Publication number: 20240340663Abstract: In one example, the present disclosure describes a device, computer-readable medium, and method for proactively adjusting the infrastructure of a communications network in response to reporting of real-time network performance. For instance, in one example, a method includes obtaining real-time network performance metrics directly from a user endpoint device operated by a customer of a telecommunication service provider network, correlating the real-time network performance metrics with data from another data source, wherein the data includes data other than network performance metrics, and adjusting an infrastructure of the telecommunication service provider network in response to an insight gleaned through the correlating.Type: ApplicationFiled: June 17, 2024Publication date: October 10, 2024Inventors: Rajan Anand, Nimish Buch, Timothy Neville, Mark Cottrell, David Lu, Eshrat Huda, Sachin Lohe

Patent number: 12025786Abstract: A portable variable focus microscope includes a housing having a lower section and an upper section secured together. A lens is removably disposed on at least one lens retention feature of the upper section. The scope further includes a slide platform and a height adjuster, where rotation of the height adjuster within the scope housing adjusts a relative distance between the slide platform and the lens to adjust a focus of the lens. The scope may be used in conjunction with a mobile data device to capture an image of a sample on a slide received in the scope. A program including a CNN algorithm may be employed to identify contaminants in the sample.Type: GrantFiled: February 5, 2021Date of Patent: July 2, 2024Assignee: H2Ok Innovations Inc.Inventors: David Lu, Annie Lu, Lin Zhu, Anurag Mitra

Publication number: 20240056565Abstract: Example embodiments relate to identifying defects in optical detector systems based on extent of stray light. An example embodiment includes a method. The method includes capturing, using an optical detector system, an image of a scene that includes a bright object. The method also includes determining a location of the bright object within the image. Further, the method includes determining, based on the location of the bright object within the image, an extent of stray light from the bright object that is represented in the image. In addition, the method includes determining, by comparing the extent of stray light from the bright object that is represented in the image to a predetermined threshold extent of stray light, whether one or more defects are present within the optical detector system. The predetermined threshold extent of stray light corresponds to an expected extent of stray light.Type: ApplicationFiled: October 23, 2023Publication date: February 15, 2024Inventors: Chen David Lu, Matthew Rinehart, Volker Grabe

Publication number: 20240049122Abstract: Facilitating radio access network on-demand dynamic bandwidth allocation in advanced networks is provided herein. Operations of a system include determining that a group of network slice resources associated with network equipment fail to satisfy a specification applicable to a user equipment. The operations can also include extracting a first group of resource blocks from a first network slice resource of the group of network slice resources. Further, the operations can include reallocating the first group of resource blocks to a second network slice resource of the group of network slice resources. A combination of the first group of resource blocks and a second group of resource blocks of the second network slice resource is determined to satisfy the specification applicable to the user equipment.Type: ApplicationFiled: August 4, 2022Publication date: February 8, 2024Inventors: Eshrat Huda, Moshiur Rahman, Prafulla Verma, David Lu, Russell Fischer
