A method for determining a cutting trajectory that enables a curve section of a lane to be cut by a vehicle. In the method, information about the curve section is received, and the curve section is divided into at least one curve segment having a segment length and a start curvature, the curve segment being a straight-line segment or a circular arc segment or a curve segment whose curvature is a function of an arc length of the curve segment. This is followed by determination of a cutting trajectory from the at least one curve segment, so that, at a specific point of the curve section, the cutting trajectory has a predetermined offset relative to a center of the lane.

The invention relates to a hybrid three-dimensional sensor array, in particular for measuring biological cell assemblies. The sensor array has a plurality of microstructured sensor plates, each having one carrier section on which a plurality of sensor needles are arranged in a comb-like manner, which carry a plurality of electrode surfaces. Furthermore, a plurality of spacer elements are provided, which are fastened between the sensor plates so that both the carrier sections and the sensor needles of adjacent sensor plates are at a distance from each other. The invention further relates to a measuring assembly for measuring electrical activities of biological cell assemblies using such a sensor array.

A folding box with a blister pack held therein is produced from a one-piece blank, having a first tab which starts integrally from a narrow side wall and in the use position inside the folding box rises obliquely inwards from this edge toward the opposite wall and is supported resiliently against the latter. A second tab is bent back from the support point of the first tab and in the use position comes to lie between the first wall and the first tab or the second wall, and in turn carries at its edge a locking tab which in the use position engages in a hinged fashion between two blister cavities or cavity rows arranged one behind the other in the insertion direction, and thereby secures the blister pack in locking fashion without the need for beads or other deformations that affect the surface on the folding box.

A decoupling element for a fuel injection device provides a low-noise construction. The fuel injection device has at least one fuel injection valve and a receiving bore in a cylinder head for the fuel injection valve as well as the decoupling element between a valve housing of the fuel injection valve and a wall of the receiving bore. The spring rigidity of the decoupling element is so low and the decoupling element is placed between the valve housing of the fuel injection valve and the wall of the receiving bore in such a way that the decoupling resonance is located in the frequency range below 2.5 kHz. The fuel injection device is particularly suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing spark-ignited internal combustion engine.

The fuel-injection device is characterized by an especially low-noise design. The fuel-injection device includes at least one fuel injector and a fuel rail having at least one pipe connection, the fuel injector being introduced into a receiving bore of the pipe connection, and the fuel rail having a discharge opening to supply fuel to the fuel injector. Provided between the fuel injector and the fuel rail is a pressure-wave guide connecting both, in such a way such that dynamic pressure fluctuations in the fuel injector are able to be routed largely past the volume of the receiving bore of the pipe connection. The fuel-injection device is especially suitable for the direct injection of fuel into a combustion chamber of a mixture-compressing internal combustion engine having external ignition, but it is also suitable for the injection of fuel into an intake manifold.

A vibrating plate comprises a vibration generator device, which can be controlled in such a manner that the direction of the action of force can be set at a number of locations, particularly in more than two locations. In addition, an advance adjusting device is provided for controlling the vibration generator device whereby the direction of the action of force is set in a position in which a maximum possible advance of the vibrating plate is reached. The direction of the action of force can be changed according to a change in the surroundings of the vibrating plate, particularly to the slope and/or the hardness of a subsoil to be compacted by a soil contact plate. Alternatively, the direction of the action of force can be changed according to the wishes of the operator.

The invention relates to an automatic belt tensioner comprising a basic part that is connected to a tensioning part so as to be rotatable about a common axis of rotation, a helical spring that is joined to the basic part and the tensioning part, and a wrapping bush which is wrapped at least in some areas with a radial enveloping force by means of the helical spring. According to the invention, the material of the wrapping bush contains reinforced plastic in order to ensure that the belt tensioner provides good damping and good cushioning properties if possible during the entire service life thereof while being universally usable and having a simple design.
摘要:
A fast light off flow-through ceramic substrate is provided that is particularly adapted for use as a catalytic converter. The substrate is formed from a body of ceramic material having axially opposing inlet and outlet ends for receiving and expelling the flow of automotive exhaust gas, respectively. The body contains a network of walls coated with a catalyst that define axially-oriented flow-through cell channels. The average thermal mass (ATM1) of a first axial region of the walls adjacent to the inlet end is at least 20% less than the average thermal mass (ATMTOT) of all of the walls. The lower average thermal mass of the walls in the first region advantageously shortens the light off time for the catalyst within the substrate to effectively neutralize automotive pollutants. The reduction of the average thermal mass in only the first axial region of the walls advantageously maintains the strength of the resulting body of ceramic material, and further increases the cool down time of the body.
