gears

What do you mean by module of the gear?

“Module” is the unit of size that indicates how big or small a gear is. It is the ratio of the reference diameter of the gear divided by the number of teeth.
Module =Reference diameter/Number of teeth

Reference diameter = Module × Number of teeth
Reference pitch = π × Module

what is the reference pitch?
It is equal to the circumference divided by
the number of teeth.

Then, what is the reference circle?
Assume that there are two friction pulleys in contact whose diameters are equal to the reference diameters. As the surfaces are smooth, the rotation will not go properly when great force is applied. This problem will be solved if there are teeth on the periphery of the friction pulley. And this is the concept of gearing.

Design Criteria:Fully self contained sensor system for range finding. Interface must be able to support many generic processor families. (8051,6811,68332,ColdFire,TMS320) All data processing to be done real time by sensor. (IE. No after thought software processing required)

Power consumption concerns:  (Battery operation) Physical Size (less than 1.5″ square for final implementation)

Safety:  (Choices of laser equipment must be completely safe for the range to include accidental exposure or even prolonged exposure.
