Patent number: 9784564Abstract: An optical measurement system includes an optical sensor assembly for measuring an object located beneath the optical sensor assembly. A deployment mechanism is pivotally connected relative to the optical sensor assembly that moves a secondary measurement aid, such as a touch sensor, between a deployed position and a retracted position. When in the retracted position, the secondary measurement aid does not inhibit movement of the optical sensor with respect to the object being measured.Type: GrantFiled: November 19, 2015Date of Patent: October 10, 2017Assignee: Quality Vision International, Inc.Inventors: Frederick D.

Patent number: 8542297Abstract: A process for pre-calibrating illumination sources permits illumination light intensities to be set to a near optimal level during training of an optical inspection system. Applicants have found that the illumination source intensities for a category of illuminators are sufficiently constant from machine to machine that the data collected during calibration of an illumination source on a machine using a particular type of source may be used on other machines of the same type using the same type of illumination source when combined with the reticle light intensity data for different zoom magnification's of the particular machine being used. That is, using known data for particular machine and the illumination source light intensity data for the same type of machine and illumination source permits accurate presetting of an illumination source.Type: GrantFiled: August 5, 2011Date of Patent: September 24, 2013Assignee: Quality Vision International, Inc.Inventors: Edward T. Polidor, Daniel C. Abbas

Publication number: 20080304774Abstract: This method and apparatus for pneumatic preloading of linear bearing assemblies is based on typical slide assemblies having ball bearing sets in rolling engagement with opposed and confronting bearing races slidably joining a base and a slide member. For adjustably preloading the bearing races, at least one and preferably a plurality of flexible, laterally expanding pneumatic tubes are positioned between a solid portion of the base and an adjustable member supporting a bearing race. Air pressure is then applied to the flexible tube(s), causing it/them to expand laterally and force confronting bearing races together to preload the bearing races. The adjustable member is then tightly secured to the base and the air pressure is removed. The tube(s) are left in position in a deflated state, and can be reused to perform the same procedure should it become necessary at a later time during the life of the assembly.Type: ApplicationFiled: June 11, 2007Publication date: December 11, 2008Inventors: Steven J. Gilbert, Edward T. Polidor, Edward J. Merrltt, JR.
