My project is finished, but already I have ideas for the future development. The most obvious option for development is the smart phone app. The system will vastly "smarter" to using the ICTs: real time control by the coaches, emergency operation, database of records etc. The cost and size of additional circuits can be reduced by SMD technology. The total cost can be reduced and profitable by using high-volume production. It may be necessary the waterproof material of clothes. The further develo ...
The bicycle accidents and injuries have number of reasons: for example the lack of protective equipment; inappropriate speed for the road conditions; abuse of alcohol and drug; and - unfortunately - the inadequate visibility. The main feature of my project is the Fuzzy logic based visibility system. What is the Fuzzy logic? In contrast to the binary (yes-no) logic, there is not sharp boundaries in the Fuzzy logic. A typical fuzzy sets shown below: There is a variable (e.g. temperature, ...

(Complete list of all blog entries in this series) As I already mentioned in my last post, I did not achieve all my original goals for this project. I'm not sure how this affects the outcome of the challenge, but SkiMon should also satisfy a personal need. So I would like to outline what my personal vision for this project is, what I see as next steps for continuing with development and where I see it finally. Shrinking the hardware SkiMon as it is now is still too large to be easily usable. Wh ...
The following devices are needed for the ECG measurement: AD8232-EVALZ board, 3 pieces of gel ECG electrodes, 3 pieces of ECG adapters, 3 pieces of jack plugs, wires, flexible material for the chest strap, microcontroller. Several options have been for the electrode placement. The one of point is the left and right arm, but I rejected this case, because the distance from the heart is greater than the in other options. Receiving of bioelectric signal is better, if measured on the torso a ...

The contraction and relaxation of the heart muscle are controlled by the self-forming and impulse conduction system located in the heart, which is related to the central nervous system through external innervation. The cardiac muscle stimulating electrical pulses start from the right atrium wall of sine knot,  and getting  the atrioventricular bundle through the atrial muscle wall, which is situated in the lower part of the right atrium, directly above the chamber. The atrioventricul ...

The (Actual) Final Entry

Posted by quisss May 7, 2015
I know I said my last post was the final one, but I decided to write one more summarizing some of the decisions I made, and what makes the Real Time Coach Athlete Monitoring System so great.   The first critical decision that I made was to make this work with a large number of athletes rather than just one. This was largely due to the fact that while some sports are individual, many of them consist of a team with a number of athletes that each need to be monitored. This was something that ...

The Final Entry

Posted by quisss May 7, 2015
It has been a long run, but this will be the final blog post for Real Time Coach, and it's going to be a long one.   First the hardware had to be assembled. As you can see in the pictures below, there is an arduino board with a wireless shield running the entire unit, with the heart rate monitor providing the amplified heart beat waveform. There is also an accelerometer which you can see in the second picture, attached to the multicolored jumper cables. I unfortunately ran out of time to a ...
In this post I finish the presentation of components of used equipments. Arduino: Compared to the other Arduino boards, the Arduino Micro was the best choice for the smart clothes. It is based on the 8-bit ATmega32u4 microcontroller with 16 MHz clock speed. It has 12 analog inputs and 20 digital input/output pins of which 7 can be used for pulse-width modulation (PWM) outputs. After the filtering, the PWM output can be operated as analog output. The amount of available memory is 32 KB. I ...
One more measurement feature that I added to the main unit is an electroencephalogram (EEG) module.  The EEG module is mounted on the helmet and uses two active electrodes placed mounted on the sides of the helmet so that they touch the head skin above the ears and one common mode sense electrode mounted on the front inside the helmet, so that it touches the forehead.   The common mode settling time after the helmet is placed on the head is about 2-3 minutes, so any meaningful EEG ...

(Complete list of all blog entries in this series) This is probably the second-to-last article about my project, on the last day I will try to upload a video showing how it all works together. On the weekend I went ahead and finally  put together all the parts that lived on the different breakout boards for the last few months. I had ordered some new smaller batteries in the meantime, so I went ahead and looked for a new enclosure too. But the first task was to mount the ADXL board on to ...
Here is another update on my "Wearable Sudden Impact and Health Monitor" project.   In this update I will show how I added a measurement feature for body temperature.   The body temperature is measured using the Analog Devices ADT7320, which is very small (4mm x 4mm) and it is mounted on the front inside the helmet, so that it touches the forehead.  To ensure good contact with the skin, the ADT7320 sensor is placed on a layer of elastic sponge-type material.  This implement ...
