  • Patent number: 10805197
    Abstract: Embodiments relate to systems and methods for electronically conditioning transmission of communications based on results of a connection assessment. An electronic file is executed at an electronic device, which causes a first query and a second query to be presented. A first query response and a second query response are identified. The first query response is stored in a locked configuration that inhibits the ability to modify the first query response to the first query. The second query response is stored but is not stored in the locked configuration. Query response data is generated that includes an identifier of the second query, an identifier of the second query response and an identifier of the electronic device. A connection variable is determined by assessing one or more network connections available to the electronic device. When a transmission condition is satisfied, the query response data is transmitted to another device.

    Abstract: Techniques are disclosed for validating a ticket based on biometric data provided by a ticket holding user. A ticket controller device broadcasts an inquiry frame specifying a request for authentication data for a ticket user requesting access to a service hosted by the ticket controller. A mobile device may receive the inquiry frame and generate a response frame encapsulating a ticket identifier and biometric data associated with a user. The ticket controller receives the response frame including the ticket identifier and the biometric data. Upon determining that the ticket identifier and the biometric data encapsulated in the response frame matches a stored ticket identifier and biometric data, the ticket controller grants the user access to the service.

  • Patent number: 10511425
    Abstract: Embodiments of the present invention provide a channel-state information process processing method, a network device, and a user equipment, where the channel-state information process processing method includes: after receiving a first channel-state information CSI request sent by a first network device, if CSI corresponding to multiple aperiodic CSI processes has not been reported by a user equipment, dropping CSI corresponding to a part of aperiodic CSI processes among the multiple aperiodic CSI processes, where each CSI process is associated with a channel measurement resource and an interference measurement resource. A problem existing after a CoMP technology is introduced can be solved that the UE cannot implement processing of multiple CSI processes.

  • Patent number: 10506568
    Abstract: Various methods of allocating uplink control channels in a communication system are implemented at a resource scheduler or a user equipment (UE). In one method the scheduler reserves resources for a downlink data channel and signals a corresponding downlink data channel grant and also reserves resources for a persistent uplink control channel for a longer duration than the data channel grant. Signaling overhead associated with a grant for this persistent uplink control channel is reduced over a full dynamic grant. A predetermined rule can be used at the scheduler and at the UE to avoid overhead signaling associated with a grant for this persistent control channel. Predetermined rules at the UE and scheduler can also be used to reserve appropriate resources and select appropriate MCS levels for control information and the control information and uplink data can be transported over a common uplink channel when a time overlap occurs between an uplink data channel and the persistent control channel.

  • Patent number: 10492034
    Abstract: Apparatus and methods for providing information via an open-access network such as a wireless local area network (WLAN). In one embodiment, the information provided is contextually relevant to one or locations, more users or devices receiving the information. In one implementation, the information is provisioned by a network entity (for example, from a service provider network operator) and provided to one or more access points (APs) of the service provider network. The information is bit-stuffed into Wi-Fi beacon frames or other data structures that are broadcast by the APs to nearby client devices. A receiving client device extracts the information using a protocol embodied in application software on the client, and may also initiate a dedicated wireless connection with the AP for e.g., transmission of content related to the context and/or the bit-stuffed information, access of related Internet addresses, etc.

  • Patent number: 10491371
    Abstract: A wireless media distribution system is provided comprising an access point (6) for broadcasting media and a plurality of stations (2) for reception and playback of media. Each station is configured for receiving and decoding a timestamp in a beacon frame transmitted repeatedly from the access point. This is used to control the output signal of a station physical layer clock (12) which is then used as a clock source for an application layer time synchronisation protocol. This application layer time synchronisation protocol can then be used in the station to control an operating system clock (8) for regulating playback of media.

  • Patent number: 10476906
    Abstract: A method to ensure availability of a plurality of computing nodes operating within a cluster that analyzes suspicious objects received from geographically remote sensors for malware is described. Responsive to a change in operability of a cluster, a determination is made whether the change is directed to a broker computing node or an analytic computing node. Where the change is a failover experienced by a broker computing node, a determination is made whether the cluster includes a plurality of broker computing nodes, and if not, an analytic computing node is configured to operate as a second broker computing node. For a takeover event, however, a determination is made whether the cluster includes a plurality of broker computing nodes, and if not, the analytic computing node operates as the second broker computing node. The first broker computing node is subsequently placed into an off-line status until maintenance has completed.

  • Patent number: 10466716
    Abstract: Commanding vehicles via a vehicle-to-infrastructure communication network are provided. A roadside unit in a location on a vehicular travel path broadcasts timestamps. A vehicle having an onboard unit receives the timestamp, calibrates an internal clock, and transmits a status of the first vehicle to the first roadside computing unit. The roadside unit receives the status of the vehicle, and transmits, to a data processing system, data packets including the status and information associated with the location in the vehicular travel path. The data processing system inputs the status information and the information associated with the location into a deep learning engine to assign, based on an output from the deep learning engine, a label to the vehicle. The data processing system selects a vehicle command based on the label and transmits the vehicle command to the vehicle to execute an action for traversing the vehicular travel path.

    Abstract: Systems and methods are provided and include receiving, at a user device, a first user input from a user, the first user input selecting an application icon displayed at the user device. In response to receiving the first user input, the user device launches the native application and sets the native application into the home state. The user device receives a second user input configured to set the native application into a state of the native application other than the home state. In response to receiving the second user input, the user device sets the native application into the other state using the user device. The user device determines that the user frequently sets the native application into the other state, and configures the application icon to, upon being selected, cause the user device to launch the native application and set the native application into the other state.
