Edward Michael James 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).

  • Method for high speed EELS spectrum acquisition
    Patent number: 11024484
    Abstract: A system and method are disclosed for acquiring Electron Energy Loss Spectrometry (EELS) spectra in a transmission electron microscope. The inventive system and method maximize spectrum acquisition rate and duty cycle by exposing a first portion of an image sensor to a first spectrum while a previously exposed potion of the sensor is read out of the sensor during some or all of the exposure time.
    Type: Grant

  • High density fast phosphor for electron microscopy
    Patent number: 10364390
    Abstract: A fast-decaying, dense phosphor having relatively high light emission is described. Through a combination of material selection, growth and deposition technique, phosphor thin films are made that preserve the necessary light output when used in thin-films, unlike common fast phosphors, such as P-46, P-47, and also have an afterglow that decays much faster than common bright phosphors, such as P-43. Use of the phosphor is described in applications where acquiring many frames/images very quickly is required.
