  • Patent number: 9696723
    Abstract: A method for autonomously aligning a tow hitch ball on a towing vehicle and a trailer drawbar on a trailer through a human-machine interface (HMI) assisted visual servoing process. The method includes providing rearview images from a rearview camera. The method includes touching the tow ball on a display to register a location of the tow ball in the image and touching the drawbar on the display to register a location of a target where the tow ball will be properly aligned with the drawbar. The method provides a template pattern around the target on the image and autonomously moves the vehicle so that the tow ball moves towards the target. The method predicts a new location of the target as the vehicle moves and identifies the target in new images as the vehicle moves by comparing the previous template pattern with an image patch around the predicted location.

  • Patent number: 9698431
    Abstract: Resinous fibers of nanometer to micrometer width dimensions are drawn from a multi-component system by a melt extrusion process. The process includes a step of combining a fiber resin with a water-soluble carrier resin to form a resinous mixture. The resinous mixture is extruded to form an extruded resinous mixture, the extruded resinous mixture having strands of the fiber resin with the carrier resin. The extruded resinous mixture is then contacted with water to separate the strands of the fiber resin from the carrier resin. An electrically conductive fibrous sheet is then formed from the strands of fiber resin. The fibrous sheets are useful as diffusion layers in fuel cells.

  • Patent number: 9689734
    Abstract: A fluid containment system includes a container, a sensor, and a splash shield. The container has a bottom and defines an interior configured for holding a volume of fluid. The volume of fluid is variable between a low volume range and a filled range. The sensor is operatively disposed in the interior of the container in spaced relationship to the bottom. The sensor is configured to be at least partially submerged in the fluid only when the volume is in the filled volume range. The splash shield is operatively disposed within the interior of the container at a barrier level defined between the sensor and the bottom. As such, the splash shield is disposed between the sensor and a surface level of the fluid when a level of the fluid is less than the barrier level to provide a barrier to prevent fluid from splashing onto the sensor.
