For a fact, Saadany's quote in the last paragraph isn't the usual hype. Optical designs seem to have exponentially increasing cost curves as components are added, with the result that performance compromises are required to get anywhere near a price point. The result is sometimes mediocre performance, but sometimes the design just can't be produced economically. I'd like to see some of these designs, just out of curiosity, since I don't have any optical design issues at the moment.
What are the engineering and design challenges in creating successful IoT devices? These devices are usually small, resource-constrained electronics designed to sense, collect, send, and/or interpret data. Some of the devices need to be smart enough to act upon data in real time, 24/7. Specifically the guests will discuss sensors, security, and lessons from IoT deployments.
