Power transmission unit

A power transmission unit in which an oil pump is arranged without extending a shaft length. In the power transmission unit, an input shaft, a first rotary machine, a differential mechanism, and an output shaft are arranged coaxially. The power transmission unit comprise: a first clutch that engages a first movable member connected to an input element of the differential mechanism with a first engagement section formed on another rotary element; a second clutch that engages a second movable member connected to the output element of the differential mechanism with a second engagement section formed on another rotary element; a drive gear mounted on the input element; a driven gear meshed with the drive gear; and an oil pump connected to the driven gear.

Electrified military vehicle

A military vehicle includes a chassis, a front end accessory drive (FEAD), and circuitry. The chassis includes an engine and an integrated motor generator (IMG). The FEAD includes multiple accessories and an electric motor-generator. The circuitry is configured to operate the military vehicle according to different modes. The circuitry is configured to receive a user input indicating a selected mode of the modes, and operate the chassis and the FEAD of the military vehicle according to the selected mode. The modes include an engine mode and an electric mode. In the engine mode, the engine drives the FEAD and the tractive elements of the military vehicle through the IMG for transportation. In the electric mode, the engine is shut off to reduce a sound output of the military vehicle and the IMG drives the tractive elements of the military vehicle for transportation and the electric motor-generator drives the FEAD.

Entitlement system

In an embodiment, a central repository of rights may be implemented, and accessing entities (e.g. clients) and entities for which access is controlled (e.g. files, servers, etc.) may rely on the central repository. The rights may vary on a client-by-client basis. In an embodiment, the rights may be managed as a value that is interpreted by the access-controlled entity. Accordingly, the definition of access rights may vary based on the entity. In an embodiment, visibility to the access rights may be limited. For example, the central repository may provide a handle that is associated with the access rights, but the access rights themselves may not be provided. When an accessing entity attempts to access the access-controlled entity, the handle may be used to identify the access rights. The handle may be presented to the central repository by the access-controlled entity to confirm access rights.
