emPower glasses can be charged for reading

Posted in Apparel by Conner Flynn on February 15th, 2011

emPower wants to change the way that you use your reading glasses. Now they will need to be charged. The emPower glasses have tiny batteries inside, which power microchips that are capable of turning extra reading power on and off as needed.

The idea is that these would phase out bifocals, which older people often need. These glasses will use liquid crystals to simulate the lower part of the lens in a pair of bifocals. The crystals can change how the lenses refract or bend light, similar to how standard glasses do this with different levels of thickness.

Brother to replace AA & AAA with vibration charged batteries

Posted in Batteries by Conner Flynn on July 18th, 2010

Many devices have moved away from AA and AAA batteries in favor of lithium-ion rechargeable batteries. But for things like TV remotes, the use of AA and AAA batteries are still the norm. We have rechargeable versions of these batteries, but sadly most people still rely on the standard one use versions and throw them away.

Brother has an alternative for low-power devices. A new Vibration-power Generating battery (VpGB) has been created which can be produced in both AA and AAA sizes. It does not contain a certain amount of energy which gets discharged and then becomes useless though. Instead, shaking the battery generates power which can then be used immediately.
