  • Publication number: 20250078531
    Abstract: A method includes obtaining, by a processing device, input data derived from a set of sensors of an autonomous vehicle (AV), generating, by the processing device using a set of lane detection classifier heads, at least one heatmap based on a fused bird's eye view (BEV) feature generated from the input data, obtaining, by the processing device, a set of polylines using the at least one heatmap, wherein each polyline of the set of polylines corresponds to a respective track of a first set of tracks for a first frame, and generating, by the processing device, a second set of tracks for a second frame after the first frame by using a statistical filter based on a set of extrapolated tracks for the second frame and a set of track measurements for the second frame, wherein each track measurement of the set of track measurements corresponds to a respective updated polyline obtained for the second frame.

  • Publication number: 20200285607
    Abstract: The present invention provides a fast and efficient way of processing structured data by utilizing an intermediate file to store the structural information. The structured data may be processed into a Binary mask Format (BMF) file which may serve as a starting point for post-processing. A tree structure built on top of the BMF file may be constructed very quickly, and also takes up less space than a DOM tree. Additionally, BMF records may reside entirely in the memory and contain structural information, allowing SAX-like sequential data access.

    Abstract: A multi junction photovoltaic device includes lower pn junction layers comprising silicon and upper pn junction layers formed over the lower pn junction layers. The upper pn junction layers include a CdTe layer, wherein the upper pn junction layers are electrically serially connected to the lower pn junction layers. The upper pn junction layers can convert a first portion of photons into a first electric voltage. The lower pn junction layers can convert a second portion of photons into a second electric voltage lower than the first electric voltage.
