A Powerful Watch The Casio Databank has several applications. cinsky via Flickr
A tiny three-phase motor invented by Swiss researchers could be used to power a new generation of wristwatches, allowing them to work acer btp-58a1 battery as mobile phones, app devices and GPS units. Those activities generally require plenty of power, which can be cumbersome and costly — but a new microelectromechanical system will keep them juiced.
Researchers at the Swiss Federal Institute in Lausanne came up with a small electromagnetic three-phase motor that yields three times the energy output of a traditional motor.Three-phase electricity works by carrying three alternating currents that reach their peak voltages at different times — so the total amount of power is constant, rather than fluctuating in peaks and valleys like the sine wave of a traditional A/C sony np-fm50 battery setup. The concept requires three separate coils to carry the currents. But a triple coil takes up space, which is not what you want in a wristwatch. So EPFL researchers had to build an entirely new configuration.
In a news release, EPFL does not elaborate on the setup except to say that it involved creating an entirely new fabrication process, which can be scaled up to larger volumes. The motor’s fixed pieces can be etched on silicon plates, allowing faster production.
The researchers also had to integrate the watch’s command electronics with the moving pieces so it could tell thinkpad t410 battery time accurately, according to EPFL.
Ideally, efficient three-phase MEMS motors could be used to power a wide range of devices, many more than just cool wristwatches. But these guys are Swiss, so improving the future of timepieces is an understandably high priority.

tional that you’d actually wear them.
LG’s GD910, which nikon d70 battery went on sale in Europe last year, kicked off the trend. We’re looking forward to seeing this prime video-chatting, text-messaging watch stateside at this month’s Consumer Electronics Show, along with new models from Kempler & Strauss and others. All of them let you converse through built-in speaker-phones, à la Tracy, or maintain privacy by beaming sound to a Bluetooth headset. Fitting such versatility into thin cases required sony np-fh50 battery years of engineering to squeeze together parts that are usually separated. (Kempler & Strauss, for example, overhauled a standard cellphone circuit board several times to keep the cellular and Bluetooth radios from interfering nikon d70s battery with each other.) Look for upcoming models to pack even more features, like GPS and Web access, in even smaller packages.
Oh, and they tell time

Soon: Long Life
Most Bluetooth-equipped devices run on lithium-ion batteries, which require daily charging. Casio’s prototype uses a new, low-energy form of Bluetooth to pull caller ID and texts from your cellphone, so the timepiece runs for two years on one watch battery. The new Bluetooth canon nb-2lh battery standard, which will arrive next year, saves power by transmitting data intermittently, not continuously as it does now. We previewed the inPulse back in January at CES--it didn't even have a name at that point, but we were still pretty impressed.

Metawatch: Brian Klutch
As high-speed-cellular samsung slb-11a battery radios shrink to fit behind watch faces, your wrist could become a hotspot. The MetaWatch prototype, based on a concept by HP and built by Fossil, could one day create its own Wi-Fi network to share with nearby phones, tablets and other Web-ready gadgets. Similar watches may also have flash nikon d50 battery memory to store data--such as maps and calendars--for quick access.
