this is a great idea, and there is somewhere someone who is probably working on the mechanics of this idea. I envision pullys, hidden wires, tension measuring devices, abdominal and intestinal function sensors, and microwave rechargable, heavy duty batteries. I think I have actually acquired a pair of these pants! I didn't get a chance to charge the batteries on the pants before if went out for the evening, so it was quite a surprise when I found another way to actuate the waist tightening properties of the pants. It was in the lowly Macdonalds 1/4 pounder with cheeze. after a month of these babies, my pants tightened so much, I had to get new ones!! I will not tell anybody about this fact though, because I think you deserve a chance to work on your invention without interference from me. Good luck
