A readout circuit for an array of substrate-isolated microbolometer detectors includes a bias source that varies in accordance with changes in substrate temperature as detected by a temperature sensor that has temperature characteristic that resembles the temperature characteristic of the microbolometer detector array so as compensate detector measurements for temperature induced errors in the microbolometer focal plane array read out.

An extendible axle member (146 or 148) is provided for a pivoting axle of an agricultural harvester (100), the extendible axle member (146 or 148) having an elongate telescopic portion (400) with bearing surfaces for being slidably received in an outer axle member (142 or 144), wherein the elongate telescopic portion (400) is formed integral with and abuts a C-frame for supporting a steering knuckle (158 or 160).

An agricultural combine has a flexible unloading tube for discharging the contents of a grain tank positioned on the combine. The unloading tube includes first and second tubes connected by a pair of swivel joints on an intermediate tube. The swivel joints are actuated independent of one another by either electrical or hydraulic power to provide a range of motion significantly greater than found in current combines. A series of augers, connected through flexible joints, move grain material through the unloading tube. The double swivel joints enable the unloader to be conveniently located in the combine with a minimum intrusion on the overall volume of the unit.

Methods and systems for correcting fixed pattern noise (FPN) in infrared (IR) imaging cameras. The methods and systems include correcting IR sensor data different strength levels of FPN data and selecting the particular strength level that produces corrected data with the least amount of FPN. The correction may occur over several frames of IR sensor data in order to find an optimal strength level for correction.

A draper header has a transverse main frame supporting center, left side and right side belt conveyors and including a plurality of transversely spaced knife support members that extend forwardly beneath the belt conveyors from right and left lower rear main frame members and have forward ends on which a transversely extending knife is supported. Each belt conveyor includes a frame disposed within an endless belt and having a rear side hinged to a respective lower rear main frame member for pivoting upwardly between operating and belt-changing positions. Brackets are removably fixed across the length of the knife and have rear edges extending above front edges of the belts when the conveyors are in their operating positions. At least one height adjuster is mounted between the main frame and each conveyor frame for moving each conveyor to its belt-changing position once the associated brackets are removed from the knife.

A grain tank on a crop harvester includes a belted conveyor floor for moving grain in the grain tank toward an opening through which the grain tank is emptied. A sensor determines when the grain has depleted the tank to a substantially low level and activates the floor to remove the remainder of the grain material. A flexible strip between the active floor and the sidewalls of the grain container ensure that grain loss is minimized, if not eliminated. The active floor may be provided in an belt in which the driven side has a lower friction material so as to improve belt life.

An unloader for an agricultural harvester includes a telescopic belted conveyor that can be extended to opposite sides of the harvester. The conveyor can be operated at any selected elevation between a minimum elevation and a maximum elevation and at any extended length between a minimum extended length and a maximum extended length for the conveyor.
