From the page:
"Research and development on the concept of Intelligent Speed Adaptation is going on both regarding speed limits and dynamically changing limits due to the prevailing conditions (e.g. adverse road-, or weather conditions).
The system investigated is based on the Active accelerator pedal. "
The active accelerator pedal makes it possible to go over the speed limit, but you have to press harder on it, so that you dont speed by mistake. AFAIK the trials are a sucess, the problem is the cost of the equipment, and the cost to keep the devices updated with the correct speed limits.

OK, understood.
The link that the parent submitted does not support teh notion that the shuttle was designed for horisontal takeoff. I have commented on this, and given support by links, in my other reply.
It would be helpful if you could cite the chapter, because I can not find any statement about that the horisontal takeoff concept existed after 1970 in the development of the shuttle...
(In hindsight it is always easy to see how an accident could have been avoided. The trick is to in advance make sure that every accident is avoided...)
Do you have any references for this? The space shuttle has been a vertical take of vehicle since 1970: http://www.astronautix.com/lvs/shuttle.htm
I guess that you talk about the early configuration shown in the first picture on http://www.abo.fi/~mlindroo/SpaceLVs/Slides/sld029.htm
But that configuration was also meant for a vertical takeoff, as can be seen in the third picture. The wings on the booster part is only for the return flight.
Stormtroopers supposed to be clones? I do not think that there is any reference to that in EP4-6, so in "classic" SW the answer is no. In "modern" SW, EP1-6, I do care what the answer is. I do not really care for what they have done to the mythology in Ep1-3, and I choose the regard them as "revisionist" tales, marginally interesting but not any source for the "truth" of that mythic universe.
My snake-oil detecters did light up at the following sentence from in-three's webpage:
"Dimensionalized(TM) 3D content looks extremely realistic, typically better than if it had been originally photographed in 3D."
Artificial things that are claimed to be better than the real thing often are not anywhere near that. And also the repeated statement that "there is no eye fatigue, none whatsoever". It contradicts my understanding of the medical background for the eye fatigue, which is due to that stereoscopic pictures only accounts for one of (at least) half a dozen of optical phenomena and vision processes that accounts for depth perception. (I think it is very interesting that in-three's website does not have a single picture showing any demo of their technology.)
I suppose you are joking, but in case you are not: A car seat will not hold for the impact of the backseat passenger! As a matter of fact, the hinges will probably not hold for the seat itself. I have once been first at the scene of a car-crash: single person in the car, both seats folded completely forward.
Your computer will become an excellent projectile in the case of an emergency stop, hard landing, crash etc. And I do not want to have your laptop impacting my neck... (The same reason I prefer that people sitting behind me in a car are using the seat belts: I do not want to be crushed between them and my seatbelt.)
I am not aware of any block used with the japanese swords that uses the guard as a stop. It is far to unreliable for that.
Regarding european style medieval fencing, John Clemens writes in "Medivel Swordmanship" that "...the function of the wide medieval cross-guards seems ot have been for preventing the user's hand from slamming into or hitting against the flat of an opponents shield". And as the Jedi knights do not use shields, there is no real use for a guard.
This does not only apply to CG special effects, but also to the very popular "flying-in-wires", popularised by the chinese action movies. It makes me cringe every time. A love a good swordfight, but most of the chinese ones are unwatchable due to their wierd physics. And then we shold not begin speking of the latest Hollywood action movies...
Globalstar is not global, and misses Africa, but Iridium seems to be global, at least according to their site. And Inmarsat is global, except at the polar regions.
The exceptions for Iridium seems to be: "The four Restricted Countries where the Iridium phone will not complete a call to the local phone system are: N. Korea, Poland, & Hungary. " (yes, there is only three, but see for yourselves at wwwg.lobalcomsatphone.com)
But at least the "Sauce" ramge of things do exactly that: pure ramping of the different PWM-controlled LEDs. The spectrum that the toys go through is not percieved as a constant hue-speed change, but it changes abruptly sometimes. I was very disappointed with this...
The Lemelson-MIT award does not have a very good track record, at least not from my POW. One example is the text on their web-page about Wilson Greatbatch, another lifetime award winner, which is seriously lacking in accuracy. (It talks about designing the first sucessful pacemaker implant, which is true only if "sucessful" is taken as "working for more than 9 months." If the time limit is set to anything less, the inventor is suddenly swedish...)
You are exactly right when talking about colors or the "feel" of a lighting design.
But when talking about color temperature, and the article states that "adopt a cooler temperature for white", we talk about a temperature in Kelvin, where 0 is commonly regarded as very cold, and a temperature in the tousands as considerable hotter.
