Publication number: 20110153223Abstract: Water droplets in exhaust gas that is, or was, analyzed by a remote emissions sensing system are detected. The detection may be made using measurements generally captured by the remote emissions sensing system during typical operation. As such, the detection may be applied “on site” as remote emissions sensing analysis is ongoing, or may be applied post hoc from data previously acquired by a remote emissions sensing system. The detection may be implemented without requiring additional sensors, more sophisticated sensors, and/or other additional or more sophisticated equipment being included in the remote emissions sensing system.Type: ApplicationFiled: December 21, 2009Publication date: June 23, 2011Applicant: ENVIRONMENTAL SYSTEMS PRODUCTS HOLDINGS INC.Inventors: ROBERT ALLEN GENTALA, PETER MILES MCCLINTOCK, DONALD HUGH STEDMAN

Patent number: 7400398Abstract: A system and method for correcting for “wavelength drift” in an RES system. One advantage provided by the invention includes the ability to correct for offset amounts of “wavelength drift” that are not divisible by an integer number of pixels (e.g., fraction pixel offset amounts) in an optical detector used in the RES system.

Patent number: RE40767Abstract: An unmanned integrated RES 12 integrates all of its components except the reflector 22 into a single console 30 that is positioned at the side of a road and has a CPU 36 that controls calibration, verification and data gathering. The RES's source 32 and receiver 34 are preferably stacked one on top of the other such that the IR beam 24 traverses a low and high path as it crosses the road 14. This allows the RES to detect both low and high ground clearance vehicles. To maintain the vehicle processing and identification throughput, the speed sensor 54 and ALPR 48,50 detect the passing vehicles at steep angles, approximately 20 to 35 degrees. In a preferred system, a manned control center 16 communicates with a large number of the unmanned integrated RES to download emissions data, perform remote diagnostics, and, if necessary, dispatch a technician to perform maintenance on a particular RES.Type: GrantFiled: November 9, 2000Date of Patent: June 23, 2009Assignee: Environmental Systems Products Holdings Inc.Inventors: Jay Peterson, David R Nelson, Troy P.
