If you want some level of lighting automation without smart bulbs, then dusk-to-dawn light bulbs might just be the solution. Here's a quick primer.

With the TSL2550 sensor, the intensity of ambient light can be converted to digital signals that, in turn, can be used to control the backlighting of display screens found in portable equipment, such ...

Built using polymer waveguides embedded in silicone, the technology could transform robotics, prosthetics, and next-gen ...

Researchers have developed a flexible optical touch sensor that can simultaneously detect the strength and location of ...

An overwhelming majority of handheld devices these days have ambient light sensors built into them. A large percentage of TVs and monitors do, too, and that proportion is growing. The sensors allow ...

In addition to their customary roles as indicators and illuminators, modern LEDs can also serve as photovoltaic detectors (reference 1 and reference 2). Simply connecting a red LED to a multimeter and ...

The ambient light sensor on your Dell business laptop adjusts the brightness of your screen according to light intensity picked up from the room. In a brightly lit office, the ALS increases the ...

Robotic surgery is no longer the stuff of science fiction. However, these robots can't really feel their way around -- the need for super-small mechanisms rules out existing approaches to touch.
