Patent number: 10591525Abstract: Various approaches can be used to interrogate a surface such as a surface of a layered semiconductor structure on a semiconductor wafer. Certain approaches employ Second Harmonic Generation and in some cases may utilize pump and probe radiation. Other approaches involve determining current flow from a sample illuminated with radiation. Decay constants can be measured to provide information regarding the sample. Additionally, electric and/or magnetic field biases can be applied to the sample to provide additional information.Type: GrantFiled: November 7, 2017Date of Patent: March 17, 2020Assignee: FemtoMetrix, Inc.Inventors: Viktor Koldiaev, Marc Kryger, John Changala

Patent number: 10380734Abstract: Method, system and computer program product for verification of jewelry items through comparison of images captured at different time intervals. The captured images show the images of gem holders which enable one or more gemstones to be held on the jewelry item. The images are stored in a database and compared to verify a change in the settings of the gem holders. A change in the metal part or the gemstones is detected based on the change in the settings of the gem holders and/or the difference of images. The valuation of the jewelry is determined to be changed on the basis of change in the metal part or the gemstones. The invention further allows displaying, evaluating, comparing and selling the jewelry item through an online commerce platform connected to the database.Type: GrantFiled: February 27, 2017Date of Patent: August 13, 2019Inventors: Aniket Bharat Parikh, Archana Aniket Parikh

Patent number: 10318515Abstract: A method and system for generating a clarity grading look-up table includes collecting actual inclusion parameter data for a plurality of gems, where the actual inclusion parameter data includes an actual clarity grade and an actual inclusion parameter data combination. A mathematical relationship between a clarity grade and a particular inclusion parameter combination is then extrapolated from the actual inclusion parameter data. A derived clarity grade is then assigned to a plurality of inclusion parameter combinations as a function of the mathematical relationship and a set of inputted inclusion parameters. Also, a method and system for providing a clarity grade includes receiving a plurality of inclusion characteristics associated with a gem and parameterizing each of the inclusion characteristics, so that a parameter value is assigned to each inclusion characteristic. The parameter values are then input to a mathematical formula so as to provide a parameterized clarity grade for the gem.Type: GrantFiled: May 11, 2016Date of Patent: June 11, 2019Assignee: GEMOLOGICAL INSTITUTE OF AMERICA, INC.
