APPARATUS AND METHOD FOR GENERATING A CONDITION INDICATION

摘要

An apparatus for generating a condition indication using a time sequence of data values, each data value representing a physiological measure of a condition of a subject at a time, includes: a transformer for transforming the time sequence of data values into a transformed sequence of data values using a transform rule, wherein the transform rule is such that a certain characteristic in a time course of the physiological measure is represented by the transformed sequence of data values is more linear than the time course before the transform; a rate of change calculator for calculating an estimated rate of change for the transformed sequence of data values; and a processor for processing the estimated rate of change to output the condition indication.

1. Apparatus for generating a condition indication using a time sequence of data values, each data value representing a physiological measure of a condition of a subject at a time, comprising:
a transformer configured to transform the time sequence of data values into a transformed sequence of data values using a transform rule, wherein the transform rule is such that a certain characteristic in a time course of the physiological measure as represented by the transformed sequence of data values is more linear than the time course before the transform, said transformer comprising:
an estimated probability function calculator configured to calculate an estimated probability function associated with a set of data values; anda transform calculator configured to calculate the transform rule using a predetermined target probability function being different from the estimated probability function; a rate of change calculator configured to calculate an estimated rate of change for the transformed sequence of data values; and a processor configured to process the estimated rate of change to output the condition indication, wherein at least one of the transformer, rate of change calculator and processor include a hardware implementation.
