摘要:
Provided is a k-nearest neighbor search method of searching for a query number k of nearest points to an arbitrary point in a DBMS for creating a spatial index from multidimensional points, comprising setting a search conditions, judging which of a lowest branch and an intermediate branch of the spatial index a nearest region to the query point is, calculating, when the nearest region is judged to be the lowest branch, a distance between the query point and a child region of the nearest region, storing information of a divided region which has become a calculation target, calculating, when the nearest region is judged to be the intermediate region, a distance between the query point and a point included in the nearest region, storing information of the point which has become a calculation target, finishing search processing when the search conditions are satisfied, and obtaining a search result from the DBMS.

A crop traceability system includes: a terminal which moves together with a machine to harvest or transport a crop; and a server which receives an information from the terminal. The terminal includes: a location information acquisition unit which acquires a location information of the terminal; and a transmitter which transmits the location information and a machine ID of the machine to the server. The server includes: a storage unit which stores a location information of a planimetric feature; a receiver which receives the location information and the machine ID which are transmitted by the terminal; and an ID information processor which links the machine ID with a planimetric feature ID of the planimetric feature when a location information of the planimetric feature stored in the storage unit coincides with the location information transmitted by the terminal.

The present invention aims to provide a system that automatically shows multiple fertilization design patterns suitable for the soil and crop, in linkage with map data and in accordance with fertilization design conditions each including a different fertilizer pattern and priority condition so as to allow the user to compare the multiple fertilization patterns on the same screen. The system includes units configured to receive designation of an agricultural field on the map, then to receive a fertilization design condition including a fertilizer pattern and a priority condition, to design fertilization patterns for the agricultural field, and to display the designed fertilization patterns on the same screen.
摘要:
Positional information transmitted from a mobile unit mounted on an agricultural work vehicle is displayed overlapping with map data obtained from a map database. Display of the field data on the display screen is color-coded based on a result of comparison of a date of the positional information transmitted from the mobile unit with the field data obtained from the map database and a scheduled date for work stored in the field data. Thereby, an operational management system of an agricultural work vehicle capable of promptly and spatially confirming an operational situation of the agricultural work vehicle is provided.

There is provided a firmware updating technique for which consumed memory and writing time are small for devices subject to a firmware update, for which the distributed update size is small, and which is performed via a broadcast network. To this end, assuming that the latest firmware version is N, there is provided a means that extracts differences between firmware of version j-i and firmware of version i (j−1→j differences) for j=2 to N, and that distributes these differences together via the broadcast network. With respect to a device subject to an update comprising firmware of version i, there is provided a means that saves, of the distributed j−1→j differences (where 2≦j≦N), only the differences for which j

There is provided a high-speed firmware update method which reduces the burden on a firmware developer. A server is installed which is provided with a function of receiving an image of new-version firmware (a new firmware image), comparing it with an image of old-version firmware (an old firmware image), taking out only updated files, and creating a procedure for updating the old firmware image to the new firmware image and an update image configured by update data.
摘要:
A technique for updating a piece of firmware in an information processing device includes a remote management section for communicating with a server device storing a piece of software to be distributed and a controlled device within a home network and managing an application, a service management program for managing a service of the controlled device, a firmware management program for managing a piece of firmware of the controlled device, a gateway firmware management program for managing a piece of firmware of the gateway device, a gateway firmware updating program which rewrites the piece of firmware of the gateway device, and a dependence relationship management program which analyzes a dependence relationship aggregation table obtained by aggregating the contents of a dependence relation table describing a piece of software on which the piece of software to be distributed depends.
摘要:
To provide a retrieval space map in which the ratio of unnecessary files included in the retrieval result can be decreased. One or more retrieval object spaces (retrieval objects) in which a file suitable for a retrieval purpose exists at high possibility are predefined according to the retrieval purpose under a condition containing a number of retrieval objects, and the space in which a necessary file exists at high possibility can be searched by designating the retrieval object to be suited for the retrieval purpose at the time of retrieval.
摘要:
The firmware update apparatus is configured so that data required for update is accessible from both of normal firmware and emergency firmware and is provided with a section which sets the next-time boot destination to the emergency firmware during update, a section which saves a file before update into an area originally occupied by an update file, a section which inspects that a file required for booting the normal firmware is not broken or confirms that activation is actually possible from a virtualized environment, during activation of the emergency firmware, a section which restores the state before update by the saved files before update and a new update procedure automatically generated by reversing the contents of operations of the update procedure, and a section which, for each update file, describes a necessary reactivation target in the update procedure.

An unauthorized access detection device that includes a control device for executing: abnormal access request detection processing in which a plurality of pieces of input/output request data for accessing a file is acquired and it is determined whether or not an access mode to the file is abnormal on the basis of patterns of the acquired plurality of pieces of input/output request data; abnormal data detection processing in which, where it is determined that the access mode to the file is abnormal, it is determined, by specifying data to be written into the file on the basis of the acquired input/output request data and specifying a trend of the specified data, whether or not the specified data is abnormal data; and suspicious process resolution processing in which, where it is determined that the specified data is abnormal data, predetermined processing related to access to the file is executed.
