On flashers, the device could warn vehicles approaching that a police vehicle has someone pulled over up ahead (so driver can change lanes, slow down. May help protect officers from being hit while working).<br> I don't even want to think about the militaries' applications because thought control is what I'm expecting. Scary times up ahead for all.]]></description><dc:creator><![CDATA[All thieves should be slaughtered]]></dc:creator><pubDate>Mar 12th 2007 10:02AM</pubDate></item><item><title><![CDATA[Comments on Matsushita demonstrates data beaming with visible light]]></title><link>http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</link><guid isPermaLink="true">http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</guid><description><![CDATA[I'd say it's probably "purportedly streaming information along at "optical fiber speeds,"" because that's exactly what fiber optic is, however fiber optic uses the fiber to transport the light stream so it can go around curves, longer distances, etc. To me this "idea" is absolutely useless because fiber optic already uses visible light and makes it useful, and IR already beams while in line of sight. Flashing a light is nothing new, but doing something new and useful with it is rare. The only thing I see this offers is a faster than IR, un-tethered data stream, however I'd think that depending on how the wavelengths affect it, I don't see why IR couldn't be ramped up other than the fact that it's never been needed because it's main use has been very small communications. As it gets faster, each flash of the light is faster, and therefore you're going to end up having to mount the sending and receiving devices because shaking at all would throw off the signal. IR is slow enough that even with a little shake it works fine and that's what it's meant to be for. Long distance would be too hard to focus without "packet loss", and short distance I'd just assume walk up and plug something in if I needed fast communication. That or stick to radio waves which are much more practical.]]></description><dc:creator><![CDATA[Andrew]]></dc:creator><pubDate>Mar 12th 2007 10:22AM</pubDate></item><item><title><![CDATA[Comments on Matsushita demonstrates data beaming with visible light]]></title><link>http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</link><guid isPermaLink="true">http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</guid><description><![CDATA[You're kidding me, right?  You do know that light moves at 186,000 miles per SECOND, right?  That means that no matter how fast you have that light flashing for transferring data, you would have to be "shaking" the device pretty damn fast (faster than the speed of light) for the data to get messed up in the transfer.<br><br>Therefore, your statement is just debunked.]]></description><dc:creator><![CDATA[Kev50027]]></dc:creator><pubDate>Mar 12th 2007 12:38PM</pubDate></item><item><title><![CDATA[Comments on Matsushita demonstrates data beaming with visible light]]></title><link>http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</link><guid isPermaLink="true">http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</guid><description><![CDATA[It doesn't matter how fast you shake it, if you move the light beam out of the line of sight then it's going to lose some of the data, and when you're flashing that quickly you could lose a good chunk of data pretty fast.]]></description><dc:creator><![CDATA[Andrew]]></dc:creator><pubDate>Mar 12th 2007 12:49PM</pubDate></item><item><title><![CDATA[Comments on Matsushita demonstrates data beaming with visible light]]></title><link>http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</link><guid isPermaLink="true">http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</guid><description><![CDATA[Even with loads of shaking, Kev50027 was right. An example of 'operational while shaking wireless' communication is WiFi. And if there is any data loss, the packets are resent and the user hardly realizes. And with such achievable speeds, the only problem occurs when using a live connection such as messenging or video confernecing. Even then, with a light source covering a wide angle of reception/transmission, this thing would be darn hard to slow down or disconnect.]]></description><dc:creator><![CDATA[Generic]]></dc:creator><pubDate>Mar 13th 2007 4:19AM</pubDate></item><item><title><![CDATA[Comments on Matsushita demonstrates data beaming with visible light]]></title><link>http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</link><guid isPermaLink="true">http://www.engadget.com/2007/03/12/matsushita-demonstrates-data-beaming-with-visible-light/</guid><description><![CDATA[You're aware that the very first wireless remotes for television used visible light, are you not?
