Wind aeolipile
A high-efficiency, hybrid fluid aeolipile is placed in the stream of a moving fluid, preferably air. Energy is extracted from the fluid stream by directing a portion of the stream through and, optionally, around the device. As the fluid flow moves through the device, it is directed into nozzles. These nozzles, which are free to pivot in a cyclical manner, employ the established phenomenon of “nozzle effect” to accelerate the velocity of the air-flow passing through them, which is ultimately ejected from each nozzle tip, producing thrust. This thrust, amplified by nozzle effect, drives the nozzles to pivot around a shared axis. The wind energy, thereby converted into cyclical motion, that may be used to perform useful work, is converted with greater efficiency than is possible in conventional blade-type wind turbines. |

Kurtosis based pruning for sensor-fusion systems
This document describes Kurtosis based pruning for sensor-fusion systems. Kurtosis based pruning minimizes a total quantity of comparisons performed when fusing together large sets of data. Multiple candidate radar tracks may possibly align with one of multiple candidate visual tracks. For each candidate vision track, a weight or other evidence of matching is assigned to each candidate radar track. An inverse of matching errors between each candidate vision and each candidate radar track contributes to this evidence, which may be normalized to produce, for each candidate vision track, a distribution associated with all candidate radar tracks. A Kurtosis or shape of this distribution is calculated. Based on the Kurtosis values, some candidate radar tracks are selected for matching and other remaining candidate radar tracks are pruned. The Kurtosis aids in determining how many candidates to retain and how many to prune. In this way, Kurtosis based pruning can prevent combinatorial explosions due to large-scale matching. |

Glass laminate with inlay obscuration having superior strength and optical quality
The use of camera-based safety systems is growing at a rapid rate in modern automobiles. At the same time, windshields, where many of the cameras are mounted, are becoming larger and more complex in shape. As the industry moves towards vehicles with full autonomous capability, the number of cameras required and the resolution of the cameras are both increasing. However, the optical quality of the windshield is less than optimal. One of the problems is caused by the typical black enamel frit that is printed on the glass, prior to heating and bending, to hide or obscure the camera hardware. The abrupt thermal gradients during bending, caused by the heat absorbing black frit, result in a high level of distortion in the camera field of view. The object of this invention is to provide laminated automotive glazing having an obscuration area produced by creating an obscuration after heating and bending the glass by removing a portion of the plastic interlayer glass in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) and replacing it with an inlay made of a substantially opaque plastic or other suitable material in or near the camera field of view (camera obscuration) or/and in the edges of the windshield (black band) rather than printing and firing an enamel frit on the glass. This results in a laminate having superior optical quality, higher strength and a lower probability of breakage as compared to a laminate with a black enamel frit obscuration. |
