator into a reaction vessel, conducting polymerization of the monomers in the presence of the water-soluble initiator at a temperature up to the end reaction temperature, and when the temperature has reached the end reaction temperature, conducting polymerization by the oil-soluble initiator. The oil-soluble initiator is inactive at the starting reaction temperature and becomes more active as a temperature approaches the end reaction temperature at which the oil-soluble initiator is fully active.

    摘要: A measurement process or system transforms image data corresponding to images of an object to the frequency domain and analyzes the frequency domain data to determine a displacement of the object occurring between first and second images. Analysis in the frequency domain simplifies identification and handling of data expected to be noisy. In particular, frequencies corresponding to modes of vibration, lighting variation, or sensor error characteristic of a measurement system or frequencies corresponding to small magnitude frequency-domain data can be given little or no weighting in analysis that provides the displacement measurement. In one embodiment, Fourier transforms of shifted and unshifted images differ by a phase delay. A least square fit slope of the phase values associated with the phase delay can indicate displacements to accuracies less than 1% of a pixel width, thereby providing nanometer scale precision using imaging systems having a pixel width of about 1 μm.

    摘要: Measurement systems and methods extend the use of optical navigation to measure displacements smaller than a wavelength of the light used to capture images of an object measured. Nanometer-scale movements can thus be measured, for example, in equipment used for manufacture of integrated circuits or nanometer scale devices.

The first material layer is moved from a first position corresponding to the initial alignment state to a second position out of a field of view of the imaging system, and a first image of the second material layer is stored. The first material layer is moved back the first position to restore the initial alignment state. A second image of the first material layer is acquired. The second image and the stored first image are processed to determine the initial alignment state.
