  • Patent number: 8650932
    Abstract: A detection and identification system includes a sensor unit (100) having a sensor array that detects and identifies at least one chemical included in an air flow. The system also includes a pump (120) that drives the air flow through the detection and identification system, in which the pump receives the air flow that has passed out of the sensor unit. The system further includes an adsorption unit (130) that dries and cleans the air flow within the detection and identification system, to obtain a substantially dry and clean air flow, in which the adsorption unit receives the air flow that has passed out of the pump. The system also includes at least one valve (140) that receives the substantially dry and clean air flow that has passed through the adsorption unit. The valve provides the substantially dry and clean air flow to the sensor unit in a close-loop circulation operation to thereby clean a sensor array.

  • Publication number: 20110098974
    Abstract: A method and system for detecting and classifying sensor data, includes obtaining at least one feature vector from a sample to be analyzed, the sample to be analyzed being applied to an array of sensors that includes at least two differential sensors. The method and system also includes converting the at least one feature vector to at least one ratio-metric feature vector. The method and system further includes comparing the at least one ratio-metric feature vector to a detection threshold, and outputting an alarm to denote that the sample is abnormal when the detection threshold is exceeded. When the at least one ratio-metric feature vector does not exceed the detection threshold, the method and system includes classifying the sample as normal and feeding back the at least one ratio-metric feature vector to recompute the detection threshold for future samples to be detected and classified.
