  • Patent number: 11910193
    Abstract: Methods and systems of segmenting computing devices in a wireless network having an access point broadcasting in a single domain are described. In an exemplary method, a request to join the wireless network is received from a computing device. The request is associated with an identifier. When the identifier is not associated with a virtual network within the wireless network, a virtual network is configured within the wireless network and the identifier is associated thereto and the computing device is assigned thereto. When the identifier is associated with an existing virtual network within the wireless network, the computing device is assigned to the existing virtual network.

  • Patent number: 11910302
    Abstract: In some examples, in response to determining that a new communication channel is required, a wireless device retrieves information provided from a network node of availability of alternative communication channels for the wireless device. In response to retrieving information that a second communication channel is available for a location within which the wireless device is located, the wireless device removes wireless device specific information and initiates a request to connect to the second communication channel, where the second communication channel is in a frequency range different from a frequency range of the first communication channel.

  • Patent number: 11886563
    Abstract: A continuous authentication system and related methods are provided. The system detects requests to perform user actions. A security value is associated with each user action. The system determines a subsequent session security level in response to an adjustment to a session security level by a security value of a requested user action. The requested user action is permitted and the session security level is adjusted based on the security value of the requested user action in response to a determination by the system that the subsequent session security level is greater than or equal to a threshold session security level. A user authentication challenge is caused (e.g., prompted) in response to a determination by the system that the subsequent session security level is less than the threshold session security level.

  • Publication number: 20240005565
    Abstract: Methods and devices for encoding a point cloud. A bit sequence signaling an occupancy pattern for sub-volumes of a volume is coded using binary entropy coding. Contexts may be based on neighbour configuration and a partial sequence of previously-coded bits of the bit sequence. A determination is made as to whether to apply a context reduction operation and, if so, the operation reduces the number of available contexts. Example context reduction operations include reducing neighbour configurations based on shielding by sub-volumes associated with previously-coded bits, special handling for empty neighbour configurations, and statistics-based context consolidation.
