A call path identifier is maintained which is permuted in response to a calling instruction for calling a target function, based on a function return address. The call path identifier is used as a modifier value for authentication code generating and checking instructions for generating and checking authentication codes associated with source values. In response to the authentication code checking instruction, if an expected authentication code mismatches a previously generated authentication code for a source value then an error handling response is triggered. This is useful for preventing attacks where address pointers which are valid in one part of the code are attempted to be reused in other parts of code.

A dispenser for flowable media is provided, which operates in user-independent manner with respect to the pressure buildup and dosage quantity. On pressing on an operating head (35) a piston rod (29) is forced into a pump cylinder.

A relatively constant pressure can be obtained over the entire discharge phase through the pretension of spring (42).

Configuration spaces facilitate the useful presentation of data, particularly configuration data used for representing configured products. Products include features and common features can be grouped by families. For example, an automobile can include a transmission family. The transmission family could include features such as automatic transmission and 4-speed manual transmission. Configuration spaces can be achieved by consolidating selected data without loosing useful information. The degree of consolidation achieved can be significant enough to permit display of data using conventional display technology. Configuration spaces break down the “universe” of possible configurations into constituent spaces defined by groups of rules for a selected feature. Common dependencies between the selected feature and related features can be consolidated to produce a more minimal form of the data used for representing the selected features and related features. Configuration spaces can provide a useful graphical view of the breakdown of all rules written for a single feature or multiple features. The data present in this view can be analyzed to, for example, study the dependency paths of an existing configuration and better understand the impact of revising configuration relationships. Thus, configuration spaces aid in the creation and modification of configuration models.

Systems and methods of predicting sheet metal forming failure using numerical simulations (e.g., finite element analysis) are disclosed. A FEA model is defined for a particular sheet metal forming process. Blank sheet metal is modeled with a plurality of shell elements. Additionally, a deformation path-dependent forming limit diagram (FLD) is converted to a path-independent FLD. A time-marching simulation of the sheet metal forming process is conducted using the FEA model. At each solution cycle, equivalent strain at each integration point of shell element is checked against the corresponding forming limit strain value of the path-independent FLD. The ratio of the equivalent strain and the forming limit strain is defined as formability index. A time history of the formability index of each shell element is saved into a file and displayed to a monitor upon user's instructions. When a particular element's formability index reaches one or higher, a localized necking is predicted.

A method for determining a torque characteristic of a friction clutch located in a drive train of a motor vehicle in the force flow between a drive engine and a transmission and which is closed in its rest position. At least two marker points of a regulating-path-dependent torque characteristic are determined, one of which is determined at a slipping limit of the clutch. To enhance determination of the torque characteristic, a first marker point is determined with the clutch engaged, the transmission in neutral and the engine running, by slowly disengaging the clutch until a reduction in the speed of the transmission input shaft relative to the engine speed is detected. A corresponding pair of values of this marker point with the known braking torque of the input shaft and the set position are used for adapting an existing characteristic.

The apparatus according to the invention comprises an object lens which can operate in at least two different measuring modes. In a first, interference mode a workpiece is measured by means of interference optometry. In a second, imaging measuring mode an optical image is produced, for example, on a camera-like detector array and may be applied to an image processing routine. Switching between the two measuring modes is performed by the type of illumination of the object lens and an element which is disposed preferably in the reference beam path of an interferometer and which activates or deactivates the reference beam path dependent on the spectral composition of the utilized light. In this manner a simple and rapid changeover between the two measuring modes is provided, without the need for replacing or even for moving the object lens. Apart from the rapidity of changeover, a good correlation is achieved between the measuring data which are yielded by the interferometry and by the image processing and which are obtained in one and the same reference coordinate system.
