Patent number: 11970161Abstract: A motion planner of an autonomous vehicle's computer system uses reconfigurable collision detection architecture hardware to perform a collision assessment on a planning graph for the vehicle prior to execution of a motion plan. For edges on the planning graph, which represent transitions in states of the vehicle, the system sets a probability of collision with a dynamic object in the environment based at least in part on the collision assessment. Depending on whether the goal of the vehicle is to avoid or collide with a particular dynamic object in the environment, the system then performs an optimization to identify a path in the resulting planning graph with either a relatively high or relatively low potential of a collision with the particular dynamic object. The system then causes the actuator system of the vehicle to implement a motion plan with the applicable identified path based at least in part on the optimization.Type: GrantFiled: February 28, 2022Date of Patent: April 30, 2024Assignees: DUKE UNIVERSITY, BROWN UNIVERSITYInventors: Daniel Sorin, William Floyd-Jones, Sean Murray, George Konidaris, William Walker

Patent number: 10195613Abstract: An apparatus for disintegration (or mixing) of a solid in a receptacle containing liquid, has a control unit and an ultrasound transducer generating ultrasonic energy under control of the control unit. An annular coupling element in communication with the ultrasound transducer is adapted to receive the receptacle. Ultrasonic energy is transferred to the receptacle contents through the annular coupling element. In use, the ultrasonic energy transferred to the receptacle contents causes disintegration of the solid into the liquid. A method for disintegration of a solid in a receptacle is also described.Type: GrantFiled: October 4, 2013Date of Patent: February 5, 2019Assignee: Liquitab Systems LimitedInventors: Tony Spirovski, Neil George Walker, Julian Meyer, David John Bull

Publication number: 20170089814Abstract: The present invention recognizes that diagnosis and prognosis of many conditions can depend on the enrichment of rare cells, especially tumor cells, from a complex fluid sample such as a blood sample. In particular, the present invention is directed to methods and compositions for detecting a non-hematopoietic cell, e.g., a non-hematopoietic tumor cell, in a blood sample via, inter alia, removing red blood cells (RBCs) from a blood sample using a non-centrifugation procedure, removing white blood cells (WBCs) from said blood sample to enrich a non-hematopoietic cell, if any, from said blood sample; and assessing the presence, absence and/or amount of said enriched non-hematopoietic cell.Type: ApplicationFiled: December 15, 2016Publication date: March 30, 2017Applicant: AVIVA BIOSCIENCES CORPORATIONInventors: Ping LIN, Douglas T. YAMANISHI, George WALKER, Junquan XU, Mingxian HUANG, Guoliang TAO, Lei WU, Xiaobo WANG, Joe OUYANG, Jing CHENG, Jia XU
