I believe that many people have lost an umbrella. But how can we avoid this kind of thing happening again? So I designed this umbrella handle, in which contains a signal termination, it can be installed on different umbrella. When this termination separated beyond the limited distance from the other one installed in your mobile phone, the umbrella will send a signal to your mobile phone, then the alarm will ring out to remind the owner to fetch the umbrella. When you don’t need using your umbrella, you can close the termination in your phone. From now on, you don’t have to worry about losing your umbrella.
