Abstract: An active infrared sensor may include an imaging infrared sensor to provide an output signal conveying time-sequential infrared images of a scene which includes a subject, a beam generator to generate a millimeter wave energy beam, and a processor. An initial infrared image of the scene may be stored in a memory. After storing the initial infrared image, the beam generator may illuminate the subject with the millimeter wave energy beam. A temperature change across the subject due to the millimeter wave energy beam may be estimated based on the output signal and the stored initial infrared image. The beam generator may stop illuminating the subject when a highest temperature change across the subject is at least equal to a predetermined temperature change limit.

Abstract: The cob cleaning conveyor system provides a capability for positively removing or cleaning lighter crop residue from a flow of cobs. The system can be incorporated with a cob collection device, such as on a trailer, and can be adjustable in several ways for accommodating varying corn varieties, conditions and the like. The system includes a first conveyor which propels the flow into a gap or passage toward a second conveyor, while a flow of air is directed downwardly through the passage to remove or clean the lighter residue material from the cobs. The angle of attack of the air flow can be selectable, and optionally be directed downwardly along the second conveyor to the passage, and upwardly along the second conveyor to travel with or follow the residue flow, to suit present conditions.
