摘要:
A shape-memory actuator device comprises means for interrupting electrical supply to a shape-memory element (2) when the axial load applied to said element exceeds a predetermined threshold value.
摘要:
A method and a system for controlling a plurality of shape-memory actuators (1), for instance installed on board a motor vehicle, control the electric supply current of each shape-memory elements (1) as a function of one or more parameters referring to environmental conditions, such as environment temperature and temperature of memory-shape actuator, of available supply voltage for motor vehicle battery, of previous actuations, or of previous activation requests of shape-memory actuators (1).
摘要:
A motor-vehicle bumper is provided with a number of piezoelectric elements (2, 3, 200, 300) which are connected to an electronic control unit (400) programmed to operate one or more of the piezoelectric elements such that each of them, or one or more groups of them, fulfil different functions in different conditions of operation of the motor-vehicle.
