Abstract: Technologies are generally described for methods and systems effective to secure process synchronized requests after at least one secure inter-device communication link between the originating and confirming communication devices is established. A method may include forwarding, by the confirming communication device the request and receiving, by a server, a first request from the originating device and at least one second request from the confirming device. The method may also include, by the server, determining a sequence of receiving of the first and the at least one second requests and processing the requests in order to authenticate a communication device, accept or reject a financial transaction, based on the receiving sequence and receiving time difference.
Abstract: The method and system for correcting motion-induced phase errors in Magnetic Resonance Imaging (MRI) use a phase shift of the non-phase encoded reference echo-signal accumulated during the diffusion-weighting in order to characterize bulk motion and tissue deformation and to compensate their effect for correcting the diffusion/perfusion-weighted image. The sequences unbalanced with respect to the first motion derivative are used for distinguishing the perfusion component. The MRI apparatus provides additional excitation resonance-frequency ranges for forming the reference echo signals.
Abstract: The invention relates to a radiant energy powered water heating methods and apparatus, particularly, to the open-loop solar radiation collection systems. At least one nozzle is directed against a reflection surface facing an evaporation surface to spray at least one jet with reflection to diffuse the fluid within the inner cavity in an atomized plume having the evaporation surface been moisturized by a part of the sprayed fluid and said moisturizing part of the sprayed fluid been sufficiently vaporized or evaporated (see FIG. 3).
