In 1981 I got a Casio hand calculator: LCD display, running on one AA battery. I never turned the power switch off. I used it daily for a decade and after 25 years found it, and it was still functioning. Under a quarter century of grime. I recall over 30 years ago when the first chip was released for flashing an LED with a very short duty cycle. It was postulated that the batteries (way before Lithium-ion and when NiCad was the Gold Standard) would last longer with a very slight current drain. It seems they were right.
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.
