    • An angular velocity control for a boom of a machine is disclosed and a method for controlling the angular velocity of a boom of a machine. The angular velocity control includes a calculator that detects input signals from an operator control lever, a boom angle sensor, a cylinder length sensor, a chassis cant sensor, and a chassis tilt sensor. Movement of the operator control lever allows an operator to pre-select a desired angular velocity. Based on the geometry of the boom to the machine the calculator calculates a boom gain associated with the current boom angle. The calculator then calculates a necessary cylinder velocity to achieve the desired angular velocity. The calculator sends a control signal to an electrohydraulic control module which in turn sends a signal to an electrohydraulic valve associated with a boom lift cylinder. The electrohydraulic valve alters the flow rate of hydraulic fluid into or out of the boom lift cylinder to produce a cylinder velocity that in turn produces the desired angular velocity of the boom.
    • 公开了一种用于机器的起重臂的角速度控制,以及用于控制机器的起重臂的角速度的方法。 角速度控制包括计算器,其检测来自操作员控制杆的输入信号,起重臂角度传感器,气缸长度传感器,底盘倾斜传感器和底盘倾斜传感器。 操作者控制杆的移动允许操作者预先选择所需的角速度。 根据起重臂到机器的几何形状,计算器计算与当前起重臂角度相关的起重臂增益。 然后,计算器计算必要的气缸速度以获得所需的角速度。 计算器将控制信号发送到电动液压控制模块,该电液控制模块又将信号发送到与动臂提升缸相连的电动液压阀。 电液阀改变液压流体进入或离开起重臂提升缸的流量,以产生气缸速度,该气缸速度又产生起重臂所需的角速度。

    • An integral connector for a piezoelectric solid state motor stack having a plurality of ceramic disks interleaved with electrodes. Lead wires connect the electrodes to a source of electrical potential. A housing, for containing the motor stack, includes a connector body mounted to one end portion of the housing. A plurality of contact pins mounted to the connector body are adapted to be connected to the source of electrical potential. A structure defines a path for guiding the lead wires between the contact pins and the electrodes, wherein the lead wires exit the combination of the ceramic disks and electrodes along first and second parallel longitudinal axes separated by a first distance, and attach to the pins which are located along third and forth parallel longitudinal axes separated by a second distance, wherein the first distance is different from the second distance.

    • In one embodiment of the present invention, a method for transitioning a mobile machine from a first path to a second path within a work area includes selecting from among one or more transition schemes, wherein the transitions schemes are composed of one or more interim paths between the first path and the second path. The desired transition scheme is chosen by evaluating one or more performance criteria including whether the interim paths overshoot the second path and whether the interim paths remain within a perimeter surrounding the work area. Additional performance criteria that may be evaluated include the number of interim paths the mobile machine must follow to transition from the end of the first path to the beginning of the second path, the number of heading changes required by the candidate transition scheme, and the amount of the first path and the second path that is traversed by the mobile machine as a result of the candidate transition scheme. A validity grade is determined based on the performance criteria, and the transition scheme having the optimum validity grade is selected. Determining the validity grade may also include using weighting factors on the performance criteria.
    • 在本发明的一个实施例中,一种用于将移动机器从工作区域内的第一路径转换到第二路径的方法包括从一个或多个转换方案中进行选择,其中转换方案由一个或多个中间路径组成, 第一条路径和第二条路径。 通过评估一个或多个性能标准来选择所需的转移方案,包括中间路径是否超过第二路径以及临时路径是否保持在工作区周围的周边内。 可以评估的额外的性能标准包括移动机器必须遵循的从第一路径的结束到第二条路径的开始的过渡路径的数量,候选过渡方案所需的标题变化的数量以及数量 由候选转移方案的结果由移动机器遍历的第一路径和第二路径。 根据性能标准确定有效等级,并选择具有最佳有效等级的转换方案。 确定有效性等级还可以包括对性能标准使用加权因子。

    • Most existing noise reduction enclosures used with engines and engine driven equipment have failed to meet the reduced noise emission requirements of today and of the future. A few of the present enclosures meet the reduced noise emission requirements of today and of the future but are extremely expensive to purchase and are large bulky structures. The subject enclosure (10) is reasonably priced and provides an enclosure which is effective in reducing the noise emitted therefrom. The enclosure (10) includes a housing (32) having a generally rectangular configuration and being divided into an engine portion (56) defining an engine compartment (57) and a duct portion (54). The outlet ducts (88) having a length greater than the inlet ducts (84). To further enhance the noise reduction of the enclosure (10) a plurality of dynastic hardware is attached to the housing (32).
