Abstract: In a method and a system for improving a user's experience with a graphical user interface corresponding to a gaming or simulation environment on an electronic device, the interface renders multiple graphical objects and user selectable options corresponding to the graphical object. The user selects one or more selectable option, and performs a touching or a swiping operation through multiple points on the display screen. The touching or swiping operation leads to deploying of multiple resources corresponding to the selected option, at different locations on the interface. For controlling the different deployed resources, the user can swipe through different regions of the display screen. The number of resources deployed at the different locations on the screen depends on certain parameters, including the pressure applied by the user on the screen. Results of the simulation can be employed to control real technical systems, for example for food production.

Abstract: Embodiments are directed to a selectable drive system that allows a rotor gearbox to send torque to a proprotor assembly and/or through a multiplier planetary gear set to a pylon-mounted ducted fan thrust unit. The rotor drive system may be a stop-fold system in which rotor blades can be folded when not rotating.

The multiplier planetary gear set increases the output RPM that is received from the rotor gearbox and that is applied to the thrust fan unit.
