The measurements of the strength of the magnetic field made by the sensor may change over time (e.g., may decrease) due to changes in the positioning or alignment of the sensor or magnet. The positioning or alignment of the sensor or magnet may change due to use of the object (e.g., use of the door). One or more thresholds used by the sensor to determine the status of an object (e.g., to determine whether the door is open or closed) may be adjusted based on changes to the measurements over time.
Encoding and/or decoding a block of a video frame may be based on a previously decoded reference block in the same frame or a different frame.

Technologies are provided for identification of cyberattack campaigns. Cyberattack campaigns are represented by temporal graphs based on detection events representing suspicious activities in a computer network. Temporal relationships and property relationships among the detection events dictate the node and edge structure of a temporal graph representing a cyberattack campaign. By tracking how those relationships change over time, changes to the node and edge structure of the temporal graph can be determined. Those changes reveal the dynamics of the cyberattack campaign by identifying time-dependent changes in the connections across multiple network entities that are involved in the cyberattack campaign. Accordingly, the temporal graph may represent the entire evolution of a cyberattack campaign since its inception in a computer network.

The content item may be identified based on the captured audio of the content item in the background noises, and the identification may be used to interpret the ambiguous voice command. Additional contextual information associated with the voice commands (e.g., identifications of the users in the room) and/or the content item (e.g., the video quality of the content item, a service outputting the content item, a genre of the content item, etc.) may be used to identify the content item.

A communication procedure may be used for multiple access. A wireless device may be capable of simultaneously accessing a plurality of networks that are associated with a visited network. The visited network may or may not allow the wireless device to simultaneously access the plurality of networks, for example, based on a status of the visited network. Prior to a wireless device requesting access to a plurality of networks, a visited network may indicate whether the visited network supports, for the wireless device, simultaneous access to a plurality of networks.
A communication procedure (e.g., a small data transmission (SDT) procedure) may be used for data transmission under certain scenarios. The communication procedure may facilitate transmission of small amounts of data, for example, even if a wireless device is in a non- connected state with respect to a network. Data transmission during the communication procedure may be based on a selected transmission type and the transmission type may be changed during the communication procedure.
Methods and systems are described for recognizing, based on a voice input, a user and/or a voice command. An algorithm is described herein that processes data associated with a voice input. The data may indicate characteristics of the voice such as a gender, an age, or accent associated with the voice and other metadata. For example, the system may process the data and determine the gender of a voice. The determined characteristics may be used as an input into a voice recognition engine to improve the accuracy of identifying the user who spoke the voice input and identifying a voice command associated with the voice input. For example, the detennined gender may be used as a parameter to improve the accuracy of an identified user (e.g., the speaker) or command. The algorithm may adjust, based on gender, parameters such as confidence thresholds used to match voices and voice commands.
An identifier, for example, an identifier of a domain and/or a host of the domain (e.g., a fully qualified domain name (FQDN), etc.), such as a service management device (e.g., a server, a web server, a computing device, a web host device, a webpage, etc.), may be modified (e.g., hashed, encrypted, etc.) by a network device (e.g., a server, a domain name system (DNS) server, a DNS over hypertext transfer protocol secure (HTTPS) server/gateway (DoH server), DNS over Transport Layer Security (TLS) server/gateway (DoT server), a network management device, a computing device, etc.), sent to a user device (e.g., a client device, a smart device, a mobile device, a content output device, a computing device, a web browser, a search engine, etc.), and reused by the user device to request a service (e.g., a web service, a webpage, a file, content, a content item, etc.).

TRANSMISSION POWER CONTROL VIA SERVING AND NON-SERVING CELLS
A transmission power for a wireless communication may be determined based on one or more criteria. A default transmission power may be based on one or more default transmission power control parameters indicated by a base station. One or more default transmission power control parameters may be determined, for a transmission by a wireless device, based on whether the transmission is via a serving cell or via a non-serving cell.
