Abstract: A device made of an elastomeric material that dampens vibrations caused by cooling fans. The device attaches to both faces of a cooling fan and fully decouples the fan from the enclosure. This reduces or eliminates auditory vibrations transmitted through the thermoplastic fan frame and fan mounting screws. The device achieves this decoupling through three different methods. Firstly, a large flat elastomer surface is placed between the cooling fan face and the electronic enclosure. Secondly, elastomeric protrusions prevent fan mounting screws from touching the cooling fan frame. Thirdly, a thin elastomeric wall extends around the outside of the cooling fan frame and prevents contact between adjacent cooling fans. Together, these features prevent auditory vibration transmission into the electronic enclosure. The flat elastomeric surface also creates an airtight seal between the cooling fan and enclosure. This seal prevents the formation of small air gaps which can result in an audible airflow leakage.

Abstract: A Flexray gateway comprising a first and a second bus interface for connecting a first and a second Flexray bus, wherein the Flexray gateway comprises coupling means for coupling a first and a second Flexray bus and for transmitting bus messages between the first and the second Flexray bus, wherein the Flexray gateway comprises a Flexray controller with a first and a second channel interface for transmitting and receiving bus messages of a first and a second channel type of a Flexray bus.

Abstract: A test device and a test method, the test device comprising a bus controller for the transmission and reception of bus messages, the bus controller having a message memory for offering transmission data for bus messages, the message memory having a memory capacity for a bus message sequence with bus messages to be transmitted within a single transmission cycle or a transmission cycle sequence. The test device includes an intermediate memory for the storage of transmission data for bus messages with a larger storage capacity than the message memory. The test device furthermore comprises a transmission preparing means for reading transmission data from the intermediate memory and for writing, in advance of reading of the bus controller, to the message memory of the bus controller so that the bus message sequence is expanded by additional bus messages which are transmitted by the bus controller within the transmission cycle or the transmission cycle sequence on the motor vehicle bus.
