Abstract: Per-and polyfluoroalkyl substances (PFAS) are destroyed by oxidation in supercritical conditions. PFAS in water can be concentrated and prepared for destruction in a pretreatment phase. Following annihilation of the PFAS in supercritical conditions to levels below 5 parts per trillion (ppt), the water effluent can be used to recover heat, returned to sub-critical conditions, and then released back into the environment.

Abstract: Systems, methods, and apparatus for positioning and/or processing items, such as workpieces. The systems, methods, and apparatus may include or use a linear positioner forming a track. In some embodiments, the linear positioner may include a carriage configured to be driven along the track to a desired position, in response to a signal(s), such as a radiofrequency signal(s), received from a computer, which may be a general-purpose, handheld computer, such as a phone or tablet. In some embodiments, the linear positioner may comprise a shuttle including a motor and a carriage, and may be configured to drive itself as a unit along the track. In some embodiments, the track may include a rack having a linear array of teeth formed by two or more frame sections, such as table sections, coupled end to end, with each support section providing a segment of the rack.

Abstract: Systems and methods are disclosed for tracking user access to an advertisement and user transactions with an electronic commerce computer associated with the advertisement. In accordance with one aspect of the disclosed technology, a transaction tracking computer associates an identifier with each access (e.g., click) of an advertisement. Transactions that occur at the electronic commerce computer that are related to the advertisement will be reported to the transaction tracking server together with the identifier. In one embodiment, if the reported transaction is a duplicate of a previously reported transaction, then the reported transaction is determined to be invalid. In one embodiment, if the reported transaction occurs more than a predetermined amount of time after the time the identifier was initially generated, then the reported transaction will also be determined to be invalid.
