  • Optoelectronic and microfluidic integration for miniaturized spectroscopic devices
    Patent number: 7524459
    Abstract: Techniques for integrating optoelectronic system and microfluidic system. An apparatus for optical analysis includes a detector system and a microfluidic system on the detector system. The apparatus is free from any lens system between the microfluidic system and the detector system. Methods of making such an apparatus and using such an apparatus are also disclosed.

  • Real-time spatio-temporal coherence estimation for autonomous mode identification and invariance tracking
    Publication number: 20030018928
    Abstract: A general method of anomaly detection from time-correlated sensor data is disclosed. Multiple time-correlated signals are received. Their cross-signal behavior is compared against a fixed library of invariants. The library is constructed during a training process, which is itself data-driven using the same time-correlated signals. The method is applicable to a broad class of problems and is designed to respond to any departure from normal operation, including faults or events that lie outside the training envelope.
