An Awarepoint white paper describes critical factors required to maximize your RFID system’s return on investment.

Real-time location systems (RTLSs) are an increasingly important strategic capability for a variety of business applications. RTLSs allow organizations to efficiently identify and track the location of supplies, personnel, equipment, and other items in real-time, as a cost-effective operational management tool.

With the success early adopters have had with RTLSs, the question is not whether to implement, but which technology is best suited for the many applications that can benefit from location awareness. An Awarepoint white paper, “Considering a Real-time Location System? First Consider the 5 Critical Success Factors,” can help maximize your return on investment and ensure long-term success of your RTLS investment.

“The implementation of RTLS technology should pay for itself as a result of shrinking the incidence of misplaced equipment, decreased rental costs, and increased utilization of equipment,” stated Jason Howe, CEO of Awarepoint Corp.

The five critical factors outlined in the white paper to obtain maximum benefit include:

• Enterprise-wide coverage—because assets and people move throughout your entire enterprise, to achieve maximum benefit, your RTLS deployment must cover every square inch of your enterprise.
• Location accuracy—to affect the highest impact for your strategic initiatives, room-level accuracy is a clear critical success factor.
• Installation and maintenance—a minimally invasive solution that does not compromise your existing IT network, does not interrupt daily business operations, and can be installed in days or weeks, is vital. Maintenance impact for hospital staff should be considered as well. It shouldn’t take a team of IT professionals to keep the system running.
• Interoperability—your RTLSs should be supported by standards-based technology and should offer an open application programming interface so that it’s capable of providing location and status data to both your end-users and to third-party applications.
• Low risk—you should partner with a vendor vested in your success. Look for a flexible business model that doesn’t require a large capital purchase or long-term contractual commitment, and allows you to easily expand assets as needed.

Added Howe, “In hospitals particularly, RTLSs can play an important role in automation of common tasks—improving operational efficiency, increasing patient flow, and enhancing patient safety. Knowing the location, status, and movement of equipment and people can be used to improve hospital business processes and asset utilization, reduce capital expense and rental costs, and improve staff productivity.”

ZigBee is a low-power communication system using digital radios. It’s intended to be easier to work with than Bluetooth. Adafruit recently added an adapter board for Digi’s XBee product line and has put together a great how-to to show the devices potential. Using two XBee radios and adapters you can wirelessly program an Arduino board. This would be great if your Arduino was installed in an inaccessible area or maybe it’s over 100feet away from where you’re working. The radios do serial communication just fine. What the how-to covers is getting the reset line working so the Arduino can restart automatically after you program it. Once the radio pair is configured properly, it will pass the RTS line state directly from one device to the other.

AU Optronics Corp has unveiled a new LCD panel that doubles as a fingerprint scanner. Each pixel is equipped with 4 optical sensors, so a 320×240 screen would have a scanning resolution of 640×480. They have also experimented with different sensors, such as UV. You can see an LCD panel that detects and displays the UV index above. Why did they use a secondary display to show the data though?

[nmarquardt] has put up an interesting instructable that covers building RFID tags. Most of them are constructed using adhesive copper tape on cardstock. The first version just has a cap and a low power LED to prove that the antenna is receiving power. The next iteration uses tilt switches so the tag is only active in certain orientations. The conclusion shows several different variations: different antenna lengths, conductive paint, light activated and more.

Italian scooter-maker Piaggio has unveiled a plug-in hybrid three-wheeler it says will get up to 141 mpg and could be on the road as early as next year.

The gas-electric version of Piaggio’s funky but fun MP3 scooter uses a parallel hybrid system much like that in the Toyota Prius but advances the technology by adding an electrical cord. Although Toyota, General Motors and several other automakers are developing cars that can be charged from a wall socket, Piaggio’s timeline, if met, would make it the first in the world to mass-produce a plug-in hybrid.

Yokogawa Electric has released the DXadvanced R3 data acquisition and display station for networks.

The product is an enhanced version of the Daqstation series of paperless recorders designed for more efficient monitoring of production lines.

The DXadvanced has a built-in panel and offers integrated display, recording and communication functions.

