摘要:
An impact resistant tool or tool bit holder has an active end for driving a fastener and a shanking end for securing to a power tool. The active end includes a body with a bore to receive the shank and a pocket to receive a damping mechanism. The shank includes an end to engage the bore in the body, and a pocket to receive the damping mechanism. The shank is received in the bore in the body for limited rotation with respect to the body. A damping mechanism is positioned in the pockets to provide damping between the body and the shank during torque loading.

An outer-rearview-mirror unit for a motor vehicle comprises an electrical switching device with a number of positions, which controls electrical supply of a plurality of shape-memory wires that control oscillation of the reflecting plate of the mirror. The electrical switching device has a single control lever with a number of positions projecting from a support, which, in the mounted condition of the mirror, is in a position coinciding with that of the base of the mirror, on the inside of the passenger compartment of the motor vehicle.

An electrical energy generator device comprising an array of micro-fans each associated to a respective dynamo-electric generator by means of a respective connecting shaft, further comprises, for at least some of the micro-fans (3), a lug element (6) associated to the respective connecting shaft (4) which mechanically co-operates at each revolution with a piezoelectric element (7), for the production of additional electrical energy. In addition or instead of the aforesaid arrangement, it is possible to provide plates (10) made of piezoelectric material which vibrate in the flow of air that invests them, thereby producing electrical energy.

摘要:
A shape memory bistable actuator includes an element movable mounted on a fixed support structure, having an intermediate position of dead center and two end positions. Spring means tend to return the movable element towards either end positions, depending on that it is on either part with respect to the dead center position. Shape memory means are provided for causing a displacement of the movable element from either end positions, against the action of the spring means, at least until the dead center position is exceeded. After this exceeding, the activation of the shape memory means can be stopped, as the spring means provide to proceed the movable element toward the new desired working position, and to hold it in such a position, despite the shape memory means are deactivated.

A motor-vehicle dashboard incorporating an air distribution system that includes suitable means for controlling the deviation of airflow in the various ducts (3) associated with the outlet vents (2) on the dashboard, using the Coanda effect.
摘要:
A vehicle headlamp having two glass panes carrying an array of micro-lenses that can be moved relative to each other both along the optical axis of the headlamp and along a direction orthogonal to the optical axis. These movements are controlled via a number of shape memory actuators.
摘要:
A temperature-sensitive label is described. The temperature-sensitive label has a container provided with means for the application on an item to be monitored and housing a temperature-sensitive system made up of a filiform shape memory member. The filiform shape memory member is restrained to a filiform bias member provided with an engaging seat, and is introduced in such a way that in case of exposure to a temperature lower than a preset critical threshold temperature (Tc), the filiform shape memory member performs a phase transition, causing an irreversible disengagement condition visible through a transparent window.
