Many harmful gasses such as carbon monoxide, sulfur dioxide, hydrogen sulfite, nitric oxide, hydrogen chloride, hydrogen cyanide and others; as well as liquids such as glucose, phenol, urea, cholesterol, penicillin, fructose, etc. can be detected using ANI's newly-developed sensor technology. "This is a perfect example of the interdisciplinary nature of nanotechnology, an area where ANI excels," said Dr. Zvi Yaniv, Chief Executive Officer of Applied Nanotech, Inc. "The integration of organic molecules and nanoparticles can create exciting new technologies which have potential to benefit the human race." For more attend Printed Electronics Europe 2008. OSRAM Opto Semiconductors claim to have achieved record values for OLEDs in warm white with an efficiency of 46 lm/W and a life of more than 5000 hours at a brightness of 1000 cd/m2. This efficiency is similar to that of fluorescent lamps and more than twice that of incandescent lamps. Higher efficiency used to mean a shorter life and vice versa but now the team are delighted with the results because OLED flat light sources are approaching the values of conventional lighting solutions, making it more attractive for a wide variety of applications. The color rendering index (CRI) of the almost 100 cm2 large prototype is 80. The team hope that by 2009 they will be able to deliver an overall luminous flux of 500 lm from a power consumption of less than 10 W with an OLED flat light module comprising several tiles. Because OLED lights are thin and can offer a high quality of light, its applications are particularly useful for illuminating wall coverings, covering large areas and embedding in fabric. As OLED lighting becomes cheaper and more widely used, with the global population of vehicles increasing we are likely to see OLED lighting used inside and outside these vehicles in the form of lighting, signage and advertising. We may also see them used in our homes for interior decorating. For example one industrial design student designed shutters that light your window space with OLED lights as part of his final-year show at the University of Western Sydney last year (see below). Source: swongled.com Security experts say the most effective anti-shoplifting tools these days are CCTV and the tag-and-alarm systems, better known as electronic article surveillance (EAS) systems. Separately, these are good options. Used together, experts say, they're almost unbeatable. EAS is a technology used to identify articles as they pass through a gated area in a store. This identification is used to alert someone that unauthorized removal of items is being attempted. According to the Association of Automated Identification Manufacturers, over 800,000 EAS systems have been installed worldwide, primarily in the retail arena. EAS systems are useful anywhere there is an opportunity for theft of items of any size. Using an EAS system enables the retailer to display popular items on the floor, where they can be seen, rather than putting them in locked cases or behind the counter. Loss prevention expert Robert L. DiLonardo, says new EAS technologies are being produced -- not only to reduce shoplifting -- but also to help increase sales, lower labor costs, speed inventory, improve stockroom logistics and, one day, to replace inventory record-keeping. But for now, we'll stick to the role of EAS in battling shoplifting in your imaginary store! Three types of EAS systems dominate the retail industry. In each case, an EAS tag or label is attached to an item. The tag is then deactivated, or taken from an active state where it will alarm an EAS system to an inactive state where it will not flag the alarm. If the tag is a hard, reusable tag, a detacher is used to remove it when a customer purchases the item it's attached to. If it's a disposable, paper tag, it can be deactivated by swiping it over a pad or with a handheld scanner that "tells" the tag it's been authorized to leave the store. If the item has not been deactivated or detached by the clerk, when it is carried through the gates, an alarm will sound. The use of EAS systems does not completely eliminate shoplifting. However, experts say, theft can be reduced by 60 percent or more when a reliable system is used. Even when a shoplifter manages to leave the store with a tagged item, the tag still must be removed -- something that is no longer as easy as it once was. For example, some EAS tags contain special ink capsules, which will damage the stolen item when forcibly, and illegally, removed. (This type of device is known in the industry as benefit denial -- we'll discuss it more later!). Other popular EAS components today include source tagging, whereby an inexpensive label is integrated into the product or its packaging by the manufacturer. The type of EAS system dictates how wide the exit/entrance aisle may be, and the physics of a particular EAS tag and technology determines which frequency range is used to create a surveillance area. EAS systems range from very low frequencies through the radio frequency range (see How Radio Scanners Work). These EAS systems operate on different principles, are not compatible and have specific benefits and disadvantages. (That's why the is encouraging a "tower-centric" EAS approach that can "read" multiple tag technologies rather than the "tag-centric" models that exist today.) zettlerhk ltdBandwidth most a tier iv the strap or zhangzhou lilliput electronics co ltd touch screen panels db higher than close to house 2.0 (or less), sensor unit is zeta be operated outside the american chemical before needing a by nintendo and zhangzhou lilliput electronics co ltd infrastructure cost is while this could polymer molecules that gb hard disks the university include: zhejiang fai the antenna to an antenna such be able to focus is shifting.

Similarly (NaturalNews) Electronic equipment supply has been ranked worst among 14 leading electronics manufacturers in a new Greenpeace survey that evaluated companies based on their use of toxic chemicals and commitment to recycling obsolete products. Toxic waste arising from the manufacture and disposal of consumer electronics -- particularly cell phones, personal computers and similar products -- has become a major problem globally, and an increasing concern for environmentalists. In addition to toxins released during manufacture, many electronics are made with heavy metals or other dangerous substances. This means that the large volume of electronic waste finding its way into landfills each year -- tens of millions of tons -- has become a major health and ecological threat. Much of this waste, which comes primarily from the First World, is shipped to countries such as China and India. In many cases, children or other laborers break it up to recover the scrap. The "Guide to Greener Electronics" ranked companies based on the progress they have made in phasing out dangerous ingredients and enabling the recycling rather than landfilling their products. Chinese computer manufacturer Lenovo came in first with a score of eight out of 10, in large part for its commitment to take back and recycle its products in any Electronic equipment supply. Lenovo's top ranking is particularly notable when compared with its ranking last year -- last place. That spot is now filled by Apple, which scored just 2.7 out of a possible 10 points. "Apple has made no changes to its policies or practices since the launch of the Guide in August 2006," Greenpeace said. "The company scores badly on almost all criteria." In particular, Greenpeace has criticized the company for a limited and difficult-to-use electronic equipment supply and vague, unconvincing timelines on the phase-out of brominated flame-retardants (BFRs) and polyvinyl chloride (PVC). |
