  • Publication number: 20210041574
    Abstract: A method is disclosed for suppressing sidelobes due to artifacts introduced by FFT operations during automotive radar signal processing. Sidelobes of a stronger target from the FFT operations may bury the response from a weaker target when there are multiple targets. The method estimates the sidelobes of an identified target from a measured FFT response and subtracts the estimated sidelobes from the measured FFT response. The identified target may be the strongest target from the measured FFT response. The method estimates the sidelobes to suppress the sidelobes with respect to the peak signal of the identified target. After the estimated sidelobes of the identified target are removed, the updated FFT response may reveal other targets that had been buried. The method may identify additional targets to estimate their sidelobes and may iteratively remove the estimated sidelobes of additional targets from the FFT until a desired sidelobe residual level is achieved.

  • Publication number: 20210041557
    Abstract: A method is disclosed for designing a sparse array for an automotive radar. The method moves each of a number of antenna elements to candidate neighboring grid positions starting from an initial random seed placement to iteratively search for a placement of antenna elements that improves upon a cost function. The cost function for each candidate placement may be determined from characteristics of the FFT response associated with the candidate placement. The method may search for a candidate placement with the lowest cost function among the multiple candidate placements based on the random seed placement. The search may be repeated for a large number of random seed placements to find the candidate placement with the lowest cost function corresponding to each random seed placement. The method may compare the lowest cost functions corresponding to the multiple random seed placements to determine an optimized placement having the minimum cost function.

  • Publication number: 20210019386
    Abstract: This disclosure relates to identification preprocessing. In one aspect, a method includes receiving at an identification server, and from a mobile computing device that has entered a predetermined area surrounding a biometric feature collection device, a group identifier of a user group to which a user of the mobile computing device belongs. The group identifier is transmitted by the mobile computing device in response to the mobile computing device receiving a radio signal broadcast to the predetermined area. The user group is one of multiple user groups. Based on the group identifier, the identification server selects, from a stored registration biometric feature set, a registration biometric feature associated with each user in the user group. The identification server adds the registration biometric feature to a screening feature set established for the biometric feature collection device. Biometric feature-based identification is performed on the user using the screening feature set.

The computer-implemented method includes: extracting text content from user information which corresponds to a user, and using the text content extracted from the user information to generate feature vectors. The feature vectors are further used to form one or more clusters of existing user editions. For each of the one or more formed clusters, a tree structure is generated for each user edition in the cluster. Moreover, the tree structures in the cluster are combined into a merged tree structure. A customized template is generated for each of the one or more formed clusters using the respective merged tree structure, and at least one of the customized templates is recommended to the user based on the user information.

  • Publication number: 20210011592
    Abstract: A computer-implemented method, system and computer program product for generating a user interface. A sketch (e.g., wireframe) of a portion of a user interface is received. The sketch is analyzed to predict a set of intended sketches using artificial intelligence based on historical data and/or the user's asset library. A set of intended final sketch renderings of the user interface is then generated and displayed using the set of predicted intended sketches based on historical data or a model trained to extract visual characteristics from existing user interface screens. If the user selects one of the intended final sketch renderings of the user interface as being directed to the intended design of the user interface and indicates that the selected intended final sketch rendering of the user interface corresponds to the final intended design, then code is generated to render the selected final sketch rendering of the user interface.
