Autonomous Driving Experts Weigh 5G Cellular Network Against Dedicated Short Range Communications – IEEE Spectrum

http://spectrum.ieee.org/cars-that-think/transportation/self-driving/autonomous-driving-experts-weigh-5g-cellular-network-against-shortrange-communications-to-connect-cars What is the right communications technology for self-driving connected cars? Telecom operators want it to be their 5G network. But it is not the only technology…

Microphones and their use

A microphone is an acoustic-to-electric transducer or sensor that converts sound into an electrical signal. Electromagnetic transducers facilitate the conversion of acoustic signals into electrical signals. Most microphones today use electromagnetic induction (dynamic microphones), capacitance change (condenser microphones) or piezoelectricity (piezoelectric microphones) to produce an electrical signal from air pressure variations. There are many different
