Abstract: A player profile management system collects player data from various systems and generates and manages player profiles. A snapshot pipeline of the player profile management system generates a snapshot player profile associated with a player. The player profile management system receives, after generating the snapshot player profile associated with the player, player data associated with the player. An update pipeline of the player profile management system generates, based on the snapshot player profile and the player data associated with the player, an update player profile associated with the player.

Abstract: An encrypted photographing method based on fingerprint recognition, and a system thereof are disclosed. The method may include: when detecting starting an encrypted photographing mode, obtaining an unlocking fingerprint for starting the encrypted photographing mode; when detecting a photographing instruction, generating an original photo and generating a key pair based on the unlocking fingerprint wherein the key pair may include an encryption key and a decryption key; encrypting the original photo according to the encryption key so as to generate an encrypted photo; and generating a corresponding system directory according to the decryption key, and saving the encrypted photo to the generated system directory. The present disclosure improves the security of a photo, and avoids leaking the content of an encrypted photo.

Abstract: A double-antenna radio frequency power detection circuit comprises a radio frequency transceiver, a switching module, a first power detection module, a second power detection module, a first antenna, and a second antenna. The switching module outputs a radio frequency signal received from the radio frequency transceiver, to the first power detection module or the second power detection module according to a switching signal. The first power detection module or the second power detection module respectively detects the transmit power of the radio frequency signal passing through the first antenna or the second antenna, and gives a feedback to the radio frequency transceiver.

Abstract: Provided is an underwater repair system for a cavity region of a concrete panel rock-fill dam panel, including a moving platform, a work cabin, a pressure drainage apparatus, a traction apparatus, and a positioning apparatus; the traction apparatus controlling the movement of the moving platform on the surface of a dam concrete panel; the positioning apparatus transmits a detection position; the work cabin is a pressure cabin, the work cabin being connected to the pressure drainage apparatus, and a drill apparatus and grouting apparatus being arranged in the work cabin; the moving platform moves into the cavity region, and the pressure drainage apparatus starts up to drain the water in the work cabin, a partially closed waterless space being formed inside the work cabin, the drill apparatus drilling the concrete panel at the upper end of the cavity region and the grouting apparatus subsequently implementing grouting to complete the repair.
