An Android mobile device to detect concealed items in an automobile by measuring vibration. The mathematical formula frequency of vibration uses the mass M which affects the vibration. As mass of solid surface changes, so does the vibration. If difference in the vibration is detected between the inspected vehicle and empty vehicle that is the Normal Frequency, it may indicate concealed items. The Android device contains components needed to implement this invention. An accelerometer. A vibrator. A touch screen display. A computer operating system, Android, that runs Android Java software. SQLite, a computer database. A computer network connection to the internet using a wireless network. A sensor to provide the latitude and longitude location of the device during testing, through GPS, GLONASS, or NETWORK. The device also provides an electrical power source using the device battery, wall outlet electricity, or automobile charging cable connected to an automobile. |
