Homeland Security Commissions LED-Based Puke-Saber
E++99 writes "Homeland Security has contracted with Intelligent Optical Systems, Inc. to develop an "LED Incapacitator," a nonlethal weapon consisting of a large flashlight with a cluster of LEDs capable of emitting "super-bright pulses of light at rapidly changing wavelengths." Sounds innocuous enough... until they they shine "the evil color" at you and you start puking! A working prototype has been completed, and they will soon be putting it through its paces. Homeland Security hopes to give it to Border Patrol agents and National Guardsmen by 2010."
Wow, wait until the bulimics get hold of this on the black market!
...as long as the bad guys aren't allowed to have mirrors.
coding is life
How long till you can get this in a Java applet?
...not that you'd be an effective terrorist with your eyes closed. BTW, is it wrong of me to want to see this used on large crowds?
How will people defend themselves against this?
Use the MAD method: Wear mirror sunglasses.
Does it also work against editors who relentlessly post the same stories over and over again?
Puke, I am your father.
We definitely need some kind of device to shield our eyes from this "light". As I understand a practical way would be just covering our eyes, we could shape them as glasses! Not only that, but it could protect us from the suns blinding rays... I suggest we call this device "sunglasses" to deceive others of its true purpose!
Now if someone just invented these "sunglasses"...
to clean up all the puke at the borders?

While non-lethal technology has the potential to be fantastic, there's a downside to be considered too.
With a gun, there's a certain level of commitment before it's used. An officer of the law must make a determination that he or she is really certain about before shooting, because hitting an innocent person is absolutely unacceptable. As a result, the tendency is to, unless there's no option, NOT shoot someone if you can hold them at bay with the THREAT of shooting. A side effect of this is that an officer given a bad order to shoot is much more likely to abstain, because once he pulls the trigger, it's all over.
As a result, innocent folks are often held at gunpoint until their identity/non-criminalness is confirmed. While traumatic and stressful, this is better than an alternative that's growing increasingly common:
Enter, the taser. Potentially a wonderful tool for stopping an attacker without permanently injuring them, doctrine has instead developed in many police and security departments to 'Zap first, ask questions later'. The 'non-injurious' aspect of the tool means that the bar is that much lower on whether or not to shoot, because "after all, if they're innocent, then it's just a bit of discomfort".
The growing number of non-lethal tools is on the surface a good, even GREAT thing. The real danger though, is a long term one. With the bar set so low, more and more people will be subject to excruciating pain, and eventually, this technology may evolve into a tool of even greater oppression of liberty than anything we have now.
Imagine if a protest can be casually broken up by making everyone vomit or crap themselves uncontrollably. If the government has the ability to casually stop groups of people from coming together or otherwise detaining them while being able to argue "it's not fatal, it's just uncomfortable", then the bar on violating our rights as citizens drops too.
So I'm interested and optimistic about the technologies, but I desperately hope that better effort is invested in making them a net positive for all of humanity and not the boot that might otherwise grind our faces into the dirt.
There has to be a real question here of morality and the rules of engagement for such a device. There seems to be a growing tide of opinion that as long as a weapon is "non-lethal", i.e. it won't kill you or leave behind long-term effects then it is magically fine to use in a very wide range of situations. Real questions have to be asked at some stage as to the *morality* of allowing widespread use of something that makes you sick/shocks you/blinds you purely on the basis that "it has no long term effects and allows us to subdue people" - so does a kick in the face, but I don't see officers doing that (unless they are caught on camera in which case the get suspended then eventually let off).
Coming up next, Slashdot follows the troubling development of a nonlethal technological device for "controlling" troublesome individuals, consisting of two small metal or plastic bracelets joined by a short chain that can be "locked" around the suspect's hands, entirely preventing him from using them until someone "unlocks" the device with a special key.
On whom will this fiendish device be used? Are YRO at risk if this nasty little tool falls into the hands of border guards and police? What if someone immobilized by this device falls and hits his head because he can't break his fall with his hands? Will he sue? Doesn't this violate the Constitution somehow?
Wouldn't it be easier to just have border officials who spoke Spanish?
Sure, you can close your eyes, but you'd better hold your ears too. One of their elite researchers has discovered the brown noise

Would not that be quite dangerous for epileptic ? What about an epileptic, getting a crisis AND omitting at the same time. Guaranteed drowning in one own puke, followed by a civil lawsuit against the government? What about other condition which could threaten life if you start puking (I am not a biologist/doctor so there might be none but I ask) ?

Please, learn to meme properly. Although it is a well-known fact that Rainier Luftwaffe Wolfcastle actually cries "The goggles do nothing" when starring his role as Radioactive Man, the precise Slashdot meme is commonly stated as "The goggles, they do nothing!". Please, report to the men at the door, where you will be asked to hand in your UID, geek card and, should that be the case, mirror goggles.
They're probably referring to pulse repetition rate (1/frequency) when they say "wavelength".
Right after a neuron fires it "rearms" the membrane by pumping ions across it. In time sequence its sensitivity varies smoothly through:
- The absolute refractory period: Nothing can fire it.
- The negative afterpotential: It can be fired but it takes extra stimulus.
- The positive afterpotential: It takes LESS than the usual amount of stimulus to fire it.
Then it returns to its normal, resting, sensitivity.
The sensitivity slope may be an artifact of the ion pumps and channels, but it appears to function as a mechanism for encoding the strength of a stimulus as a pulse rate.
This has a side effect: If a nerve is given short pulses of stimulation with a spacing corresponding to the length of time between a stimulus that fires it and the peak of the positive afterpotential, once it fires once it will tend to continue to fire in synchrony with the pulses from then on. If you have a bundle of such nerves with similar timing and all affected by the stimulus, each additional pulse picks up additional nerves and phase-locks them to the stimulus. Within a few pulses most of the fibers in the bundle tend to be firing rapidly and in unison.
You can see this with a strobe light with a variable repetition rate. Run it slow and you see distinct pulses - a flicker. Run it fast and you see a continuous light - the pulses have fused into a continuous response. But run it near the "flicker fusion rate" boundary and you get a lot of weird visual effects - notably flickering rainbow colors across the neighboring (or entire) visual field that tend to enhance and obscure the actual image with a flickering, undecipherable, psychedelic-poster version of itself.
You get colors other than those of the actual source (if it is colored rather than white) and effects in other parts of the visual field than the actual strobing light and things it is illuminating. This is because nerves for parts of the eye that would not normally be stimulated enough to trigger by this light (if it were non-strobing) still become entrained when they happen to be in a positive afterpotential period when a blink occurs.
(By the way: Don't try this if you're epileptic. It can produce a seizure. Indeed: Some people discover they're epileptic when they are exposed to such flickering lights.)
One speculation about the hypothetical "brown note" was that infrasound at a positive-afterpotential repetition rate matching that of nerves controlling the intestines might force peristalsis in the colon or trigger the appropriate reflexes for defecation. (It might be interesting to retry the debunking experiments with a train of narrow high-pressure pulses, approximating impulses, rather than a sine wave. B-) )
This flashlight appears to be attempting a variation of the same effect. By entraining the nerves of the visual processing responsible for locating onself in space and/or ones motion, it could create a visual illusion of movement that doesn't match the signals from the inner ear and the muscle-position sensors. A mismatch among these three systems produces motion sickness, nausea, and vomiting.
This reflex appears to be a defense against ingestion of neurotoxic poisons (such as those in some mushrooms and food-poisoning bacteria), using their disruption of the complex navigation system as an early warning and attempting to eliminate them from the digestive system before enough are absorbed to disable a critical system and kill the victim.
