Abstract: A downhole device configured to be inserted into a borehole includes a device body having an outer surface and a recess formed in the outer surface, a cover covering the recess to form a first cavity, and a shock-absorber configured to support an electrical module within the first cavity, the shock-absorber disposed between a base of the first cavity and the cover opposite the base. The downhole device also includes a vibration-damping layer disposed between the base of the first cavity and the cover, the vibration-damping layer configured to dampen vibration of the electrical module.

Abstract: A downhole device configured to be inserted into a borehole includes a device body having an outer surface and a recess formed in the outer surface and a cover covering the recess to form a first cavity, the cover forming a fluid-tight seal with the device body. The device includes at least one shock-absorber configured to support an electrical module within the first cavity, the at least one shock-absorber extending between a base of the cavity and an inner surface of the cover opposite the base. The device also includes a vibration-damping layer located on at least one of the base of the cavity and the inner surface of the cover, the vibration-damping layer configured to be in contact with a surface of the electrical module to dampen vibration of the electrical module.

Abstract: A front hood is provided for a motor vehicle that includes, but is not limited to damping element of plastic arranged between a top structure and a bottom structure. The damping element is glued to the top structure and the bottom structure. In the event of a head impact on the front hood the deformation of the top structure is retarded by the damping element. The damping element in the process supports itself on the bottom structure.

Abstract: A pneumatic actuator is provided for an active hood and includes a cylinder and a piston, which is movable in the cylinder between a lower terminal position, in which the volume of a chamber delimited by piston and cylinder, which may be impinged using compressed gas, is minimal, and an upper terminal position, in which the volume of the chamber is maximal. The piston is lockable in the lower terminal position by a detent body engaging in first recesses of the cylinder and the piston. A slider is displaceable by impingement using the compressed gas out of an idle position, in which it fixes the detent body in the first recesses, into a triggering position, in which a second recess of the slider overlaps with one of the first recesses and is capable, together with a single one of the first recesses of accommodating the detent body.

Abstract: A pyrotechnic actuator is provided for an active hood that encompasses an installation site for a gas generator, a cylinder incorporating a moving piston and a compressed gas line that joins the installation site with the cylinder. A filter body for trapping particles from the gas stream of the gas generator is arranged on the compressed gas line.

Abstract: A body for a motor vehicle includes, but is not limited to a supporting structure, a hood, which is hinged to the supporting structure and includes, but is not limited to a framework and an outer skin, and at least one compressible support disposed between the framework of the hood and the supporting structure. A contact surface opposite the support on the hood side is connected to the outer skin by a stiffening element extending through a cavity of the framework.
