Optically Driven Control Circuitry for Reconfigurable Surfaces
Invention Description Recent advancements in 5G and 6G networks operating at mmWave and THz frequencies promise higher speeds but face new challenges including free-space losses and hardware constraints. Reconfigurable intelligent surfaces (RISs) address these challenges by dynamically manipulating electromagnetic waves using hundreds to thousands...

Esterification, Acetalization and/or Ketalization to Upgrade Bio-oils to Boiler or Space Heating Fuels
Overview of Technology The technology is a development of a bio-oil sonification and esterification process that reduces bio-oil water content and acidity while significantly increasing higher heating value (HHV). The increase in HHV moves bio-oil to an energy level of 80% of No. 2 fuel oil, making the upgraded bio-oil much more competitive as a liquid...

Chance-Constrained Optimization for Treatment of Prostate and Other Cancers in Intensity-Modulated Proton Therapy
The quality of IMPT treatment plans may be drastically diminished by uncertainties such as proton range and patient setup errors. If these uncertainties are not figured into treatment planning, the dose distribution that the patient receives may not be the same as the planned dose distribution. New treatment plans, which include optimized software/programming,...
