At least one Helmholtz damper is arranged at a combustion chamber for a gas turbine in order to damp thermoacoustic oscillations; the damping volume of this Helmholtz damper is in communication with the combustion chamber via a connecting passage. Optimum damping is achieved in a simple way by virtue of the Helmholtz damper being designed in such a manner that its damping frequency is adjustable.

Methods and systems are provided for flowing crankcase gases through an aspirator arranged in a PCV line. The aspirator regulates PCV flow, and may also generate vacuum depending on a position of a pintle extendable across a horizontal passage of the aspirator. When regulating PCV flow and not generating vacuum, the aspirator is fully closed and crankcase gases in the horizontal passage are metered through an orifice in the pintle. When generating vacuum, the aspirator is at least partially opened and PCV flow through the horizontal passage generates vacuum at a vacuum port of the aspirator.

A dielectric elastomer has a film that contains a fluorinated silicone elastomer and has two faces. A coating of a stretchable electrode material is applied to each one of the two faces. The fluorinated silicone elastomer has a modulus of elasticity of maximally 450 kPa. The fluorinated silicone elastomer is a three-dimensionally crosslinked, fluorinated, alkyl group-containing polysiloxane in combination with a fluorinated silicone oil. Alternatively, or in addition, the fluorinated silicone elastomer is a three-dimensional wide-mesh crosslinked, fluorinated, alkyl-group containing polysiloxane whose wide mesh property has been effected by a chain length extension by addition of a chain-shaped silicone molecule containing two Si—H groups to an alkenyl group-containing polysiloxane molecule.

A method and to a control device for controlling a haptic accelerator pedal in a motor vehicle includes displacing a pedal lever in an actuation direction between a rest position and a maximally actuated position. The pedal lever is configured to be excited by an actuator by exerting a counter force against the actuation direction to generate a haptically perceivable signal. A current position of the pedal lever relative to a current position of the actuator is determined outside the phases for generating the haptically perceivable signal, and the actuator is subsequently controlled in such a manner that the actuator actively follows a change in the determined position of the pedal lever. The positional control is configured to prevent interfering influences on the pedal lever by the actuator.

A safety device for a battery having battery cells that are configured to connect to poles of the battery via charging and isolating devices includes a discharge device. The discharge device is configured to connect in parallel to the battery cells. The discharge circuit can include at least one discharge resistor and an electronic valve. The electronic valve is configured to switch on and off. The discharge circuit can be configured to activate with a battery management system.

An improved method and a cassette assembly for protecting electronic components, comprising of a housing that encloses the electronic components disposed over an insulator. The housing also encases a scissor jack component that can move from a first to a second position to enable actuation and unmating of the cassette assembly, such as to a next level of packaging. The housing has an overhang design, having complementary upper openings and lower cable shroud areas for supporting cable connections and for providing heat dissipation relief and EMC containment. Alternate designs provide for other components such as a honey comb screen and an EMC gasket to further enable EMC containment. In addition, other components such as an actuation trap door, a retention feature and card support members or support struts can be added to the design to enable better actuation and provide for an improved structural rigidity.

A vehicle crane having a hydropneumatic suspension and a braking system including wheel brakes and a first braking circuit assigned to the wheel brakes of at least one vehicle axle and a second braking circuit assigned to the wheel brakes of at least one other vehicle axle. In order to adapt the actuation of the braking system to the weight state, the hydropneumatic suspension is coupled to an automatically load-dependent braking force regulator that is operatively connected to one of the braking circuits or to one of their braking circuit sections such that, on the basis of a weight state signal of the vehicle crane generated from the hydropneumatic suspension, a braking pressure generated inside the braking circuit or braking circuit section coupled to the automatically load-dependent braking force regulator, can be varied with respect to a braking pressure generated simultaneously inside the other braking circuit or braking circuit section.

A vehicle braking apparatus that can exert high braking performance during vehicle braking is implemented by a control mode that can be realized in a braking apparatus (10) of usual hardware. In controlling the braking apparatus (10) of a vehicle, a climb rate of a wheel cylinder braking oil pressure (Pw) is decreased smaller than a climb rate corresponding to a climb rate of a master cylinder oil pressure (Pm) from a time point at which the wheel cylinder braking oil pressure (Pw) reaches a predetermined threshold value. The time point at which the wheel cylinder braking oil pressure (Pw) reaches the predetermined threshold value (P3) is estimated based on the climb process of the master cylinder oil pressure (Pm) or directly detected.
