  • Patent number: 10540171
    Abstract: A state capture designation for an element of an application within an application design environment may be received, indicating that the application, once deployed, will include a state capture functionality for capturing a state of the element, and a state restoration function for restoring the state of the element. Following deployment of the application within a runtime environment, and in response to an invocation of the state capture functionality, a captured state of the element may be stored. A state restoration request for the captured state may be received by way of the state restoration functionality, and following a re-deployment of the application with an update to the element that was included as part of an update to the application within the application design environment. The captured state may then be restored to the updated element, in response to the state restoration request, and within the runtime environment.

  • Patent number: 10519544
    Abstract: A method for atomic layer deposition of high temperature materials from single source precursors includes placing a substrate in a reaction zone in gas isolation from other reaction zones and contacting the substrate in the reaction zone with a reactant to allow atoms in the reactant to combine with reaction sites on the substrate to form a layer of the reactant on the substrate. The substrate is then placed in a purge zone and purged with a flowing inert gas. The substrate is then placed in a final reaction zone in gas isolation from the other zones wherein the final reaction zone has an atmosphere and temperature to decompose adsorbed reactant and/or form desired phases with crystallinity to form a layer of material. The substrate is then placed in a purge zone and the process is repeated until a layer of material of desired thickness is formed on the substrate.
