Write in front: This is my first coursework report for the first year of graduate school. After communicating with the teacher about the completion of the homework, there were also many small flaws. However, since I am in control of the direction and not in the mechanical direction, I did not continue. Improve the assignment […]
Tag: vibration
The scene mode sets vibration or silent mode, and changes to normal mode as the sound changes.
Getting the value of the scenario mode: AudioManager audioManager = (AudioManager) mContext.getSystemService(Context.AUDIO_SERVICE); final int ringerMode = audioManager.getRingerMode(); Conclusion: The ringerMode value will change after the user modifies the sound, and the vibration mode is changed to normal mode, silent mode or silent mode The process is as follows /frameworks/base/services/core/java/com/android/server/audio/AudioService.java private void setStreamVolume(int streamType, int index, […]
Ringtone/alarm/other sounds and vibration shielding modifications in Android system profile mode
Scenario mode description: frameworks/base/media/java/android/media/AudioManager.java RINGER_MODE_NORMAL: Normal mode All sounds are normal, including system sounds, incoming call ringtones, media sounds, alarm clocks, and notification sounds. RINGER_MODE_SILENT: Silent mode In this mode, there are no incoming call rings, notifications, system sounds and vibrations; alarm clocks and call sounds are maintained; most mobile phone media sounds are still […]
IOS-Swiftui background call ring vibration
IOS background ringing, implementation solution through UNNotificationServiceExtension Xcode creates UNNotificationServiceExtension target Process the specified notification content through the didReceive method of NotificationService Use UserDefaults(suiteName: self.groupName) for shared data transfer Create UNNotificationServiceExtension target Click Xcode-File-New-Target and the following options will pop up for filtering selections Here we choose Notification Service Extension Click Finish here to complete […]
The one-dimensional vibration signal is converted into a two-dimensional grayscale image, and the local binary pattern (LBP) is used to deepen the grayscale image features, and then CNN is used for feature extraction, and finally the softmax classifier and SVM are used for classification comparison (Python code, after decompression run directly)
Operation effect: The one-dimensional vibration signal is converted into a two-dimensional grayscale image, the local binary pattern (LBP) is used to deepen the grayscale image features, and then CNN is used for feature extraction, and finally the softmax classifier and SVM are used for classification comparison (Python_bee bilibili_bilibili Versions of all libraries used 1.

Millimeter wave radar method for measuring micron level vibration
chirp group generation Principle derivation One-dimensional FMCW distance FFT. The beat signal is continuously sampled within a period of time, and then the distance-time spectrum matrix is obtained by fast-time FFT. (There is code implementation later.) You can use reshape to rearrange long-term signals into a matrix. Pay attention to the setting of time td […]
Android Settings remove vibration function

Remove: Vibration and touch intensity options 4. Remove: vibration related options 5. Removal: Settings->Sound->Shortcut to prevent ringing->: There are two options: vibrate and mute, remove the vibration option 1. Removal: Settings->Sound->Other tones->: […]
Android ringtone multimedia volume, mute, vibration (with source code)
Introduction: Android provides an API that can control the native system. AudioManager is used to manage volume, mode (mute, vibration, vibration plus sound, etc. modes). You can use Vibrator and HapticFeedback to manage phone vibrations. I will explain it with a case study. First, I will talk about the volume control of the system gently, […]

iOS development-NotificationServiceExtension realizes real-time audio and video call notification ringing and vibration
iOS development-NotificationServiceExtension realizes real-time audio and video call notification ringing and vibration In the previous development, I encountered real-time audio and video call notifications. When the App is not opened or the App is in the background, the user needs to be notified. After the user clicks on the notification bar, whether to access the […]
