Squeeze power efficiency out of processor-based designs -- Part one Design How-To 11/19/2008 Post a comment Processors play a key role in minimizing power consumption and extending battery life. Too often, designers limit their options for minimizing power consumption to little more than using low-power components. In fact, because processors can control the entire system, they in turn offer several ways to reduce and save on power consumption.
Webcast: Fundamentals of Motor Evolution Industrial Control DesignLine Blog 11/18/2008 1 comment See an overview of the evolution of motors and their electronic control, as well as an animation and video demonstrating the very first electric motor.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
