A combination starter-generator device for a work vehicle includes an electric machine and a bi-directional gear set. The gear set is configured to receive rotational input from the electric machine and from the engine and to couple the electric machine and the engine in a first power flow direction and a second power flow direction. In the first power flow direction the gear set effects a first gear ratio, and in the second power flow direction the gear set effects a second gear ratio. In the first power flow direction, the gear set receives input power from the electric machine in a first clock direction and outputs power to the engine in a second clock direction opposite the first clock direction. In the second power flow direction, input power from the engine is in the second clock direction and output power to the electric machine is in the second clock direction.

Apparatuses, systems, and methods of use for a generator is disclosed. In one embodiment, the generator comprises a stator and a rotor and a first plurality of magnets coupled to the rotor and a second plurality of magnets coupled to the stator. An external magnetic housing may be coupled to an input shaft of the generator or surround the generator itself. A first layer of magnets produce a rotating magnetic field and a second layer of magnets create a static magnetic field, whether such magnets are in the generator itself or within an external magnetic housing. The disclosed generator increases the mechanical power inputted into the generator, which then produces an increased output of the generator.

A system for fixing and/or emergency opening of a leaf of a door, a window or other closure comprises a drive having at least one mechanical energy storage device, at least one electric motor having a motor shaft operatively connected to the leaf, and control electronics for controlling the electric motor. The electric motor can be actuated by the control electronics both for damping of the leaf movements and for fixing of the leaf against a force of the mechanical storage device and/or for electric motor-driven emergency opening of the leaf.

This application concerns embodiments of a low cost magnetically geared lead screw (MGLS). In some embodiments, a MGLS system comprises at least an outer cylinder, an inner rotor, and a translator sandwiched between the outer cylinder and the inner rotor. In various embodiments, the MGLS overcomes some of the disadvantages of other systems by skewing magnetic pole pairs on either or both of the outer cylinder or the inner rotor instead of skewing magnetic portions of the translator. By skewing the pole pairs, the translator placed between the outer and inner cylinder is generally not required to contain any magnetic material (such as permanent magnets or magnetic rings, rare earth elements, etc.), which may otherwise cause the translator to become costly and/or heavy, or to exhibit any other number of deficiencies.

A system and method that pertain to a rotating vehicle display unit that can automatically or manually rotate between landscape and portrait orientations, depending on the particular display format or media being shown to the vehicle occupants. The rotating vehicle display unit uses an electro-mechanical rotating and locking mechanism with smart fluid, such as magnetorheological fluid (MR), to facilitate easy and precise rotational movement between different display orientations. The rotating vehicle display unit may be coupled to a corresponding human-machine interface (HMI) that responds to the different display orientations and helps facilitate easy transition from one orientation to another in order to optimize the particular display format or media being shown at that time.
