At one time all the grocery stores all had doors that would open automatically when you stepped upon a black rubber mat that lay about 4-5 feet in front of the door. They worked great. As you walked the doors swung open. there was some kind of trip switch under that black mat.
Today every door at any store is opened by a sensor using X-band radar. When the radar gun senses movement, the door opens. What bugs the bejebbers out of me is, it seems none of those things is aimed right. Perhaps I walk faster than the average bear, but I’m always right on top of the stupid door before it opens. I always have to change my stride or I’ll end up bumping into the door! :mad:
What exactly is the benefit of using this type of system or the black mat method? I would think the old method (which worked better) would be far, far cheaper than a device that has to generate a radar signal. Why did everyone go to this system, and why can’t they make it open the door about 3 seconds sooner?
