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.
