48 results about "Abnormal pulse" patented technology

An abnormal pulse detection circuit in a receiver of the present invention includes: an incoming pulse edge detection circuit which detects the moment of rise of an input signal and outputs the result of the detection as an edge detection signal; a muting reference pulse generation circuit which generates a muting reference pulse based on the edge detection signal; a logic circuit which outputs a signal indicating a negative AND of the muting reference pulse and the input signal; a muting signal generation circuit which generates a muting signal from the output signal of the logic circuit; and a switching circuit which outputs the input signal or the muting signal. The receiver of the present invention can therefore reduce discomfort in hearing reproduced sound in case where a noise occurs in an audio signal due to a variation in pulse width.

The device can accurately detect the pulse of a user with high precision, adapting to a personal difference.

The application relates to the field of electronic technology, and discloses a data display method and electronic equipment. In the present application, the electronic device collects the pulse data within the first time period, and determines the ratio of the second duration to the first duration after determining that the pulse data contains abnormal pulse data. Wherein, the first duration is the length of the first time period, and the second duration is the cumulative duration of the abnormal pulse data. When the ratio is greater than the first preset value, the first physiological data is displayed, and the first physiological data includes the first physiological characteristic parameters, thereby ensuring that the physiological data displayed to the user is correct and improving user experience.

The invention provides a spectrum analyzing method of on-line detecting the number and content of inclusions in the steel. On the nitrogen condition, make predischarge and formal spark discharge between the metal sample and electrode pair, make lighting and light split analysis on the metal element and oxygen element, research and determine the critical value of metal element inclusion strength and that of inclusion-monitoring oxygen element strength, find out the abnormal pulse of metal element of each critical value of inclusion strength, and determine the number of the inclusions. By data processing and in comparison with the preset correcting curve of inclusion strength and content, determine and analyze the content of the inclusions in the sample. It can analyze the element content and fast analyze the content of inclusions in the sample, samples and detects the number and content of the inclusions in the refining procedure and controls the refining technique according to the detecting result, thus remarkably reducing the rejection quantity caused by the inclusions and enhancing the steel quality. It is applied to analysis on the number and content of the inclusions in the steel such as Al2O3, SiO2, MnO, CaO and MnS.
