    Abstract: A method and a system for unlocking a mobile terminal on the basis of a high-quality eyeprint image may include collecting an original image of a current user by utilizing a front-facing camera when the mobile terminal needs to be unlocked; carrying out a 1080p image cropping on the original image by means of a register configured for the front-facing camera to obtain an eye image located in a special area of the original image; carrying out an eyeprint analysis and processing on the eye image to acquire eyeprint information of the current user; making a comparison between the eyeprint information and prestored eyeprint information to judge whether the comparison result shows that they are identical or not; and unlocking the mobile terminal if it is judged that they are identical.

    Abstract: A method and a system for synchronous operations of text message data, which may include, on one hand, that a feature phone receives an operation request regarding text message data from a user on the user interface, and the feature phone sends the operation request via Bluetooth to a smartphone. The smartphone can receive the operation request sent by the feature phone. The smartphone can carry out a corresponding operation, and obtain a first operation result. The smartphone can send the first operation result to the feature phone, and the feature phone can receive the first operation result. The feature phone can carry out an operation corresponding to the first operation result and can obtain a second operation result. Optionally, when local text message data of the smartphone changes, the smartphone can send a text message data modification notice to the feature phone, and the feature phone can receive the text message data modification notice. The feature phone can modify the text message data according to the text message data modification notice, and display the modified result on the user interface. In such a manner, at least one embodiment can operate text message data of the smartphone with an equivalently large screen via the feature phone with an equivalently small screen.

    Abstract: An optical lens accessory for wide-angle photography is provided. The optical lens accessory includes: an optical device having a wide-angle lens. The optical device is configured to frame a view with a range of viewing angle greater than a range of viewing angle of the camera device and let framed light into the camera device; a housing device positioned outside the optical device and causing no interference to the range of viewing angle of the wide-angle lens, the housing device is configured to support the optical device, and to isolate the framed light from external stray light, thereby preventing the external stray light from interfering with an optical path of the framed light; and a fixture device configured to attach the optical lens accessory to the camera device of the terminal device while causing no interference to the range of viewing angle of the wide-angle lens.

    Abstract: A handheld terminal, a computer and a visible light communication system are disclosed. In the handheld terminal, a first backlight apparatus is disposed on a display screen of the handheld terminal, a first data processing apparatus accesses data from a first data storage apparatus and converts the data to multiple luminance level control signals that are used to control the luminance level of the first backlight apparatus, a first control apparatus controls the first backlight apparatus to adjust its current luminance based on the multiple luminance level control signals, and the first backlight apparatus changes its luminance in accordance with the change of the data and, as a result, transmits the data to the computer in the form of visible light. Thus, the present disclosure eliminates the need of cumbersome physical connection ports and intermediate connection cables, and enables stable, reliable and highly secure visible light communications.
