The present invention provides a non-invasive portable device and method for diagnosing an occlusion in coronary arteries of a patient. The diagnostic system includes a signal processor configured to receive signals from a group of acoustic sensors attached to the torso of a patient. The diagnostic device is configured with a processor to receive and generate an output on a display using a high end algorithm.

Systems and methods for measuring the integrity of insulation components in energized or de-energized electrical systems. Using a digital modulation/demodulation system, an active monitoring system adds a modulated high frequency signal to an injected signal and demodulates the resulting signal to provide voltages and currents that are measured and used to determine the capacitances and power factors of the insulation components. Systems may be used for on-line detection and measurement of power factor and capacitance of electrical equipment such as transformers, reactors, and condenser type bushings. The present disclosure is especially applicable to the electrical power industry.

A non-invasive diagnostic tool and method for detecting an obstruction in a coronary artery, the diagnostic tool including a signal processor adapted to receive signals corresponding to a heart beat from a plurality of acoustic sensors attached to the chest of a patient. The signal processor is programmed to identify a diastolic portion of the signals for a plurality of heartbeats and conduct a wavelet transform analysis on the diastolic signals for determining the existence of, as well as the severity and the location of, an obstruction in a coronary artery of the patient.

A partial discharge fault in a transformer tank is determined by sensing supersonic vibrations at a multiplicity of points about the tanks and establishing a threshold amplitude and a frequency range for pulse vibrations to be evaluated. The signals from the multiplicity of points are multiplexed, synchronized and localized and then processed in a series of steps. After the existence of triggering pulse vibrations exceeding an established threshold amplitude and within an established frequency and range is initially determined, a wavelet transform is conducted on the multiplexed signals two at a time with one signal being the signal from the first sensor found to provide a signal above the threshold amplitude. The wavelet transform provides both frequency and time domain. A scaling factor and translation parameters associated with the frequency of the vibrations are applied to obtain estimates of the time delays for the triggering pulse vibrations detected at the multiplicity of points, and the estimates of the transformed and scaled signals are then evaluated to determine the position of the partial discharge fault generating the triggering pulse vibrations.
