摘要： A tightly coupled fusion approach that dynamically consumes light detection and ranging (LiDAR) and sonar data to generate reliable and scalable indoor maps for autonomous robot navigation. The approach may be used for the ubiquitous deployment of indoor robots that require the availability of affordable, reliable, and scalable indoor maps. A key feature of the approach is the utilization of a fusion mechanism that works in three stages: the first LiDAR scan matching stage efficiently generates initial key localization poses; a second optimization stage is used to eliminate errors accumulated from the previous stage and guarantees that accurate large-scale maps can be generated; and a final revisit scan fusion stage effectively fuses the LiDAR map and the sonar map to generate a highly accurate representation of the indoor environment.

摘要： An anti-counterfeit authentication system provides authentication services over available communication networks. The system assigns unique anti-counterfeit certificates to authentic items. The certificates are stored in anti-counterfeit tags that are attached to the authentic items. An authentication server provides authentication services to authentication clients over the communication networks. The authentication clients read, via tag readers, the anti-counterfeit certificates from the tags associated with items to be authenticated, provide the anti-counterfeit certificates to the authentication server which determines authenticity and supplies authentication results back to the authentication clients.
