Abstract

A walker and/or wheelchair distance measuring device comprising a wheel assembly, a measuring assembly and a display. The wheel assembly is capable of attachment to a walker, and includes a support and a wheel. The measuring assembly comprises a sensor having a trigger associated with one of the support and the wheel and a pickup associated with the other of the support and the wheel. The processor is electronically coupled with the sensor. The processor is capable of interpreting the information received from the sensor. The display is associated with the processor for displaying results computed from the processor.

Claims

1. A walker and/or wheelchair distance measuring device comprising:

a wheel assembly configured for attachment to a walker or a wheelchair, the wheel assembly having a support and a wheel;

a measuring assembly comprising;

a sensor having a plurality of trigger members associated the wheel and a pickup associated with the support, the plurality of trigger members being spaced apart from each other, and each trigger member having a distinctive signal;

a processor electronically coupled with the sensor, the processor configured for interpreting the information received from the sensor; and

a display associated with the processor for displaying results computed from the processor.

2. The distance measuring device of claim 1 wherein the display is configured for displaying at least one of distance traveled, speed, total distance traveled, average speed.

3. The distance measuring device of claim 1 wherein the display comprises a LCD display.

4. The distance measuring device of claim 1 further comprising memory associated with the processor, the memory configured for storing data pertaining to the movement of the walker.

5. The distance measuring device of claim 4 further comprising an output associatable with an outside device which is configured for retrieving data stored in the memory.

6. A walker and/or wheelchair distance measuring device comprising:

a wheel assembly configured for attachment to a walker or a wheelchair, the wheel assembly having a support and a wheel;

a measuring assembly comprising;

a sensor having a plurality of trigger members associated the wheel and a pickup associated with the support, the plurality of trigger members being spaced apart from each other along the wheel;

a processor electronically coupled with the sensor, the processor configured for interpreting the information received from the sensor; and

means associated with one of the sensor and the processor for discerning between a rocking movement and a walking movement; and

a display associated with the processor for displaying results computed from the processor.

7. The distance measuring device of claim 6 wherein the discerning means comprises a distinction between the first trigger and the second trigger.
