Abstract: The present invention relates to compositions and methods for selectively etching silicon nitride in the presence of silicon oxide, polysilicon and/or metal silicides at a high etch rate and with high selectivity. Additives are described that can be used at various dissolved silica loading windows to provide and maintain the high selective etch rate and selectivity.

Abstract: A flash memory device and method of making the same are disclosed. The flash memory device is located on a substrate and includes a floating gate electrode, a tunnel dielectric layer located between the substrate and the floating gate electrode, a smaller length control gate electrode and a control gate dielectric layer located between the floating gate electrode and the smaller length control gate electrode. The length of a major axis of the smaller length control gate electrode is less than a length of a major axis of the floating gate electrode.

Abstract: A heart rate detection method for calculating heart rate using heart sound from auscultation positions identified by a statistical approach utilizes a down-sampling and filtering process to acquire samples of heart sound from multiple auscultation positions of multiple testees and calculate heart rate with the samples, records time for calculating heart rate from each auscultation position of each testee and record the same from electrocardiogram, calculates a mean error and a standard deviation of the time to identify the auscultation positions allowing faster speed in heart rate detection, and applies a Bland-Altman difference plot and both a coefficient of determination and a Pearson's correlation coefficient to determine the degree of consistency and correlation of the heart rate measured from the multiple auscultation positions to identify the auscultation positions allowing generation of precise heart rate.

Abstract: The present invention provides an optical fiber monitoring system and method incorporated with an automatic fault protection mechanism. The optical fiber monitoring system includes a primary optical channel, a secondary optical channel, an optical channel fault examination device, a plurality of automatic fault protection devices, and a plurality of optical terminal equipments. When an automatic fault protection device detects a fault, it switches the connection of the optical terminal equipments from the primary optical channel to the secondary optical channel; meanwhile, a test optical channel is selected to be checked by the optical channel fault examination device.
