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

Publication number: 20220257396Abstract: Medical device delivery devices, systems, and methods are disclosed herein. According to some embodiments, a medical device delivery system includes a core member and a coupling assembly positioned about the core member. The coupling assembly may include an engagement member having projections configured to engage a medical device and a release member that is movable between a compressed configuration and an expanded configuration. A medical device can extend along the core member such that, when the release member is in the compressed configuration, the projections of the engagement member engage the medical device and when the release member is in the expanded configuration, the release member prevents the projections from engaging the medical device and/or facilitates expansion of the medical device.Type: ApplicationFiled: February 17, 2021Publication date: August 18, 2022Inventors: Mark Ashby, Danyong Zeng, Agee Barooni, Khoa Dang Vu, Ashok Nageswaran

Patent number: 9289215Abstract: This invention is directed to implantable coils and, more particularly, to a coil implant having a stretch-resistant member internal to the coil. The implant of the invention is able to freely articulate and torque prior to delivery. Once delivered, the implant is no longer stretch resistant and is therefore able to substantially conform to the vascular site.Type: GrantFiled: November 27, 2012Date of Patent: March 22, 2016Assignee: Covidien LPInventors: Brian Michael Strauss, Todd Jeffrey Hewitt, Ramon Torres Carillo, Khoa Dang Vu, William Robert Patterson, Stacy Leon Faught, Lawrason Charles Wilbur, Scott William Brennan, Vince Divino

Patent number: 8864790Abstract: An intravascular implant delivery system carries an implant by retaining an engagement member engaging the implant in a position proximal of an aperture at a distal end of the delivery system. The engagement member is retained proximal to the aperture by a cord that obstructs the movement of the engagement member through the aperture. The engagement member is free to rotate and move within an area defined by the delivery system, allowing the implant to react to forces imparted to the implant by the movement of the delivery system and implant through a delivery catheter. Once the implant is in a desired implant position, the cord is moved away from an aperture and the engagement member is allowed to move away from the delivery system.Type: GrantFiled: April 16, 2007Date of Patent: October 21, 2014Assignee: Covidien LPInventors: Brian Michael Strauss, Earl Howard Slee, Ramon Torres Carrillo, Khoa Dang Vu, William Robert Patterson, Jessica Liang, Richard Stephen Bein, Todd Jeffrey Hewitt, Stacy Leon Faught, Vince Divino, Darrell Christopher Drysen, Mark Philip Ashby, Justin Arthur Klotz, Maria De Jesus Sanson, Scott William Brennan, Lawrason Charles Wilbur, Lester Eugene Oestreich

Publication number: 20140238943Abstract: A method for treating a suspension of mineral particles in water, such as mineral tailings, includes the step of contacting the suspension of mineral particles in water with a specific water-soluble polymer. This polymer is preferably a water-soluble polymer having an anionicity of between 10 to 55 mol %, and more preferably 20 to 50 mol %. Furthermore, this polymer has preferably a molecular weight between 15 and 40 million daltons, and more preferably between 18 and 30 million. The method involves adding the specific polymer into a thickener containing the tailings to treat, and/or during transport of the suspension to a deposition area for dewatering and solidification, or to the tailings to treat followed by a mechanical treatment such as centrifugation, screw press and filtration.Type: ApplicationFiled: February 22, 2013Publication date: August 28, 2014Inventors: Cedrick Favero, Scott Ramey, Trong Dang-Vu

Patent number: 8801747Abstract: This invention is directed to an implant having a coil for embolizing a vascular site, such as aneurysm. The coil has a specific three-dimensional shape that is achieved by winding the coil around a mandrel in a specific pattern and then heat setting the coil and the mandrel, another aspect of the invention. The three-dimensional shape resembles unclosed mobius loops. Also provided are methods of making the coil and methods of embolizing vascular site.Type: GrantFiled: February 27, 2008Date of Patent: August 12, 2014Assignee: Covidien LPInventors: Brian Michael Strauss, Todd Jeffrey Hewitt, Ramon Torres Carrillo, Khoa Dang Vu, William Robert Patterson, Lawrason Charles Wilbur, Justin Klotz, Scott William Brennan, Vince Divino
