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 smart- phone 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?
(a) Only one
(b) Only two
(c) All three
The correct answer is (c). Accelerometers are used in all three of the actions listed.
In the first action, accelerometers are used to detect the sudden deceleration that occurs during a car crash. This information is used to trigger the deployment of the airbags.
In the second action, accelerometers are used to detect the free fall of a laptop. This information is used to turn off the hard drive before it hits the ground, which can prevent data loss or damage to the drive.
In the third action, accelerometers are used to detect the tilt of a smartphone. This information is used to rotate the display between portrait and landscape mode.
Accelerometers are a type of sensor that measure acceleration, which is the rate of change of velocity. They are often used in electronic devices to detect motion or orientation. Accelerometers can be found in a variety of devices, including smartphones, laptops, and cars.
