  • Patent number: 10736854
    Abstract: Nanocrystals, compositions, and methods that aid particle transport in mucus are provided. In some embodiments, the compositions and methods involve making mucus-penetrating particles (MPP) without any polymeric carriers, or with minimal use of polymeric carriers. The compositions and methods may include, in some embodiments, modifying the surface coatings of particles formed of pharmaceutical agents that have a low water solubility. Such methods and compositions can be used to achieve efficient transport of particles of pharmaceutical agents though mucus barriers in the body for a wide spectrum of applications, including drug delivery, imaging, and diagnostic applications. In certain embodiments, a pharmaceutical composition including such particles is well-suited for administration routes involving the particles passing through a mucosal barrier.

  • Publication number: 20200235914
    Abstract: Apparatuses, systems, and methods for generating and utilizing improved initialization vectors (IVs) when performing encryption and authentication in wireless communications. In some scenarios, a wireless communication device may generate one or more pseudorandom multi-bit values, e.g., using a respective plurality of key derivation functions (KDFs). A first portion of each value may be used as a respective key for encryption or authentication of traffic on the user plane or the control plane. A second portion of each value may be used as a nonce value in a respective IV for use with a respective key for encryption or authentication of traffic on the user plane or the control plane. In some scenarios, the nonce values may instead be generated as part of an additional pseudorandom value (e.g., by executing an additional KDF), from which all of the IVs may be drawn.

  • Patent number: 10721142
    Abstract: A system for troubleshooting network problems is disclosed. A model can use demographic information, network usage information, and network membership information to determine an importance of a problem. The importance of the problem for the user who reported the problem, a number of other users affected by the problem, and the importance of the problem to the other users can be used to determine a priority for resolving the problem. Before and after a work order is executed to resolve the problem, network metrics can be gathered, including aggregate network metrics, and automatically presented in various user interfaces. The analysis of the metrics can be used to update a database of which work orders are assigned in response to which problems.

  • Patent number: 10679428
    Abstract: Systems, devices, media, and methods are presented for object detection and inserting graphical elements into an image stream in response to detecting the object. The systems and methods detect an object of interest in received frames of a video stream. The systems and methods identify a bounding box for the object of interest and estimate a three-dimensional position of the object of interest based on a scale of the object of interest. The systems and methods generate one or more graphical elements having a size based on the scale of the object of interest and a position based on the three-dimensional position estimated for the object of interest. The one or more graphical elements are generated within the video stream to form a modified video stream. The systems and methods cause presentation of the modified video stream including the object of interest and the one or more graphical elements.
