Abstract: An information transmission method, executed by a servo system, is provided that includes the following steps of: providing an application program to be downloaded, installed and executed in an electronic device, in which, after the electronic device executes the application program and a consent key is pressed, a device datum including the classification of the electronic device is sent to a servo system; recording the device datum in a user database; and pushing a push message corresponding to the classification of the electronic device to the electronic device.

Abstract: A method for collecting usage information of portable devices is provided, wherein the method is performed by at least one server, and includes following steps: (A) providing an application to be downloaded by a device, wherein the application returns a used page message to the at least one server when the device is executed, and the content of the used page message includes identification data of the device, application software which is currently used and operated, a currently used page, environment parameters, and at least one of operational actions on the used page and a retention time on the used page; (B) receiving the used page message from the device; and (C) storing the used page message. The information which users are really interested in can be collected in the present invention, thereby achieving the objective of dispatch accuracy for marketing messages.

Abstract: Games in which players cooperate to help each other score points or win prizes are described. In a game, players are grouped into rooms where they can collect puzzle pieces using a random selection technique, such as a spinner. The spinner can provide puzzle pieces, points, additional spins, and/or loss of spins. The player can position a puzzle piece on a game board, offer to give a puzzle piece to another player in the room, and/or offer to trade a puzzle piece for another player's puzzle piece. The other players can accept or reject proposed gifts and/or trades. The player can collect and use the puzzle pieces to complete the puzzle. The player can earn points for completing the puzzle, which may be used to win a prize.

Abstract: A method for simulating large circuits in full-scale. To enhance the simulation efficiency, subcircuits are extracted from a circuit and thence a hierarchical structure is established using the extracted subcircuits. Subsequently, the circuit is partitioned and a current-voltage table for each subcircuit is dynamically generated. A transient analysis of the circuit is preformed at each incremental time step and a recursive latency check is preformed from the top to the bottom level of the hierarchical structure to determine the active part of the circuit. Using the current-voltage curves, a portion of the conductance matrix corresponding to the active part is rebuild at each incremental time step, which significantly reduces the simulation time.
