NEC Improves Workplace Efficiency with AR Solution Utilizing Smart Glasses

NEC Improves Workplace Efficiency with AR Solution Utilizing Smart Glasses Tokyo, November 7, 2017 - NEC Corporation (NEC; TSE: 6701) today announced the development of an Augmented Reality (AR) solution to assist users with the selection of items through the use of smart glasses, a smart watch and new "ARmKeypad" functions. This solution enables users to perform tasks without having to look away from objects, making it ideal for use in manufacturing, logistics and other industries. Currently, NEC is carrying out demonstration tests at a hospital pharmacy and a manufacturing floor, where it has confirmed a reduction in workplace errors and working time thanks to the assistance of the new solution.

ORNL Superhydrophobic Glass Coating Offers Clear Benefits - Maybe Also for Lighting Optics

Schematic representation of the coated product and applications. The properties could also be useful in different lighting applications lke outdoor lighting, street lighting or for automotive headlights A moth’s eye and lotus leaf were the inspirations for an antireflective water-repelling, or superhydrophobic, glass coating that holds significant potential for solar panels, lenses, detectors, windows, weapons systems and many other products. The discovery by researchers at the Department of Energy’s Oak Ridge National Laboratory, detailed in a paper published in the Journal of Materials Chemistry C, is based on a mechanically robust nanostructured layer of porous glass film. The coating can be customized to be superhydrophobic, fog-resistant and antireflective. Read more »

Novel Nanoparticle Production Method Could Lead to Better LED Lights, Lenses and Solar Cells

Sandia National Laboratories researchers Dale Huber, left, and Todd Monson have come up with an inexpensive way to synthesize titanium-dioxide nanoparticles, which could be used in everything from solar cells to light-emitting diodes. (Photo by Randy Montoya) Sandia National Laboratories has come up with an inexpensive way to synthesize titanium-dioxide nanoparticles and is seeking partners who can demonstrate the process at industrial scale for everything from solar cells to LEDs. Titanium-dioxide (TiO2) nanoparticles show great promise as fillers to tune the refractive index of anti-reflective coatings on signs and optical encapsulants for LEDs, solar cells and other optical devices.