In this season of specters and spooks, what could be scarier than a steel-winged robotic spy plane shaped like a bat? The aptly named COM-BATis a six-inch surveillance device that is powered by solar, wind, and vibrations. The concept was conceived by the US military as a means to gather real-time data for soldiers, and the Army has awarded the University of Michigan College of Engineering a five year $10-million dollar grant to develop it.

Company Intamac has launched its broadband home monitoring products and services with WoonVeilig in The Netherlands. The BT Home Monitor VP1000 is easy to install DIY wireless security alarm and monitoring system. First of all it’s a security system. So, VP1000 includes a security panel and various wireless sensors: motion, smoke and flood detectors. The security panel offers a few pre-defined mode for the home security and possibility to connect to the broadband Internet to have access from everywhere. Additionally wireless D-Link IP cameras can be connected to the system to allow monitor you home.

The price of BT Home Monitor VP1000 including Main Control Panel, 2 Wireless Movement Detectors, Wireless Door Contact and Remote Keyfob is £115.99. Additionally consumer should pay £5 per month for the access to his online account and includes the cost of all outbound voice call, sms text message and e-mail notifications from our monitoring service. Additionally £2.5 should be paid for monitoring 4 IP cameras.

The new Intamac security system looks very similar to AlertMe but offers more useful features then it. However, AlertMe is based on standard home automation protocol ZigBee which is much better that using some proprietary unique one (I couldn’t find any information aboutVP1000 protocol). In any case, those two systems show a new tendency in the DIY home security and monitoring systems.

Climate change is devastating the flowers of Walden Pond, picking off those species that cannot react to rising temperatures.

Comparing data meticulously gathered by Henry David Thoreau more than a century and a half ago with more recent observations, Harvard biologists report in the Proceedings of the National Academy of Sciences that more than a quarter of Walden’s plant species have already been lost. And an additional 36 percent are in imminent danger, including lilacs, roses and buttercups.

“It had been thought that climate change would result in uniform shifts across plant species, but our work shows that plant species do not respond to climate change uniformly or randomly,” said co-author Charles Davis, a biologist at Harvard, in a release.

The Walden study shows that even small changes in temperature can have outsized impacts on plants that are evolutionarily adapted to fulfill ecological niches. Together with changes seen in other locations, like the unprecedented pine beetle damage in the West, the new work suggests that finely tuned biological systems are having a difficult time keeping up with the rapid pace of human-induced climate change.

The average temperature around Walden has risen by more than four degrees over the last century as increasing greenhouse gas concentrations from burning fossil fuels changed the earth’s climate.

But the warming is not just mowing the forest down, it’s shaping it as some plant species thrive under the new global conditions.

“Most strikingly, species with the ability to track short-term seasonal temperature variation have fared significantly better under recent warming trends,” the authors write.

Although the design of the Walden study is simple, it depends on the value of Thoreau’s rare pre-industrial data.

“Whenever you have an opportunity to get a dataset where someone who has made very careful efforts to observe things in a systematic way, it gives you a snapshot of a particular time period and lets you make comparisons,” said Mark Schwartz, a world expert in phenology, the field of seasonal changes in living things, at the University of Wisconsin, Milwaukee.

Unfortunately, very few ecosystems have been recorded in such excruciating detail.

“We don’t have a large number of datasets of this sort,” Schwartz said. “Most of them are concentrated in Europe and in Asia. There are very few in North America.”

For example, Isabelle Chuine at France’s Center for Evolutionary and Functional Ecology, published a paper in Nature using detailed grape harvest records in Burgundy dating from as far back as 1370. Schwartz also noted that many European weather services record phenological data along with their weather measurements, while American weather stations do not. As a result, Americans know less about when our plants bloom than many other countries.

But Schwartz is trying to change that by empowering Americans to contribute their own Thoreau-style data. He’s the chair of the National Phenology Network, a new organization attempting to incorporate data from ecological stations, citizen scientists and other types of fieldwork.

Already, one of the NPN’s efforts — Project BudBurst — has marshaled several thousand people to track the timing of plant flowerings in their backyards as they shift due to climate change.

Their data could not only benefit scientists of the present and future, but could aid in providing Americans with direct evidence of climate change, helping to create the political will necessary to address the nation’s greenhouse gas emissions.

“When someone asks me about climate change, I say, ‘You can go observe it in your own backyard,’” Schwartz said. “If you want to see what’s happening, start taking records and see for yourself.”
