摘要： An electro-optic fluid level sensor includes a body having a first end portion and an oppositely disposed second end portion. A light source is disposed at the first end portion of the body. A first light detector is disposed at the second end portion of the body. A second light detector is disposed at the second end portion of the body. The second light detector is axially offset from the first light detector.

摘要： A wind turbine and housing combination may include a horizontal axis radial wind turbine and a housing surrounding the turbine, the housing being incorporated with a cupola or gable roof of a building. The turbine may include an axle, a plurality of blade sections extending radially from the axle, and a generator operatively coupled to a first end of the axle. Each blade section may include a curved drag surface that provides a stall surface normal to the direction of an anticipated wind flow. The generator may be adapted to produce electricity when the axle is rotated. The housing may include a plurality of louvers and a motor operatively coupled to the plurality of louvers. Each louver may be capable of having (i) a closed position that prevents wind from entering the housing and (ii) an open position that permits wind to enter the housing. The housing may be adapted to be attached to an apex of a gable roof of a building.
摘要翻译： 风力涡轮机和壳体组合可以包括水平轴径向风力涡轮机和围绕涡轮机的壳体，壳体与建筑物的圆顶或山形屋顶结合。 涡轮可以包括轴，从轴径向延伸的多个叶片部分和可操作地联接到该轴的第一端的发生器。 每个叶片部分可以包括弯曲的拖曳表面，其提供与预期风流的方向垂直的失速表面。 发电机可以适于在轴旋转时产生电力。 壳体可以包括多个百叶窗和可操作地联接到多个百叶窗的马达。 每个百叶窗可以具有（i）防止风进入壳体的关闭位置和（ii）允许风进入壳体的打开位置。 壳体可以适于附接到建筑物的山墙屋顶的顶点。
