Abstract
The invention relates to a hybrid drive transmission unit for a vehicle, comprising an internal combustion engine (12) and an electric motor (14) for the drive part, said unit being provided with a power-split transmission (20) with sub-transmissions (22, 24) and a torsion-damping unit with a gyrating mass, interconnected between the internal combustion engine (12) and the power-split transmission (20), and a clutch (38) interconnected between the internal combustion engine (12) and the torsion-damping unit (40), by which means the internal combustion engine (12) can be activated, switching from the electromotive operating mode. The invention also relates to a corresponding method.

Abstract
A drive system for a hybrid vehicle and a method of operation of the drive system are provided. The drive system includes an internal combustion engine having a shaft, a vehicle transmission having a transmission input shaft and an output shaft, a transmission clutch between the transmission input and output shafts, an inertia-mass drive unit arranged between the internal combustion engine shaft and the transmission input shaft, a first clutch between the internal combustion engine shaft and inertia-mass drive unit and a second clutch between the inertia-mass drive unit and the transmission input shaft; and an electrical machine torque-transmittingly connected to the transmission input shaft. The inertia- mass drive unit may include rotational oscillation reduction device. Operation of the first, second and transmission clutches in coordination with electric motor and engine operation provides multiple operating modes while minimizing operator disturbance during transitions between engine deactivated and activated states.

Abstract
The invention relates to a mixture, which is liquid at room temperature and which is composed of two or more compounds, which are constructed exclusively of the elements carbon and hydrogen and, in individual known compositions, form a synthetic substance mix that can be used as a heat-transfer liquid. The mixture is characterized in that the mixture contains at least one compound having at least two non-condensed, non-pi-conjugated aromatic units and is used in catalytic methods to bind hydrogen to or release hydrogen from the mixture.

Abstract
In a windshield device for a motorcycle, including a front cowl for covering a vehicle body on the front side, and a windscreen disposed at an upper part of the front cowl so as to be vertically movable, wherein an air introducing port for introducing air from the front side is formed between a lower part of the windscreen and a front surface of the front cowl, to control the flow of the air introduced into the air introducing port and efficiently to make the air flow along the rear surface of the windscreen, irrespectively of the moved position of the windscreen. An air guide for guiding the air introduced through the air introducing port to make the air flow rearwards along the rear surface of the windscreen is provided in the state of being fixed to the rear surface of the windscreen.

Abstract
The invention relates to a system and method for wireless diagnosis, elimination of a defect, a servicing or preparation of a servicing of a motor vehicle. A checking device is provided which checks whether the vehicle has a technical defect, whether a vehicle servicing should be carried out or whether the driver is requesting assistance. A status determining device determines which electrical or electronic components, hardware, assigned software versions are present in the vehicle, defect has occurred during the operation of the vehicle and was stored in the vehicle in the form of defect data, or which vehicle servicing should be carried out and which corresponding servicing data were stored in the vehicle. Only vehicle driver is enabled to clear establishment a telecommunication connection for transmission of data between the vehicle and a service facility.
