New article simplifies motion measurements

To provide a more realistic interaction with the user, many embedded designers are incorporating controlled mechanical motion to their products. Most of these hybrid designs combine electronic circuitry, mechanical actuators, and microprocessor software to precisely coordinate movements and improve accuracies. One of the fundamental requirements for these projects is the precise measurement of velocity. A new on-line article entitled “Speed acquisition made simple” by Dr David Lin of the iC-Haus in Bodenheim, Germany provides a summary of velocity measurement techniques using magnetic sensors based on the Hall principle. If you plan to incorporate motion into your next embedded design Dr Lin’s expert analysis and detailed diagrams can deliver important background information and shorten the mechanical learning curve.
