Abstract: A system for generating and synchronously executing a multiplayer scenario, in one of a virtual, mixed and augmented reality environment and having a visual programming module allowing generation and management of at least one of an asset of a scenario and a visual acyclic relation action graph defined by a plurality of nodes and a network module configured to connect a plurality of clients over a network for synchronized execution of the nodes of the acyclic relation action graph. The network module operates using a network protocol including an identity component including a unique asset identifier and an asset container for each asset of the scenario and being replicable on the plurality of clients; and a node component defining a unique node identifier and a node container for each node of the visual acyclic relation action graph and being replicable on the plurality of clients.

Abstract: A series-hybrid powertrain includes a range extender, a battery, an electric motor and a controller. The range extender may include an internal combustion engine and a generator. The powertrain has three modes of operation. In electric only mode, the battery powers the motor and the range extender is not allowed to operate. In forced charge mode, the range extender attempts to power the drive motor and also re-charge the battery if the battery is discharged to, or is found below, a specified charge. In hybrid mode, the range extender is operated by a controller that determines the output of the range extender in hybrid mode considering inputs that relate to the state of charge of the battery and the power consumption of the electric motor. Optionally, the controller uses fuzzy logic to determine the output of the range extender. The powertrain may be used in an industrial vehicle.

Abstract: The invention concerns a very high mechanical strength steel, whereof the chemical composition comprises in wt. %: 0.060%=C=0.250%; 0.400%=Mn=0.950%; Si=0.300%; Cr=0.300%; 0.100%=Mo=0.500%; 0.020%=AI=0.100%; P=0.100%; B=0.010%; Ti=0.050%, the rest being iron and impurities resulting from preparation. The invention also concerns a method for making a sheet of said steel coated with zinc or zinc alloy.

Abstract: An adjustable steering column for use with a personal watercraft. The adjustable steering column comprises a steering column base fixed to the watercraft, an upper steering column connected to the steering column base, the upper steering column being movable between a first position and second position, and an adjustment mechanism for moving the upper steering column between the first and second positions. Preferably, the adjustment mechanism includes a screw with a knob on one end and a ball joint on the other end. The adjustment screw is manually operable to pivot the upper steering column with respect to the steering column base.
