  • Patent number: 11260345
    Abstract: A desiccant wheel is provided to be rotatable. Through the body of the wheel or a surface adsorbent, water vapor in humid air flow is adsorbed. By passing a high-temperature air flow through the wheel, the body or surface coating is regenerated with moisture removed. Along a cross-section radial, the wheel is divided into different areas. The body has three-dimensionally inter-connected pores. The pores can be of different types. The wheel is a complete concentric cylinder or a concentric cylinder comprising equal or unequal sectors. The equal or unequal sectors are separated with each other. The wheel can rotate at a fixed speed for continually repeating a process of adsorbing, transiting, and regenerating. Thereby, drying can be carried out without causing physical or chemical change to heat-sensitive material, which also improves drying efficiency, reduces size, lowers power consumption, and helps in carbon reduction for industry.

  • Patent number: 11120023
    Abstract: A graph processing system for concurrent property graph queries of a property graph implemented in a distributed network computes on respective nodes a subgraph shard represented as edge-sets containing vertices within a certain range. Each node stores data for a subgraph shard that contains a range of local vertices that are a subset of all vertices of the property graph. Each subgraph shard also has boundary vertices having edges that connect the subgraph shard to boundary vertices of another subgraph shard. Upon receipt of concurrent queries of the property graph, a query of the subgraph shards is scheduled in accordance with an initial vertex for each concurrent user query. The property graph is traversed by traversing edge-sets within a subgraph shard on each node and during traversal messaging is used to send values of boundary vertices to at least one other node having another subgraph shard sharing the boundary vertices.
