Patent number: 8994933Abstract: An apparatus and method are provided for characterizing a replica tape which has been embossed, compressed or cast on a surface of a material to be measured to replicate that surface. The replica tape is secured between first and second holding components such that a compressible surface of the replica tape is secured against the first holding component. A light source transmits light through the second holding component, the replica tape and the first holding component. An image sensor measures intensity of the light respectively transmitted through at least two measurement points of the compressible surface of the replica tape. A processing unit converts the measured light intensity transmitted through the at least two measurement points into at least two data values each respectively relating to a measurement statistic of the replica tape at a corresponding one of the at least two measurement points, respectively.Type: GrantFiled: January 9, 2014Date of Patent: March 31, 2015Assignee: DeFelsko CorporationInventors: Leon Vandervalk, Robert V.

Publication number: 20150077738Abstract: 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 interred 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: ApplicationFiled: September 16, 2013Publication date: March 19, 2015Applicant: Honeywell ASCa Inc.Inventors: Michael Kon Yew Hughes, Sebastien Tixier, Stuart James Heath
