Introduction of embedded:
Embedded system debugging involves more conceptual layers of a target system than debugging for time-sharing systems. Consider the case of debugging a C program within a time-sharing system. User-debugger interaction occurs almost entirely at a C language level of abstraction. Descent into assembly language and machine code representations of a target program is rare. Suspicions about a compiler bug may require inspection of generated assembly code
Biomedical engineering has only recently emerged as its own discipline, compared to many other engineering fields. Such an evolution is common as a new field transitions from being an interdisciplinary specialization among already-established fields, to being considered a field in itself. Much of the work in biomedical engineering consists of research and development, spanning a broad array of subfields (see below). Prominent biomedical engineering applications include the development of biocompatible prostheses, various diagnostic and therapeutic medical devices ranging from clinical equipment to micro-implants, common imaging equipment such as MRIs and EEGs, biotechnologies such as regenerative tissue growth, and pharmaceutical drugs and biopharmaceuticals.
This paper presents the hardware overview, design and implementation of a fully wireless ambulatory multi-parameter monitoring system. Here we measure the respiration rate. In respiration circuit development, this system is capable for providing both Piezo film sensor and accelerometer signals to estimate respiration signals. These signals have been filters at 0.1Hz and 2 Hz for noise reduction. The values from these sensors are given to ADC. The Microcontroller processes the sensor values received from the ADC. This signal is then given to the RF module for transferring of data for user reference to another Micro controller kit.
