  • Publication number: 20220068091
    Abstract: A claw gaming machine may comprise a cabinet, a claw assembly, prize objects, and a shooter unit. The machine may be configured to: determine an outcome of a claw game; allow an input device to control the claw assembly; end the claw game when the claw assembly does not pick up a prize object and the determined outcome is a losing outcome; cause the claw assembly to move and release the picked-up object away from the shooter unit when the claw assembly does pick-up a prize object and the determined outcome is a losing outcome, cause the claw assembly to drop the picked-up object on the shooter unit when the claw assembly picks-up the object and the determined outcome is a winning outcome; and cause a winning game presentation display when the claw assembly does not pick up a prize object and the determined outcome is a winning outcome.

  • Publication number: 20210303596
    Abstract: A DBMS includes a first node and a plurality of second nodes. The first node manages a state of each second node. When a first DB of the first node is updated, the update is reflected in a second DB of each second node. The first node changes a state of each of a fixed number of the second nodes to “retrieval stop” (a retrieval TX cannot be received). When each of the fixed number of the second nodes is not executing the retrieval TX, a reference destination is defined as data in the updated second DB, and the first node changes the state of the second node to “normal” (the retrieval TX can be received). When the retrieval TX is received, the first node allocates the retrieval TX to the “normal” second node.

  • Patent number: 11080545
    Abstract: A computer-implemented method for increasing a recognition rate of an optical character recognition (OCR) system is provided. The method includes preprocessing by receiving an image, and extracting all vertical lines from the image. The method includes adding vertical lines at character areas of the image, extracting all horizontal lines from the image, and creating an unlined image removing all the vertical/horizontal lines from the image. The method further includes determining a border of a vertical direction of the unlined image based on the total of pixels of rows in each column, and adding vertical/horizontal auxiliary lines between characters of the unlined image. The method also includes postprocessing by receiving garbled words of OCR output, removing noise after morphologically analyzing, replacing garbled letters with correct ones based on a frequent edit operation, and outputting the correct word, weighting results of image distance calculations based on machine learning.

  • Patent number: 11074271
    Abstract: A database management system (DBMS) performs, in response to a conversion request to convert a store format of a table in a database, a process (base type change process) for changing a store format indicated by information (base type) indicating the store format of the table to a store format according to the conversion request, and performs a data conversion process asynchronously with the aforementioned process. In an import process after the base type change process, the DBMS imports, into the table, a chunk in the store format indicated by the base type after change. In the data conversion process, the DBMS converts a chunk in a store format different from the store format indicated by the base type into a chunk in the store format indicated by the base type.

  • Publication number: 20200355511
    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.

  • Publication number: 20200265050
    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: 10747773
    Abstract: A database management system (DBMS) manages a database existing in a second storage device with an access speed lower than that of a first storage device. In an execution of a query, the DBMS dynamically generates tasks two or more executable tasks in parallel. The DBMS generates task start information which is information representing a content of the execution of the task, manages the task start information, and executes a content represented by the task start information by the task. The task start information includes a data address set existing in the second storage device. The DBMS controls movement of the data address sets between the first storage device and the second storage device based on a management state of the task start information. In addition, the DBMS selects the task start information based on whether or not the data address set exists in the first storage device.
