Abstract

An electronic blind guidance cane comprised of a handle, a cane member, an electric eye system, and a cordless earphone. The handle body consists of a hollow enclosure and a cover, the enclosure capable of containing the electric eye sensing system which consists a printed circuit board as well as solid sensing electric eyes, a liquid sensing electric eye, a power switch, a battery, and a vibration inductor wired to it. Given the structure of the present invention, the electric eye system is capable of prompting the output of a warning sound or vibration whenever a solid or a liquid obstruction is encountered within a zone of safety to thereby facilitate the distinguishing of the obstruction.

Claims

1. An electronic blind guidance cane comprised of a handle, a cane member, an electric eye system, and a cordless earphone;

the handle body of the said handle consists of a hollow enclosure having a cover attached to the upper extent and the said cane member is a long rod-like construct having a threaded stud at one extremity for the fastening of the said handle, the features of which are;

The said electric eye sensing system consists of four solid sensing electric eyes, a liquid sensing electric eye, a power switch, a battery, and a vibration inductor wired to a printed circuit board, the said printed circuit board having a signal transceiver, a microprocessor, a voice ic, and a buzzer disposed on it;

when a solid obstruction or a liquid obstruction is encountered within the zone of safety, the said four solid sensing electric eyes facing different directions or the said liquid sensing electric eye senses and transfers to the said signal transceiver, which after the acknowledgement of the said signal transceiver transfers to the said microprocessor such that the said voice ic emits a warning sound via the said buzzer or the said cordless earphone, or the vibration inductor is prompted by the said microprocessor to generate vibration; and

when in close proximity with an obstruction, the outputted warning sound and vibration frequency varies to facilitate the distinguishing of the obstruction.

2. As mentioned in claim 1 of the electronic blind guidance cane of the invention herein, when the user only needs to utilize the said handle of the blind guidance cane, the said handle can be equipped with an attachment member for direct positioning on the wrist to become a portable warning sensor.
