Latest Patents
One of her latest patents is titled "Machine vibration monitoring." This invention presents a system and method for monitoring vibrations in machines with rotating elements. The system measures and filters composite vibration signals into discrete vector components associated with the machine's operating frequency. The filtered vectors are evaluated to obtain a mean and standard deviation, allowing for the establishment of trip conditions that can initiate specific actions based on the conditions met. Additionally, the operating conditions of the machine can be displayed on a computer interface alongside the discrete vector components.
Another notable patent is "Combustion anomaly detection via wavelet analysis of dynamic sensor signals." This invention addresses the detection of combustion anomalies within gas turbine engines. A sensor associated with the combustor measures signals that represent combustion conditions. The sampled dynamic signal is divided into time segments to derive multiple data points. A wavelet transform is performed to calculate wavelet coefficients, which are then normalized by a baseline signal. This process enables the detection of combustion anomalies by comparing the normalized amplitudes of the wavelet coefficients to predetermined threshold amplitudes.
