Accuracy and Electromagnetic Safety Evaluation of a Portable Electromagnetic Localization System for Micro Invasive Medical Devices in Vivo

Aiming at localizing the telemetric capsule for detecting gastrointestinal physiological parameters in vivo accurately,a portable alternating current(AC)electromagnetic localization system is designed.To verify the feasibility of the method,the model and construction of the localization system are detailed.And static and dynamic accuracy of the localization system are tested by experiments.Next,we compare the simulating results of the electromagnetic radiation aroused by the localization system with the electromagnetic safety standards of human(ICNIRP guidelines and IEEE standard C95.1-1991).Finally,in terms of the results of the static and dynamic experiments,conclusions are drawn that the accuracy of portable positioning system is high(less than 10 mm)enough to satisfy the localization need of the micro invasive medical devices in vivo,and there is no harm of electromagnetic radiation to human.

识别TCO显示器小技巧

TCO是全球认证的显示器环保和防辐射质量标准，现在市场上通过TCO标准认证的显示器越来越多。但是很多消费者对如何鉴别一款显示器是否通过TCO标准认证还是不太清楚。一款显示器通过TCO标准认证之后，只是内在品质上发生了很大变化，从外观上看并无很大的区别。如果仔细观察．还是能发现一些不同之处，主要有以下几点。
