Bluetooth may seem the obvious next step in the remote's evolution, but there are reasons that infrared hasn't died out.

We’re all used to receiving data wirelessly, but transmitting power over the air has been much trickier. Now Korean engineers have demonstrated a new system that uses infrared lasers to beam power as ...

They will use their technique to produce detailed, color-based maps of individual cells and collections of cells - in microscopic and eventually nanoscale detail - that will be analyzed using ...

Mid-IR lasers provide the measurement capabilities needed to support accurate, non-invasive blood glucose analysis.

Former Xinjiang government engineer Nureli Abliz, who saw firsthand how surveillance technology flagged thousands of people in China for detention, even when they had committed no crime, is ...

The BBA-4000 is a solar powered wireless infrared break beam system that is simple to install and requires no wiring. The break beam sensors are powered by lithium ion batteries that are recharged ...

Researchers demonstrate the conversion of infrared images to the visible, using ultrathin and transparent semiconductor nanocrystals. The demand for detecting infrared (IR) light, invisible to human ...

850-nm device delivers a beam angle of less than ±1° Capable of projecting a 3-in.-diameter spot on a surface 10 ft away, the CLE333 850-nm point-source emitter uses a specially designed lens for a ...

As humans spend increasing amounts of time indoors, we lose access to the sun’s natural benefits. Recognition of season affective disorder has grown accordingly. While the actual occurrence of the ...
