A method, a system and an arrangement for predicting at least one system event and a corresponding computer program and a corresponding computer-readable storage medium are configured so that it is possible to predict a system event based on trends in observables over a certain period of time prior to the event occurring. One example of a system event is the failure of a system because the abnormal behavior of a component is reflected in irregularities in one or a plurality of observables. Another example of a system event is the early recognition or pre-acute prediction of a specific critical condition of a patient.

A method, a system and an arrangement to predict at least one system event and a corresponding computer program and a corresponding machine-readable storage medium are configured so that the event is predictable because of trends in observables over a certain period before the occurrence of the events. The method, system and arrangement can be used in particular for patient-specific monitoring of patho-physiological changes but also in geophysical or abstract units such as population or economic systems in which the deviation from a defined normal condition is predicted.

Methods and apparatuses for detecting sleep apnea by analyzing characteristic physiological oscillations of the heart rate variability (HRV). Starting from recorded ECG data of the patient, for example, as a long-term sequence of the changing RR intervals, the heart rate variability is examined using autocorrelation calculations for the occurrence of rhythmic oscillations of various frequencies. If oscillations typical for apnea occur having very long period durations in the range of 20 to 80 seconds, these are detected as a maximum of the autocorrelation function. If a pathological sleep apnea accordingly exists, individual apnea events may be identified by prompt analysis of short recorded RR sequences, e.g., in the minute interval.

A process for detecting the physical positions or changes of position of a human being based on detecting a physiological signal dependent on a sympathetic/parasympathetic nerve system in each case in the heart or in a vessel near the heart by means of a sensor at pre-specified times, in particular, based in each case on a physiological or stimulation event, deriving a value of a signal parameter in each case, from this signal according to a pre-specified signal processing rule and stored determining a fluctuation curve of the stored signal parameter values, performing a frequency analysis of the fluctuation curve to obtain the spectral power density evaluating the spectral power density, resulting in the issuance of a position signal as a function of the evaluation result, whereby the morphology of the signals is detected and the value of the signal parameter is, in each case, derived from morphology of an individual detected signal.

A composition of inorganic powders comprises inorganic powder, dispersant and binder. The dispersant and/or binder used is a block copolymer of the units methacrylic acid and alkyl methacrylate in which the alkyl radical can comprise from 1 to 8 carbon atoms. The individual blocks of alkyl methacrylate possess an average molecular weight of at least 4000 and the total block copolymer has an average molecular weight of up to 150,000, in each case expressed as number average (M.sub.n).
