A Non-invasive Wireless Monitoring Device for Children and Infants in Pre-hospital and Acute Hospital Environments

Introduction

The information and links contained on this webpage form the results of a dissertation carried out by Phillip Winderbank-Scott under the supervision of Dr Payam Barnaghi and Professor Roma Maguire at the University of Surrey in 2016 as part of the Communications Networks and Software MSc. The purpose of this project was to produce a flexible and working prototype using off-the-shelf components that would wirelessly transmit data from sensors to an Android pad.

 

Symbolic Aggregate ApproXimation Raw Data

 

The raw data collected from experimentation on the settings to use for an implementation of SAX within this project can be found in the following document: SAX Experimentation

The sheets within this Excel document are labelled with the settings used for each variation of settings. All experiments were carried out with an 8 symbol alphabet.

The links below will take you to the correct sheets for each experiment:

10ms sample, 40 sample segment size, two point averaging

4ms sample, 120 sample segment size, three point averaging

4ms sample, 200 sample segment size, no averaging

4ms sample, 200 sample segment size, no averaging, peak limiting

4ms sample, 180 sample segment size, no averaging, peak limiting

 

As an example of the final dataset, the graph below shows the comparison of the normalised data collected and a five sample averaging of the SAX data.

 

Latency Data

 

The data collected to measure the transmission time for the Bluetooth Low Energy module used in the project is shown in: Latency Experimentation

There are two sets of data:

Sample time including transmission

Sample time excluding transmission
