Publication number: 20240144489Abstract: A method for multi-object tracking from video. The method includes the following steps: (1) Capturing frames from the streaming source and preprocess the data; (2) Extract video features with three choices: a 3D-CNN backbone followed by a Transformer Encoder, a Video Transformer Encoder, a 2D-CNN Encoder with a stack of frames as input followed by a Transformer Encoder; (3) Multi-object tracking using a new end-to-end multi-task deep learning model named JDAT (Joint Detection Association Transformer), then post-processing and updating tracking state with Temporal Aggregation Module (TAM). The deep learning models in step 2 and step 3 are trained simultaneously end-to-end with a loss function that is accumulated over multiple timesteps (Collective Average Loss—CAL). Also, the model can be pretrained with weakly labeled image dataset in a self-supervised learning manner first, then finetuned on supervised video datasets with full tracking labels.Type: ApplicationFiled: October 3, 2023Publication date: May 2, 2024Applicant: VIETTEL GROUPInventors: Hong Dang Nguyen, Thi Hanh Vu, Manh Quy Nguyen

Patent number: 11356409Abstract: Disclosed are various embodiments for managing network address allocations using prefix allocation trees. In one embodiment, a request is received to allocate a network address block. The request specifying a prefix size for the network address block. A particular network address block having the prefix size that is allocatable is determined based at least in part on a prefix allocation tree representing the available and allocated network address space. The prefix allocation tree is updated to indicate that the particular network address block is allocated. An identification of the particular network address block is returned in response to the request to allocate the network address block.Type: GrantFiled: March 29, 2021Date of Patent: June 7, 2022Assignee: Amazon Technologies, Inc.Inventors: Benjamin Kaiwen Ng, Jason Goelitz, Eric Andrew Rubin-Smith, Lee Alan Wildes, Adam Gregory Cogen, Nam Quy Nguyen

Patent number: 11118422Abstract: Systems and methods for monitoring system health of a well cementing operation are disclosed. A well cementing system includes several fluid pathways and holding/mixing containers. A series of sensors monitors the status of the fluid pathways and the holding/mixing containers. There are redundancies in the fluid pathways, and a preferred order in which the fluid pathways are used. Under normal conditions the fluid for the cementing operation is moved from place to place via the most desired pathway. If the sensors detect a fault, the next-most desired fluid pathway is used. If there are no available fluid pathways, an alarm is issued.Type: GrantFiled: August 28, 2019Date of Patent: September 14, 2021Assignee: Schlumberger Technology CorporationInventors: Dinh Quy Nguyen, Carlos Urdaneta, Gang Qu, Rajnarayanan Balsamy

Publication number: 20110024199Abstract: An elastomeric seal ring is located between each bearing pin and each cone of an earth-boring bit. An auxiliary ring or band is imbedded within an annular recess formed in the inner diameter of the seal ring. A portion of the inner diameter of the seal ring as well as the auxiliary ring are in dynamic contact with the bearing pin. The auxiliary ring has a geometric feature that enhances radial flexibility but prevents it from sealing. The geometric feature may be a transverse cut, notches in either the inner or outer diameters, or holes extending between the sides of the auxiliary ring. The auxiliary ring has lubricating properties.Type: ApplicationFiled: August 3, 2009Publication date: February 3, 2011Applicant: Baker Hughes IncorporatedInventors: Anton Zahradnik, Gregory L.
