2. 2 Electromagnetic Properties Testing the EM properties of the device would be done using an inductive antenna and an oscilloscope A spectrum analyzer would be more effective however there is not one at the disposal of the group As the device is running enclosed within its case the probe perhaps with a small coil attached to the end could be moved around the outside and the oscilloscope checked for any signals Conversely a function generator could be used to attempt to send signals into the device while checking to see if they are being received anywhere inappropriately 3 Microcontroller Testing The testing of the sensor controllers involves both testing the correct transmission and reception of data from the sensors but also testing the electrical properties of the circuit to ensure that it is properly isolated from the power source The method of testing the former is to transmit some known constant value and check if that value was received sensors themselves were tested in this way to determine if they required calibration test controllers themselves test code was written into another microcontroller that output a constant or functional binary value This microcontroller was then connected to the sensor controller as if it were a sensor The received value was then output to a serial monitor and compared to the expected value In nearly all tests the values matched precisely over the entire range

SMART Monitor Infant Smart Monitor Fall 2013 Spring 2014 End of Project Documentation Infant Smart Monitor I Smart Monitor Joseph Cacioppo Duaa Salah Daniel Schmidt Mahsa Shadmani Vasiliy Warkentin May 5 2014 Abstract Monitoring the vital signs of a newborn is a fundamental component of modern healthcare Monitoring can however bring its own problems that are very stressful for both infant and parents These problems arise from the fact that a human is currently needed to do the monitoring This individual must be well trained and diligent in order to be effective Effective data collection is obviously vital to ensure that nothing important was missed and that the readings are accurate Because detecting medically significant events is often a matter of comparing data values to certain thresholds an electronic device could easily accomplish this This paper documents the design of such a device the I Smart Monitor It details the design process in two stages First the documentation supporting the development of a laboratory prototype that includes the motivation for the project as a solution to a societal problem Secondly the development of a deployable prototype and a discussion of what was learned during the first stage and how this was applied The testing procedures that were performed in order to determine if the device meets established criteria are then outlined How these criteria were established and what was lea

7. V _ CREATION DETAILS FALL 2013 Initially this project was focused on a sensor specifically a sensor that would give an early indication of infant jaundice This would have been a device that took a measurement of transcutaneous bilirubin levels processed this data and then displayed it in an easy to understand fashion This idea was scrapped as the team realized that it would be unsuitable for the intended scope of the project This device would have been utterly dependent on the ability to make a proper transcutaneous bilirubin measurement This involves complex physics concepts and fine calibration of LED emission wavelengths which were judged to be insurmountable problems at least within the time allotted After discussion with advisors the project definition was modified and generalized to focus on the interface with the sensors rather than the sensors themselves This has proven to be a very advantageous decision as the new project has been much more suited to the team members skill sets In addition to the design of the I Smart monitor Team 6 was involved in the Idea to Product competition a state wide event for bio medical engineering student projects The competition itself consisted of a presentation of an idea and the marketing strategies involved in deploying the product Upon entering our team acquired two business students to assist in the presentation and the development of our marketing strategy The

Previously the alarm code was simply sending a text indicator of an alarm condition to the Arduino IDE s Serial Monitor window which was used for proof of concept Instead of calling an internal function of the Arduino s Serial class the code now calls the alarm function developed by the I Smart Monitor team In addition to a real time indicator the alarm affects the data being recorded as well This ability is crucial and is obviously dependent on the functionality of the Event Data Recording system In fact this is what is meant by event recorder Ideally the alarm could also give indications about the overall health of the monitor and to do this it would need to be able to receive indications from other features such as the SD card used in the Event data logger D Home Network Connectivity As stated earlier in the Home Network Connectivity feature section the Smart Monitor needs to follow the standards approved for medical devices The Arduino YUN microcontroller fully supports all required specifications However based on our test results making a connection to the internet with the chosen microcontroller was not very simple for people with a low level of technical knowledge So we decided to prepare and write a more detailed user manual for the device to make the connection to the internet easier to understand for our users Above all and because the Home Network Connectivity feature is one of the

SD card will be created based on the sensor type and the serial number The serial number is the first byte and most of the second byte 15 bits of the data packet The MSB of the second byte contains an alarm bit that is used to activate the alarm when SD capacity reaches 80 and when EEPROM capacity reaches 100 After data is stored to the SD card it will be transferred to the internet The remote access feature depends on the event and data logger feature From this we can see the integration of the event data logger feature C Alarm The alarm is closely connected to both the Modular and Event Data Logger features Sensor side the alarm condition is detected by the sensor controller which is the main component of the modular feature The sensor controller sends a five byte data packet to the main hub over the bus Within these five bytes there are two bits that contain both the serial number of the sensor 15 bits and the alarm bit MSB of higher order byte Because of this the functionality of the alarm system 1s entirely dependent on the sensor controller working correctly as well as the I C bus The alarm was designed initially as a standalone system with a monotonic square wave audio pattern that was merely triggered and not based on hard coded numbers A function was then developed based on testing discussed above to create a more appropriate sound and this function was inserted into the code for the main hub
