Already known for its high-precision micro-electro-mechanical system (MEMS) accelerometers, gyroscopes and complete inertial navigation units (IMUs), Analog Devices Inc. (ADI) has upped the ante for high-precision with its invention of quad-differential iMEMS gyros, which combine four separate sensing elements to cancel out the effects of vibration, noise and other environmental stimuli. Look for ultra-precise MEMS sensors to revolutionize automotive crash prevention over the next five years. [via]

Starlino has a great article on using gyroscopes and accelerometers. [via]
I’ll try try to cover few basic but important topics in this article:
- what does an accelerometer measure
- what does a gyroscope (aka gyro) measure
- how to convert analog-to-digital (ADC) readings that you get from these sensor to physical units (those would be g for accelerometer, deg/s for gyroscope)
- how to combine accelerometer and gyroscope readings in order to obtain accurate information about the inclination of your device relative to the ground plane

This is a tri-rotor helicopter that has full autopilot. It has three gyroscopes, two accelerometers, three magnetometers, and a GPS module. All these modules are used in conjunction for an autopilot system. Check details on the link below. [via]
