Climate Change Odds Much Worse Than Thought

June 8, 2009 7:54 am | Blogs | Comments

The most comprehensive modeling yet carried out on the likelihood of how much hotter the Earth's climate will get in this century shows that without rapid and massive action, the problem will be about twice as severe as previously estimated six years ago - and could be even worse than that.

Obama 'optimistic' US can lead on climate change

June 6, 2009 10:00 am | Blogs | Comments

President Barack Obama said Friday he was increasingly hopeful that the United States can lead the way on climate change, six months before crunch global talks in Copenhagen. "I'm actually more optimistic than I was about America being able to take leadership on this issue, joining Europe, which over the last several years has been ahead of us on this issue," Obama said after talks with Chancellor Angela Merkel in Germany.

Toyota to start plug-in hybrid leasing

June 3, 2009 5:44 am | by YURI KAGEYAMA, AP Business Writer Yuri Kageyama, Ap Business Writer | Blogs | Comments

Toyota said Wednesday it will start leasing plug-in hybrid cars, that are even greener than its hit Prius, by the end of this year in the U.S., Japan and Europe.Toyota Motor Corp., the world's top automaker, will start leasing 200 plug-ins in Japan, 150 in the U.S. and 150 in Europe, mostly for rental, such as through special government-backed programs, it said in a release. Toyota will for the first time use lithium-ion batteries in the plug-ins. The batteries are already used in some cars but more common in laptops and other gadgets. Toyota hybrids now use nickel-metal hydride batteries. Using a lithium-ion battery will produce more energy, allowing the car to run more as an electric vehicle, but there have been some technological hurdles.

Utilizing Microcontrollers’ Low-Power Modes and Peripherals

June 2, 2009 10:13 am | Product Releases | Comments

Modern microcontrollers (MCUs) have a large variety of peripherals and features that can do a lot to help a design’s power budget. It is important for an embedded designer to have complete knowledge of a device so that he can fully utilize the modes and peripherals available to reduce the power consumption of a design.

Why MAX? – The purpose of WiMAX

June 2, 2009 9:40 am | by John Schwartz, Digi International | Articles | Comments

Whenever a new standard is adopted or starts to gain some ubiquity in the marketplace, I always have to ask, “So what? What does this new stuff give me that I don’t already have?” It’s an important question. If there is not any difference, then there is no reason not to just keep on using known and proven technologies. If there are differences, then knowing what these differences consist of can enable the appropriate business and design decisions.

The Climate is Right for Wireless Environmental Sensors

May 21, 2009 2:39 pm | by Sol Jacobs, Tadiran Batteries, www.tadiran.com | Articles | Comments

The effects of man-made climate change, once seen as a problem for future generations, is now viewed as an immediate threat, have led to significant technological investments to build a more sustainable future. From measuring the decline of snow packs in Antarctica and the North Pole, to measuring the impact of man-made dams on salmon migration patterns, to the development of systems that better predict natural disasters, remote wireless sensors are playing an increasingly critical role in advanced scientific technology.

Sweden Helps South Korea Convert Food Waste Into Biogas

May 21, 2009 7:20 am | by KELLY OLSEN, AP Business Writer | Blogs | Comments

The South Korean city of Ulsan lets water generated from processing food waste run off into the ocean, which can generate methane gas harmful to the environment. Now, with the help of a Swedish company, it is going to start converting that waste water into biogas, a type of clean fuel that can be used as power to heat buildings and even power vehicles.

Breaking the Bandwidth Bottleneck

May 18, 2009 1:19 pm | Product Releases | Comments

In carrier networks, the fiber plant uses Dense Wavelength-Division Multiplexing (DWDM) technology to combine more than 80 channels to transport the Internet traffic. Today, these DWDM channels are dominated by 10Gb/s line rate and channels are separated by a 50GHz spacing. With limited fiber, these 10G channels are the constraints at the critical fiber route now.

Wireless ICs in Automotive Security Applications

May 18, 2009 1:01 pm | by Gilles Cerede, Melexis Technologies, www.melexis.com | Articles | Comments

Let's start with a tough question: What is the difference between TPMS system and PKE system? Nothing! A TPMS system is placed inside the wheel and composed of a sensing device that measures temperature and pressure. When appropriate, for example before starting the engine, the car requests a measurement through a wireless link. If a pressure default occurs in one of the wheels, the car warns the driver through a signal on the dashboard. In PKE applications, the user carries a key fob device which contains an encoded identifier (ID). When the driver enters their car, the car requests the key fob ID through the wireless link. If the ID matches the ID stored by the car,

Solid State Lighting Could Learn From Betamax

May 1, 2009 6:59 am | by by Jason Lomberg, Technical Editor | Blogs | Comments

Conventional wisdom says that “early adopters” eventually bring new technologies into the mainstream. Thus, the effort to promote solid state lighting (SSL) has ample historical precedence. Back in the late 70’s, 80’s, and 90’s an epic battle was waged between Video Home System (VHS) and Betamax (Beta). One can draw lessons from the eponymous “videotape format war”—specifically, why technologies catch on (while others fade away)

Automated Storage and Retrieval Systems (ASRS) are at the heart of any fully automated warehousing system. As in all automated solutions, users demand nearly perfect, (i.e., 100%) availability and exceptionally fast operation at the lowest possible price point. While the raw speed of an ASRS along each axis of motion is limited by the selected drives’ components, modern sensor technology
