The present invention relates to linear actuators comprising an electrically-controlled shape memory alloy coil spring () suitable to provide linear displacements in valves, switches, lock systems and provided with a crimped terminal at each extremity, each of said crimped terminals comprising a crimping component () and an engaging member () suitable to mount the spring () into the linear actuator. The invention further discloses the use of said spring () with particular geometrical characteristics and crimping system assuring the maximization of the available stroke and fatigue life, structural simplicity, low electrical power requirements and thermal inertia, small size.

A temperature-sensitive label is described. The temperature-sensitive label has a temperature-sensitive system having a filiform shape memory member that has a first end portion having a terminal part fixedly secured to a first contact member, a second end portion having a terminal part restrained by a second contact member in a non-permanent way, and a central curved portion. The central curved portion is in the martensitic phase while the first and second portions are in the austenitic phase at a same environmental temperature above a critical threshold temperature to be monitored by the label such that in case of exposure to a temperature lower than the preset critical threshold temperature the end portions of the filiform shape member perform a phase transition, from austenitic phase to martensitic phase, which causes its irreversible disengagement from the restraint formed by the second contact member. The disengagement condition is optionally visible, for example, through a transparent window and/or monitored by an RFID system.

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.
