Patent number: 11981349Abstract: Embodiments of the present disclosure relate to behavior planning for autonomous vehicles. The technology described herein selects a preferred trajectory for an autonomous vehicle based on an evaluation of multiple hypothetical trajectories by different components within a planning system. The various components provide an optimization score for each trajectory according to the priorities of the component and scores from multiple components may form a final optimization score. This scoring system allows the competing priorities (e.g., comfort, minimal travel time, fuel economy) of different components to be considered together. In examples, the trajectory with the best combined score may be selected for implementation. As such, an iterative approach that evaluates various factors may be used to identify an optimal or preferred trajectory for an autonomous vehicle when navigating an environment.Type: GrantFiled: February 18, 2021Date of Patent: May 14, 2024Assignee: NVIDIA CorporationInventors: David Nister, Yizhou Wang, Julia Ng, Rotem Aviv, Seungho Lee, Joshua John Bialkowski, Hon Leung Lee, Hermes Lanker, Raul Correal Tezanos, Zhenyi Zhang, Nikolai Smolyanskiy, Alexey Kamenev, Ollin Boer Bohan, Anton Vorontsov, Miguel Sainz Serra, Birgit Henke

Patent number: 11978065Abstract: Disclosed herein are systems and methods for managing transaction disputes. Techniques include accessing a transaction pattern model associated with a user account; detecting deviation of a transaction from the transaction pattern model; transmitting, based on the detected deviation, transaction data to a user device; receiving an input at the user device in response to the transmitted data; generating, based on the received input, dispute data; storing the dispute data; monitoring data extracts associated with the user account; detecting, based on the monitoring, a data extract indicating a posted state of a transaction associated with the dispute data; and updating the dispute data based on the data extract indicating the posted state.Type: GrantFiled: April 3, 2023Date of Patent: May 7, 2024Assignee: Fidelity Information Services, LLCInventors: Jeffrey Paul Kubler, Shane Saunders, Joseph Fredric Sutthoff, Joe Leung, Lauren Morrison, Matthew Petersen, David Raynault, Philip J.

Publication number: 20240137153Abstract: A device may receive a PDCCH signal, may decode encoded bits of the PDCCH signal to generate coded bits, may reencode the coded bits, and may calculate a detection error probability of each coded bit at an output of soft demodulation. The device may calculate a channel decoding error probability that cyclic redundancy check bits are still attached to the coded bits, and may calculate an error probability of channel reencoding, of each coded bit, due to error propagation of polar decoding and reencoding. The device may calculate a probability density of a BMR associated with the coded bits, and may calculate a threshold based on the detection error probability, the channel decoding error probability, the error probability of channel reencoding, and the probability density of a BMR. The device may determine that the PDCCH signal is invalid based on the BMR being greater than the threshold.Type: ApplicationFiled: October 20, 2022Publication date: April 25, 2024Inventors: Jiancao HOU, Wei LI, Matthew David BROWN, Chi-ming LEUNG

Patent number: 11966228Abstract: In various examples, a current claimed set of points representative of a volume in an environment occupied by a vehicle at a time may be determined. A vehicle-occupied trajectory and at least one object-occupied trajectory may be generated at the time. An intersection between the vehicle-occupied trajectory and an object-occupied trajectory may be determined based at least in part on comparing the vehicle-occupied trajectory to the object-occupied trajectory. Based on the intersection, the vehicle may then execute the first safety procedure or an alternative procedure that, when implemented by the vehicle when the object implements the second safety procedure, is determined to have a lesser likelihood of incurring a collision between the vehicle and the object than the first safety procedure.Type: GrantFiled: December 16, 2022Date of Patent: April 23, 2024Assignee: NVIDIA CorporationInventors: David Nister, Hon-Leung Lee, Julia Ng, Yizhou Wang

Publication number: 20240095661Abstract: A system and method for managing inventory for an electronic raffle is provided. The system may include an inventory database to store inventory data for one or more items to be sold via the electronic raffle, wherein the inventory data includes in-store inventory data and online inventory data, a mobile application configured to generate a raffle entry for the one or more items, a raffle database configured to store the inventory data and one or more raffle entries, and a middleware server configured to update the in-store inventory data stored in the raffle database based on the updated in-store inventory data obtained from the inventory database. The middleware server selects a first round winning raffle entry, transmits a notification to the mobile device associated with the first round winning raffle entry, and initiates a payment process upon determining that the first round winning raffle entry applies to the lightning round.Type: ApplicationFiled: September 15, 2022Publication date: March 21, 2024Applicant: Hibbett Retail, Inc.Inventors: Christopher Lee Blair, Jerrel Devan Cooley, David Alan Stachowiak, JR., Ryan Christian Besterwitch, Kevin Leung Young

Patent number: 11926346Abstract: In various examples, a yield scenario may be identified for a first vehicle. A wait element is received that encodes a first path for the first vehicle to traverse a yield area and a second path for a second vehicle to traverse the yield area. The first path is employed to determine a first trajectory in the yield area for the first vehicle based at least on a first location of the first vehicle at a time and the second path is employed to determine a second trajectory in the yield area for the second vehicle based at least on a second location of the second vehicle at the time. To operate the first vehicle in accordance with a wait state, it may be determined whether there is a conflict between the first trajectory and the second trajectory, where the wait state defines a yielding behavior for the first vehicle.Type: GrantFiled: August 5, 2021Date of Patent: March 12, 2024Assignee: NVIDIA CorporationInventors: Fangkai Yang, David Nister, Yizhou Wang, Rotem Aviv, Julia Ng, Birgit Henke, Hon Leung Lee, Yunfei Shi
