中文摘要：

在临床的实践，出血性的点(HS ) 的检查仍然保持困难。在这份报纸，我们描述 remote controlled 囊(RCC ) 有一个自动化、基于颜色的传感器的微系统识别并且本地化 HS 胃肠(官方补给) 道。在 vitro，检测传感器测试证明当在 MIF 的 Hb 的集中在 0.05 g/ml 上面时，有或没有血红素(Hb ) 区别模仿的肠的液体(MIF ) 有能力。因此，这个 RCC 系统能在官方补给的道检测 HS 的相对精确的地点。

英文摘要：

In clinical practice, examination of the hemorrhagic spot （HS） remains difficult. In this paper, we describe a remote controlled capsule （RCC） micro-system with an automated, color-based sensor to identify and localize the HS of the gastrointestinal （GI） tract. In vitro testing of the detecting sensor demonstrated that it was capable of discriminating mimetic intestinal fluid （MIF） with and without the hemoglobin （Hb） when the concentration of Hb in MIF was above 0.05 g/ml. Therefore, this RCC system is able to detect the relatively accurate location of the HS in the GI tract.
