  • Patent number: 12442491
    Abstract: A process for establishing vacuum insulation under cryogenic condition and an apparatus compatible with such process are described. When an insulation enclosure filled with high purity CO2 is evacuated to around 100 absolute Pa at ambient temperature, hard vacuum of below 1 absolute Pa may be automatically obtained within the insulation enclosure when temperature drops to around or below ?170° C. This process can be employed to provide vacuum insulation for cold box housing air separation units operated under cryogenic condition.

  • Patent number: 11620835
    Abstract: The present disclosure describes a method, an apparatus, and a storage medium for recognizing an obstacle. The method includes acquiring, by a device, point cloud data obtained by scanning surroundings of a target vehicle by a sensor in the target vehicle. The device includes a memory storing instructions and a processor in communication with the memory. The method further includes converting, by the device, the point cloud data into a first image used for showing the surroundings; and recognizing, by the device, from the first image, a first object in the surroundings as an obstacle through a first neural network model.

  • 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.

  • Patent number: 7943816
    Abstract: The present invention provides arachidonic acid-containing plants and soybeans, and a method of use thereof. The arachidonic acid-containing plant is produced by a process that includes an arachidonic acid producing step in which fatty acid synthetase genes associated with the biosynthesis of arachidonic acid are introduced into a plant to produce arachidonic acid. Thus, plants or soybeans containing arachidonic acid can easily be obtained. Therefore, it is possible to obtain a large amount of arachidonic acid at low cost.