The article states that: "The way to think about it is that on a chart of all possible colors, the 6500K color temperature is actually a line of white whereas D65 is a specific point of white."
This is definitly false. In all the color charts that I have seen, the range of possible black-body colors is a line, but at black-body radiator at a certain temperature is as much a point as the D65 standard. The difference is that the D65 illuminant includes an UV component, which will change the way printed colors appear to the human eye. I fail to see that the article makes a good case for using the D65 illuminant as the reference standard.
Furthermore, a cooler temperature will appear redder, not bluer. And the colors percieved is ass much due to our brain as to the spectrum hitting our eyes. So which color temperature that is the correct one for monitors depends on where the monitor will be used, especially on the color temperature of the room lighting.
We have no instruments that observe earths rotation around the sun directly. We have a lot of instruments that give data that strenghtens the theory that earth is rotating around the sun. And we have a theory of why that could be the case.
That is what natural science is about: to find theories and models that describe the world around us. Never do we talk about any theory being proven to be true: truth is a matter for the philosophers and the religions.
This is not correct. Increasing the power increases the SNR, and increases the maximimum possible bandwidth.
Exhibit 1: Shannons law Exhibit 2: Various coding schemes actually make use of the reflections, which therefore is not a problem anymore. One extreme version of this is MIMO systems.
Yes, Tolkien changed a (small) part of Bilbo. But there are some critical differences between this change and the revisions being made by Lucas. Tolkien only changed it once. The first version of Bibo was printed in 1937, the second in 1951. The LoTR was printed in 1954, after the revision of Bilbo. And there, when the groundwork of the sequel was laid, Tolkien stopped.
Another small detail is that in the frame of how "the Red Book", of which the book "the Hobbit" is supposed to be a part, is presented in the trilogi: It is the story as told and written by Bilbo Baggins (and others), it is not inconcievable that he would write two separate versions, one where he looked nice and one more true. Which still fits within the framework of the world designed by Tolkien. The difference here with Star Wars is that films typically present an "objective" point of view into another reality, and thus presents what "actually" happend, and not what someone remembers. Which makes it more disturbing when they changes.
I do not have the choice: The "original" version is not marketed by anyone right now. I have to try to find it second-hand. Which is not the same thing.
And the fundamental difference is that films of LoTR is, by necessity, an intrepretation of an already existing piece of fiction. But the first Star Wars defined the story. Then any alterations to that story becomes an alteration the the viewers concept of the "star wars"-reality. And such alterations strains the suspension of disbelief.
I am sorry, but I do not find the two cases even remotly similar.
But the (big!) difference is that in the case of LoTR, you have a choice: both versions are or will be available. With Star Wars you have no choice: only the "revised" version is available. (In shops. Now. In a current format. etc.)
Actually, the use of 802.11 is heavily regulated. It is license-free, but that is another thing. It only means that you dont need a separate license for each device that you operate. But the devices still has to comply with regulations on frequency use, power levels and spurious emissions. And not all use of 802.11 is without problems, especially when operated close to other networks, like Bluetooth, and devices using the same frequency allocation, such as microwave ovens.
It is always dangerous to mix the wave and the particle view of EM-theory at the same time. One effect that you will get with the proposed scheme is that as you adjust the power of the laser in time (which gives you the possibility to modulate the laser with the function G(t)), you will widen the spectra of the green photons. No, I can not explain this in any clear way from the viewpoint of the particle intrepertation, but it is very obvious from the wave intrepretation. It is this widening of the spectra that gives the occupied bandwidth, and it is this bandwidth that is used in the Shannon formula. So when you add the modulation to the green laser it will widen its spectra. Probably not into the red are (it depends on the speed of the modulation), so you could still use the red laser for another transmission. But this is the same thing as having different channels in FM-radio, for example.
There is one big difference between EM-signals and soundwaves though: polarisation. But that is another story. I hope this helps? Otherwise I will try again.
And also here the AC comment in the granparent is correct. And your initial post in no way shows where you think he is incorrect. Maybe you should read some litterature on the technology, and not only press releases?
I know how phased arrays work. I teach about them. We build them. We have them in the lab. And your desctriptin would not pass an exam at ours. My (too short ) definition would be: the summation, with variable phase and amplitude, of the signals from two or more different antennas in order to synthesize a new antenna pattern.
Phased arrays are not fundamnetally different from other directional antennas, such as parabolic dishes. And I will uphold that position until you show me how they are different.
From your previous post: you are correct that one positive side of the phased arrays are that they are stationary, you dont have to move them mechanically. They are also often more compact, and you have the possibility to synthesize multiple beams. But the same thing can be achived by one or multiple high-gain antennas.
