The present invention provides a method for measuring and calibrating sample injection volume or mobile phase delivery rate of any type of micropumps or their integrated systems by using the direct proportion of the total activity (or mass) to the delivery rate (or volume) of a radiochemical nuclide with known activity in a certain time period. Also, the present invention may adjust the range of measurement and calibration from micro-liter (μL) to pico-liter (pL) or from μL/min to pL/min by selecting nuclide species and their concentrations from different liquid calibration radiation sources.

A language input architecture converts input strings of phonetic text to an output string of language text. The language input architecture has a search engine, one or more typing models, a language model, and one or more lexicons for different languages. The typing model is configured to generate a list of probable typing candidates that may be substituted for the input string based on probabilities of how likely each of the candidate strings was incorrectly entered as the input string. The language model provides probable conversion strings for each of the typing candidates based on probabilities of how likely a probable conversion output string represents the candidate string. The search engine combines the probabilities of the typing and language models to find the most probable conversion string that represents a converted form of the input string.

摘要:
A high etching selective layer and a light emitting structure are formed subsequently on a semiconductor substrate. Then, a p-type Ohmic contact layer and a metal substrate are formed subsequently on the light emitting structure. The semiconductor substrate and the high etching selective layer are removed. Next, an n-type electrode and a transparent conductive layer are formed adjacent to surface of the light emitting structure opposite to the metal layer.

A language input architecture converts input strings of phonetic text (e.g., Chinese Pinyin) to an output string of language text (e.g., Chinese Hanzi) in a manner that minimizes typographical errors and conversion errors that occur during conversion from the phonetic text to the language text. The language input architecture has a search engine, one or more typing models, a language model, and one or more lexicons for different languages. Each typing model is trained on real data, and learns probabilities of typing errors. The typing model is configured to generate a list of probable typing candidates that may be substituted for the input string based on probabilities of how likely each of the candidate strings was incorrectly entered as the input string. The probable typing candidates may be stored in a database. The language model provides probable conversion strings for each of the typing candidates based on probabilities of how likely a probable conversion output string represents the candidate string. The search engine combines the probabilities of the typing and language models to find the most probable conversion string that represents a converted form of the input string. By generating typing candidates and then using the associated conversion strings to replace the input string, the architecture eliminates many common typographical errors. When multiple typing models are employed, the architecture can automatically distinguish among multiple languages without requiring mode switching for entry of the different languages.

An active clamping circuit. The active clamping circuit is applicable to a DC-to-DC conversion circuit, and has an output terminal to supply an output voltage to a load. In the active clamping circuit, a determining circuit is coupled to the DC-to-DC conversion circuit to determine the output detects the output voltage and to output a first enable signal when the output voltage is higher than a first predetermined voltage. A voltage adjustment circuit is coupled to the determining circuit to pull low the output voltage according to the first enable signal. An inductor has a first end coupled to the output terminal of the DC-to-DC conversion circuit, and a diode is coupled between the inductor and an input terminal of the DC-to-DC conversion circuit as a conductive path to channel discharge current to the input terminal of the DC-to-DC conversion circuit.

摘要:
The branching decision for each node in a vector quantization (VQ) binary tree is made by a simple comparison of a pre-selected element of the candidate vector with a stored threshold resulting in a binary decision for reaching the next lower level. Each node has a preassigned element and threshold value. Conventional centroid distance training techniques (such as LBG and k-means) are used to establish code-book indices corresponding to a set of VQ centroids. The set of training vectors are used a second time to select a vector element and threshold value at each node that approximately splits the data evenly. After processing the training vectors through the binary tree using threshold decisions, a histogram is generated for each code-book index that represents the number of times a training vector belonging to a given index set appeared at each index. The final quantization is accomplished by processing and then selecting the nearest centroid belonging to that histogram. Accuracy comparable to that achieved by conventional binary tree VQ is realized but with almost a full magnitude increase in processing speed.
摘要:
A p-n diode includes a first electrode, a n-GaN layer on the first electrode, a p-GaN layer on the n-GaN layer, and a second electrode on a first portion of the p-GaN layer. A region of the p-GaN layer surrounding the electrode is a passivated region. Treating a GaN power device having a p-GaN layer includes covering a portion of the p-GaN layer with a metal layer, exposing the p-GaN layer to a hydrogen plasma, and thermally annealing the p-GaN layer, thereby passivating a region of the p-GaN layer proximate the metal layer.
