  • Publication number: 20250084805
    Abstract: The provided is energy storage method and device for biomass cascade pyrolysis coupled with new energy power generation. The key point of the technical solution is that, with inexpensive, clean and safe biomass as energy storage medium, the redundant unstable electric energy is converted by a cascade pyrolysis energy storage system into an easy-to-store liquid and solid chemical energy in biomass pyrolytic products, and based on use requirements, can be further converted into clean fuels for power generation or exported renewable chemicals, so as to realize continuous stable output of the new energy power generation systems. Furthermore, the cascade pyrolysis energy storage system can, based on the principle of “energy level matching”, fully recover and utilize the electric energy, high-temperature heat energy and low-temperature heat energy generated in pyrolysis processes, thereby maximizing the energy utilization efficiency of the system.

  • Publication number: 20250050503
    Abstract: Disclosed in the present invention are a control system and method for guiding classified storage and feeding/discharging takeout and placement of lock pins. The control system for guiding classified storage and feeding/discharging takeout and placement of lock pins comprises a terminal operation system, a guide system, a robot system, a feeding and discharging device, a transportation unit, and a stacking storage unit. The terminal operation system acquires terminal operation information in real time, and transmits, to the guide system, information of containers needing to be unloaded and loaded and information of corresponding lock pins.

  • Patent number: 7752225
    Abstract: Techniques for migrating duration trees from a source database server (or instance) to a destination database server (or instance) are provided. A duration is a memory management construct that allows database components to group related areas of memory together. A source duration tree is captured at the source database server and combined with a destination duration tree at the destination database server. Any duration identifiers in the source duration tree that conflict with (i.e., are the same as) a duration identifier in the destination duration tree are mapped to new duration identifiers.

  • Patent number: 7634512
    Abstract: A technique for migrating (e.g., “copying” or “moving”) temporary data from one session to another session is provided. While executing a workload associated with a particular session, session state is created. A subset of the session state comprises large objects that are referred to as “temporary data.” Thus, temporary data is stored in a database (instead of in the database server) and is normally deleted when the particular session is deleted. To avoid this deletion when the session state is migrated to a different session, the temporary data, in one embodiment, is saved in an external storage that is separate from the database. An external table is created in the external storage and stores the temporary data. Location information to access the external table is provided to the other session.
