Abstract: Disclosed is a decryptor device configured for a user to solve a preset set of secret codes, the preset set of secret codes including a plurality of secret codes selected from a given code set. The device includes: a housing; a power supply module; a main control module; a code input module electrically connected to the power supply module and communicatively connected to the main control module, the code input module configured to input at least a solution code set, the solution codes being selected from the given code set; and a display module electrically connected with the power supply module and communicatively connected with the main control module, the display module including at least one set of display units. The display module operates in association with the code input module to display each set of solution codes as they are input.

Abstract: An intelligent magic cube, and a sensing shaft center structure and a timing method used thereby. The sensing shaft center structure comprises a main body; the main body comprises a core (1) having an internal cavity, and several tubular shafts (2) communicated with the core (1). An internal central control module (3) is provided inside the cavity, and comprises a state obtaining unit. Each tubular shaft (2) is provided with a state signal sending set (4). The state signal sending set (4) comprises a signal selector and multiple signal exciters. The signal selector may be paired with any signal exciter, and generate a corresponding state signal. The state obtaining unit is configured to be able to receive the state signal sent from the state signal sending set (4).
