Siemens creating portable sensor to warn about asthma attacks, breathe deeply until it ships
We all wheeze a little from time to time, at least we do when we've fallen off the fitness wagon and are trying desperately to climb back on. For some it's a little more serious than that, and for those prone to dangerous bouts of asthma Siemens AG has a bit of hope. It's developed a portable sensor that can detect minute increases of nitric oxide in a patient's breath, particles that serve as a sign of an impending asthma attack. The user can then use that information to ingest the correct amount of anti-inflammatory meds. The device is said to be about the size of a cellphone, though unfortunately Siemens didn't specify a model. Like, are we talking a Veer here or a king-sized Nexus S? Inquiring minds want to know.
Siemens gurus hit 500Mbps with white LED lights, dare you to blink
You know what's better than wireless power? Nothing, frankly. You know what comes darn close? Wicked fast transmissions through thin air. Researchers from Siemens have just shattered their own record for wireless data transfer using white LED light, hitting a whopping 500Mbps while working in collaboration with the Heinrich Hertz Institute in Berlin. The old record sat at "just" 200Mbps, but the new speeds are helping to take Visible Light Communication from a hopeful technology to a serious contender in the space. These same researchers were also able to show that a system using up to five LEDs is capable of beaming out data over long distances at up to 100Mbps. We're told that the IEEE has been toiling tirelessly since 2007 to standardize activities in this field, and while a late 2010 completion date is currently being penciled in, we're not holding our breath. Anyone remember how long it took 802.11n to escape "draft?"[Thanks, Mademoiselle Y]
Siemens AG breaks network speed record
Data speed records are falling left and right these days but there doesn't seem to be any signs of the madness letting up, with Reuters reporting today that Siemens AG has joined the party, smashing the previous record for transmission rates over a single fiber channel using "exclusively electrical means." They maxed out at a speed of 107 gigibits per second before running out of steam -- that's reportedly a full 2.5 times faster than the previous record for a single fiber channel. What's more, they did it outside of the laboratory, using an existing a 100 mile-long fiber optic route in the U.S. According to Siemens, this record is particularly significant as it will reduce the need to split signals into a number lower data-rate channels in order to avoid bottlenecks, ultimately resulting in networks that are both faster and cheaper for customers. It looks like we'll still have to wait a while before we can take advantage of the speedy new technology, however, with the first prototype products based on it still a few years away.[Via Reuters/Yahoo News]
