Abstract: A method of calibrating a radar sensor includes receiving radar returns from a plurality of objects based on a radar signal sent from the radar sensor, each of the radar returns having a magnitude, at least a subset of the objects are known static objects, identifying a location and orientation of the radar sensor when the signal was sent, identifying expected reflectance values for each of the plurality of known static objects, calculating a conversion function configured to adjust the magnitudes of each of the radar returns for the known static objects to an estimated reflectance value based on the expected reflectance values for each of the known static objects, and adjusting an output of the radar sensor based on the conversion function.

Abstract: A method and apparatus for implementing a method are disclosed. The method includes providing point cloud data to a machine learning algorithm, the point cloud data detected in the vicinity of an autonomous vehicle. The method further includes differentiating, via the machine learning algorithm, in the point cloud, data directly representing a location of a first object and data indirectly representing a location of a second object. The method includes transforming the data indirectly representing the location of the second object into data directly representing the location of the second object and generating corrected point cloud data based on the data directly representing the location of the first object and the data directly representing the location of the second object. The method includes outputting the corrected point cloud data to the autonomous vehicle.

Abstract: The technologies described herein relate to a radar system that is configured to generate point clouds based upon radar tensors generated by the radar system. More specifically, the radar system is configured to generate heatmaps based upon radar tensors, wherein a neural network receives the radar tensors as input and constructs the heatmaps as output. Point clouds are generated based upon the heatmaps. A computing system detects objects in an environment of an autonomous vehicle (AV) based upon the point clouds, and the computing system further causes the AV to perform a driving maneuver based upon the detected objects.

Abstract: Technologies described herein relate to learning parameter values of a preprocessing algorithm that is executed in a radar system. The preprocessing algorithm is configured to receive raw radar data as input and is further configured to generate three-dimensional point clouds as output, where the preprocessing algorithm generates the three-dimensional point clouds based upon the raw radar data and the parameter values that are assigned to the preprocessing algorithm. To learn the parameter values, the preprocessing algorithm is converted to auto-differentiated form and is added as an input network layer to a deep neural network (DNN) that is configured to identify objects represented in three-dimensional point clouds. The parameter values are learned jointly with weight matrices of the DNN.

The computing system employs a hierarchical arrangement of transformers to fuse features of first sensor data output by the first sensor system and second sensor data output by the second sensor system.

More specifically, the radar system is configured to identify bins in radar tensors that correspond to objects in an environment of the radar system, and to use energy values in other bins to construct a point cloud. A computing system detects objects in an environment of the radar system based upon the point clouds.

Abstract: A switch, used as an electronic-memory element, comprising a conductive organic polymer layer sandwiched between, and in contact with, two metallic conductive elements. In an initial post-fabrication state, the organic polymer layer is relatively highly conductive, the post-fabrication constituting a first stable state of the memory element that can serve to represent a binary bit “1 or 0,” depending which of two possible encoding conventions is employed. A relatively high voltage pulse can be passed between the two metal conductive elements, resulting in a market decrease in the current-carrying capacity of the organic polymer layer sandwiched between the two conductive elements. This change in conductivity of the organic polymer layer is generally irreversible, and constitutes a second stable state of the memory element that may be used to encode a binary bit “0” or “1,” again depending on which of two possible encoding conventions are employed.

The array includes a plurality of microlenses, each of which has a minimum planar dimension and a maximum planar dimension. The minimum planar dimensions of the microlenses are larger than the maximum wavelength of visible light emitted from the OLEDs. The maximum planar dimensions of the microlenses are smaller than the smallest minimum planar dimension of any of the OLEDs.
