Abstract: A marine propulsion system having a simple configuration and high energy efficiency and a marine vessel having the same. A detonation device for generating a detonation wave and a detonation wave discharger for releasing a detonation wave generated in the detonation device into the water so as to propel the marine vessel. When a detonation wave generated in the detonation device is discharged into the water by the detonation wave discharger, the discharged detonation wave pushes against the water, so a thrust pushing against a hull is generated as a reaction to the pushing force. A large-scale mechanism such as a propulsion system using a mechanical drive mechanism such as a screw or a propulsion system for generating a high pressure gas by utilizing a compressor is not needed, so the configuration can be simplified. Further, the water is pushed away by the detonation wave, so turbulence becomes hard to occur in the water, and the loss of the energy due to turbulence can be greatly reduced.

A new movement parameter (V and ?) is determined using movement parameters having been previously determined (Vp and ?p) and the newly calculated movement parameter (V and ?). When the first object and the second object satisfy a predetermined positional relationship therebetween, the second object is moved and display-controlled based on the updated movement parameter.

Abstract: A game system includes plural game apparatuses, and the respective game apparatuses are communicably connected to one another. For example, when a communication game is interrupted, a player closes his/her own game apparatus. In such a case, prior to setting of a sleep mode, the game apparatus notifies all other game apparatuses of the interruption of the communication game, and then the game apparatus saves parameters necessary to execute a game main processing program to interrupt the execution of the game main processing program. When the other game apparatuses receive the notification on the interruption of the communication game, the other game apparatuses save the parameters to interrupt the execution of the game main processing program. In resuming the communication game, the respective game apparatuses read the saved parameters to resume the execution of the game main processing program.
