| + | [* black] Feedback from capacitors attached to the oscillating plates within the gyroscope is fed to an [link|http://en.wikipedia.org/wiki/Application-specific_integrated_circuit|ASIC] that multiplies raw data by the sensitivty, or gain, of the unit, which is the ratio of output to input of the sensor. |
|---|---|
| + | [* black] The sensitivity of MEMS devices is usually in mV/dps (or degrees per second), so the output of the oscillator (in mV) divided by the sensitivity (mV/dps) provides the angular rate applied to the package in degrees per second. |
| + | [* black] This data is used, for example, to turn the steering wheel of a car or to change the course of an aircraft in any of the iPhone 4's games. |
