Strobe Light and Flashlight
- Strobe your device's screen and/or flash LED from 1 - 30 Hz. Strobing helps one to see objects vibrating too fast for the eye to see.
- Turn your device's screen and/or flash LED into a flashlight; this makes a conveinient flashlight during test setups.
- NOTE: Not all device's LED flash can be controlled by the VR Mobile app.
- Remotely control VibrationVIEW from within the VR Mobile App (while on the same network).
- Start/Stop tests
- View graphs
- Adjust amplitude and frequency
Max Acceleration Calculator:
- Calculate the maximum amount of acceleration that a shaker (from a database or user input) can output based on the mass added to the system.
- Convert Acceleration, Force, and Mass units to and from common units.
- Based on sinusoidal motion, calculate Acceleration, Frequency, Velocity, and Displacement by inputting any two of these values.
- Pick between two impact types: Plastic or Elastic, and the pulse type. Shock Calculator will find the remaining two values given two inputs: Acceleration, Impact Time, Velocity Change, and Height Change.
- Measure minimum, current, and maximum dB from your mobile device's microphone. Note: A device must have a microphone in order to use this feature.
- Measure minimum, current, and maximum acceleration in each of your mobile device's accelerometer axes.
- Zero out acceleration to calibrate for an uneven surface.
- See Vibration Research's building on Google Maps (or any other map application installed on your mobile device).
- Call, fax, or email VR directly from the app.
- Watch YouTube videos from VR.
- Visit VR's website.
- View VR's 9500 Revolution Vibration Test Controller, and the ObserVR portable DAQ.

This tool is powerful vibration meter tool.
It has the following features:
- shows vibrations in real time
- saves vibration data into SD card
- provides configurable sound alarm that may be used to:
- detect the earthquakes when you sleep
- detect if somebody opens the door when you sleep
It is recommended to use the battery charger when it works for a long time.
If you want to recommend the alarm feature that may recognize earthquake
We will also use this facebook page to keep you informed about the work progress and current activities and plans for the future.
This application comes with ABSOLUTELY NO WARRANTY.
There is a problem that occurs on some devices. Some devices may not provide the data when from the vibration sensor when the screen is off. This is an Android error.
We are trying to find a good workaround.
Send us the information if the application does not work, please
Very deep technical information http://code.google.com/p/android/issues/detail?id=3708
Modern phones and tablets have acceleration sensors for games, and to sense whether the device is held in portrait or landscape orientation. These sensors have become so good, they can be used to measure motion and vibrations with sufficient accuracy to determine the frequency spectra of those vibrations. accelomate is highly configurable in taking such measurements, and it calculates the spectra with a Fast Fourier Transformation (FFT; ideally the user should be somewhat familiar with the math and physics involved). It also displays all measurements and spectra.
Note that measurements and calculations require a certain amount of memory and CPU resources, so not everything might work on older (e.g. Android 2.x/3.x) devices. The quality of the spectra depends on the quality of the vibration sensor in your device. Our tests show that sensor quality varies over a wide range.
If you have specific questions on the inner workings, or feature requests, please don't hesitate to contact us.
The PRO version of accelomate features storing the spectra in a file for later analysis.

For example, it can be used
• To measure the vibrations produced during a plane takeoff or landing.
• To measure the acceleration of a vehicle.
• To measure the vibrations caused by a vehicle (indicates the comfort level of this vehicle).
• To measure the inclination of a surface.
• As a quick assessment tool to measure how intense are the vibrations produced by a product you are going to buy.
• In any other professional or even fun usages you can think of.
• Time Domain Analysis
Shows the magnitude of vibrations or the acceleration over time.
• Frequency Domain Analysis (PRO)
Displays a graph showing the measured frequencies on the X-axis and the magnitudes of each frequency on the Y-axis.
• Time Domain Parameters
Calculate features of the acquired vibration samples (Minimum, Maximum, Average, RMS, Variance, Skewness, and Kurtosis).
• Analysis can be done on the X,Y, and Z directions.
• Save snapshot of current analysis graph (PRO - available upon downloading our Spinner Jump game).
For any feedback, bug reports, or required features, please send an email at email@example.com.
Vibrations visualizes current accelerometer sensor data, performs a Fast Fourier Transformation (FFT) and displays the results in an histogram. The dominant frequency (peak of the histogram) is highlighted. In the settings the accuracy of the fft can be adjusted in a range from 0.0625 Hz - 1.0 Hz. Results are shown in a separate tab for each axis.
Warning: High accuracy of the fft causes heavy load on the cpu. It may disturb the results!
