Latest Patents

One of her latest patents is focused on the "Indoor identification of individuals through footstep induced structural vibration." This invention introduces an indoor person identification system that utilizes the capture and analysis of footstep induced structural vibrations. The system senses floor vibration and detects the signal induced by footsteps. It then extracts features from the signal that represent characteristics of each person's unique gait pattern. With these extracted features, the system conducts hierarchical classification at an individual step level and at a collection of consecutive steps level, achieving a high degree of accuracy in the identification of individuals.

Another notable patent is the "System to enable rail infrastructure monitoring through the dynamic response of an operational train." This invention relates to a vehicle-based infrastructure diagnostic apparatus to assist in the maintenance of rail networks. It is a complete system—from the acquisition of vibration signals in a moving vehicle to the presentation of the infrastructure changes to the maintenance workers. This apparatus relies on novel techniques to account for the variable speed of the train, making it useful even on non-dedicated rail vehicles, and novel techniques to normalize for various environmental conditions. This system could help maintenance departments identify and remediate anomalies more rapidly, as well as trace network deterioration over time. The apparatus consists of low-cost unobtrusive sensors, software for data analysis, and hardware that makes it easy to deploy widely even on existing rail networks.
