A method monitors a weld signature of a welding apparatus by processing the signature through a neural network to recognize a pattern, and by classifying the weld signature in response to the pattern. The method determines if the weld signature is sufficiently different from training weld signatures stored in a database, and records the weld signature in the database when sufficiently different. The method tests a weld joint to determine values of different weld joint properties, and then correlates the signature with the weld data to validate the database. An apparatus monitors a weld signature during a welding process to predict welding joint quality, and includes a welding gun, a power supply, and a sensor for detecting welding voltage, current, and wire feed speed (WFS). A neural network receives the welding process values and classifies the signature into different weld classifications each corresponding to a predicted welding joint quality.

A method tests a plasma processing system having a chamber, an RF power source, and a matching network. An RF power signal is generated from the RF power source to the chamber without igniting any plasma within the chamber. The voltage of the RF power signal, the current of the RF power signal, and the phase of the RF power signal, received by the chamber is measured while holding other parameters affecting the chamber constant. A value representative of an impedance of the chamber is computed based on the voltage, the current, and the phase. The value is then compared with a reference value to determine any defects in the plasma processing system. The reference value is representative of the impedance of a defect-free chamber.

The invention relates to a method and apparatus for assessing the reactivity observable in a certain physiological signal, especially the EEG signal, of a comatose subject. In order to obtain an objective and a reliable measure of the reactivity automatically and without the presence of a trained EEG specialist, a valid signal model is constructed for an EEG signal obtained from the subject. A time reference corresponding to a stimulus is applied and further signal data is obtained from the time series, the further signal data being subsequent to the time reference. By employing the further signal data, the method tests whether the signal model remains to be a valid signal model for the EEG signal also after the stimulus, and indicates, based on the test, whether reactivity is present in the physiological signal.
