USB Condoms

1.   Ever heard of this term : USB CONDOM..first as I read about this though like some tech humour but it was not...it was for real.This device prevents accidental data exchange when device is plugged into someone else’s computer or a public charging station. This is achieved by blocking the data pins on any USB cable and allowing only power to flow through. This minimizes opportunities to steal your data or install malware on your mobile device.

2.  As I read this ,the term became ok :-) to discuss around in my blog here.So the basic Juicejacking attack becomes null and void by the use of a USB Condom.

"The simple board at its core carries only the current from the outside pins on a USB connector — which pass along the 5V needed to charge. The middle pins that would normally transmit data can’t, as there’s no circuitry to do so on the Condom. You’ll be able to confidently charge in public as long as you’ve got your USB Condom handy, safe in the knowledge that no juice jacker is going to mess with your precious device." from : http://www.geek.com

Charge cell phones by using Radio-Waves

1. Here comes another first from NOKIA...no more charging from your mobile chargers...no more that last minute search to find that hidden mobile charger....now charge from a mixture of 78.03% nitrogen, 20.99% oxygen, 0.94% argon, 0.03% carbon dioxide, 0.01% hydrogen, 0.00123% Neon, 0.0004% helium, 0.00005% krypton, 0.000006% xenon or more simply AIR!!!!!!

2. Nokia says that in a few years time, they will be able to charge cell phones by utilizing close radio waves. This conniving and shaking up technology could lead to brobdingnagian reductions in energy demand if every cell phone could pull a charge of juice out of thin air.

3. Researchers at the Nokia Research Centre in Cambridge in the UK are working hard on a technology that can harvest small amounts of energy from ambient radio and TV waves. The cell phone would pick up radio wave frequencies as low as 500 megahertz up to 10 gigahertz, which includes television broadcasts, microwave ovens, mobile phones, wireless LAN, bluetooth, GPS, and two-way radios. In theory, two circuits would be capable of receiving and then converting the free energy to an electrical current to charge the battery of a cell phone.

4. Hopefully, it would be enough energy to keep the phone charged in standby mode; although at first it won’t be adequate to charge the phone while in use, or to full battery capacity. So far, the device can collect up to 5 milliwatts of power, and the short term goal is to collect 20 milliwatts of power, which is just enough to keep the phone charged in standby mode. Ultimately, 50 milliwatts of power would be ideal and could help slowly recharge the battery.

5. This technology could be applied to other electronic equipment as well. Radio waves could be used to charge MP3 players, handheld devices, Kindles, portable game players, etc. Nokia isn’t relying on this type of technology alone to power their phones, they are also looking at integrated solar cells to work in conjunction with this new development. Deployment of this feature in Nokia phones is still at least 3 years away. We’ll be standing by with our waning cell phones waiting for word.
