  • Patent number: 11804328
    Abstract: The present invention provides an inductance coil comprising a magnetic core and a coil, wherein the coil is formed by winding a flat wire, and the flat surface of the wire is perpendicular to the axis around which the coil is wound. The coil is wrapped with an insulating adhesive tape and the tape is wound on the wire around an axis which is substantially in line with the direction along which the wire forming the coil extends, so as to form an isolation layer on the surface of the coil. Additionally, the present invention provides an electromagnetic device including the above inductance coil.

  • Publication number: 20220350952
    Abstract: In general, various aspects of the present invention provide methods, apparatuses, systems, computing devices, computing entities, and/or the like for intercepting HTTP traffic (e.g., including HTTP requests and responses) for displaying a third-party website in an embedded element (e.g., inline frame) of a website. The extension may, for example, intercept HTTP requests in order to inject one or more required cookies and/or other HTTP headers in order to pass session information and other information along with the HTTP request. The browser extension may, in various other embodiments, be configured to: (1) intercept an HTTP response (e.g., to a modified HTTP request sent via the browser extension); (2) modify the HTTP response; and (3) cause a web browser to render a target website based at least in part on the modified HTTP response.

  • Patent number: 11284702
    Abstract: A robot cleaner including a body, a driven wheel, and a side brush coupled to the body. The side brush includes a hub configured to rotate about a pivot axis and a plurality of bristles. Some bristles may form a first angle with the pivot axis and others form a second angle with the pivot axis which is larger than the first angle. Some bristles may have a first bristle length and others have a second bristle length which is larger than the first bristle length. The robot cleaner may include a side brush deflector to deflect debris propelled by the side brush towards the vacuum inlet. The side brush deflector includes a plurality of deflector bristles extending downwardly from a floor facing surface of the robot cleaner towards a floor such that some of the bristles pass through or underneath a portion of the deflector bristles.

  • Publication number: 20210012439
    Abstract: A path optimization computer to enable recommendations of different types of entities (for example, flights, hotels, and travel budgets) based on dynamic data to different groups of user devices when optimizing a path based on a plurality of geolocations. Entity designators directly adjust the relative weights in variables of entities when optimization is computed, and then assigning that configuration, as a parameter package, to a group of user devices whereby manager devices can promote appropriate options for user devices based on established thresholds. Thresholds may change dynamically from request to request based on information received from external resources and availability, and from group to group.
