Smartphone detects atrial fibrillation with existing hardware

Smartphones can be used to detect atrial fibrillation with existing hardware, according to research presented at ESC Congress 2016 today. A low-cost application (app) has been developed that uses the phone's own accelerometer ...

Attention deficit disorders

Gyroscopes can help diagnose ADHD

The latest miniaturised movement sensors, incorporating both accelerometers and gyroscopes, can be used to provide an objective diagnosis of attention-deficit/hyperactivity disorder (ADHD), according to new research in the ...

Gyroscope

A gyroscope is a device for measuring or maintaining orientation, based on the principles of angular momentum. The device is a spinning wheel or disk whose axle is free to take any orientation. This orientation changes much less in response to a given external torque than it would without the large angular momentum associated with the gyroscope's high rate of spin. Since external torque is minimized by mounting the device in gimbals, its orientation remains nearly fixed, regardless of any motion of the platform on which it is mounted. Gyroscope works in situations when using magnetic compass is not possible at all (as in Hubble telescope). Due higher precision it is used to maintain the direction in the tunnel mining [2].
