Joint Estimation of Position and Gain for RFID-Tag Assisted Surgery Support System
نویسنده
چکیده
Joint estimation of RFID-tag position and gain is proposed for RFID-assisted surgery support system. Although various RFID-tag positioning schemes have been proposed, gain variations in RFID-tag could affect the accuracy in the positioning. This paper uses a non-linear optimization method to estimate the gain and position of RFID-tag simultaneously. Computer simulation result shows that the proposed scheme is capable of estimating the tag position accurately.

The New Approach to RFID Assisted Navigation Systems for VANETs
In this paper, we propose a systematic approach to designing and deploying a RFID Assisted Navigation System (RFIDANS) for VANETs. RFID-ANS consists of passive tags deployed on roads to provide navigation information while the RFID readers attached to the center of the vehicle bumper query the tag when passing by to obtain the data for navigation guidance. We analyze the design criteria of RFID...
متن کاملA Broad-Typed Multi-Sensing-Range Method for Indoor Position Estimation of Passive RFID Tags
The RFID (Radio Frequency IDentification) system is paid attention as a technology that can realize a ubiquitous environment. Each RFID tag has a unique ID code, and is attached on some object with the information of the objects. A user reads the unique ID code using RFID readers and obtains the information of the object. One of the important applications of RFID technology is the indoor positi...

The authors discussed on the development of a safety management support system to prevent construction site accidents using working area information. The past disasters on heavy equipment were evaluated to clarify the causes of the accidents, and the functions for support system to prevent collision were defined. The design of the system was proposed with working area from RFID technology that ...
متن کاملInfluence of the position of a UHF-RFID tag relative to the antenna in the information reading
The main idea of this paper is to determine the influence of the position and the angle of a tag in the reading of an RFID system, therefore we have developed two different experiments. In the first one, a model with a tag was moved perpendicular to two antennas fixed to a vertical support. In the second one, the same model was moved through two vertical supports with two RFID-UHF antennas each...
