An apparatus and method for counting wheel revolutions are provided that include
a wheel-hub mountable odometer comprising an accelerometer comprising sensor means
for sensing force, wherein the sensor means are operable to sense a force acting
thereon and generate an electrical signal representative of said force. Further
an electronic control system is provided comprising a microcontroller and power
source, the microcontroller comprising electronic filtering means for attenuating
irregularities in the signal from the sensor means and computing a wheel revolution
count based on said attenuated signal, and output means for communicating the wheel
revolution count. The accelerometer preferably comprises a dual axis electronic
accelerometer with no internally rotating parts. Further, the output means preferably
comprises at least one of a display means, an IR communication system, or a RF
communications system.
