Abstract: Actuator assemblies comprising a core made up of a shape memory alloy wire and a coating containing a distribution of Phase Changing Material (PCM) particles with a given weight ratio between said particles and said shape memory alloy wire, and active cloths incorporating one or more of said actuator assemblies.

Abstract: Methods and apparatuses for simulating an electromechanical object are described. An electromagnetic solver is invoked for an electromagnetic model of the object to generate an electromagnetic loss of the object an operating temperature. A temperature dependent electromagnetic loss of the object is determined based on the electromagnetic loss at the operating temperature. The temperature dependent electromagnetic loss varies according to a temperature of the object. A thermal solver is invoked for a thermal model of the object to estimate a temperature of the object based on the temperature dependent electromagnetic loss of the object and the operating temperature.

Abstract: Thermostatic shape memory alloy torsional actuator comprising a torsional shape memory alloy wire (1) connecting a stationary element (2) with a rotatable element (3) so as to move the latter between a rest position and an operating position, and a return element (11) acting on the rotatable element (3) so as to move the latter between said operating position and said rest position, and fluid control thermostatic valves comprising such torsional actuator.

Abstract: A lock for closing a door with respect to a frame. The lock includes a lock body mounted on the door and a striker mounted on the frame, or vice versa. The lock body includes a catch element mounted so as to rotate between a striker keep position and a striker release position; elastic means suitable for driving the catch element from the striker keep position to the striker release position; a lever suitable for moving between two positions, a closing position in which it maintains the catch element in the striker keep position and an opening position in which it is disengaged from the catch element; and a service actuator suitable for applying a force f on the lever so as to bring it from the closing position to the opening position. The lock body further includes an emergency SMA actuator suitable for applying a force on the lever so as to bring it from the closing position to the opening position.

Abstract: A process for manufacturing caps, such as helmets, of reinforced resin, the reinforcement of which is comprised of a tricot or net-like material. The process comprises shaping the textile reinforcement, made of a plurality of layers of two or more textile caps to conform to the male component of a mold having complementary male and female components, inserting the male part, with the textile reinforcement, into the complementary female part of the mold, imparting a controlled tension to said textile reinforcement and injecting resin, in a liquid state, into the mold to envelope said textile reinforcement, and allowing said resin to solidify to thus obtain the cap, the reinforcement of which is enveloped in the resin in a state of tension. An impact resistant resin structure in the form of a cap is provided by said process.
