    Abstract: A mesh network device includes a content repository including a first section to store original data and a second section to store cached data, and an application processor including a user space, kernel space, and an on-path data caching engine. The on-path data caching engine is to receive, from a second mesh network device, data frames via a data link layer of a TCP/IP mesh network. The data frames include audio or video content. The on-path data caching engine is further to store the data frames in a socket kernel buffer, determine that a third mesh network device is a destination for the data frames, and forward the data frames to the third mesh network device. The on-path data caching engine is to determine that the audio or video content is to be cached and asynchronously copy the audio or video content to the second section of the content repository.

    Abstract: Described are techniques for determining occurrence of an error associated with a user device and user interfaces to present to users responsive to the error to acquire additional information. Particular user interfaces that correspond to an error may be determined based on the characteristics of the error. Particular communication channels by which the user interfaces may be provided to a user may be determined based on the devices affected by the error, the characteristics of the user interfaces, and the characteristics of the receiving devices. User input received responsive to a user interface may be associated with a particular error or user device and used to determine an action to be performed responsive to the error.

    Abstract: Disclosed are various embodiments for determining whether a client device is authorized to receive media content based at least in part on the call signs of broadcast stations that the client device is able to receive. A computing device receives a broadcast station identifier and a program identifier from a client computing device. The computing device determines that the client computing device is authorized to access media content identified by the program identifier based at least in part on the broadcast station identifier. Finally, the computing device streams the media content to the client computing device in response to determining that the client computing device is authorized to access the media content.

    Abstract: Uncrewed autonomous vehicles (“UAVs”) may navigate from one location to another location. Described herein are systems, devices, and methods providing countermeasures for threats that may compromise the UAVs. A plurality of UAVs may establish a mesh network to distribute information to one another. A first UAV may receive external data from a second UAV using the mesh network. The external data may be used to confirm or cross-check data such as location, heading, altitude, and so forth. Disagreement between data generated by the first UAV with external data from the second UAV may result in the determination that the first UAV is compromised. Remedial actions may be taken, such as the first UAV may be directed to a safe location to land or park, may receive commands from another UAV, and so forth.
