Abstract: A method for predicting a development over time of a system quantity (WP, 41, 42, 43, 44, 6) of a system (2), to which a number of system quantities (WP, 41, 42, 43, 44, 6) are assigned, a sequence of one of the system quantities (WP, 41, 42, 43, 44, 6) in each case being characterized by at least one event, wherein a delay of the at least one event is detected. On this basis, at least one actual value (I) over time for at least one event of at least one system quantity (WP, 41, 42, 43, 44, 6) is calculated within one measurement period to be predicted. The present invention makes it possible to provide a prediction of the system (2) or of one or a plurality of system quantities (WP, 41, 42, 43, 44, 6) based on flexible measurement periods. A future development of the system (2) or of the at least one system quantity (WP, 41, 42, 43, 44, 6) may not only be estimated roughly but instead may be calculated reliably under consideration of measurable data.

Abstract: A work flow system is described in which an originator of a task creates a new task description via a standard graphical user interface. The standard graphical user interface includes information regarding the task, together with a responsible entity for performing a task. An automatic email notification system notifies the responsible entity, whose leader accepts, rejects, or modifies a task, as necessary. Thereupon, the task report for the assigned/rejected/approved/modified item is automatically email reported to the originator and to anyone to whom the task has been assigned. The life cycle of the task is a complete loop such that the originator of the task is the only entity permitted to close the task, and must mandatorily do so for the task to be closed by the data base.

Abstract: Two methods check functional capability of electrical connections between address lines of a printed circuit board of a memory module and address line contacts of an integrated semiconductor memory chip mounted on the printed circuit board. Ruptured solder contacts are conventionally examined optically or investigated by electrical resistance measurements; however, the latter do not work in the case of memory modules with a number of semiconductor chips, the pin contacts of which are connected in parallel by the address lines. The methods make it possible to locate interrupted contacts on individual address lines by the indirect use of a write-read access to the semiconductor memory chip, specifically utilizing the misrouting of writing and reading commands produced by defective contact connections.

Abstract: A method and an apparatus for testing an SDRAM are described. The SDRAM is used as a main memory in the PC, and an additional circuit configuration is accommodated on a plug-in board and has an additional memory in the form of an SRAM and logic circuits. The method according to the invention allows the SDRAM to be tested in a module bank in the running PC to be set deliberately to a test mode. In this case the code for test mode activation is modified by a high-level language program (PASCAL) in accordance with the user requirements, is copied to the additional memory on the plug-in board, and is then called by the high-level language program using MS DOS. After activation of the selected test mode by a code programmed in Assembler, a defined jump is made back to the calling program once again. This allows the use of the test mode provided in the SDRAM in standard PCs and using standard operating systems. This greatly increases the test options for SDRAMs on standard PCs.

Abstract: Signal transit times on printed circuit boards which are equipped with all the passive components but without any active components can be determined using automatic standard test equipment composed of a standard test unit and a performance board with fittings attached thereto. In that first, using a standard routine of the test unit, a transit time is measured on the performance board from the CIF connector as far as the fitting, then a printed circuit board is plugged into the fitting location determined for it and then the sum transit time of the CIF connector is measured as far as the landing pad on the printed circuit board. By forming differences between the two measured values, the transit times on a printed circuit board can be measured with a high degree of precision with the automatic standard test equipment used in standard module testing technology.

At least one of the electrodes (16, 20) is provided with a contouring (24) on its side (22) that is exposed to the gas to be measured or to the reference gas, with the contouring being a trench-shaped groove (26) embossed into the surface of the electrode such that the electrode is pressed into the adjacent solid electrolyte in the region of the groove. According to the method, the embossing is done while the electrode and the solid electrolyte are in the non-sintered state, and the sensor is subsequently sintered.

Abstract: A liquid, foam or paste treatment medium is applied to a textile or similar web as the web is led through a gap in which the web is pressed resiliently against an opposing face in an area extending over the width of the web with non-uniform pressure by, for example, several adjacent cushions that are independently inflatable. The non-uniform pressure serves primarily to achieve uniform treatment, in particular, uniform coloring, despite the non-uniform conditions existing over the web width. The non-uniform pressure may also be used for imprinting patterns on the web.
