@lucava: Re your question "Question: why are the different blocks not loaded with data at clock #1 ?"
Tis is a good question -- in fact they are all loaded at clock #1, the problem is that before clock #1 they all contain random "stuff" -- on click #1 we load the "good" values from the inputs into blovk A, and the random/unknown values from block A into Block B .. as we ckke on clocking things we get rid of the unknown / random values
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.
