Byron Spice, Carnegie Mellon University Programmable Lights Prevent Glare, Improve Vision in Snow and Rain A smart headlight developed at Carnegie Mellon University's Robotics Institute enables drivers to take full advantage of their high beams without fear of blinding oncoming drivers or suffering from the glare that can occur when driving in snow or rain at night. The programmable headlight senses and tracks virtually any number of oncoming drivers, blacking out only the small...

With over 40 years as a leader in the industrial and commercial lighting industry Larson Electronics continues its commitment to providing high-grade lighting equipment to specialty markets with the release of a 300 watt LED security spotlight tower. This new light tower is ideal for security and corrections applications and contains a 300 watt LED lamp capable of throwing a spotlight beam up to 1,700 feet in length. Kemp, TX (PRWEB) July 10, 2014 The WAL-TSL-300W-LED security spotlight...

New Lenses For Nanoscale Light Beams Are Tiny Liquid Bubbles
2013-08-09 12:43:10

Penn State Bending light beams to your whim sounds like a job for a wizard or an a complex array of bulky mirrors, lenses and prisms, but a few tiny liquid bubbles may be all that is necessary to open the doors for next-generation, high-speed circuits and displays, according to Penn State researchers. To combine the speed of optical communication with the portability of electronic circuitry, researchers use nanoplasmonics -- devices that use short electromagnetic waves to modulate light...

Twisted Light Beams Could Enhance Internet Bandwidth Capacity
2013-06-30 07:42:43

redOrbit Staff & Wire Reports - Your Universe Online New fiber optic technology that transmits data along light beams that twist like a corkscrew rather than along straight lines could lead to increases in Internet bandwidth capacity, according to new research appearing in the journal Science. According to BBC News Science and Technology Reporter Jason Palmer, more data can be encoded in differently twisted beams because of the shape of the light. The concept had previously been...

Shining light between drops makes thunderstorm seem like a drizzle Drivers can struggle to see when driving at night in a rainstorm or snowstorm, but a smart headlight system invented by researchers at Carnegie Mellon University's Robotics Institute can improve visibility by constantly redirecting light to shine between particles of precipitation. The system, demonstrated in laboratory tests, prevents the distracting and sometimes dangerous glare that occurs when headlight beams are...

New Smart Headlights Dodge Raindrops
2012-07-07 07:58:39

Lee Rannals for redOrbit.com - Your Universe Online Ever tried to dodge rain drops in a downpour? Well, that´s exactly what one new set of headlights are able to do. Scientists at Carnegie Mellon University have developed a smart headlight that can predict where rain falls, and adjust the light beams accordingly. The researchers set out to develop a system that switches off rays of light that hit raindrops by using low-cost, off-the-shelf components. The team ended up with a...
