    • A secondary air system providing a regeneration air pump wherein the vanes of the impeller are tapered from a point along the length of the vane to the root of the vane inside the air pump. The tapered vanes create desirable flow characteristics. The tapered vanes create a non-linear flow versus pressure characteristic. Thus, the tapered vanes in combination with a divider that extends circumferentially around the impeller and through the vanes causes the flow to increase. This non-linear characteristic created by the tapered vanes allows the secondary air system to maintain suitable operation at lower flow and pressure levels. Due to the tapered feature on the impeller, a dead head pressure is obtained at a lower pressure. The impeller arrangement also provides overall pump efficiency improvements.
    • 提供再生空气泵的二次空气系统,其中叶轮的叶片从空气泵的叶片长度的一点到叶片的根部成锥形。 锥形叶片产生理想的流动特性。 锥形叶片产生非线性流动与压力特性。 因此,锥形叶片与围绕叶轮周向延伸并通过叶片的分隔器组合导致流动增加。 由锥形叶片产生的这种非线性特性允许二次空气系统在较低的流量和压力水平下保持合适的操作。 由于叶轮上的锥形特征,在较低压力下获得死头压力。 叶轮装置还提供了整体泵效率的改进。

    • A method, apparatus, and system related to field and crop information gathering. In one aspect of the invention, data is obtained from a producer. One example would be yield map data from a yield monitor. Another is “as planted” data from precision farming planting equipment. The data includes information about seed or crop in a producer's field and an identification of the field. The data is combined with other information in a report. The information added could be, for example, soil type information overlaid on the field map. Another example is environmental classification information overlaid on the field map. The report is returned to the producer and used to discuss planning related to the field and the seed or crop.
    • 与现场和作物信息收集相关的方法,装置和系统。 在本发明的一个方面,从生产者获得数据。 一个例子是从收益监视器收取地图数据。 另一个是精确农业种植设备的“种植”数据。 数据包括关于生产者领域中的种子或作物的信息以及该领域的识别。 数据与报告中的其他信息相结合。 添加的信息可以是例如覆盖在场地图上的土壤类型信息。 另一个例子是覆盖在场地图上的环境分类信息。 该报告返回给生产者,并用于讨论与该领域和种子或作物有关的规划。
