Abstract: A spray nozzle system includes a housing having an upper cap, a neck portion for helping to support the housing adjacent a component, and at least one fluid flow line for supplying a fluid to an interior area of the housing. A plurality of spray nozzles may be included which are housed in the housing and in communication with the at least one fluid line for distributing the fluid over a circumferential surface of the component.

Abstract: A system and method for selectively reducing or filtering data provided by one or more vehicle mounted sensors before using that data to detect, track and/or estimate a stationary object located along the side of a road, such as a guardrail or barrier. According to one example, the method reduces the amount of data by consolidating, classifying and pre-sorting data points from several forward looking radar sensors before using those data points to determine if a stationary roadside object is present. If the method determines that a stationary roadside object is present, then the reduced or filtered data points can be applied to a data fitting algorithm in order to estimate the size, shape and/or other parameters of the object. In one example, the output of the present method is provided to automated or autonomous driving systems.

Abstract translation: 一种用于在使用该数据检测，跟踪和/或估计位于诸如护栏或障碍物之类的道路侧面的静止物体之前，选择性地减少或过滤由一个或多个车载传感器提供的数据的系统和方法。 根据一个示例，该方法通过在使用这些数据点来确定是否存在固定的路边对象之前对来自多个前瞻性雷达传感器的数据点进行合并，分类和预排​​序来减少数据量。 如果该方法确定存在固定的路边对象，则减少或过滤的数据点可以应用于数据拟合算法，以估计对象的大小，形状和/或其他参数。 在一个示例中，本方法的输出被提供给自动或自主驾驶系统。
