Abstract: A method for statistically distinguishing between two or more populations, such as between samples containing background and threat particles, is disclosed. According to one embodiment, the method for statistically distinguishing is a method for processing a signal in a particle detection system.

Abstract: A dissolved oxygen sensor having a cathode and anode immersed in an electrolyte is designed to provide a low background current in the sensor when a potential is applied to the cathode.

Abstract: A computerized method for analyzing data files finds association relationships between attributes recorded in the data files. The computer receives one or more data file records, each record containing two or more of attributes of interest. Software defines at least two attribute k-patterns by reference to a subset of the attributes, where k is an integer and represents the number of attributes that are included in a k-pattern. Using an invertible mapping algorithm, the software maps each of the at least two attribute k-patterns into an associated key and determines a distribution pattern for each of the at least two attribute k-patterns defined in step. The software then inverts the mapping to decode from the keys to the associated attribute k-pattern; and, using the keys, associates the distribution patterns determined with each of the at least two attribute k-patterns. Output is in the form of reports, detection signals and/or control signals.

Abstract: A control system includes a measurement device capable of gathering high frequency process parameter data, a modeling routine which uses the high frequency parameter data to develop a model of the high frequency noise and a compensation routine that employs the developed model to adjust a control signal to thereby compensate for the high frequency noise present within the process parameter.

The modeling routine analyzes the high frequency data and develops a mathematical model of the high frequency noise within the process variable.

Abstract: A light-extinction-type optical particle detection system comprises a laser producing a beam in response to a drive current amplitude reaching a lasing threshold, a view volume, and a light-extinction detector. The beam is characterized by mode-hopping noise energy produced by spurious switching of laser operating modes. The system comprises a signal generator producing the drive current such that its amplitude transitions across the threshold by a selected amount and at a selected frequency to cause the beam to operate simultaneously in multiple modes. The selected amount and frequency cooperate to spread the mode-hopping noise energy over a spectral range established by the number of modes, such that the detector does not appreciably respond to the mode-hopping noise energy.
