This new automatic door from Japan creates a minimal opening for an object to pass through. The door is composed of a series of strips which open when activated by the infrared sensors on their edges. It’s said that the door also can identify people (RFID?) for security. Such doors can help manage energy loss in a a room, garage or freezer and protect a space from unwanted dust, pollen, bugs, and germs. Plus, they are cooler than the doors on Star Trek.

Here’s a marketing tip: get the door to occasionally say “Gee, you’ve lost weight, haven’t you?” and it will sell like hotcakes.
