Essentially, Quantum Cryptography works because of Heisenberg's Uncertainty Principle and a thought experiment known as Schrodinger's cat. Basically, when one of these devices transmits a bit, it does so as a single photon with a known "spin." By observing that photon, you modify the very physical properties of that photon and corrupt the data. The man in the middle has no way to reconstruct the data because he has no way of knowing the given properties of a photon in the seqence. Further, that serves to DOS the connection (becuase the man in the middle cannot retransmit the same quantum sequence), thus causing the units to switch off and declare an alarm.
It's similar to Schrodinger's cat: Schrodinger comprised a thought experiement where a cat was put into a sealed box with a poison and a radioactive atom. In the course of 1 hour, the atom has a 50/50 chance of decaying, thus killing the cat. At the end of the hour, the cat is neither dead or alive, but in a state of flux. It's not until you observe the system that you fix the state of the cat as being dead or alive.
Better: modify the parking meters to use the same RFID sensors as the toll roads...one transponder, one account. Here in Orlando, you'll soon be able to use your E-Pass (toll tag) to pay for parking at the Orlando Int'l Airport.
That's not quite true. Some fluorescent bulbs do indeed flicker at 60 or 120Hz--these use the old magnetic ballasts. However, most newer fluorescent (and also HID) lamps use electronic ballasts that are very similar to switching power supplies--they "flicker" at 20,000Hz.
You will have plenty of trouble using VPN if you're behind NAT on a router without passthrough anyway.
No, not really. The new NAT+T incarnation of L2TP with IPSec works quite nicely even in situations where PPTP doesn't work because the router/firewall won't do passthrough...

As long as it follows the advice given to WWII RAF pilots, there'll be no problem: "When a prang seems inevitable, endeavor to strike the softest, cheapest object in the vicinity as slowly and gently as possible."
Guess they didn't look at the OOCEA's [Orlando-Orange County Expressway Authority--a private corporation, actually] deployment: EPass saves them money (so much so that they offer a percentage discount for frequent EPass users--personally, I pay about 130 tolls a month, so the 10% discount is quite nice).
Of course, those highway-speed/open-road tolling lanes are quite nice, too. (Yes, that's right, EPass users can proceed through the plaza at 70mph...and the system even gets the right axle count:-)
Actually, the PC that key is on would have to have an Internet connection. Otherwise, it has no way of accessing the VeriSign TimeStamp server (timestamp.verisign.com), which verifies the date and time of signing (and prevents the signature from expiring when the certificate does).
Yeah, I mean you could buy a Christie Roadie S12 (12,000 ANSI lumens, 1.9kW, 400:1 contrast ratio, 3-chip DMD, 1280x1024 resolution, up to 40' diagonal screen) for only $76,000. Of course, at 1.9kW, we lose the "power saving" aspects of LCD displays...
As the history books record, they were both dismissed as nutcases; when they did the first NMR scan of a brain, they were told that they had fabricated it. It's like Fred Smith of FedEx--his graduate paper on a hub-based air transportation system for packages was given a "C" by his professor (as good as an "F"), yet his idea "took off" (and in a very real way) just a few short years later.
I've run a little over 20,000 pages on my CLJ4550 this year...the split on that is about 60%/40% color/grayscale...so, yeah, my "HP Professional Inkjet" was killing me in terms of consumables.
For me personally, operating costs are more significant than print speed or even print quality.
That's why I've always used laser printers whenever possible [ok, not always, before lasers were around I used dot matrices]. My big points on a printer are operating costs, speed, and utter dependability. My dear mother had a cow when I told her I spent ~$1500 on a Color LaserJet 4550 ("you spent fifteen hundred on a WHAT?")...but, after realizing how much cheaper it was, she apologized for her fit of rage...
Yes, both Fullcircle Talkback and Corel's CARM (Corel Application Recovery Manager) were around before this patent application was filed...and they probably are both instances of prior art...
Now that will never happen. The USPS gets too much money from bulk mailing for them to even consider that...you think $0.37 for a first-class letter is high? It may be much worse...
Of course you'd need one HELL of a DMD projector to make this work
Why? If you remember back to when HDTV was cutting edge and CRT's didn't get that high-res, the FCC demo'd the technology with a light-valve projector called the Eidophor 52HD (Greek for "light bearer") from Gretag which was capable of displaying the HD signal. Now, I know light-valve projectors are all but dead due to LCD and DMD/DLP units, but I wonder if they could resurrect the technology for these very-high-res units. In theory, a light-valve projector (being essentially an analog device) has no real qualms with whatever resolution you want--give it an analog signal, and it'll draw it!
Damn, that's impressive. The GE90-115B (exclusive to the Boeing 777) is currently the world's most powerful turbofan engine and is capable of producing "only" 127,000 lbf (which shattered aviation records the world over for turbofan engines). When you consider that the GE90 is 11.25 ft in diameter (without cowling) and 23.9 ft long (again, without cowling) and NASA's/Boeing's aerospike engine is measured in inches, that's like...damn.
Actually, it doesn't really hurt the sound/video/light/CGI/FX/whatever crews [i.e. the celeried/salaried workers]--they get paid regardless...it's the people who's pay is a percentage that see less money. And why not? If they were stupid enough to go for a job offer with a percent sign...well, you know.;-)

I live in Orange County Florida (hi neighbor to the north!), and we use the same system here: the Optech III-PE (a.k.a. "Eagle") mark-sense tabulator by ES&S (formerly Business Records Corporation).
You can now rent/buy these units. Aquatique Show among others makes them. I was a video tech at a show where they used these--it was 32 feet wide and rear projected with a Christie Digital Roadie X10 (10,000 ANSI lumen digital projector--Eidophor lovers, eat your heart out!) The staging guys installed the screen and catch box in about 4 hours--even on an electrically live stage (i.e. one with 120/208 going though it), there isn't really any concern of water--the catch boxes are very well designed to almost elminiate splashout.
Don't forget that the facsimile was an Italian invention installed first in France--ever heard of the pantelegraph? Not to mention that the first real "fax" machine was invented by the Japanese who couldn't use teletypes to send messages in Japanese.
EZ-Pass or no, it can already be done with AVI (automatic vehicle identification). A system automatically grabs a photo of your license plate at every toll plaza...
Here in Orlando, we have a system called E-Pass, and OOCEA can and will send you a "you've been speeding in the E-Pass lanes again" letter, followed by a ticket since you're supposed to go through those lanes at only 35MPH.
When I first saw this article, I thought "E-Pass" was in reference our very own Orlando-Orange County Expressway Authority electronic toll payment system (nothing like going through a tollbooth at 35MPH knowing you're not going to get a ticket for it).
Wait, doesn't this mean E-Pass could sue OOCEA for trademark dilution?

MRI (or NMR) isn't popular because it's expensive. MRI/NMR is expensive because it isn't popular. 'Nuff said.
