All Macintosh laptop computers today are equipped with a 3-axis accelerometer. This built-in accelerometer helps to freeze the hard drive and save its contents if the accelerometer / processor detect a potential impending free-fall of the laptop.

Through the Macintosh software framework, the accelerometer and the built-in camera can be accessed for display and recording of the dynamic accelerometer response and the camera image.

Employing the NEESit software RDV, response of the accelerometer may be displayed along with the synchronized video images. The response in the form and images and accelerations may be recorded for future display and review. The data can be later archived for use in various other applications.
