Patent number: 10325390Abstract: Various embodiments may include methods executed by processors of computing devices for geometry based work execution prioritization. The processor may receive events, such as images. The processor may overlay a boundary shape on the event to identify discard regions of the event lying outside the boundary shape. The processor may identify work regions of the events lying within the working boundary shape. The devices may determine a cancellation likelihood for each of the identified work regions of the events. The processor may assign a trimming weight to each of the identified work regions based on the determined cancellation likelihoods. The processor may then add each of the identified work regions as a work item to an execution work list in an order based on the assigned trimming weights. The work items may be processed in order of trimming weight priority.Type: GrantFiled: June 24, 2016Date of Patent: June 18, 2019Assignee: QUALCOMM IncorporatedInventors: Tushar Kumar, Wenhao Jia, Arun Raman, Hui Chao, Wenjia Ruan

Publication number: 20180318835Abstract: The invention relates to microfluidic devices and array disks for “one-pot” isolated chemical reactions. The array disks comprise a plurality of sectors in which each sector comprises one microfluidic device. The microfluidic devices comprise a fluid delivery channel and an array of wells wherein the fluid delivery channel delivery fluid into the wells in a serpentine arrangement. In some embodiments, the fluid delivery channel is directly above the array of wells. In other embodiments, the fluid delivery channel is offset from the array of wells so that side channels branching from the fluid delivery channel delivers fluid into the wells. The well of the microfluidic device comprises a gas-permeable membrane that forms the floor, well, or at least a portion of the floor or wall of the well. In preferred embodiments, the well is cylindrical.Type: ApplicationFiled: July 13, 2018Publication date: November 8, 2018Inventors: Rhett Martineau, Jeff Houkal, Shih-Hui Chao, Weimin Gao, Shufang Ci, Deirdre Meldrum

Publication number: 20180144521Abstract: Various embodiments may include methods executed by processors of computing devices for geometry based work execution prioritization of irregular shapes on a computing device. Various embodiments may include calculating cost functions for an irregularly shaped work region detected by the computing device. The processor may map the irregularly shaped work region to a geometrically-bounded first work region within an N-dimensional space. The processor may then assess the efficacy of implementing modification strategies such as merging work regions or splitting a large work region into sections. Two or more smaller work regions may be merged to create a larger work region that may be more easily processed by a processing unit. Similarly, large shapes may be split into multiple smaller regularly shaped work regions that may be processed by different processors.Type: ApplicationFiled: November 22, 2016Publication date: May 24, 2018Inventors: Hui Chao, Tushar Kumar, Wenjia Ruan, Arun Raman
