  • Publication number: 20230210540
    Abstract: Systems, methods, and devices for treating vascular defects are disclosed herein. In some embodiments, a method of treating an aneurysm includes positioning a distal portion of an elongated member near or within an aneurysm. The method can include introducing an embolic composition into a lumen of the elongated member using an injector device coupled to a proximal portion of the elongated member. The injector device can pressurize the embolic composition to a pressure of at least 10,000 psi. The method can also include delivering the embolic composition into the aneurysm via the elongated member.

  • Patent number: 11644324
    Abstract: The present invention identifies a danger spot effectively. In a navigation device 10, a danger spot identification unit 34 identifies a jump-out danger spot on the basis of past information which is acquired by a past information acquisition unit 24 and indicates a situation of a jump-out accident in the past, and surrounding information which is acquired by a surrounding information acquisition unit 32 and indicates a surrounding situation of a vehicle. Here, the past information includes surrounding facility identification information (information related to an identification planimetric feature) used for identifying a jump-out danger spot and information related to a jump-out object. As a result, the danger spot identification unit 34 can identify a danger spot of a jump-out which can occur due to a planimetric feature (a facility) in a jump-out accident. Therefore, the navigation device 10 can identify a jump-out danger spot effectively.

  • Patent number: 11494383
    Abstract: When a DBMS receives a suspend instruction in which a suspend completion time of query processing is a future time and between receipt of the suspend instruction and the suspend completion time, if there is a target object (at least a processing object whose execution is in progress upon receipt of the suspend instruction) whose predicted completion time is at or precedes the suspend completion time, the DBMS changes the state of the target object to a state signifying a snapshot suspend. If there is a processing object whose state signifies a snapshot suspend, the DBMS executes the processing object at or before the suspend completion time.

  • Patent number: 11321302
    Abstract: A computer system according to the present invention has a plurality of processor cores that execute a plurality of threads in a parallel manner. When one of the threads updates a database (DB) region that is among a plurality of database regions associated with a database (DB), and that cannot be updated by more than one thread, the computer system selects one of one or more dedicated log buffers as a log buffer to which a log relating to the update of the database region is to be written. In contrast, when one of the threads updates a database region that is among the plurality of database regions, and that can be updated by more than one thread, the computer system selects one of one or more shared log buffers as a log buffer to which a log relating to the update of the database region is to be written. Each dedicated log buffer is a log buffer that can store one or more logs associated with only one thread and that cannot store two or more logs associate with two or more threads.
