Abstract: A drive train for a wind-up injection device is described. The drive train includes a torsional energy storage adapted to be loaded or unloaded by a rotatable element, a rotatable user handle, a rotationally driveable expelling mechanism adapted to expel the liquid drug, and a clutch element coupled with the torsional energy storage via the rotatable element and including a ratchet for maintaining the rotatable element at one of a number of discrete angular positions against the torque of the torsional energy storage. The clutch element is adapted to transmit the torque from the user handle to the torsional energy storage, or alternatively from the torsional energy storage to the expelling mechanism. The ratchet is switchable from one position to an adjacent position by a torque transmitted from the user handle to the torsional energy storage. The drive train is adapted to dampen torque peaks visco-elastically and/or visco-frictionally.

Abstract: Aircraft fly-by-wire systems and related vehicle electrical systems are provided. A vehicle electrical system includes a bus arrangement having a plurality of buses, a first control module coupled to a first subset of the buses, a second control module coupled to a second subset of the buses, and a third control module coupled to a third subset of the buses. The first subset includes a first bus, a second bus, a third bus, and a fourth bus, the second subset includes the third bus, the fourth bus, a fifth bus, and a sixth bus, and the third subset includes the first bus, the second bus, the fifth bus and the sixth bus.
