摘要:
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.

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.

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.
摘要:
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.

摘要:
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.

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.
