The first category is data acquisition from sensors and processing them to predict the potential explosion. The second is tracking the miners and determine their current or immediately preen-USTelligent Community 12https://community.element14.com/challenges-projects/design-challenges/texas-instruments-safe-sound-wearables-design-challenge/b/blog/posts/safe-sound-wearables---trackable-safety-helmet-for-miners-3-communication-and-trackingThu, 09 Mar 2017 18:39:13 GMT93d5dcb4-84c2-446f-b2cb-99731719e767:4a1745b5-8090-41e1-93c4-ec0b0d9f0352msimon1<p>It looks like kits will be late because of an error with UPS<span>[View:/resized-image/__size/16x16/__key/commentfiles/f7d226abd59f475c9d224a79e3f0ec07-4a1745b5-8090-41e1-93c4-ec0b0d9f0352/contentimage_5F00_2.png:16:16]</span> It came to Germany then went back to the USA again.
