cycle is at most 20 ms. In addition, there must be enough overlap between adjacent frames. The frame length is determined based on the sampling rate. In the auto-correlation function of the frame, except for the first maximum value (at 0) and the maximum value Kmax = 114, the fundamental frequency of the frame is 16 kHz/114 = 140Hz. IV. Implementation of Self-correlation-based Pitch Detection Algorithm This course must be implemented in C ++. Then, in order to draw waveforms, I used opencv, w

-introduction/ Here we will briefly introduce some developments. One of the most important events was the fact that one Stanford team announced details of an algorithm that uses deep learning to identify skin cancer.

a more accurate service. This is not only conducive to cost reduction, but also a single point of breakthrough, in the future to provide core value, this value is a single product can not be achieved.In addition, the products introduced this year, including smart backpack and Sports Safety Watch, provide super power, off-grid sharing, location security, sports safety, ECG safety and other series of services to create a daily safe life standard concep

baseline instability due to high sweating. The reference electrodes such as the mastostomy and mandibular part can also cause ECG and vascular fluctuations. The record points near CZ can also be used as the reference electrode, and the M1 and M2 mastostomy locations can also be used as the EEG record points, which will help the system observe the EEG characteristics of the mastostomy.In addition, a ground electrode is required for the study of ERP ).

through esophageal peristalsis and liquid neutralization. Therefore, accurate evaluation of reflux requires a long period of monitoring. This check has been carried out in many hospitals, and the method is a bit similar to 24-hour dynamic ECG monitoring. People who receive the check also need to carry a small box 24 hours a day, but the electrode is not placed in the front chest, instead, they are placed in the patient's diet. The patient also needs

0 intro In the continuous spring rain in Hangzhou, I listened to Wang Feng's "Spring" Singing: "I still remember the spring many years ago. At that time, I didn't cut my hair, nor did I have a credit card or her, there is no home with 24-hour hot water. "Yes, how comfortable it would be if there is a home with 24-hour hot water. Imagine one day, before going home, I made a phone call or sent a text message to tell Aladdin that I was about to arrive home. At that time, I no longer worried about f

research will be an important cornerstone of the revolution. In the traditional patient management process, one of the duties of a nurse is to monitor the patient's condition. However, because we can not provide each patient with a nurse for direct supervision, the majority of patients are in the condition of ECG, breathing apparatus, such as electronic devices for remote monitoring. Nurses and doctors take turns to make rounds and spend a little ti

Function: The serial data is received after filtering, and before and after the filtering data display, the data can be saved to see the spectrum. This routine: 1, the serial port data received and have the protocol decoding (here everyone download, you can modify, or contact me to help modify) 2. Data after analysis, dynamic filtering 3, the data before and after filtering are displayed, easy to compare. File list FFT: Use this function for spectral analysis of the saved data. Myfilt

My graduation design and graduation design in those years I want to write it there. It has been more than a decade since I graduated from graduation. From my own design to helping students do it, I do it on a pay-as-you-go basis, after so many years, I have always felt that it is a bad thing that has never been recorded. As I grow older, I gradually understand whether the world is really good or bad. What is good or bad. 1. In my graduation project, I chose a Windows Monitoring System Based on W

Android phones generally use the client's role to actively connect the SPP protocol device (digital sensor connected to the Bluetooth module), the connection process is:1. Use Registerreceiver to register broadcastreceiver to get Bluetooth status, search device and other messages;2. Search using Blueadatper;3. Obtain the Bluetooth device information (such as name, Mac,rssi) in Broadcastreceiver's OnReceive ();4. Establish a Bluetoothdevice object through the MAC address of the device;5. Derived

Title: flashing alarm content using the color palette Author: favory. Peng (2010-05-11) In the monitor or other medical instruments, you will see that some parameters need to flash constantly. In the medical instruments, this indicates that the detection parameters are beyond the set alarm range. The blinking is to remind users that the parameters are too high, greater than or less than the lower limit (too long !!!); Generally, the blinking mode is similar to the following two methods: 1. disp
