This paper introduces "Boxcan", an information retrieval platform for aggregated objects in ID-based object management system based on GS1 EPCglobal architecture framework. Boxcan platform receives an EPC of a container, then provides a tree structure of current parent-child relationship between the EPCs of the container and its inner objects. This paper proposes the system design of Boxcan...
Wireless and battery-less health monitoring of machinery and structures have been a dream in mechanical engi-neering. Particularly, simultaneous data collection from multiple sensors is required to detect failure or malfunction before it becomes fatal problem. In this paper, a concept of simultaneous data collection from multiple sensor RF tags with multiple subcarriers is proposed and its feasibility...
Physical objects often form a group such as objects in a shipping container. RFID enables us to identify each object and even the container itself. However, current RFID does not provide information on IDs missing from a group. This paper proposes a method to determine the unique IDs of objects missing from a group without any external database or verifier. The proposed method logically splits a group...
