Organic Solar Cells and Light-emitting Diodes United

Organic Solar Cells and Light-emitting Diodes United

In the past 25 years of research on organic semiconductors, it was thought that organic solar cells and organic light-emitting diodes (OLEDs) could not be combined in a single device. A team of physicists headed by Prof. Koen Vandewal from Technische Universität Dresden has now succeeded in manufacturing an organic solar cell that simultaneously functions as an efficient OLED. Their findings were recently published in the internationally renowned journal Nature Materials.

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.

ALAN May Be Increasing West Nile Virus Spillover from Wild Birds

ALAN May Be Increasing West Nile Virus Spillover from Wild Birds

We're in the midst of summertime mosquito bite season and cities across the country are reporting a heightened number of West Nile Virus (WNV) cases. The house sparrow is one of the most common carriers of WNV in urban areas. Mosquitos feed off the infected birds and spread the virus to humans. New research finds house sparrows exposed to artificial light at night, such as what's used in parking lots, maintain higher burdens of WNV for longer than those who spend their nights in the dark.

Circadian-Friendly Light Emitters: From CCT-Tuning to Blue-Free Technology

Circadian-Friendly Light Emitters: From CCT-Tuning to Blue-Free Technology

Common levels of blue radiation are sufficient to disrupt the circadian cycle, calling for blue-depleted emitters in the evening. Most current solutions employ low-CCT and suffer from poor light quality. Aurelien David, chief scientist at Soraa explains the melanopic lumen and its possible sources of inaccuracy related to the uncertainty in assessing the circadian action spectrum. In addition, he also discusses the concept of a blue-free emitter with minimal melanopic lumen at very low CCT and how such a spectrum providing a good light quality can be optimized.

Tech-Talks BREGENZ - Dr. Octavio Perez, Adjunctant Researcher, Mt. Sinai Hospital

Dr. Perez received the LED professional Scientific Award 2018 for his paper on "Light and ED Clinical Wellness and Performance Improvement", which was published in LpR 70. The evaluation jury had the following to say about why they selected his paper: "The paper is based on the clear definition of the research question, hypothesis and objective of the research. The methodology of the screening study is described in detail and both subjective and objective parameters have been measured. Although Emergency Department lighting is a very special application, the paper provides interesting results." This interview provides background information on Octavio Perez, his work in general, his opinion on human centric lighting risks, opportunities and applications and how he became involved in this interesting research topic. Dr. Perez also provides additional details about the presented paper.

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.
