Oh man, I've never been so excited about a product in my life. D Free: a wearable something that notifies you ten minutes before you have to take a crap. The website is here:

"Maintain human dignity" indeed.

I think it's still in development but I'm absolutely getting one when it comes out. Price is no object.

Aside from the very sparse website, the only information I see is of the "look how wacky Japan is" news items. But I'd love to see if this works.
