Abstract: Portable and wearable chemical detector devices, such as badges, that are analyte-general, rather than analyte-specific, and which provide an optimal way to notify and protect personnel against known and unknown airborne chemical hazards. The devices are advantageously low-cost, have low-power requirements, may be wearable and are designed to detect and alarm to a general chemical threat. A sensor device includes two or more sensor devices, a processing module coupled to each of the sensor devices and configured to process signals received from each of the two or more sensor devices to determine an environmental state; and a communication module that communicates information about the environmental state to a user.

Abstract: A system for monitoring an industrial process and taking action based on the results of process monitoring. Actions taken may include process control, paging, voicemail, and input for e-enterprise systems. The system includes an input module for receiving a plurality of parameters from a process for manufacture of a substance or object. The system also includes a library module. The library module includes a plurality of computer aided processes. Any one of the computer aided processes is capable of using each of the plurality of parameters to compare at least two of the plurality of parameters against a training set of parameters. The training set of parameters is generally predetermined. The computer aided process is also capable of determining if the at least two of the plurality of parameters are within a predetermined range of the training set of parameters. Additionally, the system includes an output module for outputting a result based upon the training set and the plurality of parameters.

Abstract: The present invention provides a distributed sensing system in a networked environment for identifying an analyte, including a first sensor array connected to the network comprising sensors capable of producing a first response in the presence of a chemical stimulus; a second sensor array connected to the network comprising sensors capable of producing a second response in the presence of a physical stimulus; and a computer comprising a resident algorithm. The algorithm indicates or selects the most relevant sensor in the network to identify the analyte. The sensors can be separated over large spatial areas, wherein the sensor arrays are networked. Suitable networks include a computer local area network, an intranet or the Internet.

Abstract: A system for capturing and transmitting analyte data pertaining to an unknown analyte. The system includes a device manager (102) and a processor manager (202). The device manager (102) is coupled to a number of module including a data capture module (104), a data formatting module (106) and a first input/output (I/O) module (108). The data capture module (104) is coupled to the device manager (102) for capturing the data for the unknown analyte at a first geographic location. The first data formatting module (106) is coupled to the device manager (102) for formatting or encoding the captured analyte data into a transmissible format before the captured analyte data are transmitted. The first I/O module (106) is coupled to the device manager for transmitting the captured analyte data via a computer network to a processor at a second geographic location.

Abstract: A mid-IR spectrometer attachment performs reflection spectroscopy measurements using commercially available infinity corrected light microscopes without degrading the microscope's performance. The mid-IR spectrometer attachment, which is mounted to and supported by the visible light microscope, introduces infrared radiation into the optical path of the microscope. Radiation from the mid-IR spectrometer source is directed by a trichroic radiation director to a mid-IR objective lens affixed to the microscope nosepiece. The objective lens focuses the radiation on to a subject sample surface in order to acquire either internally or externally reflected infrared spectra by subsequently directing the sample encoded reflected mid-infrared radiation to the radiation director and then to a mid-infrared radiation detection system.

Abstract: A system and method for establishing the cleanliness of a device by performing a test is described. The system includes an ion mobility spectrometer to measure target signal strengths, and to measure n2?1 test signal strengths of a device sample. The system also includes a statistics module to obtain a value of a statistical confidence-level parameter that is associated with a particular confidence level, and a pass range module to obtain a pass range of signal strengths from the value of the statistical confidence-level parameter and the n1 target signal strengths. The system also includes an averaging module to obtain an average test signal strength from the n2 test signal strengths, and a results module to determine that the device passes the test, indicating that the device is significantly clean to within the particular confidence level, if the average test signal strength lies in the pass range.

Abstract: A system and method for introducing and analyzing a sample containing an analyte using an ion mobility spectrometer are described. The system includes a temperature module for adjusting the temperature of the sample according to temperature instructions received, and a split ratio module for adjusting the split ratio according to split ratio instructions received. An ion mobility analyzer determines an ion mobility of the analyte. The ion mobility analyzer collects a plasmagram of the analyte to identify and quantitate the analyte.

Abstract: An opto-electronic image magnifying system. The magnifiying system includes: a light source (38, 39) which illuminates an object to be viewed; a miniaturized opto-electronic magnifier module (MOM), made of a lens (31) and a photodetector array (32), which receives the light from the illuminated object; an electronic circuit (34) which receives the signal from the MOM; a video-monitor (35) which receives the magnified signal from the electronic circuit and displays the image. The opto-electronic image magnifying system allows for small objects or features of small objects to be observed in which historically compound microscopes or specialized optical viewing systems were required to observe the small objects.
