High-Tech Door Better than Star Trek
`The Tanaka Auto Door opens automatically when you stand in front of it. Even better, it only opens just enough to let the individual person come in.
The Auto Door consists of individual slats that slide open and closed from the side of the door. Each slat is half the width of the door; each slat has a sensor. If you stand in front of the door, the sensors determine how much of the door needs to open to allow you to enter. ‘
