  • Patent number: 6801879
    Abstract: A method for monitoring processes includes identifying process variables in a process space as operating values, carrying out a measurement of actual values of the operating values, presetting or measuring actual values of at least one operating parameter that influences these operating values, assessing operating values as a function of the operating parameters, and generating a map of the process space by allocating at least one subset of points of the process space to at least two classes which represent a measure of the risk of the operating state of the printing machine. An apparatus for implementing the above-described method has at least one diagnostic apparatus, an input unit, a machine control unit and a display apparatus. The apparatus also has a cartography unit which provides a map of the process space of the operating values as a function of the operating parameters.

  • Patent number: 6799128
    Abstract: A measurement system for analyzing data values that are stored in memory and that represent a sampled electrical signal under analysis (SUA). Each of the data values represents the SUA at respective points in time over a time interval during which the SUA was sampled. The stored data values constitute a main data record. The system includes processing logic that is configured to generate at least a first reduced data record from the main data record. The first reduced data record comprises a subset of the data values of the main data record. The first reduced data record is processed by the processing logic to locate an edge (i.e., a voltage transition) in the first reduced data record. Thus, it is not necessary that the main data record, which is more voluminous than the first reduced data record, be used to locate the edge.

  • Patent number: 6761057
    Abstract: A method of detecting errors in air data sensing systems having multi-function probes being used in combinations to define probe systems includes a step (A) of, for each probe system, making a first prediction of an aircraft parameter as a function of local angles of attack at two member probes of the particular system, and making a second prediction of the aircraft parameter as a function of local pressure ratios at the two member probes of the particular system. A step (B) is performed in which, for each of the probe systems, the first and second predictions of the aircraft parameter are compared to determine whether the first and second predictions are within a predetermined threshold of each other. Then, a step (C) is performed in which, for each of the probe systems, if the first and second predictions of the aircraft parameter are not within the predetermined threshold of each other, then the particular probe system is identified as having a malfunctioning member probe.

  • Patent number: 6760690
    Abstract: A CPU of an effector calculates envelopes of an impulse response waveform from sample data of impulse response waveform data supplied from a microphone via an A/D converter circuit. Next, CPU detects a section during which a slope of the detected envelopes takes a value near “0” during a predetermined time or longer. CPU calculates an average value of sample data during the detected section to correct a DC offset. Thereafter, CPU acquires a maximum value of absolute values among the sample data during the detected section, and determines this maximum value as a background noise component value. The background noise components are removed from each sample data constituting the impulse response waveform data.
