Patent number: 9851296Abstract: A diagnostic system for measuring temperature, pressure, CO2 concentration and H2O concentration in a fluid stream is described. The system may include one or more probes that sample the fluid stream spatially, temporally and over ranges of pressure and temperature. Laser light sources are directed down pitch optical cables, through a lens and to a mirror, where the light sources are reflected back, through the lens to catch optical cables. The light travels through the catch optical cables to detectors, which provide electrical signals to a processer. The processer utilizes the signals to calculate CO2 concentration based on the temperatures derived from H2O vapor concentration. A probe for sampling CO2 and H2O vapor concentrations is also disclosed. Various mechanical features interact together to ensure the pitch and catch optical cables are properly aligned with the lens during assembly and use.Type: GrantFiled: November 18, 2016Date of Patent: December 26, 2017Assignee: UT-Battelle, LLCInventors: William P. Partridge, Jr., Gurneesh Singh Jatana, Ji Hyung Yoo, James E. Parks, II

Patent number: 9068933Abstract: A diagnostic system having a laser, an EGR probe, a detector and a processor. The laser may be a swept-? laser having a sweep range including a significant CO2 feature and substantially zero absorption regions. The sweep range may extend from about 2.708 ?m to about 2.7085 ?m. The processor may determine CO2 concentration as a function of the detector output signal. The processor may normalize the output signal as a function of the zero absorption regions. The system may include a plurality of EGR probes receiving light from a single laser. The system may include a separate detector for each probe. Alternatively, the system may combine the light returning from the different probes into a composite beam that is measured by a single detector. A unique modulation characteristic may be introduced into each light beam before combination so that the processor can discriminate between them in the composite beam.Type: GrantFiled: October 11, 2013Date of Patent: June 30, 2015Assignee: UT-Battelle, LLCInventors: James E.

Patent number: 9000374Abstract: A diagnostic system having a single-port EGR probe and a method for using the same. The system includes a light source, an EGR probe, a detector and a processor. The light source may provide a combined light beam composed of light from a mid-infrared signal source and a mid-infrared reference source. The signal source may be centered at 4.2 ?m and the reference source may be centered at 3.8 ?m. The EGR probe may be a single-port probe with internal optics and a sampling chamber with two flow cells arranged along the light path in series. The optics may include a lens for focusing the light beam and a mirror for reflecting the light beam received from a pitch optical cable to a catch optical cable. The signal and reference sources are modulated at different frequencies, thereby allowing them to be separated and the signal normalized by the processor.Type: GrantFiled: June 7, 2013Date of Patent: April 7, 2015Assignee: UT-Battelle, LLCInventors: James E.

Patent number: 8653830Abstract: Methods and apparatuses for evaluating a material are described. Embodiments typically involve use of an impedance measurement sensor to measure the impedance of a sample of the material under at least two different states of illumination. The states of illumination may include (a) substantially no optical stimulation, (b) substantial optical stimulation, (c) optical stimulation at a first wavelength of light, (d) optical stimulation at a second wavelength of light, (e) a first level of light intensity, and (f) a second level of light intensity. Typically a difference in impedance between the impedance of the sample at the two states of illumination is measured to determine a characteristic of the material.Type: GrantFiled: December 2, 2008Date of Patent: February 18, 2014Assignee: UT-Battelle, LLCInventors: Lonnie C.
