ABSTRACT:
An electronic cane having a grip and a stick contains, inside of the grip, sensors for sensing physical parameters of the surrounding environment and of the user of the cane. Predetermined maximum and minimum values of the parameters are programmed and an alarm is activated if a parameter is outside of the range. The circuitry for performing these functions is in a retractable case. A panic button is also provided for.
