Publication number: 20030120434Abstract: A remote emissions sensing system and method for sensing exhaust emissions from motor vehicles is provided where the system determines the opacity of an exhaust plume. The system comprises a radiation source that emits radiation which is passed through the exhaust plume of a motor vehicle to one or more detectors arranged to receive the radiation. A processor calculates the difference between the intensity of source radiation and the intensity of the radiation received by the detectors in first and second detection bands. The intensity difference in the second detection band measures exhaust opacity. If the exhaust opacity exceeds a predetermined level, the emissions data from other detection bands may be flagged as suspect or discarded. Alternatively, for a diesel powered vehicle, the exhaust opacity determination can be validated by a measurement of carbon monoxide in the exhaust plume.Type: ApplicationFiled: October 28, 2002Publication date: June 26, 2003Inventors: John DiDomenico, James H.

Patent number: 5870136Abstract: Methods, systems and computer products are provided for tracking objects within a scene using imperceptible structured light. The imperceptible structured light may be used in environments where humans work and therefore avoids disorienting observers. The structured light patterns are generated dynamically, allowing tracking without physical landmarks. Moreover, the occlusion of the generated landmarks is overcome by determining the position of objects using a determined camera position. The imperceptible structured light may be used in systems without tracking. The tracking may be used without imperceptible structured light.Type: GrantFiled: December 5, 1997Date of Patent: February 9, 1999Assignee: The University of North Carolina at Chapel HillInventors: Henry Fuchs, Mark Alan Livingston, Thomas Gary Bishop, Gregory Francis Welch

Patent number: 5607738Abstract: A mailer is comprised of multiple plies of carbonless paper secured one to the other along opposite edges by hot or cold adhesive. Pressure seal adhesive is applied along longitudinally and transversely extending tear strips of the intermediate assembly such that upon folding the plies about a medial scoreline, the pressure seal adhesives register with corresponding pressure seal adhesives on the opposite parts. SpeediSealer.RTM. equipment is used to apply pressure to the margins of the folded intermediate to adhere the parts to one another to form the mailer.Type: GrantFiled: August 29, 1995Date of Patent: March 4, 1997Assignee: Moore Business Forms, Inc.Inventor: Gary Bishop

Patent number: 5498872Abstract: A gas analysis device for the remote detecting, measuring and recording of NO, CO, CO.sub.2, HC, and H.sub.2 O levels from the exhaust (30) of moving motor vehicles (28) utilizes a source (11) of collimated infrared and ultraviolet radiation (15) and includes a detector unit (16) positioned on the opposite side of the roadway for receiving and measuring the infrared and ultraviolet radiation from the source (11) tranmitted through the vehicle exhaust. The detector unit splits the combined infrared and ultraviolet radiation into separate infrared and ultraviolet beams (42) and (40). The ultraviolet beam is diffracted onto a photodiode array in a spectrometer that generates a signal indicative of NO in the vehicle exhaust. A rotating reflector (27) time-multiplexes the infrared beam to a plurality of infrared sensors that generate electrical signals indicative of, for example, CO, CO.sub.2, HC, and H.sub.2 O in the vehicle exhaust. A computer (17) then computes the relative concentrations of CO, CO.sub.Type: GrantFiled: April 21, 1995Date of Patent: March 12, 1996Assignee: Colorado SeminaryInventors: Donald H.

Patent number: 5489777Abstract: A system for remote analysis of vehicle emissions also determines whether each vehicle's engine and exhaust system are hot or cold by measuring infrared radiation reflected by the roadway beneath the vehicle. A source transmits a beam of radiation through at least a portion of the motor vehicle exhaust to a number of sensors. Each sensor generates a signal indicative of the absorption of the beam in a wavelength band indicative of a corresponding exhaust gas (e.g., CO, CO.sub.2, HC, NO.sub.x and H.sub.2 O). An infrared detector measures infrared radiation within a field of view including at least a portion of the roadway beneath each passing vehicle. A processor then computes the concentrations of each exhaust gas from the sensor signals, and determines whether the vehicle is hot or cold by measuring the intensity of infrared radiation detected by the infrared detector.Type: GrantFiled: March 3, 1995Date of Patent: February 6, 1996Assignee: Denver SeminaryInventors: Donald H.

Patent number: 5210702Abstract: A gas analysis device for the remote detecting, measuring and recording of NO.sub.x, CO, CO.sub.2, HC and H.sub.2 O levels from the exhaust of moving motor vehicles. It utilizes a source of collimated infrared and ultraviolet radiation and includes a mechanism for receiving and measuring the infrared and ultraviolet radiation from its source, and another mechanism for measuring background infrared and ultraviolet radiation levels in the ambient atmosphere. The receiving mechanism splits the combined infrared and ultraviolet radiation into separate infrared and ultraviolet beams. A mechanism receives the separate ultraviolet beam and generates a signal indicative of NO.sub.x. Another mechanism splits the infrared beam into two to four components, and devices are positioned for receiving each of the infrared components and generating two to four signals indicative of, for example, CO, CO.sub.2, HC and H.sub.2 O. Another associated mechanism then computes and produces signals indicative of the amount of CO, CO.Type: GrantFiled: December 26, 1990Date of Patent: May 11, 1993Assignee: Colorado SeminaryInventors: Gary Bishop, Donald H.
