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.
Claims5
An electronic cane including a stick comprising:
- grip means connected to said stick for sensing and processing information including,
- sensor means for sensing information related to physical parameters of the surrounding environment and of a user of the cane;
- microprocessor means, responsive to the information sensed by said sensor means, for processing said information sensed by said sensor means;
- display means for displaying said processsed information;
- key input means, operatively connected to said microprocessor means, for inputting data related to maximum and minimum values of said physical parameters to said microprocessor means;
- said microprocessor means including means for comparing said sensed information from said sensor means with said maximum and minimum values and for generating alarm signal, and
- alarm means, operatively connected to said means for comparing for receiving said alarm signal and for indicating that a sensed physical parameter is outside the range defined by said maximum and minimum values in response thereto.
