摘要:
A mid-voltage variable-frequency driving system and a total harmonic distortion compensation control method are provided in this invention. The mid-voltage variable-frequency driving system includes a total harmonic distortion compensation unit. The total harmonic distortion compensation unit is used to perform an optimal adjustment on a reactive component reference value of a grid-side phase current, such that a harmonic component of the grid-side phase current may be reduced and a power factor of a three-phase switch-mode rectifier module within the mid-voltage variable-frequency driving system may be maintained.

A CRM system enhances intracardiac electrogram-based arrhythmia detection using a wireless electrocardiogram (ECG), which is a signal sensed with implantable electrodes and approximating a surface ECG. In one embodiment, an intracardiac electrogram allows for detection of an arrhythmia, and the wireless ECG allows for classification of the detected arrhythmia by locating its origin. In another embodiment, the wireless ECG is sensed as a substitute signal for the intracardiac electrogram when the sensing of the intracardiac electrogram becomes unreliable. In another embodiment, a cardiac signal needed for a particular purpose is selected from one or more intracardiac electrograms and one or more wireless ECGs based on a desirable signal quality. In another embodiment, intracardiac electrogram-based arrhythmia detection and wireless ECG-based arrhythmia detection confirm with each other before indicating a detection of arrhythmia of a certain type.

摘要:
The present invention provides a method and a reactor for removing organic matters by immobilized-enzymatic electrode coupled electro-coagulation. In the method, in a single electrochemical system, an enzyme-modified electrode is combined with electro-coagulation to synergistically remove organic matters from water. Certain electrochemical parameters are controlled such that a polymerization reaction is performed between hydrogen peroxide generated by a cathode reaction and organic matters catalyzed by the immobilized-enzymatic electrode. After the polymerization reaction, the organic product enters an anode chamber through a pump. The organic product is precipitated and removed by performing a reaction between the organic product and different hydrolysis products from the electro-coagulation through a coagulating/flocculating effect of compression of a double electric layer, adsorption and electric neutralization as well as precipitation capture. Ultimately, the object of removing the organic matters synergistically through the enzymatic catalyzed polymerization at the cathode and the electro-coagulation at the anode is achieved. The present invention has a strong selectivity for low-concentration toxic organic pollutants and a good effect in removing small-molecular hydrophilic organic matters, the addition amount of enzyme is low, the cathode and the anode are fully used, the cost is reduced, the operation is simple, and the applicable is wide, therefore, the present invention is applicable to a variety of water and wastewater containing organic matters, and the contaminated water.

Methods, systems, and apparatus for testing content rendering are described. A method includes receiving input specifying a change to a parameter relating to display of content in a webpage, in response to receiving the input, generating a test image of the webpage including the content, comparing a target image of the content with the generated test image to determine whether the generated test image includes the target image of the content, and selectively providing a failure notification based upon a result of the comparison.
摘要:
A confined pulsed laser deposition method and apparatus that includes an ablative coating between a transparent confinement layer and a backing plane, and a laser beam directed through the confinement layer to ablate the coating at generally ambient temperature and pressure, and using laser induced pressure to synthesize metaphase from the ablative coating. For example, diamond phase carbon can be synthesized from a graphite coating. The laser beam can be directed through a focus lens to control the final spot size, or through a beam diffuser to make the intensity more uniform. An XYZ-stage can position a desired target area of the ablative coating to be irradiated by the laser beam. The laser beam can have an intensity of less than about 6 GW/cm2, or less than about 4 GW/cm2. The laser beam can have an excitation wavelength of about 568 nm.
