Bless the person who devised remote controlled car keys; its a boon being able to locate your car in a crowded lot, thanks to the unique sound. Wish there was something similar for a cycle lock. Wait, there is! Yes, the Acoustic-optical Lock for cycles is designed on similar lines. This version features a lock system that has a radio transmitter in the key and a matched radio receiver in the lock. Simply press the button and the lock makes a sharp sound and switches on the LED light. You not only locate your bike easily but also have a better way of finding it in low-light situations.
Acoustic-optical Lock is a 2012 Design Talents winner.
