Abstract: A tuned mass damper for damping airborne vibrations at one or more rail frequencies from a rail generated by movement of wheels over the rail. The tuned mass damper includes one or more damper elements including a damper element material, and a body element including a body material. The damper elements are at least partially embedded in the body element. The body element has inner and lower exterior surfaces formed to fit within first and second pockets on opposite first and second sides of the rail defined by a web portion and a foot. The damper element material and the body material are selected and formed so that the tuned mass damper vibrates in response to movement of the wheels over the rail at one or more damper frequencies that at least partially interferes with the rail frequencies.

Abstract: A device for non-contacting transmission of electrical signals between one part moving relative to another part has at least one strip conductor pair for symmetrical signal transmission attached on a first of the two parts, in which strip conductor pair the electrical signals are supplied from a transmission module for differential signal transmission. At least one reception element is attached on the other of the two parts, at a slight separation along at least one segment of the strip conductor pair, and is connected with a reception module. The strip conductor pair is provided with one or more components for reduction of a common mode signal component that arises therein due to the differential signals therein. Additionally or alternatively, compensation elements for adaptation of a time offset between signals on the output conductors are arranged in the output conductors of the transmission module that minimizes the common mode signal component.
