Field: Measurement (Instruments)
Classification: CPC G | IPC G

Claim 3:
4. The information processing apparatus according to claim 1, wherein
the smell sensor comprises a first sensory membrane being an inspection target and a second sensory membrane being a reference,
the model generating unit generates an ARX model for each of the sensory membranes by use of the input data and the output data for each of the sensory membranes,
the feature value computation unit
computes the first-order lag transfer function feature value for each of the sensory membranes by use of the ARX model for each of the sensory membranes, the information processing apparatus further comprising
a judgement unit that judges whether the first sensory membrane is an acceptable product, by whether a ratio of the first-order lag transfer function feature values each computed for each of the sensory membranes satisfies a reference.
