  • Patent number: 10776133
    Abstract: Methods, systems, and devices for preemptively loading code dependencies are described. In some systems, an application server—which may be a software component of a user device—may perform a loading process for an application framework module (e.g., based on receiving an execution request for a corresponding application). To reduce the latency of loading the framework module, the application server may perform one or more preemptive non-framework network requests to retrieve code dependencies for the framework or the application code. These requests may be sent prior to the framework loading process, or in parallel with the framework loading process. The application server may receive the code dependencies in response, and may store these dependencies in a memory cache. When the framework loading process needs these code dependencies, the application server may efficiently access the dependencies locally in the memory cache rather than remotely requesting the dependencies over the network.

  • Publication number: 20190331364
    Abstract: A method and a system of a high-temperature calcium looping thermochemical energy storage are provided. A thermochemical energy storage system is based on CaCO3/CaO, and an energy storage is performed by a mutual transformation between a thermal energy and a chemical energy. When solar irradiation is sufficient, CaCO3 solid particulates are indirectly heated by hot air generated from solar energy to perform an endothermic decomposition reaction, and received heat is stored in decomposition products of CaO and CO2 in a form of the chemical energy. When heat is required, a reversible thermochemical reaction occurs between the CaO and CO2 under an atmospheric pressure, and the chemical energy stored in the CaO and CO2 is transformed into the heat for release.
