  • Publication number: 20150026293
    Abstract: A method, an apparatus, a terminal, and a server for synchronizing a terminal mirror are provided. The method includes: obtaining, by a terminal, multiple input events during running of application software; aggregating the multiple input events to obtain an aggregate event; and transmitting the aggregate event to the server, so that after parsing the aggregate event to obtain the multiple input events, the server processes the multiple input events by using a virtual machine that is of the terminal and set on the server, so as to obtain user data generated during the running of the application software. In the present invention, the terminal transmits the input events to the server in an event-driven manner, so that the server obtains the user data that is the same as that on the terminal that runs the application software, thereby ensuring that the server can back up complete user data.

  • Patent number: 8071007
    Abstract: The invention relates to the use of Fused Deposition Modeling to construct three-dimensional (3D) bioresorbable scaffolds from bioresorbable polymers such as polycaprolactone (PCL), or from composites of bioresorbable polymers and ceramics, such as polycaprolactone/hydroxyapatite (PCL/HA). Incorporation of a bioresorbable ceramic to produce a hybrid/composite material support provides the desired degradation and resorption kinetics. Such a composite material improves the biocompatibility and hard tissue integration and allows for increased initial flash spread of serum proteins. The basic resorption products of the composite also avoids the formation of an unfavorable environment for hard tissue cells due to a decreased pH. The scaffolds have applications in tissue engineering, e.g., in tissue engineering bone and cartilage.
