Patent Images
1. A system for calibrating a mass-flow sensor of a combine, the system comprising:
- a yield monitor associated with the mass flow sensor;
a first wireless transceiver operatively connected to the yield monitor;
a second wireless transceiver on a grain carrier for transmitting calibration information relating to the actual weight to the first wireless transceiver, the second wireless transceiver arranged for transmitting an acknowledgement signal to the first wireless transceiver regarding a distance between the grain carrier and the combine and a heading difference between the grain carrier and the combine, wherein the mass-flow sensor is calibrated for a load of the combine if the distance is less than a maximum desired distance and if the heading difference between the grain carrier and the combine is less than a maximum desired difference.

Abstract
A system and method is provided for remotely and automatically calibrating a mass-flow sensor in a yield monitor of a combine. The invention uses a wireless communication device installed on a combine and a remote wireless communication device installed on a grain carrier or truck carrier. Once an actual weight is obtained, calibration information is sent to the combine to calibrate the mass-flow sensor.
