    摘要： The present application is directed to the use of photon migration analysis to provide a method of analyzing the diffuse reflectance, fluorescence, Raman or other types of spectra obtained from tissue. This procedure provides a means for processing spectral data such that the distortion in fluorescence spectra, for example, caused by the interplay of a variety of factors such as scattering, absorption, geometry and boundary conditions, can be precisely removed simply by measuring the diffuse reflectance spectrum as well as a second selected spectrum, such as fluorescence, and adjust the spectrum with the reflectance spectrum as described herein. By this procedure, the sample-to-sample variability is minimized. The intrinsic spectrum extracted by this procedure can be easily deconvoluted and provide quantitative information about the physicochemical composition of tissue. Analytical procedures for clinical diagnosis have been developed based on this method.

    摘要： A directional transmission mechanism, a directional sprocket apparatus using the directional transmission mechanism, and a pedal device using the directional sprocket apparatus are disclosed. The directional transmission mechanism includes a driving shaft, an output shaft, a co-rotating wheel, a reverse-rotating wheel, and a switching mechanism. The co-rotating wheel set drives the output shaft to rotate in a direction that is the same as that of the driving shaft. The reverse-rotating wheel set drives the output shaft to rotate in a direction opposite to that of the driving shaft. The switching mechanism switches the driving shaft to drive the co-rotating wheel set or drive the reverse-rotating wheel set to rotate, so as to enable the output shaft to rotate directionally. The co-rotating wheel set is connected with the driving shaft and the output shaft, and the reverse-rotating wheel set is connected with the driving shaft and the output shaft.

    摘要： Systems and methods to generate modified/refined user inputs based on the original user input, such as a search query, are disclosed. The method may be implemented for Roman-based and/or non-Roman based language such as Chinese. The method may generally include receiving an original user input and identifying core terms therein, determining potential alternative inputs by replacing core term(s) in the original input with another term according to a similarity matrix and/or substituting a word sequence in the original input with another word sequence according to an expansion/contraction table where one word sequence is a substring of the other, computing likelihood of each potential alternative input, and selecting most likely alternative inputs according to a predetermined criteria, e.g., likelihood of the alternative input being at least that of the original input. A cache containing pre-computed original user inputs and corresponding alternative inputs may be provided.

    摘要： Systems and methods of classifying user input are disclosed. The user input can be, for example, in the form of Roman characters. An ambiguous word (e.g., a word that is a non-pinyin word written in Roman characters and a valid pinyin word) can be identified in the user input. Contextual words (e.g., words adjacent to the ambiguous word) are classified as a pinyin context or a non-pinyin context. The ambiguous word is classified based on the context of the contextual words.
