Lamperd, a "firearm training system" company, has patented a bracelet that delivers debilitating shocks when remotely triggered. Their killer app for this is aviation safety: they're proposing that the TSA could force everyone who flies to wear one of these and then flight-attendants could zap us into a stupor if we turn out to be Al Quaeda.
A method of providing air travel security for passengers traveling via an aircraft comprises situating a remotely activatable electric shock device on each of the passengers in position to deliver a disabling electrical shock when activated; and arming the electric shock devices for subsequent selective activation by a selectively operable remote control disposed within the aircraft. The remotely activatable electric shock devices each have activation circuitry responsive to the activating signal transmitted from the selectively operable remote control means. The activated electric shock device is operable to deliver the disabling electrical shock to that passenger.




I DONT THINK SO!!!!!!!!!!!!! I will drive.OR, if I have to, I will get a row boat before I allow some one to shock me!

Another reason not to fly. It is already a truly miserable experience, which for me ruins the idea of going on any holiday.

So what would they do for passengers who are epileptic, have pace-makers or??
I do not fly anyway.
I have always preferred to drive.

its another gimmick to make us feel protected from terrorist.that electrical charge could detonate an explosive device instead of preventing from going off.

lol This one made me laugh. Why would any serious company that actually put hundreds of thousands and perhaps millions of dollars into developing this device come up with such a bizarre application. Wouldn't it have been logical to claim an applicable use for such a device in, say, the penitentiary system? Transporting dangerous criminals?
But, no! Some brainiac in the company had a brain fart and said that there were more non-criminals than criminals, and it would be more profitable to hook us all up. Smart! That guy is getting his paycheck.

P.S. The electrical charge is unlikely to detonate any modern explosive. Most need a detonator, and it is more than a little thing that goes 'bang'. A lot of explosives you can hit with a hammer, drop from a plane, light on fire, and would still not give you a bang.

I am sure it will be used there as well soon.

Most of those explosives are the ones that need a high voltage shock to set off (which is what the bracelet does). Just because it doesn't react to mechanical means doesn't mean it will not react to high voltage electricity.

thats what i thought.watching "braniacs, science abuse" on tv the use everything from plastic explosives to thermite all use an electrical stimulus to activate the detonator.they blow up loads of caravans.great stuff!!

I've given this some thought, and I think they're going about this the wrong way. Instead of negative reinforcement (e.g. PAIN bracelets ... you see where this is headed?) how about POSITIVE reinforcement: e.g. PLEASURE bracelets. Everybody gets a bracelet that wires to the pleasure centers, and as soon as they sit in their assigned seat, it goes to work. I mean, think about it: people would fly MORE often, they would enjoy it more, and NOBODY would want to hijack the plane.

Terrorist: must ... blow up .... plane .... OHHHHHHH, just a few more minutes.

Hillarious. The airlines would be flooded with lawsuits. As we see by example any such tech would be abused. Somebody gets drunk offends a stewerdess. Payback is the push of a button. Naomi Campbell better learn to control her temper while flying. Ooops Im sorry, the button got stuck. Have a jolt with that drink sir? LOL

OK. Do many people here actually know what "high voltage" means?

Yes, have degree. Have degrees in several disciplines. Do you have a specific question? Is your question rhetorical?

I believe it means that each unit of charge that flows has a larger amount of energy than if the voltage was low.

Voltage is the electromotive force (EMF) pushing the current flow. Current is a measure of electron flow rate given in avegodros number (6.23 x 10 to 24th power) of electrons.

E(voltage) x I(current flow) = Watts(power) :: E(voltage) = I(current) x R(resistance)

Resistance is the resistance a medium(conductor or insulator) has to current flow.

It takes about 70 volts of EMF to overcome dry skin resistance and induce a small current flow.

Stun devices induce a high voltage usually 7,000 to 15,000 of very short duration to swamp nerve paths and induce strong muscular contraction causing pain and loss of muscle control. The voltage drops to zero almost instantaniously because a taser device is incapable of delivering enough power to cause much current flow.

Nerves work by electric current induced along the nerve by nerons firing across gap to adjacent nerve cell.

Get up against a high voltage power line of 10,000 volts where the supply is capable delivering enough power to mantain a high current flow (voltage does not drop due to current drain) and you will look a lot like fried chicken as a result.

One tenth of an amp of current flow through the heart muscle is enough to cause muscular contraction inturrupting blood flow. A healthy heart will resume beating after current is removed but a heart patient could be in real trouble. Also a severe shock patient (current delivered for too long a time) might not recover.

Shock devices are DC current causing a sudden clamping of muscle as well. AC current due to current reversing direction cause heart to fibrillate (pulse or vibrate). Defibrilation is induceing a DC clamping effect to stop a fibrillating heart and hopefully allow it to resume normal beating.

This is the foundation of pacemaker and emergency shock devices.

Does that help?

I do not quite see what Avogadro's number has to do with it.

one amp is one avegadros number of electrons flowing past a point.

Test.

Yep

this is a test please ignore.

Anyway, I had a long-winded explanation typed out as to why the definition of the amp is not related to Avogadro's number, but the board won't let me post it. The only thing in common between Avogadro's number and the number of electrons in making up one coulomb (an amp is one coulomb per second) is a leading digit of six and that they are both of high orders of magnitude (but actually differ by five orders of magnitude).
