Ok...ok...for those that have issue with the name....it is now being called the "Canine calmer", "Portable Bark Killer", "the Hush Puppy", "Portable Sound Blaster", and "Electronic High Power Dog Whistle".
If you have not followed Steve Gibson (Shields UP!, SpinRite, etc) and Leo Laporte and their Security Now! podcasts you might be missing something...

He has several forums where he is developing ideas:

He will be giving away (I'm sure they are gone by now...) 20 free kits so that folks can build it and then post video of the working results...
Here is a link to some pics and info on the new prototype:
