International Classification:

US Classification:

Abstract:

A method for establishing and maintaining a wireless ad hoc network comprising backbone nodes which forward packets through the network and non-backbone nodes which are capable of using the network, but do not forward packets. Signaling packets containing one or more protocol support records are periodically generated and transmitted by each node to neighboring nodes and are forwarded through the network by backbone nodes. Non-network nodes are initially selected to become backbone members during a SELECTION process based on an assessment of the nodes connectivity relative to its neighbors. Link quality between nodes is monitored and used during an EXPANSION process in which additional non-network nodes may become backbone members. Disconnected backbone segments are interconnected during a CONNECTION process and the network is maintained during a MAINTENANCE process by periodically assessing the value of a backbone nodes membership in the backbone. Efficient multicast routing is supported over the backbone by dynamically establishing and maintaining multicast trees.

Abstract:

A database management and synchronization program implemented across a peer-to-peer computer network, consisting of a sharing community of user computers. Database record synchronization throughout the sharing community is accomplished by using a synchronization object which contains the information about a change in a specific record or the addition of a new record. The synchronization object is transmitted by a local user computer at any time to a routing agent, which in turn transmits the synchronization object at any time to remote user computers within the sharing community. The synchronization object is then used by the remote user computer to update their database records.

Abstract:

The method for determining property feature segmentation includes: receiving a region image for a region; determining parcel data for the region; determining a final segmentation output based on the region image and parcel data using a trained segmentation module; optionally generating training data; and training a segmentation module using the training data S
