Latest Patents
One of Freed's latest patents is a "System for multi-channel, diverged-beam optical wireless communication." This invention features an optical receiver designed for a diverged-beam, free space optical communications system. The optical receiver includes a demultiplexer and a detector array. The demultiplexer utilizes a diffractive optic to receive an optical beam propagating in free space, which contains multiple optical carrier signals of different wavelengths. This technology spatially separates the optical beam by wavelength into various communication channels. The detector array consists of multiple optical detectors that convert these optical carrier signals into corresponding electrical signals.
Another significant patent is the "Method of using carbon dioxide in recovery of formation deposits." This invention relates to systems and methods for providing a reliable, high-purity source of CO2 used in recovering formation deposits, such as fossil fuels. The process allows for the direct combustion or extraction of fossil fuels without the need to remove CO2, sulfur, or other impurities first.
