  • Publication number: 20240340663
    Abstract: 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.

  • Patent number: 12025786
    Abstract: 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.

  • Publication number: 20240196238
    Abstract: A processing system of a cellular network may receive at least a first measurement of at least one network performance indicator associated with the cellular network from at least one of: at least a first channel sounding measurement record from at least a first autonomous vehicle (AV), or a communication from at least one mobile endpoint device or at least one component of the cellular network. The processing system may next identify at a condition of a location based upon the first measurement and may direct at least one of: the first AV or a second AV to the location to capture at least a second channel sounding measurement record. The processing system may then obtain from the first AV or the second AV the at least the second channel sounding measurement record, and may adjust at least one aspect of the cellular network in response.

  • Publication number: 20240183707
    Abstract: Methods, systems, and apparatus, for a stray-light testing station. In one aspect, the stray-light testing station includes an illumination assembly including a spatially extended light source and one or more optical elements arranged to direct a beam of light from the spatially extended light source along an optical path to an optical receiver assembly including a lens receptacle configured to receive a lens module and position the lens module in the optical path downstream from the parabolic mirror so that the lens module focuses the beam of light from the spatially extended light source to an image plane, and a moveable frame supporting the optical receiver assembly including one or more adjustable alignment stages to position the optical receiver assembly relative to the illumination assembly such that the optical path of the illumination assembly is within a field of view of the optical receiver assembly.

  • Publication number: 20240056565
    Abstract: 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.

  • Publication number: 20240049122
    Abstract: 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.

  • Patent number: 11650791
    Abstract: A computing device and a method for generating relative narration. In one instance, the computing device include a display device displaying a graphical user interface including textual information received from a first application. An electronic processor of the computing device receives a user interface element associated with the textual information scheduled for relative narration. The electronic processor extracts a plurality of entities from the user interface element, converts the plurality of entities into a narrated string using a second application, generates the relative narration of the textual information using the narrated string, and output the relative narration.
