The client system transmits, to the authorisation system, a refresh request for a second grant token for identifying the client system at the authorisation system, wherein the refresh request is transmitted based on the expiry time of the first grant token; and receives the second grant token at the client system, in response to the refresh request.

Abstract: A computer-implemented method for managing a secure data item that is jointly accessible by the first user and the second user. In the method a first system receives a data request comprising an instruction to transmit the secure data item to a second system. The first system identifies that the secure data item is jointly accessible by the first user and the second user, and in response transmits an authorisation request to the second user device. The authorisation request comprises a prompt for the second user to authorise the data request. The first system receives a grant message indicative of the second user granting the authorisation request and in response transmits the secure data item to the second system. The secure data item is prevented from being sent to the second system, if the grant message is not received.

Abstract: A salt composition for use as a fuel in a nuclear reactor is provided. The salt composition can include carrier salts having mixtures of one or more chloride salts or one or more chloride salts and one or more fluoride salts and fuel salts including one or more chloride salts. The carrier salts can include alkali and/or alkaline earth cations, while the fuel salts can include actinide cations. The salt composition has a lower melting temperature, less corrosive redox properties, and allows proliferation-safe retention of actinides and concurrent removal of some fission products, as compared to other salts employed in molten salt reactors. Optionally, the salt composition can include one or more metal halides for further decreasing the melting point and/or increasing the boiling point of the composition, thereby increasing the range of the liquid phase of the salt composition.

Abstract: Methods and systems for three-dimensional imaging through turbulence such as produced by the Earth's atmosphere are described. A first light source may direct an output of pulses to a target through atmospheric turbulence. A first image sensor, for example a time of arrival sensor or focal plane, may receive light from the first light source and may be used to record two-dimensional images or image slices of the target. A second light source may also be used. A second image sensor may receive light reflected from the target. An atmospheric point spread function may be derived or calculated by a means for multiframe blind deconvolution from one or more images of the target received at the second image sensor. The point spread function may be used to deblur or improve the resolution of each of the two-dimensional image slices from the first image sensor. The two-dimensional image slices may be combined to form a three-dimensional image of the target.

Abstract: A closed-loop control system for recycling products, such as food service ware. The system provides a “pure” stream of the products without major contaminants, which facilitates efficient re-fabrication of the product. The system includes collecting the used product from a selected group of users, isolating the used product from other waste, and delivering the product to a reprocessing center. The used product is washed and pelletized to form recycled pellets, which are combined with virgin pellets in ratios conforming with FDA regulations, to produce new recycled products. These new products are then sold back to the group of users, thus maintaining the system in a closed-loop. The recycled products may include plastic materials, such as polystyrene, polyethylene terephthalate, polypropylene, or high density polyethylene. When any of the above-mentioned plastic materials are in their expanded foam state, the system may be more economically feasible to operate.
