Latest Patents

Seed Meter Monitoring System. This invention monitors whether seeds are present in the cells of a seed meter. A detector sends seed-presence information to a processor, which provides an operator readout to help adjust the meter and maintain the intended seed population. In one embodiment, a video camera captures the cells and the readout presents them in slow motion after the seed singulator. Another embodiment uses a light source and an opposing detector to identify whether a cell contains material.

Electronic Seed Rate System for a Grain Drill. This system uses sensors and an electronic controller to monitor and adjust the seeding rate of a grain drill or similar implement. Fluted feed wheels move with a drive shaft, and an actuator adjusts the shaft in response to the difference between the desired and actual rates. For wider implements with multiple shafts, a switching circuit allows one control circuit to manage individual sections and operate the relevant actuator.

Career Highlights

Coordes’s patents address practical challenges in precision agriculture: confirming seed presence and maintaining a target seeding rate. Together, the inventions describe monitoring and control technologies intended to help operators manage seed delivery through agricultural implements.

Collaborations

Coordes is associated with Deere & Company. His named coworkers include Richard Wayne Hook and Paul Reed Riewerts.

Conclusion

Duane Allen Coordes’s patent work centers on improving the accuracy and control of agricultural seeding through seed-meter monitoring and electronic rate adjustment.
