    摘要: A high-efficiency, motorless purge system for closed-cycle absorption heat pumps, adapted for both absorption heat transformers and absorption chillers, using a series of valves to control the entry and exit of absorbent solution into a low-pressure, secondary absorption vessel. A small percentage of the total circulating solution is forced under pressure into the secondary absorption vessel via a spray nozzle, causing adiabatic absorption of absorbate vapor by the solution. Non-condensable gases accumulate in the secondary absorber until a certain vapor pressure is reached, upon which, gas, and possibly liquid, are transferred to an exhaust vessel having an exit vent for non-condensable gases. In an absorption chiller system, the secondary absorber has an internal heat exchanger to lower the temperature of the solution within, to facilitate the absorption process.

    摘要: The present invention provides a vapor-permeable flexible sensing platform unit comprising: a first porous membrane, wherein said membrane is substantially flexible and hydrophobic; and a volatile organic compounds (VOCs) sensor disposed on said membrane, the VOCs sensor comprising an electrode array and a conducting polymer porous film being in electric contact with said electrode array, wherein the VOCs sensor is insensitive to lateral strain. Further provided are a method of preparation of said platform unit and a lift-off, float-on (LOFO) method for the preparation of protonically doped polyaniline (PANI) thin films.

    摘要: Systems and methods are provided for moving replicas of a target data object between a plurality of storage nodes that store multiple replicated data objects, by setting new applications to a move mode, waiting for prior applications to exit before moving the target data object, determining that an indication of access to the target data object is done, and responsively copying the replicas of the target data object from first locations among the plurality of data storage nodes to second locations among the plurality of storage nodes.
