  • Publication number: 20130042698
    Abstract: A method and an apparatus for determining at least one flow characteristic of an essentially laminarly flowing, gaseous or liquid medium in a pipeline. Distinguishing features include: that at least one modulation element introduced into, or placed in, the pipeline produces, at least for the case, in which the medium is flowing with a velocity different from zero, a change in density of the medium, at least at times, in the vicinity of the modulation element; that at least one mechanically oscillatable unit introduced into, or placed in, the pipeline and spaced from the modulation element is excited to resonant oscillations; that mechanical oscillations are received by the mechanically oscillatable unit and converted into an electrical, received signal, wherein the received signal is sensitive to the density change; and that the at least one flow characteristic of the medium is determined from the reaction of the received signal of the mechanically oscillatable unit to the density change.

  • Patent number: 8245628
    Abstract: A coffee machine comprising an instantaneous electric heater for heating water, which is transported from a storage tank and conducted under pressure after the heating process into a brewing chamber to prepare the coffee, said chamber comprising an outlet nozzle for discharging the prepared coffee. The machine also comprises at least one sensor for recording an electric measured value that correlates to the temperature of the heated water and a control system for controlling the pump output of the pump and/or the heating output of the instantaneous heater in accordance with the measured value. The device permits a blockage of the nozzle to be identified and safely removed. The control system shuts off the pump output and/or the heating output if the measured value exceeds predefined thresholds and blocks a restart of the pump output and/or heating output for a specified blocking period by activating blocking elements.

  • Publication number: 20120158363
    Abstract: A method for monitoring the functioning of a field device, wherein the field device provides a complex measurement signal, which is produced from a number of individual measurements following one another in time, comprising method steps as follows: the complex measurement signals are stored within a predetermined time window; the occurrence of a predetermined event is monitored in the field device; the stored complex measurement signals are overwritten for the case, in which the predetermined event does not occur within the predetermined time window; for the case, in which the predetermined event occurs within the predetermined time window, both a first defined number of complex measurement signals, which were ascertained in time directly before the occurrence of the event, are frozen, as well as a second defined number of complex measurement signals, which were ascertained in time directly after the occurrence of the predetermined event, are stored.

  • Publication number: 20100146942
    Abstract: An exhaust system of an internal combustion engine, in particular of a vehicle, has an insert through which exhaust gas flows, for purifying the exhaust gas, and a mixing chamber through which exhaust gas flows and which is arranged upstream of the insert through which exhaust gas flows. The mixing chamber includes at least one permeable wall and is arranged on a channel wall of the exhaust system and protrudes radially into the interior of the exhaust system. The exhaust system further has a vaporizer device that vaporizes an oxidizable liquid and introduces the vapor into the mixing chamber, and an ignition device that protrudes at least partly into the mixing chamber. The vaporizer device includes a glow element which is configured and heatable in such a way that an auto-ignition of the oxidizable vapor occurs on its surface.

  • Patent number: 7730760
    Abstract: A method for checking proper functioning of a fill-level measuring device working according to the travel time principle. For this purpose, in predetermined or selectable time intervals (ta), a current measured value curve at a current fill level (hactual) is ascertained; on the basis of the current measured value curve, a current wanted echo signal is determined. Subsequently, on the basis of the current wanted echo signal, an expected value (E) for quality of a wanted echo signal at least one predetermined fill level (hdesired) is ascertained. The ascertained expected value (E) for quality of the wanted echo signal at the predetermined fill level (hdesired) is compared with a predetermined critical value for quality, and an error condition is diagnosed, when the ascertained expected value falls below the critical value for quality.
