ABSTRACT:
A hubodometer (10) for attachment to a vehicle's wheel structure for sensing a rotation of the wheel structure and for converting the sensed rotation to a distance travelled. The hubodometer comprises an outer housing (12) having a permanent magnet (28) affixed thereto for generating a magnetic field and a coupler (14) for coupling the housing to the wheel structure such that the outer housing rotates therewith. The hubodometer further comprises an anti-rotation mechanism (16) rotatably coupled within the outer housing, the mechanism having a plurality of components (18,20,22,24,30) coupled thereto, the components being stabilized against rotation thereby. The components include an electronic controller (20) and a plurality of magnetic field sensors (30). The plurality of sensors are disposed relative to the housing such that as the magnet rotates thereabout all of the plurality of magnetic field sensors do not simultaneously sense the magnetic field. In one embodiment the hubodometer is programmed via the plurality of sensors with calibration related data after the hubodometer is sealed. In another embodiment the display is powered by an output of an illumination-to-current conversion device (40 ), the device output also being coupled to the electronic controller such that illumination modulated in accordance with information is read and interpreted by the controller.
