Eric Garfunkel has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11248904
    Abstract: Systems and methods for measuring a curvature radius of a sample. The methods comprise: emitting a light beam from a laser source in a direction towards a beam expander; expanding a size of the light beam emitted from the laser source to create a broad laser beam; reflecting the broad laser beam off of a curved surface of the sample; creating a plurality of non-parallel laser beams by passing the reflected broad laser beam through a grating mask or a biprism; using the plurality of non-parallel laser beams to create an interference pattern at a camera image sensor; capturing a first image by the camera image sensor; and processing the first image by an image processing device to determine the curvature radius of the sample.
    Type: Grant

  • Publication number: 20130266501
    Abstract: Method for making graphene sheets exfoliated by oxidation from graphite by mixing graphite powder with a solution of concentrated sulfuric acid and nitric acid and subjecting the resultant mixture to microware irradiation until a finely dispersed suspension graphene sheets is formed in the solution. Graphene sheets exfoliated by oxidation from graphite are also disclosed.
