Abstract: The present application discloses a method for calibrating a parameter error of an electron probe microanalysis instrument. A one-dimensional grating standard template is prepared based on atom lithography technology. A theoretical grating period D of the one-dimensional grating standard template is calculated. The one-dimensional grating standard template is statically placed on a stage of the electron probe microanalysis instrument. The electron probe microanalysis instrument scans the one-dimensional grating standard template on the stage, performs image acquisition and measurement on a grid distance of the one-dimensional grating standard template to obtain a grating scanning distance measurement value L, and records a magnification ratio at this time. A calibration factor K under the magnification ratio is calculated according to D and L.

Abstract: In an imaging method, an image source transmits N image source light beams to a light beam deflector in K periodicities, where N is a positive integer greater than or equal to 2, and K is a positive integer greater than or equal to 1. The light beam deflector deflects transmission directions of the N image source light beams to a plurality of viewing areas, where the N image source light beams transmitted to the plurality of viewing areas are respectively imaged in a plurality of display areas.

Abstract: The invention provide systems and methods for management of digital media objects, comprising first and second client digital data processors (e.g., personal (or private) computers, laptops, dedicated music devices, electronic book readers, and so forth) that are in communications coupling with one or more stores (e.g, dedicated disk drives, flash drives, cloud storage, etc.). At least one digital media object (DMO) or copy thereof is stored in one or more of those stores and is accessible by at least one of the first and second client digital data processors.

Abstract: The invention provides, in some aspects, a digital commerce system that includes a first digital data device, a second digital data device and a third digital data device, each of which is connected to a network that provides at least intermittent communications coupling between the second digital data device and each of the first and second digital data devices. Redirection logic executing on at least the second digital data device effects storage on the third digital data device of a digital media object downloaded from the first digital data device to the second digital data device. The redirection logic accomplishes that in such a manner that storage of the digital media object on the third digital data device is effected before storage of that digital media object on the second digital data device—if the digital media object is stored to the second digital data device at all.

Abstract: A method and apparatus for additive range reduction are disclosed. A constant may be pre-stored in a look-up table (LUT), and at least one section of the constant may be retrieved from the LUT for generating a product of an input argument and the constant such that a precision of the product may be controlled in any granularity. For a trigonometric function, 2/? is stored in the LUT, and at least one section of 2/? may be retrieved from the LUT. The argument is multiplied with the retrieved sections of 2/?. The retrieved sections are determined to correctly generate the two least significant bits (LSBs) of an integer portion and a scalable number of most significant bits of the multiplication result. An output of the trigonometric function is generated for the argument with a fractional portion of the multiplication result based on two LSBs of the integer portion of the multiplication result.

Abstract: A method and a signal processing unit are proposed, for converting an asynchronous discrete-time signal to a synchronous discrete-time signal by performing sector-based timing recovery. The timing recovery includes aligning an initial portion of the asynchronous discrete-time signal to a first portion of a predetermined signal, and a later portion of the asynchronous discrete-time signal to a second portion of a predetermined signal. Optionally, the method and signal processing unit further perform sector based gain control, and sector-based removal of any dc component.
