It was my first time to use freelancer, when I published my project, I received a lot of bids to do it. When I started talking with lasantha (Embedded), He understood immediately the project, by the way, he always gave me a support, feedback and how is the best way to solve the requirements. At the end, I got the excellent work. Lasantha and his mates have a very good skills to develop bluetooth 4.0 communication, programming cell phones app, and drawing of final diagram of A-PCB. I sent the A-PCB to my supplier in china, to manufacture it. I received the A-PCB without problem, miniaturized layout, lowest consumption, lasting battery draining, all the requirements were covered. I'm really happy with it. I recommended him a lot.. I'll hope to work with him again..

Auscultation based stethoscopic diagnostic device for cardiac murmur identification

IEEE
In a healthy heart, there is no any abnormal blood flow takes place inside, in addition to the usual blood circulating pattern. However when the valves or tissues inside the heart are in diseased conditions, this usual blood flow pattern gets changed. As a result, abnormal sounds are produced with the normal heart beat sound. These abnormal sounds are known as cardiac murmurs. By identifying the murmur type doctors can diagnose the cardiac pathology related to that particular murmur type. This paper describ

Knowledge on heart patients through stethoscopic cardiac murmur identification for E-healthcare

IEEE
Cardiac murmurs are the sounds produced by the abnormal passage of the blood flow inside the heart due to the diseased valves or tissues. Identifying the type of the murmur can diagnose the cardiac pathology related to that particular murmur. This paper describes a researched digital stethoscope that can be used as a stethoscope as well as a murmur identification device. To capture the heart beat, a chest piece of a traditional stethoscope is used with a condenser microphone attachment. Then the signal is a
