ABSTRACT:
This specification discloses a mile post location system particularly useful with a vehicle having a citizens band radio. The system includes a keyboard having switches which are representative of numbered digits, such that the vehicle operator may input an initial mile post designation indicative of the present location of the vehicle. The keyboard further includes switches to enable the vehicle operator to input incrementing or decrementing instructions. A computer circuit is responsive to the operation of the keyboard switches in order to store the initial mile post designation and the incrementing or decrementing instructions. A transducer is responsive to the distance traveled by the vehicle in order to generate and apply signals to the computer circuit. In response thereto, the computer circuit causes the initial mile post designation to be incremented or decremented in accordance with the stored instructions. A display is responsive to the computer circuit for displaying to the vehicle operator the last mile post passed by the vehicle in order to enable the vehicle operator to broadcast his present location on the citizens band radio.
