  • Xenon collection method and system
    Patent number: 10226731
    Abstract: A method and system for collecting xenon (Xe) is described. A microchannel heat exchanger is used in combination with a mechanical cooler and an absorbent. A combination of components makes up a Xe Collection Subsystem that is adapted for use in an efficient process for collecting, purifying, and measuring Xe isotopes collected from air as part of the International Monitoring System.
    Type: Grant
    Filed: June 19, 2018
    Date of Patent: March 12, 2019
    Assignee: Battelle Memorial Institute

  • Systems and methods for free space optical communication
    Patent number: 7941050
    Abstract: Free space optical communication methods and systems, according to various aspects are described. The methods and systems are characterized by transmission of data through free space with a digitized optical signal acquired using wavelength modulation, and by discrimination between bit states in the digitized optical signal using a spectroscopic absorption feature of a chemical substance.

  • Laser-based spectroscopic detection techniques
    Patent number: 7102751
    Abstract: One embodiment of the present invention includes: a modulated laser light source to transmit an interrogation light beam to a region including a substance for spectroscopic evaluation, a detector responsive to modulated light from the region to provide a corresponding modulated signal, and a signal processing subsystem responsive to the modulated signal to generate a spectroscopic absorption peak representation. This subsystem also estimates absorbance based on a derivative form of an absorption peak and a residual amplitude modulation level corresponding to the absorption peak.
