摘要:
A procedure for operating a particle sensor that is arranged downstream after a particle filter, at which an ash contamination can occur, and a device for implementing the procedure, are suggested. A remaining operating time determination determines the remaining operating time of the particle sensor related to an ash contamination. Alternatively or additionally the remaining operating time determination provides a correction signal, with which the sensitivity loss of the particle sensor caused by the ash contamination can be considered.

In the English translation document, please add the paragraph at page 17 line 1, after the newly added ABSTRACT section heading, as follows: The invention relates to a method and a control device for requesting e-mail related information from an e-mail server, using a telephone. An entry via the telephone prompts a connection between the control device and the e-mail server to be established and also the transmission of the requested information from the e-mail server to the control device, e.g. a media gateway controller. The requested information is transmitted to the telephone and displayed on the latter by the control device. The invention permits access to e-mail messages using various types of telephone, such as e.g. an analog telephone, an ISDN telephone and a mobile telephone. The availability of information in the form of e-mail is thus increased. The invention also permits more flexible access to e-mail information in situations where an internet terminal is lacking.
摘要:
A Roebel bar (10) for an electrical machine comprises a plurality of essentially parallel, transposed conductor elements (11, 12, 13), which, lying over and/or next to one another, form a bar with an essentially rectangular cross section, which is surrounded on the outside by an insulation (19) and has between the insulation (19) and the conductor elements (11, 12, 13) means (14, 14′; 15, 15′; 17, 18) for forming an inner corona protection (ICP). In the case of such a Roebel bar, particularly effective inner corona protection is achieved by the fact that the means for inner corona protection comprise preformed, angled profiles (17, 18) of an electrically conducting material, which, running in the longitudinal direction of the Roebel bar (10), enclose the edges of the bar formed by the conductor elements (11, 12, 13), and to which the insulation (19) is applied.

摘要:
A non-contact thermal imaging system based on infrared radiation detection is described which uses an energy source to provide a beam of energy that strikes a sample to be analyzed. The energy beam produces a thermal wave in the sample, there being infrared radiation emitted from the thermal wave. All of the infrared radiation emitted from the heated area of the sample is collected and directed to an infrared detector, to have a two-dimensional image of the sample. This is used to detect surface and sub-surface structure, defects, etc. The use of a focussed energy beam, such as a laser or electron beam, offers advantages. In this technique, all points of the sample are treated equally and the results are very easily interpreted to know the exact location and type of structure that is imaged in the heated area. An ellipsoidal collector is preferrably used to image the emitted infrared radiation onto the detector, where the sample is located at one focal point of the ellipse, and the detector is located at the other focal point.
摘要:
The invention relates to a method for operating a drive device (1), which for the purpose of providing a driving torque comprises an internal combustion engine having a plurality of cylinders (10, 11, 12, 13) that, during normal operation, supply a respective torque contribution, and at least one electric motor (3) operatively connected to said engine. To this end, in a diagnostic mode a cylinder-selective measurement of at least one characteristic operating variable is carried out, for which purpose in the diagnostic mode only the cylinder (10, 11, 12, 13) to be measured is operated and the torque contributions of the remaining cylinders (10, 11, 12, 13) are simulated by the electric motor (3).
