Abstract: A gear shift device for a mobility machine has a plurality of gears between a first gear referred to as gear No. 1 and a top gear. The gear shift device includes a series of input pinions arranged so as to turn freely around a selection shaft with an axis X2, said selection shaft accommodating a worm screw and a shuttle. The gear shift device also includes a series of output pinions with an axis X3 that rotate conjointly with a hollow shaft a gear shift actuator arranged so as to displace the shuttle along the worm screw between a plurality of positions and to engage a selected gear. A mobility machine can include the gear shift device.

Abstract: The invention relates to a gear shift device for a mobility vehicle, comprising: —a selection shaft in which a shuttle and a worm are arranged, —at least two input pinions arranged to rotate freely about the selection shaft, —at least two output pinions coupled in rotation with a hollow shaft, —a gear shift actuator arranged to move the shuttle along the worm between at least two positions, and to engage a selected gear ratio, —at least two pawls arranged on the selection shaft, each pawl being associated with a lifting device for lifting the pawl via the shuttle, and to engage the gear ratio selected via the input and output pinions, the device comprising a radial blocking system, which is formed in one piece, for keeping all the pawls in place on the selection shaft.

Abstract: Systems, methods and computer program products that provide a framework for the creation, editing, manipulation and use of model-based, multidimensional analysis services (MAS) cubes are disclosed. A method of generating a model-based MAS cube comprises creating a data source comprising a data warehouse in the memory via the processor, creating a data source view providing a dimension, a fact and an outrigger from the created data source, and creating the MAS cube comprising at least one measure group. A key performance indicator (KPI) may be calculated from the MAS cube as a scorecard of a display associated with the processor. A user of the model-based MAS cube may create a new cube by targeting a set of facts and adding dimensions to the facts.

Abstract: The invention concerns a method for controlling the opening of an internal combustion engine throttle valve body assembly, characterized in that it includes the following steps: specifically mapping the engine, limiting the opening angle of the throttle valve body assembly, and defining particular operating points requiring replacement of the usual mapping by the specific mapping.
