Abstract: A method for providing aircraft network communications is provided. The method includes checking, by an onboard server of an aircraft, for aircraft network connection readiness; receiving, by the onboard server, a connection request from one or more user devices on the aircraft that subsequently and periodically continue scanning for aircraft network connection readiness; in response to finding, by the onboard server, a secure connection to an aircraft communications network based on one or more connection rules, connecting the onboard server to the aircraft communications network; notifying the one or more user devices that a network is available; authenticating the one or more user devices; connecting the one or more user devices to the aircraft network; monitoring network connection status; and in response to determining that the network connection status is insecure based on the one or more connection rules, disconnecting the onboard server from the aircraft communications network.

Abstract: A method to generate a collaborative 3D map comprises providing a 3D map data fusion platform; providing a basic satellite map of a world location; publishing a detailed real-time virtual replica network (RVRN) of a real world place with reference to the basic satellite map; obtaining the pose (e.g., position and orientation) of a client device; and performing a simultaneous location and mapping (SLAM) process of a first coordinate space. The SLAM process uses image data from an imaging device of the client device, the pose of the client device, and/or the data of the basic satellite map to determine the pose of a plurality of features within the first coordinate space. The method further includes creating a new map comprising three-dimensional coordinates of the plurality of features within the first coordinate space and merging the new map with the published RVRN, creating a fused 3D map.

Abstract: Systems and methods for optimizing virtual world computations through an n-tier architecture including at least three tiers are provided. In a sample three-tier architecture, a first tier comprises a client software engine configured to receive input data, send the data to the second tier, and perform end-user processing. A second tier connects to the first tier and to a third tier through a network and comprises a client-dedicated module that is dynamically instantiated and which is configured to either prepare the received data for subsequent processing from the client software engine or send the received data to the third tier. The third tier comprises a virtual world processing module configured to receive and process data from the second tier, generating world state updates, and to dynamically instantiate the client-dedicated module to spawn client-dedicated instances. The world state updates are sent to corresponding client-dedicated module instances for further processing.

Abstract: A system enabling a distributed 3D engine for performing dynamic load balancing through virtual worlds are provided. The system comprises one or more server computers comprising memory and at least one processor, the memory storing a data structure representing at least one portion of a virtual or real world as a plurality of cells storing virtual objects. The memory further stores a distributed 3D engine comprising a resource manager implemented in a distributed deployment and a plurality of individual software engines. Resources are dynamically allocated via the distributed deployment to one or more cells based on a current load and a corresponding computed and ranked demand. In some embodiments, the demand further considers one or more of an amount of virtual objects and level of interactions within the portion of the persistent virtual world system visible to a user avatar. Methods thereof are also provided.

Abstract: A cross-lingual voice conversion system and method comprises a voice feature extractor configured to receive a first voice audio segment in a first language and a second voice audio segment in a second language, and extract, respectively, audio features comprising first-voice, speaker-dependent acoustic features and second-voice, speaker-independent linguistic features. One or more generators are configured to receive extracted features, and produce therefrom a third voice candidate keeping the first-voice, speaker-dependent acoustic features and the second-voice, speaker-independent linguistic features, wherein the third voice candidate speaks the second language. One or more discriminators are configured to compare the third voice candidate with the ground truth data, and provide results of the comparison back to the generator for refining the third voice candidate.

Abstract: A method for enabling the enhanced user-to-user communication in digital realities comprising generating a marker of a target user that is persistently applied on the target user; detecting, through a wireless network, the presence of a target user device and counterpart user device connected to the server via the wireless network; sending a notification to the counterpart user device informing about the presence of the target user device based on a set of rules; receiving one or more forms of interaction from the counterpart user device on the marker of the target user; opening up a communication channel between the counterpart user device and target user device; and receiving, processing and accordingly redirecting corresponding communications through and between the counterpart user device and target user device. A system thereof is also disclosed.

Abstract: A spatially-aware multimedia router system includes at least one media server computer configured to receive and analyze incoming data comprising incoming multimedia streams from client devices, and adapt outbound multimedia streams for individual client devices based on the incoming data received from the client devices. The incoming multimedia streams include elements from within a virtual environment. The outbound multimedia streams are adapted for the individual client devices based on user priority data and spatial orientation data that describes spatial relationships between corresponding user graphical representations and sources of the incoming multimedia streams within the virtual environment.

Abstract: A method for accessing communication networks includes receiving by a device an identification of a communication network; determining whether the identification corresponds to a registered communication network; if the identification corresponds to a registered communication network, generating a password for accessing the communication network by applying a cryptographic function parameterized with a secret value associated with the communication network to the identification; and automatically establishing a connection of the device to the communication network using the generated password. Furthermore, methods for managing access to communication networks and providing communication networks are disclosed. A corresponding client device, service infrastructure and service provider infrastructure are also detailed.
