A new Apple’s patent application entitled “Digital Radio Tagging Using an RF Tuner Accessory” has been revealed this week. It describes an HD Radio technology that may be later delivered to iPod touch and iPhone and gives its users greater flexibility in interaction with broadcast media. Nowadays HD Radio is a trademarked wireless radio format that allows FM and AM radio stations to simulcast analog and digital audio at the same time on the same channel.

While conventional accelerometer measures linear acceleration as a change of direction apart a change in velocity, a gyroscope measures angular acceleration, or in other words, a change in both direction and velocity at the same time. Thus the device can sense its rotation while ignoring hand jitters and linear movements, which is impossible for accelerometer.
