    • The present invention provides a method for heat treating a polymer PTC composition to increase the peak resistivity of the composition making it especially well suited for high voltage applications. A polymer PTC composition having a melting point temperature Tmp is provided. The temperature of the polymer PTC composition is increased at a rate, r1, to a temperature greater than Tmp. The temperature of polymer PTC composition is held at the temperature greater than Tmp for a predetermined period of time. Then the temperature of the polymer PTC composition is decreased to a temperature less than Tmp at a rate, r2, wherein r2 is greater than r1.
    • 本发明提供了一种用于热处理聚合物PTC组合物以提高组合物的峰值电阻率的方法,使其特别适用于高电压应用。 提供了具有熔点温度Tmp的聚合物PTC组合物。 聚合物PTC组合物的温度以r1的速率增加到大于Tmp的温度。 聚合物PTC组合物的温度在大于Tmp的温度下保持预定的时间。 然后,聚合物PTC组合物的温度以r2的速度降低到小于Tmp的温度,其中r2大于r1。

    • Computer-implemented systems and methods for processing image data of a process-free plate are provided according to the present disclosure. The systems and methods may, generally, include a data acquisition step/means for receiving image data using one or more channels of a imaging system, each channel functioning to image the same target region of a process-free plate using a different wavelength of light, and a data processing step/means for filtering the image data using at least one of: (i) self-filtering, (ii) Fourier shrinkage and (iii) Wavelet shrinkage. When the image data is received using a plurality of channels, the received image data may advantageously be combined so as to optimize contrast-to-noise performance. The disclosed systems and methods may advantageously perform the operations of image de-noising, contrast enhancement, and thresholding, and may further involve compensation techniques, e.g., for minimizing distortion and blurring effects.
