Abstract: A system for operator interface processing for collaboration with a trusted circle of project personnel is disclosed. The system includes a project manager system that selects user interface controls for a project manager and to generate the project manager user interface controls at a main menu of a project manager operator interface. A project service provider system selects user interface controls for a project service provider to generate the project service provider user interface controls at a main menu of a project service provider operator interface. A project personnel system selects user interface controls for project personnel and to generate the project personnel user interface controls at a main menu of a project personnel operator interface. The project manager user interface controls, the project service provider user interface controls and the project personnel user interface controls are different from each other.

Abstract: A system for operator interface processing for project-related information including a project personnel operator interface operating on a processor and configured to select a communications channel from a plurality of communications channels and to configure the communications channel as a preferred communications channel. A project manager operator interface operating on the processor and configured to receive the selected communications channel and to store profile data associated with the selected communications channel. A project service provider operator interface operating on the processor and configured to provide project data to the project personnel operator interface using the selected communications channel.

Abstract: A differential for motor vehicles installed between two half-shafts on which two drive wheels are keyed includes a box driven by the engine by a connecting element which causes it to rotate about axes of the half-shafts, on free ends of the latter there being keyed two bevel gears housed inside the box, the differential and the half-shafts being contained inside a casing. Each of the flanges through which the half-shafts penetrate into the box has a cylindrical extension outwards, with grooves which are complementary with respect to other grooves formed on the surface of a coaxial cavity formed in a sleeve slidable coaxially on each half-shaft and rotationally locked thereto, mounted inside the casing and provided with an element which causes it to slide in the two directions causing engagement between the grooves or disengagement thereof, locking together the box and the half-shafts or performing disengagement thereof.
