Abstract: A multi-trench 3D magic ball comprises a round ball; at least four trenches formed in a surface of the ball; each trench being formed as a close loop and being intersected with another trench; a plurality of moving units engaged in the trenches; at least two difference features being formed on the moving units; as one moving unit being moved, other moving units adjacent to the moving unit to be pushed and thus move therewith so as to along one trench received them; a moving unit in one trench being movable along another trench which is intersected with the trench it located. All the moving units fully fills the trenches; by driving one moving unit, other moving units are pushed so that after some complicated operations, the pattern of the moving units arranged on the ball is formed to match a specific arrangement.

Abstract: A method of protecting the copyright of a digital publication includes the steps of obtaining a file and a copyright licensing certificate of at least one digital publication, or obtaining at least one digital publication file and then obtaining a corresponding copyright licensing certificate at a position specified in the file; and verifying the copyright licensing certificate so as to retrieve information about the reduction process, the authority of use, the file position and contents of the digital publication recorded in the certificate, so that the digital publication file may be played, used, accessed, or shared via an operational unit. The digital publication file may be transferred or copied to other operational unit as necessary, and the copyright licensing certificate may be split, merged, etc. to allow sharing, transmitting, and transferring of the digital publication file and the copyright licensing certificate among different operational units.

Abstract: A unique card application system for the authorized cardholder logs in, no matter it is in transaction or in mere online mode, request signal can be sent and occupies the unique login address corresponding to the card in the card management center, and will refuse any other incoming request signal of other cards for logging in the same login address and dispose correspondingly; the card reader stacker can read and output data of inserted card to the network data processing center intermittently and check in the time login status check device to maintain validity of login, which can avoid refusal of legal re-login of the system in case the card reader stacker is broken down.

Abstract: The present invention relates to a drive unit of a foot massage machine which includes a housing in which a motor is installed for bringing an eccentric block into motion to drive a slider assembly at two shaft rods for a lateral shift leftwards and rightwards. The present invention is characterized in that the slider assembly is provided with a longitudinal bar at center thereof, and a crank is inserted on the outer rim of the longitudinal bar. The crank is T-shaped and includes a circular sleeve externally mounted on the longitudinal bar and a cylindrical slider serving as shaft and fixed at one side of the circular sleeve. The cylindrical slider is inserted into a mounting hole of the eccentric block, showing a sliding joint between a shaft and the mounting hole. When the eccentric block rotates with the power output shaft, the crank acts as a driven part and the circular sleeve moves upward and downward in the longitudinal bar.
