Thermopile sensor theory

The story says "projects an infrared beam that monitors the radiation emitted from the surface of an object at a distance".

Actually, non-contact infrared temperature sensors simply monitor the black body radiation emitted by all objects to determine their temperature. They do not "project an infrared beam". All objects emit infrared photons, and the sensor picks them up. As the temperature of an object increases, the photons are no longer in the infrared and they become visible. We call this "red hot". If they get really hot, we call them "white hot" because the photons emitted are white in color. The shape of the spectrum emitted follows a charateristic curve, and if you can take measurements at at least two different wavelengths, you can calculate the temperature. There are also thermometers that make measurements of absolute energy at at one wavelength.

Regardless, all of the non-contact thermometers simply monitor photons emitted by objects. They do not project an infrared beam.

Kickstarted kicks up the tech funding

That's pretty good -- new technollogy supported by Kickstarter. I didn't realize the site was supporting this type of new technology. It's also interesting to see a that a device that needed $35,000 actually received more than $300,000.

With major product releases coming from big names like Sony, Microsoft, and Samsung, and big investments by companies like Facebook, 2015 could be the year that virtual reality (VR) and augmented reality (AR) finally pop. Here's take a look back at some of the technologies that got us here (for better and worse).
Good engineering designs are those that work in the real world; bad designs are those that don’t. If we agree to set our egos aside and let the real world be our guide, we can resolve nearly any disagreement.
The Industrial Internet of Things is bringing a previously reluctant process industry into the wireless fold. The ability to connect smart sensors to the Internet has spiked the demand for wireless devices in process manufacturing, according to the new study from ARC Advisory Group.
Enterprising Tesla Model S owner Steve Sasman seems to have figured out a way of recouping some of the cost on his car by renting the trunk out on AirBnB, the room/house rental website.
Everyone has had the experience of trying to scrape the last of the peanut butter or mayonnaise from the bottom of a glass jar without getting your hand sticky. Inventor Ron Jidmar thinks he has a solution to all of that nonsense with a flexible jar design that can be squeezed with one hand to lift contents from the bottom to the top of a jar or container, leaving the other hand free to scoop the contents out cleanly.
