No problem! I hope people realize that transferring an H-1B is actually not that complicated. It sure made me feel a lot more confident about switching jobs.
Always wanted to see something like this! Hope it'll get referenced a lot on resources like Mathworld or Wikipedia. Love the extensiveness!
Dumb question maybe, but is knowledge like this often used in symbolic solver software? If so, would it be useful to implement examples in a programming language like Gerald Sussman did in Structure and Interpretation of Classical Mechanics?
Hi, that's indeed our old sensor which is composed of two AIR sensors. The new sensor carries a slight upgrade in hardware, but the real power comes from our signal processing. See my reply to thwest here. https://news.ycombinator.com/item?id=9879671
We made our own AIR door counter, composed of a few distance sensors. It can tell us in which direction a person is passing, and gives a distance profile that we process to distinguish individual people. Technically, we measure your circumference to some degree, but you might agree that is far from enough to compromise your anonimity.
