intel joule

Interesting post from The Verge on a new chip set from Intel called Joule that is intended to bring powerful computer vision capabilities to low cost, IoT types of devices. The application for using vision systems in architectural lighting control, interactive lighting installations, retail tracking/interaction systems, etc. continues to hold great promise – and as tech like this from Intel continues to drop the price/complexity of such hardware and IP networking becomes pervasive in lighting, there will be a tipping point when camera vision becomes the de-facto sensing standard.  Despite the fear of “big bother” always watching, the system capabilities and advantages of … Continue reading intel joule

lighting geekery: photoacoustic spectroscopy

I’m still amazed that after about 20 years specializing in lighting, I can still learn new things that lighting does.  Today’s crazy new thing: Photoacoustic spectroscopy.  Basically, light has enough energy in it to cause material to vibrate, generating acoustic signals that can be measured. I find this interesting because I’ve felt the affect first hand – holding my hand in the beam of a super powerful, crazy-narrow beam LED fixture (which doesn’t have any IR or UV energy in the beam), you can feel the power of the photons.  Mostly what I felt is probably thermal absorption in my skin, … Continue reading lighting geekery: photoacoustic spectroscopy
