Now, a smartphone with built-in thermal imaging

Once an expensive tool used only by law enforcement and the military, thermal cameras are now accessible to anyone with a smartphone and an accessory. But starting with Caterpillar's new rugged S60, thermal imaging sensors are starting to be built right into smartphones.

The first smartphone to feature an integrated thermal imaging sensor isn't exactly skinny, though. The new CAT S60 measures in at just slightly thicker than half an inch, and features a strengthened die cast steel frame inside, and exceed the military's 810G drop test specifications. In civilian terms, its housing and Gorilla Glass 4 display can easily survive a drop onto hard concrete from a height of over five-and-a-half feet.

The S60 also boosts the waterproofing prowess of its predecessors. By flipping a few switches on the front of the device, which seals off its speaker, headphone port, and microphone openings, the CAT S60 can now function underwater, for about an hour, at a depth of just over 16 feet.

So, in other words, you don't have to keep it hidden and protected in a pocket during rainy days on the job site. It is going to be available sometime from June this year.
