  • Publication number: 20190316748
    Abstract: An electronic lighting device and a method for manufacturing the same are disclosed. The electronic lighting device may comprise a core, which may comprises an enclosure, a light-emitting element, a flame sheet and a swing mechanism. The flame sheet is movably supported or suspended on the enclosure, and may comprise an upper sheet which is of a flame-like shape. The upper sheet is configured to expose above the top of the enclosure. The light-emitting element may be installed on the enclosure. A light outgoing direction of the light-emitting element may be intersected with the surface of the upper sheet so that the light of the light-emitting element is projected on the surface of the upper sheet. The swing mechanism is disposed beneath the flame sheet and can apply a force on the flame sheet to actuate the flame sheet to sway or swing. By the present application, a visual experience of true fire can be achieved and an interestedness and appreciation can be improved.

  • Publication number: 20190104406
    Abstract: An intelligent terminal scans, as a scanned identification code, an identification code that is displayed by an intelligent wearable device. A wireless broadcast signal is transmitted by the intelligent terminal to identify the intelligent wearable device. A response to the wireless broadcast signal is received by the intelligent terminal and from the intelligent wearable device, where the response includes an identification code. The identification code is extracted by the intelligent terminal from the response and as an extracted identification code. The intelligent terminal compares the scanned identification code and the extracted identification code. If it is determined that the scanned identification code and the extracted identification code are the same, the intelligent terminal is paired with the intelligent wearable device.

  • Publication number: 20190081979
    Abstract: Service data is received by a server and from a client computing device, where the service data includes a unique identifier and a variable identifier stored in a local secure storage of the client computing device. The server parses the service data to obtain the unique identifier and the variable identifier as parsed data. The server determines whether the unique identifier and the variable identifier in the parsed data are identical to a unique identifier and a variable identifier associated with the client computing device and recorded by the server as recorded data. If the result of the determination is not identical, the server indicates that the local secure storage of the client computing device is under a copy attack, and performing a predetermined response action. If the result of the determination is identical, the server transmits a new variable identifier to the client computing device.
