Publication number: 20230351795Abstract: In various examples, sensor data—such as masked sensor data—may be used as input to a machine learning model to determine a confidence for object to person associations. The masked sensor data may focus the machine learning model on particular regions of the image that correspond to persons, objects, or some combination thereof. In some embodiments, coordinates corresponding to persons, objects, or combinations thereof, in addition to area ratios between various regions of the image corresponding to the persons, objects, or combinations thereof, may be used to further aid the machine learning model in focusing on important regions of the image for determining the object to person associations.Type: ApplicationFiled: July 5, 2023Publication date: November 2, 2023Inventors: Parthasarathy Sriram, Fnu Ratnesh Kumar, Anil Ubale, Farzin Aghdasi, Yan Zhai, Subhashree Radhakrishnan

Publication number: 20230328001Abstract: A method of path MTU determination in Generic Routing Encapsulation (GRE) tunnel is presented. A source network device (ND) transmits, to a destination ND that is a second endpoint of the GRE tunnel, a first outer packet including a first inner packet, where the first inner packet includes a first inner header that is used to deliver the first inner packet to the source network device, a first inner GRE header, and a first payload. The source ND receives the first inner packet. The source ND transmits a second outer packet including a second inner packet that includes a second payload that has a size greater than a size of the first payload.

Patent number: 11677675Abstract: Path MTU determination in Generic Routing Encapsulation (GRE) tunnel is presented. A source network device transmits, to a destination network device that is a second endpoint of the GRE tunnel, multiple GRE encapsulated packets that include multiple inner packets respectively, where each inner packet has an inner header used to deliver that inner packet to the source network device and a different payload, and where each of these GRE encapsulated packets has a different size. The source network device receives a first portion of the inner packets from the destination network device and does not receive a second portion of the inner packets. The source network device determines a path MTU to the destination network device based on the size of the GRE encapsulated packet with a largest size for which a corresponding inner packet is received at the source network device from the destination network device.Type: GrantFiled: October 25, 2021Date of Patent: June 13, 2023Assignee: CLOUDFLARE, INC.Inventors: Nicholas Alexander Wondra, Erich Alfred Heine, Yan Zhai

Patent number: 10783382Abstract: A method of performing lane detection without the use of a frame buffer may include capturing image frames with an image sensor in a vehicular imaging system. Feature extraction circuitry in the vehicular imaging system may analyze a frame to detect features corresponding to possible lane markers. The features may be extracted and stored in memory for further processing, while the rest of the frame may not be stored in memory and may not undergo further processing. Processing circuitry may perform a first estimation of lane marker location based on a continuous feature that is present in multiple different image frames and may perform a second estimation of lane marker location based on multiple features in a single image frame that form a connected feature. The processing circuitry may determine the presence of a lane marker based on the continuous feature and the connected feature.Type: GrantFiled: April 6, 2016Date of Patent: September 22, 2020Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventor: Yan Zhai
