  • Publication number: 20240144507
    Abstract: An information processing apparatus includes one or more memories storing instructions, and one or more processors executing the instructions to acquire a captured image and a distance image, detect an object from the captured image, acquire first distance information indicating a distance to the detected object, acquire a grounding position of the detected object based on the captured image and acquire second distance information indicating a distance to the detected object based on the first distance information and the acquired grounding position.

  • Patent number: 11520745
    Abstract: The number of inter-node communications in inter-node deduplication can be reduced and both performance stability and high capacity efficiency can be achieved. A storage drive of storage nodes stores files that are not deduplicated in the plurality of storage nodes, duplicate data storage files in which deduplicated duplicate data is stored, and cache data storage files in which cache data of duplicate data stored in another storage node is stored, in which when a read access request for the cache data is received, the processors of the storage nodes read the cache data if the cache data is stored in the cache data storage file, and request another storage node to read the duplicate data related to the cache data if the cache data is discarded.

  • Patent number: 7767997
    Abstract: A nonvolatile, sophisticated semiconductor device with a small surface area and a simple structure capable of switching connections between three or more electrodes. In a semiconductor device at least one of the electrodes contains atoms such as copper or silver in the solid electrolyte capable of easily moving within the solid electrolyte, and those electrodes face each other and applying a voltage switches the voltage on and off by generating or annihilating the conductive path between the electrodes. Moreover applying a voltage to a separate third electrode can annihilate the conductive path formed between two electrodes without applying a voltage to the two electrode joined by the conductive path.

  • Publication number: 20080148010
    Abstract: The system design is facilitated by eliminating the increase in data transfer volume of the whole system. In order to facilitate the system design, there are provided an operation unit array, a memory array, a data transfer circuit, and a switch circuit. There are also provided a configuration data management unit for managing the configuration data defining the logical behaviors of the operation unit array, the memory array, the data transfer circuit, and the switch circuit, as well as a state transition management unit capable of controlling the switching of the configuration data. The data transfer circuit includes a control circuit capable of autonomously sorting the data by determining the timing of the data sorting according to the setting included in the configuration data.
