  • Patent number: 10542458
    Abstract: This application discloses a data communication method implemented at an electronic device. The electronic device obtains a sequence of data packets. Each data packet complies with a first data format corresponding to a network access protocol and comprises a respective header that further includes a data length field for specifying a length of the respective data packet. Data are then assigned to the data length fields of the sequence of data packets according to a second data format. The electronic device encrypts the sequence of data packets including the assigned data. The encrypted data packets are then sent to a receiver device that is communicatively coupled to the electronic device via a wireless network. The receiver device is configured to retrieve the assigned data from the data length fields of the data packets according to the first and second data formats and perform operations in accordance with the retrieved data.

  • Publication number: 20160103970
    Abstract: Methods, devices and systems for sharing information related to exercise/health activities are disclosed. A user terminal can acquire a device identifier associated with a health monitoring device, such as a monitoring wristband or a treadmill, through a communication program (e.g., an instant messaging application). The user terminal can communicate with a server of the communication program so that the server binds the device identifier with a user ID. The association of the user ID and the device identifier allows the user to share the health monitoring information from the health monitoring device with other users through the server. In addition, the connected users can participate in real-time competitions and share information related to the competition. The server also generates ranking lists or other sharing formats for the competition, improving user experience and making exercise and competition more attractive.
