| New technologies for scoring systems
The FIE has an aversion for any radiated wireless signalling system, fearful of external tampering (which is highly improbable, although technically possible).
Instead, we might consider making the available target the signalling system. At the Summer Nationals, Leon Paul demonstrated the new material, D30 (or something name that) which is normally pliable when slowly manipulated, but hardens under high accelerating stress. If the material can notice a difference, then it becomes a signalling device: high stress is a hit, low stress is nothing.
While the material might be extremely expensive to make into a jacket or mask or whatever, the philosophy is that it's possible to make the detection on the target end rather than the source end (the weapon end, that is).
Now today, I read about quantum dots that create light when electricity is applied to it. Read here about the quantum dots.
So, we imbue the jacket or lame or mask with quantum dots. Apply electricity with the weapon, either by electrostatic discharge similar to the current StM wireless saber system, or by a wired system and voila, light will go on. Don't know how exactly to get the foil system down.
One note, for Mr. Roch, there's no way to prevent flicks. The only way I can see to prevent flicks from ever happening is to stiffen the blade so much that it's humanly impossible to do so. Of course, you're then liable for the increased number of deaths and serious injury that such a route might take.

| The technology is very fascinating, although without wireless communication between the suits, lockout timings are hard to handle in anything besides sabre. There are electronic ways to make a wireless fencing setup that plugs into a normal scoring machine and make it virtually impervious to anyone 'hijacking' the signal, but I think SEMI or whatever commitee it is that makes these descisions isn't run by technical experts. 
Oh, wait, it just may be possible. Hmmm.

| foil blades of like, say, FIE stiffness (bf white) would be too stiff to do major flicks with.

| I use bf white and flick all the time. Even now.

| I use my super stiff BF epee blade to flick all the time. It's not difficult.
If the blade is somewhat flexible, and you put a weight (the electric point) on the end, you can flick.

well of course you can flick, but no more of that crazy flick stuff.

| You could prevent flicks by considering them a preparation.  | |

| We don't need wireless. We need a scoring box that can be programmed with differenct tone frequencies. How many times have you stopped because you heard another box go off? (Yeah, yeah, I know - go until you hear "halt" but not every non-competition training bout I'm involved in has a director.) How many times have you called "halt" as a director because you heard another box go off? (Yep, you need to verify the light, but sometimes....)
Seems a trivial change. | |
