puddingebola writes "Toyota has announced plans for a fuel cell powered car at the Tokyo Motor show. From the article, 'Satoshi Ogiso, the Toyota Motor Corp. executive in charge of fuel cells, said Wednesday the vehicle is not just for leasing to officials and celebrities but will be an everyday car for ordinary consumers, widely available at dealers. "Development is going very smoothly," he told The Associated Press on the sidelines of the Tokyo Motor Show. The car will go on sale in Japan in 2015 and within a year later in Europe and U.S."'"

New Smart Glasses Allow Nurses To See Veins Through Skin 124

Lucas123 writes "Epson and Evena Medical today unveiled a new smart-glass technology that allows nurses to see 'through' a patient's skin to the vasculature beneath in order to make intravenous placement easier. The Eyes-On Glasses System is based on Epson's Moverio Smart Glasses Technology, an Android-based, see-through wearable display launched earlier this year that allows users to interact with apps and games. The glasses use near-infrared light to highlight deoxygenated hemoglobin in a patient's veins and capture the images with two stereoscopic cameras. The cameras then project the vein images onto the see-through glass screens. The glasses can store the images and video and transfer them wirelessly to a patient's electronic health record, and they also come with dual built-in speakers for video conferencing."

Ask Slashdot: What's On Your Hardware Lab Bench? 215

While that's a bit dramatic, I've found that over the last 20 years my oscilloscopes have been 'on' less and less. Instead, I use a combination of judicious voltage measurements, a logic analyzer and a decent understanding of the documentation of the gadget I'm working on. Stuff is just more and more digital and microcontroller-based, or just so cheap yet incredibly integrated that there's no point in trying to work on it. (I'm thinking RC toys for example. Undocumented and very cheap. Doesn't work? Buy another.) While I still do old-school electronics like circuit-level troubleshooting (on old test gear), that's not where the majority of hobbyists seem to be. Yet one thing I keep hearing is how people want an oscilloscope to work on hardware. I think it's just not that necessary anymore. What I use most are two regulated DC lab supplies, a frequency counter, a USB logic analyzer, a USB I2C/SPI master, and a USB-RS-232 dongle. That covers a lot of modern electronics. I have two oscilloscopes, a 100MHz two-channel stand-alone USB unit and a 1960s analog plug-in-based mainframe that is a '70s hacker dream scope. But I rarely use them anymore. What equipment do hardware folks out there use the most? And would you tell someone trying to get into electronics that they need a scope?"

Not All USB Power Is Created Equal 240

jfruh writes "We've reached a point in our electronic lives where most of our gadgets draw power from a USB cable, and we have lots of USB ports to choose from — some of which live on other gadgets, some of which live on adapters that plug into your wall or car. But those ports supply wildly varying amounts of power, which can result in hours of difference in how long it takes your phone to charge. The Practical Meter, the product of a successful Kickstarter campaign, can help you figure out which power sources are going to juice up your gadgets the fastest."
