You might think traffic light systems are fairly basic. After all, electric traffic signals first appeared all the way back in 1914. However, they have advanced significantly since their inception, ...

CU Boulder researchers have built high performing optical microresonators opening the door for new sensor technologies. At its simplest form, a microresonator is a tiny device that can trap light and ...

Most modern cars have tire pressure monitoring systems (TPMS), which will alert you if your tires need air. While most of the readings they give are accurate, they can still fail like any other part ...

Researchers have developed a highly sensitive light-based sensor that can detect extremely low concentrations of cancer biomarkers in the blood. The new technology could one day make it possible to ...

This Valentine’s Day, an art activation will transform parks across Los Angeles County, giving residents free access to experience sound and light-based works. The event is organized by Arup and the ...

During the NXT 2.0 era, Brooks Jensen, Fallon Henley (who joined in early 2022), and Josh Briggs formed an alliance that got them noticed very quickly. Their vignettes at Henley’s bar made it clear ...

Photoplethysmography (PPG) is an optical sensing technique that measures blood volume changes and underpins devices ranging from hospital-grade pulse oximeters to consumer wearables that track heart ...

Modern traffic light technology isn't just a simple sequence of red, yellow, and green. It's a complex detection system designed to manage traffic flow based on real-time demand. The very first "smart ...

The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for installation. The $50 sensor runs on two coin cell batteries so you don’t need a nearby power source for ...

Presence/motion sensors are one of the best ways to make automations feel more natural, but most of them run on batteries and eventually have to be swapped. That’s one of the main reasons I really ...

Distribution of quantum states generated by a central node to each node, phase encoding at each node, and estimation of arbitrary linear combinations of phases through local measurements. Precise ...
