Attempt this previous-year question. The correct option stays hidden until you choose.
Consider the following actions:
1. Detection of car crash/collision which results in the deployment of airbags almost instantaneously
2. Detection of accidental free fall of a laptop towards the ground which results in the immediate turning off of the hard drive
3. Detection of the tilt of the smartphone which results in the rotation of display between portrait and landscape mode
In how many of the above actions is the function of accelerometer required?
Pick an option to check yourself.
• Correct Answer: C
• Accelerometers detect crash deceleration for airbags, free fall in laptops to park hard drive heads, and tilt for smartphone display rotation.
• All three applications rely on measuring acceleration and gravity orientation.
