  • Patent number: 10902470
    Abstract: A system and method is provided for dynamically managing advertiser affiliate links for online marketing. A global redirect server accepts a visitor's web browser request for a product or non-product webpage associated with an affiliate network advertiser URL, and returns a corresponding product or non-product webpage to the visitor that is corrected for the visitor's geographic region if such a webpage exists, or returns the originally requested webpage if it does not. The server determines the visitor's geographic region based upon request metadata, and can generate a corrected webpage that affords analytic and commission tracking even if no corresponding affiliate network exists in the determined geographic region. The server includes a database for locating products within the determined geographic region that are comparable to the product of the product webpage request, in the event that the exact product is not available in the geographic region.

  • Patent number: 10891633
    Abstract: A method, apparatus, and system are directed towards providing advertisement insertions at a point of consumption into digital content, such as broadcast television content. A content provider may initially mark the content for advertisement insertion, and create a metadata file indicating constraints, targets, expirations, or the like. A downstream user employs a plug-in component and provides an initial user profile, in part, to access the content with advertisements. As the content is played, and an advertising marker is encountered, fast forwarding or other skipping features are disabled, and an advertisement stream is spliced into the content stream. The advertisement stream is determined based on the user profile and/or other metadata. Moreover, the advertisement stream may be obtained over a network such that advertisements may be refreshed even years after the content has been acquired by the user. In one embodiment, the advertisement consumption may be tracked and reported.

  • Patent number: 10871331
    Abstract: A cooling device and a motor are provided. The cooling device that cools a heating element is provided with: a cooling chamber for cooling the heating element with a first cooling medium; a radiator chamber for releasing the heat of the first cooling medium to the outside; and a first connection path and a second connection path for connecting the cooling chamber and the radiator chamber. When part of the first cooling medium in the cooling chamber is gasified, at least part of the gasified first cooling medium moves into the first connection path, thus causing a circulation in which the first cooling medium in the cooling chamber flows into the radiator chamber via the first connection path, and the first cooling medium in the radiator chamber flows into the cooling chamber via the second connection path.

  • Patent number: 10861061
    Abstract: A first instance of a messenger application having a plug-in communicates with a second instance of the messenger application lacking the plug-in. The plug-in provides enhanced functionality to the first instance of the messenger application, while also providing corresponding functionality to the second instance, which lacks the plug-in. For example, the plug-in may provide rich, non-thread-native content to the first instance, while also providing corresponding thread-native content to the second instance. As another example, the plug-in may obtain data from the second instance and provide tailored advertisements to the second instance based upon that data. An another example, the plug-in may obtain location data from one or more of the instances and provide access to location-specific services that take the location data into account.

  • Patent number: 10862368
    Abstract: Disclosed is a brushless DC vibration motor. An eccentric weight of a rotor is securely sandwiched between a back yoke and a permanent magnet, being heavier to provide an increased vibrational force. A bearing coupling portion with upper and lower stopping protrusions prevents detachment of a bearing. A bracket is formed with grooves, instead of through holes, to strongly support a cogging plate of which pieces are connected with each other to form a single body for easy-placement on the bracket. An optimized area of the cogging plate can suppress the rotor not to rise during starting of the motor, resulting in no frictional noise, and a high stopping speed and uniform horizontal level of the rotating rotor.
