  • Patent number: 9738167
    Abstract: A plurality of projections is arranged in a matrix on the upper surface of the housing of a contactless charging unit (110). When supplying power wirelessly to an onboard power reception device, a beam emission unit in a beam reception and emission unit (120) emits a laser beam progressing along the upper surface of a power transmission unit (170) to scan the upper part of the entire upper surface of the power transmission unit (170). When receiving a reflected beam, the beam reception unit in the beam reception and emission unit (120) sends the results of beam reception to a determination unit. The determination unit determines the presence or absence of a foreign substance supported on at least one projection existing on the upper surface of the contactless charging unit (110) on the basis of the results of beam reception.

  • Patent number: 9639576
    Abstract: A database management system (DBMS) generates a query execution plan including information representing one or more database (DB) operations necessary for executing a query, and executes the query in accordance with the query execution plan. In the execution of the query, the DBMS dynamically generates tasks for executing the DB operations and executes the dynamically generated tasks. The query execution plan includes a plurality of query blocks, which are sets of one or more DB operations. When newly generating a task, the DBMS executes determination processing of simultaneous-task-generation number. The determination processing of simultaneous-task-generation number is to calculate, targeting each of the query blocks, the number of simultaneous task generation, which is the number of tasks simultaneously generatable as tasks for executing the query block. The number of the dynamically generated tasks is equal to or smaller than the number of simultaneous task generation.

    Abstract: According to one embodiment, a memory system is connectable to a host. The memory system includes a first memory, a second memory, and a controller. The first memory stores translation information associating a logical address and a physical address. The second memory stores location information associating the logical address and a location of the translation information. The controller updates the translation information and the location information. After returning from a power supply interruption, the controller starts, at different timing, recovery of first location information and recovery of second location information. The first location information is a part of the location information. The second location information is a part of the location information different from the first location information. The controller executes processing different from recovery of the location information between the recovery of the first location information and the recovery of the second location information.
