摘要： To provide a deformable sensor system, which makes it possible to obtain a pressure distribution with a much higher accuracy, while reducing the number of electrodes.A deformable sensor 12 comprises an elastic material whose electric resistivity, when all types of elastic deformations are caused therein respectively, increases monotonically as an elastic deformation variation in each of the elastic deformations increases. Based on a voltage being detected by means of a detecting unit 22, the deformable sensor 12's electric-resistivity variation δρ(x, y), which minimizes an evaluation Function J of Equation (1) while satisfying a condition of Equation (2), is computed at an electric-resistivity variation computing unit 25 using such a technology as “EIT” that is based on an inverse-problem theory. At an external-force position computing unit 26, a position in a pressure-receiving surface 12a, position which receives an external force, is computed based on the computed electric-resistivity variation δρ(x, y). J=∥δV(m,n)−Sm,n,x,y·δρ(x,y)∥2  (1) However, δρ(x,y)≧0  (2)

摘要： A vibration restraining apparatus for vehicle of the present invention is comprised of a housing formed by a rigid material and having an inner space, and fixed to a vibration transmitting member; a filled member sealed in the inner space of said housing in a non-adhered state with leaving a gap with respect to a vibrating direction of said housing, and formed by an elastic body at least at a surface thereof. When the housing resonates by vibration transmitted from the vibration transmitting member, the filled member contacts inner surface parts located at both sides of the housing in a vibrating direction thereof to exercise a damping character due to an energy loss caused by a sliding friction and a collision. Thus, a large damping character occurs inside of the housing to reduce vibration of the housing effectively. As a result, vibration of the vibration transmitting member is effectively reduced. The vibration restraining apparatus for vehicle of the present invention can be lightened in weight, does not have a temperature dependency, and can exercise the vibration restraining effect for plural resonances having different frequencies.
