Ultrasonics, The ultimate lock pick?????

[Peaky]

After watching yet another hospital documentry on sky i noticed that the type of ultrasonics that doctors use for pregnant women are being used in a lot more differant uses and it was commented on how cheap they are becoming and how fully portable ones are being used. This got me wondering whether anyone has ever tried using one of these machines to see inside a lock whilst tring to pick it. I dont know whether it will 'see' through the wood or even the steel side of the lock but it seems like a good idea if it means you can see what levers you are lifting and to what height. Maybe somone on here has medical experiance or does/has worked in that envoiroment and can tell what the limitations of these machines are. Obviously low cost to a doctor could mean £80k but it may be worth looking into (not found one on ebay yet ) the newer ones have a pencil type probe and a small potable screen.

all you need is a picture of the lock in your head, as long as you know whats in their and how it works, you can achieve a similar result.
if not carefull you can weigh yourself down with kit that takes 20 mins to set up before you begin picking.

[Peaky]

Very good point, theres also the problem of relying on technolagy that can let you down which leaves you out of practice for doing it the proper way. oh well it was only an idea.

I think higher security safe locks use resin wheels to defend against this type of attack.

I think the problem with this is ultrasonic waves only travel through liquid well. That is why doctors use a gel or pad between the detector and patient. With a cylinder lock it may work because there is solid material, but I doubt it since the whole thing would resonate rather than there being distinct pressure waves. With lever locks it wouldn't work at all since there is a big airgap between the door and the levers. X-rays do work and that is what resin wheels are needed to defend against. Two new technologies out are millimeter wave imaging and X-ray backscatter which might be more promising against resin wheels, but are expensive.

I doubt this would work on steel

Remember Faraday's cage

I doubt it would work on steel too, at least not without significant modification to the hardware. But it's not to do with Faradays cage, that is only for electromagnetic radiation, not sonic.

[oli-the-picka]

In theory a high enough, powerful enough ultrasonic 'frequency' can melt steel, i was thinking of a device which causes more havoc than a standard vibrating pick by reall really giving it a shake! Just a thought

Stick a piezo transducer on the lock, shove in a tension wrench, and tell the customer to stand back.

Way, WAY back. Then, hit the sonics. Use sub-sonic, not ultra sonic. The low frequency will resonate better, and you won't have all the dogs in the neighborhood howling.

If you don't open the lock, you'll probably break a window at the very least.

Good luck.

And you might be able to communicate with a submarine at the same time.

[Romstar]

Are they still using E.L.F. for submarines?

I better get myself a really, really long wire.

I believe the Navy still has the antenna in northern Wisconsin. Not sure if they use it at all anymore. Now they use the E-6 ( Boeing 707 ) for most of the comm. stuff.

When I was at University, one of the lecturers was experimenting with "infra-sound" (ultra low frequency). He set the kit up and one of the cleaners came in hit and tinkered (why??) - apparently they blew out a couple of windows (and their job)

i know they use that method in the SAS , using a sort of mini radar system to locate pins in a lock. i checked the price but the mini radar thingies cost 2000 ponds sterling, about 4000 dollars, see if any of you guys can find it

[toomush2drink]

"mini radar thingy" so how would that work and how do you know they use that ?
