  • Patent number: 9646261
    Abstract: The present invention is a biometric security system and method operable to authenticate one or more individuals using physiological signals. The method and system may comprise one of the following modes: instantaneous identity recognition (MR); or continuous identity recognition (CIR). The present invention may include a methodology and framework for biometric recognition using physiological signals and may utilize a machine learning utility. The machine learning utility may be presented and adapted to the needs of different application environments which constitute different application frameworks. The present invention may further incorporate a method and system for continuous authentication using physiological signals and a means of estimating relevant parameters.

  • Publication number: 20070031058
    Abstract: The present invention relates to a method for blind reconstruction of multi-frame image data. Multi-frame image data corresponding to at least two image frames are received. Using a filter function the image data corresponding to each of the at least two image frames are filtered. The filtered image data are then classified producing data indicative of a classified image for each of the at least two image frames. In a following step the filtered image data are fusion-based classified producing data indicative of a classified fused image. By superposing the corresponding data indicative of the classified image with the data indicative of the classified fused image an error function is determined for each of the at least two image frames. Using the error function the filter function for each of the at least two image frames is then updated. This process is repeated until a stopping criterion is met.

  • Publication number: 20060253040
    Abstract: A method and a device for measuring blood pressure and heart rate is disclosed. Blood pressure signals corresponding to the Korotkoff sounds are detected using an array of primary acoustic sensors. A secondary acoustic sensor is used for detecting noise and vibrations. The signals provided by the primary acoustic sensors are then processed using adaptive linear beamforming and are combined into a single signal. The combined signal is then provided to an adaptive interferer canceller together with the signal of the secondary acoustic sensor for removing noise and vibration effects. Artifacts due to a patient's motion are removed in a following post-processing step. The post-processed signal and the pressure signal are then graphically displayed enabling a trained user to correct the automatic measurement, to decide whether a repeat measurement is necessary, and to quickly and accurately diagnose heart pulse patterns.
