Embodiments of the invention relate to systems and methods for multi-player gaming. Some embodiments relate to systems having an improved communications infrastructure and improved handheld game controllers, while other embodiments relate to improvements in handling large numbers of players in the multi-player game when played in a game arena with a single large display screen showing the multi-player game images. In one particular embodiment, a system is provided that has a game server controlling a display system to display the multi-player game on the large screen and a plurality of game controllers. Each game controller has a secondary display means for providing a secondary game display and input means for receiving player input. The system further comprises communication means for enabling communication between the game server and each of the plurality of game controllers. The plurality of game controllers are located in proximity to the large display screen such that it is visible to game players manipulating the game controllers while playing the multi-player game.

A transmission device capable of cooperating with a dual-power source and a driving method therefor, the transmission device includes a planetary gear assembly that is driven by the dual-power source; the planetary gear assembly comprises a sun gear, a rotating inner gear ring, and a planetary gear that is engaged between the sun gear and the rotating inner gear ring; the dual-power source comprises an input shaft, the input shaft being connected to the sun gear.

A shift control method for an automated manual transmission (AMT) of a vehicle includes: when a shift operation is started, a torque of the second motor is increased so that a change in an output torque of the output shaft due to a change in a torque of the first motor is minimized while the torque of the first motor is being decreased. According to the shift control method, the increased torque of the second motor is maintained to be constant while controlling transmission release, speed synchronization, and transmission coupling. After the control over the transmission coupling is completed, the torque of the second motor is controlled so that the output torque of the output shaft follows a predetermined target torque while the torque of the first motor is controlled to be increased.
