Abstract
An electronic hub odometer employs a permanent magnet and a magnetic reed switch for recording the number of revolutions of a vehicle wheel to which the odometer is mounted. A programmable integrated circuit electrically communicates with a clock crystal and the magnetic reed switch to automatically produce data relative to the time, distance and rate of travel of the associated vehicle. The data is stored in a random access memory integrated circuit. An infrared light emitting diode is employed for transmitting the data from the odometer to a remote unit. Information is also transmitted to the odometer from a remote unit via a photo-optical detector.
