The debug system described in this patent specification provides a system that generates hardware elements from normally non-synthesizable code elements for placement on an FPGA device. This particular FPGA device is called a Behavior Processor. This Behavior Processor executes in hardware those code constructs that were previously executed in software. When some condition is satisfied (e.g., If . . . then . . . else loop) which requires some intervention by the workstation or the software model, the Behavior Processor works with an Xtrigger device to send a callback signal to the workstation for immediate response.

A referenceless self-clocking (n,k) bar code word allows conveyance of information without the need of any start and / or stop code pattern or other reference; a code word pattern is repeated at least in part without space therebetween according to a given n,k coding convention so that any k pair of adjacent data code elements sensed by any sensing means according to the n,k coding convention will consist of n units (e.g., bar code modules), thus allowing the data code elements of the code word to be decoded most accurately without any reference pattern. One application of this coding is on round or cylindrical objects like coins, casino chips and the like, and this coding is also well suited for linear or other coding applications wanting to convey coded information without the use of a start / stop code or reference pattern using n,k coding. This coding may or mayn't include error control, for example, as disclosed herein.

An efficient decoding of vector signaling codes is obtained using a circuit that ranks received signal levels, designates ranked values as representing particular code elements, and translates those particular code elements into a decoded result. An optimized ranking circuit combines analog crossbar switching of signal values with comparators that provide digital results. These elements may be repetitively tiled into processing arrays capable of larger ranking operations, or iteratively applied to selected portions of the data set under control of a sequencer or controller.

The invention is a kind of Chinese and foreign languages double-way automatic translation method which is based on the sentential form conversion and adopts the Chinese phonetic codes with the word as the unit, and it belongs to the automatic translation technology field. By the method we can translate Chinese and another language such as English to each other expediently, on one hand, it overcomes the present faults that all the Chinese-foreign languages translation can only be done by the Chinese characters and Chinese spelling because of that Chinese uses the connecting written Chinese phonetic codes by word which only adopts twenty-six Latin letters as the code element and includes Chinese sound, rhythm and tone to expresses information when translating, that Chinese characters and Chinese phonetic signs can not be compatible with ASCII codes completely and the malpractice that before every translation, the Chinese information that Chinese characters expresses has to be divided to single word, on the other hand, because of adopting the sentential form conversion method which bases on the lexical and the syntax system coincident with the goal language, to make the automatic translation method more exact than the traditional translation method, and the effectiveness better. However the inputting Chinese form is Chinese characters, Chinese spelling or Chinese phonetic codes, it can not only translates by the traditional method but also translate after changing the Chinese characters to Chinese phonetic codes, likely, if needed, the Chinese phonetic codes gotten after translation can not only express the Chinese information directly, but also be conversed to Chinese characters, Chinese spelling, Chinese sound, Chinese special person, Chinese localism or minority language sound.

The invention relates to a non coherent demodulation method, which belongs to the signal processing field, is used in Chirp spread spectrum technology demodulation, can reduce phase shift error, multipath time delay error and Doppler shift effect, and achieves better performance over multipath fading channels and IEEE802.15.4a S-V standard channels. The fundamental principle of the invention is: utilizing a Chirp signal as an impulse function in a proper fractional Fourier domain, i.e. fractional Fourier transformation achieves an excellent focusing ability to the Chirp signal sent by the CCS system. For the advantage of Chirp signal processing in fractional Fourier transformation, the fractional Fourier transformation can be used in CSS spread spectrum technology to demodulate Chirp signals with different modulation frequencies. The demodulation to CCS system is realized by implementing fractional Fourier transformation to the received base band data, and judging the code element by detecting the peak value of the focusing order. The method reduces the demand to frequency synchronization, needs no phase synchronization, and achieves better performance over multipath frequency selectively fading channels.

By the method, the user can quickly unlock the screen by touch operation, and the private information of the user can be protected through identity checking.

Implementations may relate to various aspects of modifying, or using, a coded bitstream, or to recovering watermarking information from data. In one implementation, a coded bitstream is modified to allow for the application of a watermark to the coded bitstream without changing the coding of any other syntax elements in the bitstream. This is performed by identifying conditions necessary to change a coded syntax element without disrupting the interpretation of subsequent coded elements. The coded syntax element is replaced with another coded value if the modified value generates the same decoding variables as the original value would have generated. Particular implementations focus on syntax elements coded using entropy coding, including, for example, Context-based Adaptive Binary Arithmetic Coding (CABAC). Regardless of the type of coding or watermarking, various implementations may provide for recovering watermarking information. Particular implementations recover watermarking information using detection data and feature information.

The invention provides a remote laser distance measuring system based on high-speed pseudo-random code modulation and photon counting. A basic principle is as follows: a high-speed pseudo-random code is used for modulating continuous optical fiber laser; modulated signal light is emitted through a transmitter-telescope system; and target reflection light is received by the transmitter-telescope system and enters a single-photon detector. A photon counting card is used for carrying out pulse identification and threshold value judgment on a signal output by the detector to obtain an echo code element sequence; and distance information is obtained by carrying out related calculation on an original pseudo-random code sequence. The remote laser distance measuring system has the characteristics of realizing high repetition frequency and high precision remote laser distance measurement.

A method for the non-contact measurement of a scene's 3D geometry is based on the concurrent projection of multiple and overlapping light patterns of different wavelengths and / or polarity onto its surfaces. Each location in the overlapping light patterns is encoded (code-word) by the combined arrangements of code elements (code-letters) from one or more of the overlapping patterns. The coded light reflected from the scene is imaged separately for each wavelength and / or polarity by an acquisition unit and code-letters are combined at each pattern location to yield a distinct code-word by a computing unit. Code-words are then identified in the image, stereo-matched, and triangulated, to calculate the range to the projected locations on the scene's surface.
