Abstract: In a method for operating a motor vehicle, the actual distance of the vehicle that is to be operated from a vehicle driving in front of the vehicle that is to be operated is detected, and the speed of the vehicle that is to be operated is influenced automatically such that a predetermined setpoint distance is maintained. Accordingly, the distance of the vehicle that is to be operated from a vehicle driving behind the vehicle that is to be operated is additionally detected. When the distance of the vehicle that is to be operated from the vehicle driving behind the vehicle that is to be operated drops below a specific limit value, the predetermined setpoint distance of the vehicle that is to be operated from the vehicle driving in front of the vehicle that is to be operated is automatically increased or the speed of the vehicle that is to be operated is automatically influenced such that the actual distance is increased in deviation from the predetermined setpoint distance.

Abstract: The present invention relates to an expandable semi-compliant device that may be used for the treatment of diseased or injured bone tissues, and a method of using the same. The semi-compliant device is inserted into the interior space of a cancellous bone tissue, and is filled with a suitable material to provide internal structural support to the bone. The semi-compliant device may also act as a carrier for medicinal, radiological, or thermal treatments of the diseased bone.

Abstract: In an arrangement for the control of the power transmission of a four-wheel drive vehicle, a main driving axle is driven directly and an auxiliary driving axle is driven via a continuously controllable longitudinal clutch by an internal combustion engine via a clutch-transmission unit. From a desired performance and the speed of the vehicle, a desired traction force of all the wheels is determined. From this desired traction force, and by a distribution factor that is dependent on operating driving parameters, the control quantity is obtained for the control of the longitudinal clutch. In addition, the longitudinal clutch can be controlled alone or in combination with the control quantity by an additional control quantity obtained by squaring of a speed difference at the longitudinal clutch.
