Abstract: An electric brake system is proposed which includes an electric linear motion actuator and can generate the required braking force with high accuracy. A load sensor (30) is provided in a motion converting mechanism of the actuator which converts the rotary motion of a rotary shaft (4) to which the rotation of an electric motor (2) is transmitted to linear motion of an outer ring member (5) as an output member. The load sensor (30) detects the pushing force with which the outer ring member (5) linearly drives a driven member. With this arrangement, if the driven member is a braking member of an electric brake system, it is possible to directly detect the braking force applied by the driven member and thus to accurately generate the required braking force.

Abstract: A structure for bending transversal elastic waves around a zone to isolate of a plate, has an anisotropic Young's modulus and/or a heterogeneous mass density. The wavelengths of the elastic waves to bend are large with respect to the thickness of the plate and small with respect to the other dimensions of the plate. The structure is made by defining a meshing of a peripheral zone surrounding the zone to isolate; dividing the peripheral zone into several elementary rings and several elementary angular sectors; and forming, in each mesh delimited by an elementary angular sector and an elementary ring, a structural element in a material having a Young's modulus and/or a mass density different than those of the material forming the plate, the dimensions of the meshes and of the structural elements in the plane of the plate being less than half the wavelengths of the elastic waves to bend.
