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.

Fraunhofer IIS IoT-Bus: The Secure Communication Bus - Not Just for Lighting

Fraunhofer IIS IoT-Bus: The Secure Communication Bus - Not Just for Lighting

The Fraunhofer Institute for Integrated Circuits IIS is developing the IoT-Bus with IPv6 support and integrated security concept. It is a communication bus based on EIA/RS-485 and the IEEE 802.15.4 standard, which enables a secure and reliable data transmission of measured values and control commands and connectivity to the Internet of Things. The IoT-Bus forms a cross-media communication protocol and unites the two worlds of WPAN and fieldbuses without complex protocol conversion. The novel technology IoT-Bus is developed as part of the SEEDs project.

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs

Intended for High-Performance Computer Chips - Maybe Also Useful for LEDs

The inner workings of high-power electronic devices must remain cool to operate reliably. High internal temperatures can make programs run slower, freeze or shut down. Researchers at the University of Illinois at Urbana-Champaign and The University of Texas, Dallas have collaborated to optimize the crystal-growing process of boron arsenide – a material that has excellent thermal properties and can effectively dissipate the heat generated in electronic devices.

When Nights Are No Longer Dark: Effects of Artificial Light at Night on Agroecosystems

When Nights Are No Longer Dark: Effects of Artificial Light at Night on Agroecosystems

In recent decades, artificial lighting has become an integral part of the modern world. While the use of artificial light at night (ALAN) greatly benefits people, it often has unintended, negative consequences for wildlife and ecosystems. In particular, the increasing use of LED lighting raises ecological concerns due to its high content of blue light, to which many organisms are sensitive. Dr. Maja Grubisic, Researcher at the Leibniz-Institute and Guest Lecturer at Free University Berlin discusses how ALAN can directly and indirectly influence agroecosystems, with potential consequences for food production and biodiversity. Given the current lack of integrative studies on this important topic, the better understanding of effects of ALAN in agroecosystems is urgently needed.

Hazard or Hope? LEDs and Wildlife

Hazard or Hope? LEDs and Wildlife

LpR 70 Article, page 52: The introduction and widespread uptake of LEDs as outdoor lighting has caused no small amount of concern amongst conservation biologists. The prevailing impression that LEDs are always blue-white is well founded as adoption of LEDs for streetlights were invariably high color temperatures and with the deterioration of phosphors the blue wavelengths penetrated even more. But LEDs do have characteristics that differentiate them from other light sources and may allow for the reduction of environmental effects of lighting on species and habitats: direction, duration, intensity, and spectrum. Travis Longcore, Assistant Professor at the University of Southern California's School of Architecture, sheds light on all these aspects.

Lighting and Emergency Dept. Clinician Wellness and Performance Improvement

LpR 70 Article, page 38: Short wavelength ("blue") light is known for its strong impact on humans covering "visual" function, wellness and performance of humans. Lighting has been recognized to have an effect on clinician wellness and performance as well as the occurence of medical errors. In a pilot study, Octavio L. Perez, Ph.D, WELL Accredited Professional and Adjunct Researcher at the Department of Population Health Science and Policy, and his team of scientists and physicians, Christopher Strother, Richard Vincent, Barbara Rabin and Harold S. Kaplan, from the Mount Sinai Hospital, New York, systematically investigated if and how a radically new lighting concept could improve wellness and performance in an emergency department.

ZigBee Alliance and Thread Group Join Force

ZigBee Alliance and Thread Group Join Force

The ZigBee Alliance, an association of companies creating, maintaining and delivering open, global standards for the low-power wireless Internet of Things (IoT), and the Thread Group, an organization focused on making Thread the foundation for the Internet of Things in the home and beyond, today announced that multiple members of both organizations have demonstrated prototypes that run the ZigBee Alliance’s universal language for smart devices on Thread networks. The demonstrations, shown privately at the Thread Group’s Members Meeting in November and set for public display in both organizations’ booths at CES, are a key milestone in their liaison agreement, and highlight accelerating momentum behind an emerging ecosystem of connected products that will interoperate over Thread IP networks using the widely deployed ZigBee language.
