World's Smallest Thermal Camera

Norvegian-language TU Industry reports that Prox Dynamics' PD-100 world's smallest military grade UAV is equipped by the smallest to-date FLIR thermal camera weighting just 0.5 gram. A few months ago was their smallest camera 25 grams. The unit which is mounted in the PD 100 T weighs half a gram, says CTO and Prox Dynamics Entrepreneur Petter Muren. The whole drone with visible and thermal cameras weighs just 17.5g:

Eric Fossum Life Story

Trinidad Guardian publishes an article based on Eric Fossum's lecture on image sensors at the local university. After going through many interesting facts from the image sensor history, the article quotes Eric:

"Looking back at his work with the CMOS sensor, he boiled his learnings down into five brief sentences:

•Create the invention.
•Successfully commercialise it.
•Deliver on the promise compellingly.
•Sell the company.
•Defend the patents.

Best on the Market

Jeff Bier, BDTI president, publishes an interesting view on the computer vision IP cores market: "[Vision] processor core suppliers can choose to keep the details of their products confidential, disclosing them only to prospective customers under non-disclosure agreements. And core suppliers often prefer this approach, since it allows them to keep competitors in the dark about their products.

Over time, of course, information tends to diffuse, and competitors learn about each other's products. But this takes time, and in new markets competitors may remain ignorant about each other's products for quite some time.

...Given the lack of available information about competitors' products, I was surprised to find that nearly all of the suppliers are very confident that their product is the leader—and that it has a significant lead over competitors' offerings.

Reading many image sensor announcements, this is not that much different from the computer vision IP market.
