  • Patent number: 11979158
    Abstract: An integrated circuit (IC) device includes a master latch circuit having a first clock input and a data output, a slave latch circuit having a second clock input and a data input electrically coupled to the data output of the master latch circuit, and a clock circuit. The clock circuit is electrically coupled to the first clock input by a first electrical connection configured to have a first time delay between the clock circuit and the first clock input. The clock circuit is electrically coupled to the second clock input by a second electrical connection configured to have a second time delay between the clock circuit and the second clock input. The first time delay is longer than the second time delay.

  • Publication number: 20240137400
    Abstract: A media item to be provided to users of a platform is identified. The media item is associated with a media class of one or more media classes. An indication of the media item is provided as input to a machine learning model trained based on historical encoding data to predict, for a given media item, a set of encoder parameter settings that satisfy a performance criterion in view of a respective media class of the given media item. The historical encoding data includes a prior set of encoder parameter settings that satisfied the performance criterion with respect to a prior media item associated with the respective class. Encoder parameter settings that satisfy the performance criterion in view of the media class is determined based on an output of the model. The media item is caused to be encoded using the determined encoder parameter settings.

  • Patent number: 11940388
    Abstract: Example methods are provided to improve placement of an adaptor (210,220) to a mobile computing device (100) to measure a test strip (221) coupled to the adaptor (220) with a camera (104) and a screen (108) on a face of the mobile computing device (100). The method may include displaying a light area on a first portion of the screen (108). The first portion may be adjacent to the camera (104). The light area and the camera (104) may be aligned with a key area of the test strip (221) so that the camera (104) is configured to capture an image of the key area. The method may further include providing first guiding information for a user to place the adaptor (210,220) to the mobile computing device (100) according to a position of the light area on the screen (108).
