Blood flow, vein and nerves detector using an NIR sensor with RLS estimation for embedded signal processing

In recent years vein and nerve identification is most important role in medical field. Vein and nerve finding used for anesthesia injection during the major surgery. Nowadays doctors use manual method to find these vein, artery and nerve and they inject the medicine. Suppose they inject wrongly it will lead to major health disorder in children's and adults. So the proposed automatic detector was used. NIR (Near Infrared) technology based automatic detector is an advanced one to detect the blood flow, vein and nerves. This technique includes to sense, signal conditioning and ADC (Analog to Digital Converter) to sample electrical signal into digital values for further processing. Sensor signal was given to the LPF (Low Pass Filter) section and get the filtered output. Controller was used to verify the output signal and display the output in both LCD and LEDs. This simulated output was verified with both software and hardware.
