  • Patent number: 12014380
    Abstract: Examples provide customized authorization of item self-returns. A customized returns manager component calculates a customized return-trust score and a per-item return value based on analysis of item data and transaction history data. If a per-user return-trust score is within an unacceptable threshold range or an item value is within an unacceptable threshold value range, a second user is assigned to assist a first user with completion of the proposed return of the selected item. If the per-user return-trust score and the item value is within an acceptable threshold range, a return authorization component authorizes unassisted self-return of the selected item. An item disposition component determines in real-time whether to permit the first user to keep the selected item or instruct the first user to return the selected item to a designated item return area prior to completion of the item return based on a set of item disposition criteria.

  • Publication number: 20240118410
    Abstract: Curvelet-based low level fusion of camera and RADAR sensor information is disclosed and includes processing RADAR data corresponding to a scene to generate a RADAR point cloud and processing camera image data corresponding to the scene using a curvelet transform to identify a target of interest in the scene and generate for the target of interest a target type, (x,y) coordinate values, and a curvelet magnitude per decomposition level. If discrepancies exist between (x,y) coordinate values of the RADAR point cloud and the target type, (x,y) coordinate values, and curvelet magnitude per composition level of the target of interest, a portion of the RADAR data processing is repeated to regenerate the RADAR point cloud; otherwise, the RADAR point cloud to a perception stack of a vehicle.

  • Publication number: 20240054777
    Abstract: The present technology determines noise in an image of a representation of an environment around an autonomous vehicle (AV). A sensor system receives a first image that represents an environment around the AV including at least one object that may be obscured by environmental conditions. The first image is analyzed to determine if pixels in the first image represent noise from the environmental conditions in comparison to other pixels in the first image that represents a higher degree of image detail. A second image can be generated using the pixels in the first image that represent the higher degree of image detail to result in an output that is less affected by noise from environmental conditions and may result in better performance by downstream systems relying of date from the sensor system.

  • Publication number: 20240004056
    Abstract: High-resolution point cloud formation based on the use of a point spread function kernel is disclosed. The proposed disclosure provides the means to generate high angular resolution point clouds by performing a matching process of the point spread function (PSF) to a series of adaptive hypotheses to accurately identify the target signatures using the maximum amount of available information. The proposed method comprises a two-stage processing chain. In the first step, the spatial and the Doppler spectrum of the target responses is calculated and decomposed in terms of the sensor point spread function (PSF). In the second step, the target PSF representation is then processed using a support vector machine to determine the presence of closely located targets that would not be possible to detect using typical automotive RADAR signal processing chains.

  • Publication number: 20240004027
    Abstract: Adaptive differential quantization for ranging sensors and sensor data encoding is enclosed. The proposed disclosure comprises a differential quantization algorithm that extracts the raw signal data gradients to maximize the amount of effective information (using information theory approaches) transferred to a sensor processing data unit. This approach results in an efficient use of the data links between the sensor suite and a central sensor processing data engine, which can allow the use of cost-effective physical links. The proposed disclosure takes advantage of the gradual environment changes observed in typical vehicular platform trajectories.

  • Publication number: 20230399009
    Abstract: Methods and apparatus disclosed within provide a solution to problems associated with the use of either high frequency or low frequency radar signals. Methods of the present disclosure may transmit high frequency radar signals, transmit low frequency radar signals, receive reflected radar signals, and process the received radar signals using parameters respectively suited for processing high frequency and low frequency radar signals. Evaluations may be performed that allow an apparatus to adapt for limitations associated with the processing of high frequency radar data, the processing of low frequency radar data, or both. Different correlation functions may be performed that allow the apparatus to identify objects and to identify object velocities using different sets of program code instructions. These different evaluations and correlations may result in the generation of a set of “point-cloud” information that may be used by other processes of a sensing apparatus.

  • Publication number: 20230393257
    Abstract: Processing of a fractalet radio detection and ranging (RADAR) signal is described. A reference fractalet waveform is received. The fractalet waveform includes self-similar waveforms having lower frequency bands and frequency bands. A reflected fractalet waveform received via one or more antennae is decoded. A waveform profile of chirplet transforms of signals in the lower frequency bands within the reflected fractalet waveform are compared to the reference fractalet waveform. Time spans corresponding to the subset of lower frequency bands are determined. Signals from the higher frequency bands are extracted from the reflected fractalet waveform. Chirplet transforms for the extracted signals from the higher frequency bands are determined for the determined time spans. Spatial frequency components along azimuth direction and elevation directions are calculated for targets based on the chirplet transforms for the extracted signals from the higher frequency bands.
