Publication number: 20150253127Abstract: Non-contacting caliper measurements of free-standing sheets detect mid-IR interferometric fringes created by the reflection of light from the top and bottom surfaces of the sheet. The technique includes directing a laser beam at a selected angle of incidence onto a single spot on the exposed outer surface and scanning the laser beam through a selected wavelength range as the laser beam is directed onto the exposed outer surface and measuring the intensity of an interference pattern that forms from the superposition of radiation that is reflected from the exposed outer surface and from the inner surface. Alternatively, the intensity of an interference pattern formed from the superposition of radiation that is directly transmitted through the web and radiation that is transmitted through the web after internal reflections from the internal surfaces of the web. Thickness can be extracted from the fringe separation in the interference pattern.Type: ApplicationFiled: March 4, 2014Publication date: September 10, 2015Applicant: Honeywell ASCa Inc.Inventors: Michael Kon Yew Hughes, Sebastien Tixier, Stephane Savard

Patent number: 9007589Abstract: Dual mounting head scanners measure the thickness of flexible moving porous webs and employ an air clamp on the operative surface of the lower head to maintain the web in physical contact with a measurement surface. As the web is held firmly by the clamp, the vacuum level that is established is indicative of the porosity of the membrane. As compressed air is supplied to a vacuum generator at a given operational pressure, the rate of airflow through the web can be inferred from the vacuum pressure measurements. The rate of airflow through the membrane and therefore the porosity of the membrane are related to the vacuum level. It is not necessary to measure the airflow through the membrane. From the vacuum pressure measurements, the membrane's permeability can also be determined by correlation to empirical data. Thickness measurements are effected by optical triangulation and inductive proximity measurements.Type: GrantFiled: September 16, 2013Date of Patent: April 14, 2015Assignee: Honeywell ASCa Inc.Inventors: Michael Kon Yew Hughes, Sebastien Tixier, Stuart James Heath

Patent number: 8760669Abstract: Dual mounting head scanner system measures the thickness of a flexible continuous moving web such as paper by employing an optical senor positioned in the upper head to determine the distance between the optical sensor and the upper surface of the paper while a displacement sensor positioned in the lower head determines the distance between the displacement sensor, which includes an RF coil, and a reference surface on the upper head. An air clamp and vacuum source assembly on the operative surface of the lower head maintains the moving web in physical contact with a measurement surface that is incorporated in the operative surface. The optical sensor directs incident radiation onto the web at the measurement surface. Thermal isolation of the two sensors eliminates thermal interactions.Type: GrantFiled: September 30, 2011Date of Patent: June 24, 2014Assignee: Honeywell ASCa Inc.Inventors: Stuart James Heath, Michael Kon Yew Hughes, Graham Duck

Patent number: 8527212Abstract: Radiation scattering is one of the main contributors to the uncertainty of near infrared (NIR) measurements. Enhanced absorption-measurement accuracy for NIR sensors is achieved by using a combination of NIR spectroscopy and time-of-flight techniques to select photons that are the result of a given mean free path within a moving sample target. By measuring absorption as a function of path length or by windowing signals that are attributable to excessive scattering of NIR radiation within the sample, this technique affords the calculation of more accurate and more universal calibrations. The NIR sensor employs short or ultra-short laser pulses to create NIR that is directed to the moving sample and emerging radiation is detected over time. Windowing effectively truncates non-contributing measurements.Type: GrantFiled: February 14, 2011Date of Patent: September 3, 2013Assignee: Honeywell ASCa Inc.Inventors: Michael Kon Yew Hughes, Sebastien Tixier

Patent number: 8083896Abstract: An air stabilization system employing two parallel, opposite-facing Coanda nozzles, with each nozzle exhausting gas at opposite directions, subjects a moving flexible web to opposing forces effective to create local tension within the web. Each nozzle includes an elongated slot that is perpendicular to the path of the moving web. The nozzles serve as separate points along the machine direction for controlling the height of the web. The operative surface with the nozzles can exhibit a flush surface. The nozzles can be formed on elevated structures on the operative surface. The operative surface can be covered with a transparent substrate to minimize shape distortions on the moving web and to prevent debris from collecting around the sensor. An internal baffle is employed to channel air flow within each nozzle. The baffle equalizes the gas pressure across the nozzle and directs air flow towards it.Type: GrantFiled: August 25, 2009Date of Patent: December 27, 2011Assignee: Honeywell ASCa Inc.Inventor: Michael Kon Yew Hughes
