Abstract: A 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 Baseline Frequency, it may indicate concealed items. The Mobile Device contains components needed to implement this invention. An accelerometer. A vibrator or speaker. A touch screen display. A computer operating system. 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.

Abstract: A system and method using an Android cellular telephone to detect hidden materials, or contraband, 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 baseline, it may indicate hidden materials or contraband. The Android mobile cellular telephone contains components needed to implement this system and method. 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 GPS sensor to provide the latitude and longitude location of the phone during testing The phone also provides an electrical power source using the phone battery, or wall outlet electricity.

Abstract: A system and method using an iPhone cellular telephone to detect hidden materials, or contraband, 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 baseline, it may indicate hidden materials or contraband. The iPhone mobile cellular telephone contains components needed to implement this system and method. An accelerometer. A vibrator. A touch screen display. A computer operating system, iOS that runs Objective C software. SQLite, a computer database. A computer network connection to the internet using a wireless network. A GPS sensor to provide the latitude and longitude location of the phone during testing The iPhone also provides an electrical power source using the phone battery, or wall outlet electricity.
