Abstract: A phytosanitary treatment blockchain is generated from automatically gathered phytosanitary treatment records. The phytosanitary treatment records are generated by matching authenticated treatment data with authenticated identification data. Matching may be based on geolocation, timestamps, or both. Authentication may be based on digital signatures using private key encryption. Separate treatment sensors and identification sensors automatically gather information about a phytosanitary treatment and the item being treated. The gathered information is encrypted and transmitted to blockchain members that perform authentication, matching, and generation of the phytosanitary treatment blockchain. A tracking code may be issued for each treatment. The tracking code is used to obtain an authentication of the treatment that indicates whether the treatment passed or failed.

Abstract: A reconfigurable photonic integrated circuit focal plane array (RPIC-FPA) includes detectors and photonic integrated circuit coupled to the detectors that are configured to mix a return signal beam with local oscillator (LO) beams to produce a combined beam and direct the combined beam to the detectors. The LO beams have reconfigurable optical properties enabled by the RTIC-FPA. The LO beams are individually addressed to switch the detectors between a direct detection mode and various coherent detection modes based on adjustments to the optical properties of the LO beams. In the coherent detection mode, the controller is configured to mix the return signal beam with the LO beam having adjusted optical properties to produce the combined beam, and, in the direct detection mode, the controller is configured to disable the LO beams based on adjustments to the optical properties and to direct the return signal beam to the detectors without mixing.

Abstract: A process is provided for determining the amount of phosphine gas in the atmosphere of an enclosed area that has been fumigated with phosphine (PH3). This process comprises: (A) sampling said atmosphere of said enclosed area to obtain a gaseous sample; (B) selectively removing water from said gaseous sample by passing said gaseous sample through an evaporation zone to obtain a dry sample, wherein said evaporation zone comprises a copolymer of tetrafluoroethylene and perfluoro-3,6-dioxa-4-methyl-7-octene-sulfonic acid; and (C) analyzing said per-evaporated sample in a detector to determine the amount of phosphine gas in said dry sample. The process allows for heretofore unattained capability of monitor measurements of phosphine gas (PH3) up to 1% (10,000 ppm).
