Unlock Your Doors With a Knock Code

Erica Campbell writes to tell us IsraCast is reporting that E-lock has developed a new kind of lock technology designed to open a door based on a "knock code." From the article: "This innovation is based on patented technology which uses a series of quick knocking sounds. The discrete mechanical knocks open the lock and are produced by a small device that can be carried by any authorized person. The device which opens the lock needs to touch the door (which can be made out of any material such as metal, wood, plastic or glass) to cause the lock mechanism to open. Since there is no keyhole or contact point on the door, this unique mechanism offers a significantly higher level of security then existing technology."

Door bell

[SpaghettiPattern]

My brother in law once made a door bell which opened the door if the right ringing combination was givven in a specific rithm. Worked great but had a minor flaw that if the bell rang 30 seconds the door would open anyway. That wasn't a problem as nobody would have tried. The neighbors started hating him when he started using the flaw as a feature when he came home too drunk to be rithmical.
