The Grating is serving dual purpose, it is acting as a colour filter at the same time it is acting a lens as well. It would be interesting to further investigate to exactly differentiate this feature to exploit only one feature perfectly, without affecting the other.
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.
