Abstract:
A safety device for a motor vehicle includes a deformation element which is arranged between a bumper beam and a side rail and moves into the side rail in the event of an impact. The deformation element is configured in the form of an evertable tubular member having a side-rail-proximal rear end provided with an abutment ring. Operatively connected to the deformation element is an actuator which is provided to release a displacement of the deformation element into the side rail in a predefined speed range by liberating the abutment ring in relation to the side rail in a release position, and to block the displacement of the deformation element into the side rail, when the speed range is exceeded or a vehicle speed is below the speed range, by locking the abutment ring in relation to the side rail in an engagement position.

Abstract:
An apparatus for generating electrical power from the waste heat generated by an internal combustion engine includes a first pipe wall through which a heated medium flows, a thermoelectric generator disposed exteriorly to the inner pipe wall, and a second pipe wall disposed exteriorly to the thermoelectric generator. The first pipe wall and the second pipe wall form at least a partially double-walled pipe. The first pipe wall saves as a high-temperature source. The second pipe wall serves as a low-temperature source.
Abstract:
A heat exchanger includes a housing having first and second longitudinal housing walls disposed in opposite relationship, and plural cartridges which are made from extruded aluminum sections and have channels for flow of a first medium there through. The cartridges are received in the housing in alternating relationship in several rows to thereby define a multiple S-shaped curved flow path for flow of a second medium around the cartridges, with a first longitudinal side of each of the cartridges touching one of the first and second housing walls and with an opposite second longitudinal side thereof positioned at a distance to the other one of the first and second housing walls.
