Abstract
A high temperature sensor for use with an induced vibration dynamic touch sensor system comprising a pad element adapted for sliding contact with an object so as to induce vibrations in the pad, a mechanical coupling means comprising a stiff, substantially straight member for coupling the pad to a transducer assembly, the transducer assembly for converting the vibrations into electrical signals. The electrical signals are processed to produce a normalized spectral signature characteristic of the size and shape of the object, and the sizes and shapes and nature of its surface features. A pattern vector is extracted from the spectral signature and subjected to discriminant analysis to classify and recognize the object.
