摘要:
The invention relates to a motor vehicle comprising a compressed-air braking system. Said vehicle has two braking cylinders, which can be impinged by compressed-air from a compressed-air reserve by means of a manually actuated brake valve. The braking cylinders have ABS pressure-control valves, which can be selectively impinged by compressed air from the compressed-air reserve, using a slip control valve. A stability sensor detects a motor vehicle position and a control device selectively supplies the slip control valve and the ABS pressure-control valves with compressed air, in accordance with the signals of the stability sensor.

A service brake device of a vehicle, including at least one ABS pressure control valve which is controlled for slip-regulated braking by an electronic control unit, has at least one inlet valve and one outlet valve and is arranged upstream of a pressure medium actuated brake cylinder, a pressure medium line which supplies the ABS pressure control valve with pressure medium and into which a pressure controlled by a valve device arranged upstream of the ABS pressure control valve is feedable, wherein the valve device feeds a pressure derived from a reservoir pressure of a pressure medium reservoir into the pressure medium line as a function of an activation by the electronic control unit.

A system for controlling at least one of the slip threshold and the time period for an extended wheel slippage for a vehicle that is operating in the off-road ABS mode. When driving in a curve pattern and/or at high speeds, the individual wheel speeds are controlled with a lower slip threshold and/or shorter time period for the extended wheel slippage than when driving straight ahead and/or at a lower vehicle speed. Control of the brakes is accomplished by (i) controlling at least one of the individual wheel slip threshold and the time period for an extended wheel slippage based on the actual vehicle speed; (ii) controlling at least one of the individual wheel slip threshold and the time period for an extended wheel slippage depending on actual lateral acceleration; (iii) using a lateral acceleration sensor to measure actual lateral acceleration; (iv) measuring the actual steering angle with a sensor and controlling the wheel speed cycles in conjunction with the actual vehicle speed; (v) using a yaw rate sensor to determine at least one of the deepness and the time period of the wheel slippage; (vi) controlling the speed of the wheels on either side of the vehicle with different slip thresholds and/or different time periods for the slippage extension; (vii) controlling at least one of the individual wheel slip threshold and the time period for an extended wheel slippage depending on the wheel speed difference of a non-driven axle; and/or (viii) deactivating the off-road mode automatically when the vehicle reaches a predetermined speed.

Gas-tight container featuring an outer shell of metal or metal and plastic or metal and cellulose-containing material, a base, a lid and at least one side-wall. The container may be e.g. a can with, as viewed in plan view, a polygonal, round or oval cross-section. The base or part of the base of the gas-tight container exhibits a region which may be made to bulge and which is surrounded by an endless depression and, in the condition in which the can may be used, is in the form of a concave bulge. A container of this kind is such that one can readily recognize if the contents have suffered from spoiling or decomposition and, as a consequence, gas has been formed inside the container. If the pressure inside the container increases, the bulge is pushed outwards and, usefully, may form a convex bulge. If the bulge is pushed out by the increase in internal pressure, it projects beyond the outer limits of the container base rim, as a result of which the linear or ring-shaped contact the base rim makes with an underlying surface changes to two point contact and the container indicates a chemical or physical change by its instability on an underlying surface.

The invention concerns an interference fit comprising a carrier and at least one stepped bushing seated with an interference fit on the carrier. The stepped bushing is made by shaping a sheet metal and is characterized by a special wall thickness configuration. Through this wall thickness configuration, it becomes possible to assure that the stepped bushing conforms to close shape tolerances in the pressed-in state in regions of functional relevance.

A method and apparatus for calculating flow transparency values for voxels representing blood flow within an ultrasonic volume of data comprises identifying velocity values and variance values for voxels within a volume of data. Flow transparency values are calculated for the voxels based on a relationship between the variance value and the velocity value.
