585 results about "Normal values" patented technology

Normal values are expressed in ranges of numbers, and ranges vary for different age groups and from laboratory to laboratory. For example, a normal concentration of a substance in the blood might be expressed as 5 to 20 mg/dL. Although variations from normal values may be highly significant tools in the diagnoses of certain diseases,...

Method for generating heart beating waveform template and treating ventricular premature beat detection and device

The invention discloses a method for generating a template and detecting a premature beat, and a device. The method comprises the following steps: sequentially and respectively putting M waveforms for measuring a heart beating in N templates relative to the waveforms by sequentially performing a relativity comparison between the waveforms for measuring the heart beating and the N templates, wherein N is less than M; and taking the template which obtains most heart beating times from the first template to the N template as a normal template. The method for detecting the premature beat comprises the following steps: pretreating an inputted electrocardiogram signal to obtain a pretreated signal; extracting the feather parameters of the heart beating for measuring from the pretreated signal, wherein the feather parameters include the width of a QRS wave, an existing RR interphase and a related average RR interphase; obtaining the waveform of the heart beating for measuring from the pretreated signal, and calculating the association coefficient between the waveform of the heart beating for measuring and the waveform of the template; and according to judging conditions that whether the association coefficient between the waveform for measuring the heart beating and the waveform of the template is less than a set threshold and whether the feather parameters are deviated from normal values, judging whether a ventricular premature beat exists.

Open-loop control method and open-loop control system of permanent magnet synchronous motor based on space vector pulse width modulation (SVPWM)

The invention discloses an open-loop control method and an open-loop control system of a permanent magnet synchronous motor based on space vector pulse width modulation (SVPWM). To each given stator power frequency, the amplitude of stator voltage corresponding to the given stator power frequency is found through searching a two-dimensional vector table of the stator voltage and the stator power frequency, wherein the two-dimensional vector table is set according to a sectional voltage/frequency ratio curve in advance, that is to say, the ratio of the stator voltage and the stator power frequency in the two-dimensional vector table disclosed by the invention is not a normal value; and the ratio is different in different interval sections. In the prior art, as the voltage/frequency ratio is a normal value, when a load changes, a motor is out of step easily so as to cause overcurrent to the system. In the method disclosed by the invention, the sectional voltage/frequency ratio can guarantee the motor to adapt to the change of the load, reduce the consumption of the motor and improve the efficiency. In a constant power area, phase compensation is introduced, so that weak magnetic control is realized by using the regulated phase, and weak magnetic speed improvement is realized.

Dynamic threshold analysis method for operation index of IT system

The invention relates to a dynamic threshold analysis method for an operation index of an IT (Information Technology) system. The method comprises the following steps of: 1, inquiring historical change conditions of the operation index; 2, calculating a normal value interval R of the index under the current time granularity on the basis of a normal distribution principle, wherein the upper limit of the normal value interval is marked as an RU, and the lower limit of the normal value interval is marked as an RD; 3, connecting the RUs of all time granularities to be used as a dynamic threshold upper base line, and connecting the RDs to be used as a dynamic threshold lower base line; and 4, judging newly collected operation indexes under the current time granularity, wherein if the newly collected operation index is greater than the RU, the condition is the too-high-value abnormity, and if the newly collected operation index is lower than the RD, the condition is the too-low-value abnormity. The dynamic threshold analysis method has the beneficial effects that defects of a static threshold are overcome; and the historical operation rule of the operation index is intelligently studied, the normal value range of the operation index in different time points is calculated, and the dynamic threshold base lines are generated to be used for the monitoring and the analysis of the operation index. The dynamic threshold analysis method has the beneficial effects that mass manual operation is not needed; the calculation quantity is small; and the analysis is accurate, so that the operation and maintenance labor cost can be greatly reduced, and the monitoring coverage range and the accuracy are improved.
