The state-of-the-art capsule endoscopy (CE) technology offers painless examination for the patients and the ability to examine the interior of the gastrointestinal tract by a noninvasive procedure for the gastroenterologists. In this work, a modular and flexible CE development system platform consisting of a miniature field programmable gate array (FPGA)(More)
In this paper, we propose an efficient algorithm for localization of underground miners using RSSI and ZigBee. RSSI is widely used to measure the distance in wireless system. However, there are possible interferences that may affect the result of measurement, such as propagation, reflection, etc. In this paper, we develop an algorithm that can increase the(More)
Wireless capsule endoscopy (WCE) plays an important role in the diagnosis of gastrointestinal (GI) diseases by capturing images of human small intestine. Accurate diagnosis of endoscopic images depends heavily on the quality of captured images. Along with image and frame rate, brightness of the image is an important parameter that influences the image(More)
In this paper, a design of a microcontroller based Wi-Fi adapter for medical application is proposed. The adapter will enable data logging from an implantable biosensor directly into a Smart device, laptop, or servers connected with hospital's Wi-Fi network. This will allow medical doctors to analyze important physiological data in real time from a remote(More)
