Abstract: An online system allows third-party systems to provide content for distribution to users. The online system allows trademark owners to search for content items that are likely to violate trademarks. The online system receives proof of the trademark registration from trademark owner's devices. The online system receives a search request for content items that are likely to violate a trademark. The online system ranks the content items that are likely to violate the input trademark based on various factors. One of the factors used for ranking the content items is a score generated by a machine learning based model that indicates a likelihood of violation of trademarks by a content item. The online system controls the rate of distribution of content items of a content provider based on information indicating whether the content provider violates trademarks, for example, by blocking distribution of content items by specific content providers.

Abstract: Exemplary embodiments relate to techniques for providing modifiable views when capturing an image of a video call. When a user takes a picture of a video call (e.g., a screen shot), associated applications may scrape the phone of the call participants to acquire a better-quality image than what might be displayed in the call interface, which may be of reduced quality due to compression and/or bandwidth limitations. Problematically, the layout of the call interface is different on each user's device, which can cause the resulting screenshot to not look as expected. Exemplary embodiments therefore place the data scraped from each device into movable elements, which can be rearranged on the screen to alter the layout (even post-capture). Moreover, new layouts are possible, potentially with additional graphical elements. In some embodiments, information gathered from a user's social networking information can determine the layout parameters.

Abstract: A laser is used to induce bonding of LED contact pads with corresponding substrate contact pads on a display substrate. The wavelength of the laser light and the material used for the contact pads are both selected so that the laser light is capable of melting the contact pads. For example, the laser light has a wavelength of between 220 nm and 1200 nm, and the contact pads are formed of a copper-tin oxide (CuSn). Furthermore, the system may be configured to shine the laser light through a number of other components, such as the pick-up head and the LED itself. These materials can be formed of materials that do not absorb the energy of the laser light. Bonding the contacts with a laser in this manner allows for faster heating and cooling times, avoids reheating of previously bonded contact pads, and reduces thermal expansion of the display substrate.
