The handicapped find many difficulties that complicate their life and prevent them from living a normal social life. In order to ease their embarrassment and improve in some way the quality of their life, the "laser stick with rechargeable battery" has been created. It consists of a special stick for blinds inside which an electronic device is inserted. This device is formed by: a rechargeable battery, an integrated circuit producing a little laser ray, and a tiny computer that analyses and sends to a buzzer the encoded signal. In practice, as the laser ray approaches the objects, it indicates to the tiny computer their distance; consequently, the computer emits a sound of different frequency that the blind will learn to identify in a while. The more the obstacle is next, the more the sound is sharp and vice versa. In order to prevent the stick from becoming an annoyance in the long run, a switch for turning on and off the device at pleasure, has been inserted on its handle, so that the blind will be free to use it whenever he/she needs (e.g. in unknown places) and deactivate it in places he/she well knows. An aspect not to be overlooked is the psychological effect of the "independence" deriving from the constant use of this futuristic device. The inventor is asking, if possible and considering the humanitarian importance of this accessory, for the collaboration of public corporations, as well as individuals, to the development of this extraordinary device.
