No. 0007 - Vincinty Velocity Detector
This morning as I was about to walk into my office building, this nice man in front of me held the door open for me. My velocity was just right that he didn't really have to wait for me to come, neither did I have to speed up to catch the door; it was perfect timing. However, as I looked back, this lady was behind me about 10-15 feet away. Here's my dilemma, should I wait or should I go? If I stay, then this lady with 15 briefcases, a carry-on and a lunch sac will feel obligated to speed up to catch the door; if not, then she would have to open the door herself. I'm sure a lot of you have experienced similar situations and that's why a vincinty velocity detector will come in handy. What it does is that it will detect all those that are around right as you are approaching the door and measures the average velocity of those around you versus your own velocity (aka relative velocity). And based upon this data, this device will give you a simple go-no-go instruction right as you arrive at the door way whether you should keep the door open for the one behind you or not. As a result, this device can help us avoid much awkward situations of waiting for people to speed up to catch your courtesy. To finish the story, no I didn't wait for that lady this morning.
