    • In order to provide a modular arrangement, an inverter for an electric traction motor used to drive an automotive vehicle is positioned in proximity with the traction motor. The inverter is located within a compartment adjacent to one end of the electric traction motor and is cooled in a closed system by spraying a liquid coolant directly onto the inverter. The liquid coolant absorbs heat from the inverter and is cooled by a heat exchange arrangement comprising a reservoir with pipes carrying a second coolant from the radiator of the automotive vehicle. In a preferred embodiment, the coolant is collected from the inverter in an annular reservoir that is integral with the compartment containing the inverter. In accordance with one embodiment of the cooling arrangement, heat from the inverter vaporizes the liquid coolant by absorbing heat from the inverter during a phase change from a liquid to a vapor. The vaporized coolant is condensed by a circulating second coolant in pipes connected to the vehicle's radiator through a condenser that is preferably coaxial with the motor and the annular reservoir, which annular reservoir in the second embodiment collects overspray liquid coolant. In order to avoid degrading the inverter, the coolant is a dielectric fluid.
    • 为了提供模块化布置,用于驱动机动车辆的电动牵引电动机的逆变器位于牵引电动机附近。 逆变器位于与电力牵引电动机的一端相邻的隔室内,并通过将液体冷却剂直接喷射到逆变器上而在封闭系统中冷却。 液体冷却剂从逆变器吸收热量,并且通过热交换装置来冷却,所述热交换装置包括具有从机动车辆的散热器承载第二冷却剂的管道的储存器。 在优选实施例中,冷却剂从与逆变器的隔室成一整体的环形容器中从逆变器收集。 根据冷却装置的一个实施例,来自逆变器的热量在从液体到蒸汽的相变期间通过吸收来自逆变器的热量来蒸发液体冷却剂。 蒸发的冷却剂通过连接到车辆散热器的管道中的循环第二冷却剂冷凝,该冷凝器优选地与电动机和环形储存器同轴,该第二实施例中的环形储存器收集过喷液体冷却剂。 为了避免降低变频器,冷却剂是介质流体。

    • A method and system for circularly symmetric anisotropic filtering over an extended elliptical or rectangular footprint in single-pass digital image warping are disclosed. The filtering is performed by first finding and adjusting an ellipse that approximates a non-uniform image scaling function in a mapped position of an output pixel in the input image space. A linear transformation from this ellipse to a unit circle in the output image space is determined to calculate input pixel radii inside the footprint and corresponding filter coefficient as a function of the radius. The shape of the footprint is determined as a trade-off between image quality and processing speed. In one implementation, profiles of smoothing and warping components are combined to produce sharper or detail enhanced output image. The method and system of the invention produce natural output image without jagging artifacts, while maintaining or enhancing the sharpness of the input image.
    • 公开了一种用于单通道数字图像翘曲中的扩展椭圆形或矩形覆盖区域上的圆对称各向异性滤波的方法和系统。 通过首先查找和调整在输入图像空间中输出像素的映射位置近似非均匀图像缩放函数的椭圆来执行滤波。 确定从该椭圆到输出图像空间中的单位圆的线性变换,以计算占空比内的输入像素半径和对应的滤波器系数作为半径的函数。 足迹的形状被确定为图像质量和处理速度之间的折衷。 在一个实现中,平滑和翘曲部件的轮廓被组合以产生更清晰或细节增强的输出图像。 本发明的方法和系统在保持或提高输入图像的清晰度的同时产生自然输出图像而不产生锯齿状伪像。
