Abstract: A spring-damper system includes at least a differential cylinder (4), a hydraulic accumulator (26) and a control valve device (1, 2). By at least one motor-pump unit (22), pressure fluid can be supplied to the annular end (6) or both the annular end (6) and the piston end (8) of the differential cylinder (4) in a closed circuit using the control valve device (1, 2).

Abstract: A method for starting-up a device with an embedded multimedia card (eMMC) is provided. The method comprises providing power to the device, putting the eMMC in a Fast-Boot modus, reading a bootloader from the eMMC into a RAM of the device, starting the bootloader in a CPU of the device, terminating the Fast-Boot modus, resetting the eMMC, putting the eMMC in the Fast-Boot modus initializing hardware by the bootloader, while reading an operating system into the RAM using DMA, and starting the operating system from the RAM by the bootloader is provided. A device comprising an embedded eMMC is also disclosed.

Abstract: A spring-damper system consisting of at Least a differential cylinder (4), a hydraulic accumulator (26) and a control valve device (1, 2), is characterized in that by means of at least one motor-pump unit (22) pressure fluid can be supplied to the annular end (6) or both the annular end (6) and the piston end (8) of the differential cylinder (4) in a dosed circuit using the control valve device (1, 2).

Abstract: In the case of a motor vehicle having a number of seats arranged in a common passenger compartment, in particular having seats in two or more rows one behind another, the invention makes provision for the arrangement of a passenger compartment communication system, at least one seat or one group of seats being assigned a microphone and another seat or another group of seats being assigned a speaker which is operatively connected to said microphone. This permits a conversation between the occupants in an unrestricted manner even when they remain in their desired sitting positions and speak comparatively quietly.
