  • Patent number: 7610311
    Abstract: A method for quantifying plant resource using a GIS is disclosed, in which it is possible to more efficiently quantify plant resources with less manpower, time and cost using a GIS when quantifying plant resources in a certain region. In the method, a sample group is extracted from mother groups having a plurality of distribution maps having a plurality of environment factors including IMI as attribute data, the IMI being obtained through a GIS preprocess. A relative model formula is obtained between a plant resource real measurement value of the sample group and an environment factor real measurement value and is related with the distribution map of the mother group, and the distribution maps are overlapped for thereby forming a plant resource estimation distribution map of the mother group.

  • Patent number: 7447180
    Abstract: The present invention is a wireless media access method on a wireless network synchronized by a synchronizing signal broadcasted from a coordinator. In the method, priority is assigned to a plurality of devices interconnected over the wireless network for securing wireless resources in accordance with application characteristics of a packet to be transmitted, and if the devices request communication, dividing at least one slot within a superframe into a plurality of minislots. Minislots are then allocated to the devices, respectively, according to the priority, and information about the allocated minislots is inserted into the synchronizing signal. The information is then broadcast, thereby allowing each of the devices with the allocated minislots to exclusively use the allocated minislot for data communication.
