Abstract: Methods, systems, and devices for PFAS destruction including providing water containing PFAS to a reactor vessel, irradiating the water with UV light under conditions to destroy at least a portion of the PFAS, passing the treated water through a selective membrane to form permeate and membrane reject comprising PFAS, providing the membrane reject back to the reactor vessel, providing additional water containing PFAS to the reactor vessel within the reactor vessel or before being provided to the reactor vessel, and irradiating the membrane reject and the additional water containing PFAS within the reactor vessel with UV light. The steps may be repeated a plurality of times such that PFAS that is not destroyed is recycled through the reactor vessel. Sensitizers may be added and may also be recycled in the membrane reject with the PFAS.

Abstract: Methods, systems and devices for PFAS destruction including removing nitrate from water containing PFAS, combining the water with a sensitizer and a sufficient quantity of base to create a treatment solution having a pH of about 10 or more, and irradiating the treatment solution with UV light in a photoreactor to destroy a portion of the PFAS. The nitrate may be removed electrolytically such as by electrolytically reducing nitrate to nitrogen gas and/or ammonia. The nitrate may be removed by filtration through a selective membrane, such as by reverse osmosis, forward osmosis, nanofiltration, and/or ultrafiltration. The system may include electrolytic cell system including a first cell with a cathode contacting the water containing PFAS in the first cell, a second cell including an anode in an electrolytic solution, a power source, and a salt brine and/or membrane separating the first and second cells.

Abstract: Systems and techniques for enabling interaction with physical objects as proxy objects representing virtual objects are provided herein. Virtual reality application data associated with a virtual reality application executed on a virtual reality device, a first virtual reality object data associated with a first virtual reality object from the virtual reality application, and virtual reality event data associated with one or more events from the virtual reality application may be received. Robotic arms including a robotic hand may grasp a first physical object which corresponds to the first virtual reality object of the virtual reality application. Sensors may detect a user interaction with the first physical object. Force feedback instructions commanding the robotic arms to move while maintaining grasp of the first physical object may be generated and executed based on detecting the user interaction with the first physical object and based on the virtual reality event data.

Abstract: A system and method for remapping surface areas of vehicle environment that include receiving a plurality of images of the surface areas of the vehicle environment from a computing device. The system and method also include evaluating the plurality of images to determine an optical flow value associated with at least one pixel of at least two images of the plurality of images.

Abstract: In methods of making head assemblies, a ceramic slider having a row of receiving apertures is united with a multiple serial ferrite arch structure shaped in complementary fashion so that successive arches thereof register within the apertures to define erase pole pieces. The face of the resulting assembly is ground flat and parallel to the arch base and the bridges thus formed on the base side may be separated between the arches. The assembly is then bisected along the row of pole pieces into complementary halves, and the facing surfaces are ground and lapped to provide a desired width for the erase member formed by the pole piece half and associated leg of one of the ferrite arches. Grooves are cut into the bisected surfaces at the pole pieces to define the erase track width and the erase gap length for the erase member.
