摘要:
A memory management apparatus for use in an open geographic information system includes a plurality of layers, each layer requiring a layer component, a disk buffer management component, a memory buffer management component and a spatial index management component; a layer collection component having a plurality of layer components, each layer component containing responsibility of managing all of the spatial data included in one layer accessed thereto through a data provider component; and a total memory management component. In the system the total memory management component manages totally a memory buffer to spatial data included in one or more layers, allocates a corresponding memory if each of memory buffer management components requests a memory buffer and frees a memory of a predetermined memory buffer management component when an available memory lacks.

The present invention relates to a system and method for tracking the position of a moving object. A system for tracking the position of a moving object includes: WSNs composed of a plurality of sensor nodes, each generating connection release information representing that the connection between the corresponding WSN and a moving object having a moving node serving as a sensor node attached thereto has released if having perceived the departure of the moving object; base stations managing the plurality of WSNs and collecting position information on the plurality of sensor nodes; a node information database storing the position information on the plurality of sensor nodes collected by the plurality of base stations; middleware checking the current position information on the moving object stored in the node information database if receiving the connection release information through any of the plurality of base stations, and deleting the current position information on the moving object stored in the node information database if the checked current position of the moving object is in a WSN having perceived the departure of the moving object; and a moving-object tracking application provided with the position information on the moving object by the middleware to track the position of the moving object. According to the present invention, it is possible to efficiently process information of a WSN managed by each base station in middleware managing a plurality of base stations, thereby improving the accuracy in tracking the position of a moving object.

The present invention provides a washing machine and method of controlling a drying cycle thereof, by which a laundry can be evenly distributed within a drum rotated at a second speed for a low-speed dewatering cycle during the drying cycle to further enhance a drying effect. Once the drying cycle is initiated, a blower fan and heater are driven to circulate hot air within the washing machine via tub and circulation duct. And, the drum is rotated by applying a first rotational speed for a normal drying cycle and a second rotational speed for a low-speed dewatering cycle with a prescribed duty ratio.
