June 2021:
Snore sound based Sleep Apnea diagnostics intellectual property developed by Dr. Udantha Abeyratne and his team are available for commercialisation. The technology is the culmination of 20 years of ground breaking work leading to four patent applications including two granted ones in the USA (the rest are under examination at various stages) and a large portfolio of peer reviewed publications in international scholarly journals. A Matlab implementation of re-trainable technology and performance comparions against American Academy of Sleep Medicine scoring critera of 2007 (AASM 2007) are available. Prior comparisons on Chicago Criteria ("AASM 1999") are also available via peer-reviewed literature. Our software models indicate that the technology can diagnose sleep apnea at a sensitivity and specificity approching that of a standard facility-based polysomnography (sensitivity, specificity around 90%, 90%-- cross validation studies). Note that the model development data sets available to us (n=100 approx) had been scored per AASM 2007 clinical criteria. Thus, the resulting models require a straight-forward re-training (re-calibration) process on AASM 2012 data before they can be used on subjects diagnosed under AASM 2012 criteria (which is the clinical scoring standard in effect since 2012).

Assoc./Prof. Udantha Abeyratne is the inventor of the cough-sound based respiratory diagnosis technology (ResApp Health Ltd. (ASX: RAP)) and snore sound based sleep apnea diagnosis technology SnoreSounds.
He earned a PhD (Biomedical Engineering) from Drexel University, USA, and MEng and BScEE degrees in Electrical & Electronic Engineering from Tokushima U, Japan and U Peradeniya, (video here) Sri Lanka respectively. He also received formal post-graduate training in Higher Education (Grad Cert , U of Queensland, Australia) and Paediatric Sleep Science (Grad Cert., U of Western Australia, Australia). He is a Senior Member of the Institute of Electrical & Electronic Engineers (IEEE, USA), and a full Member of the American Academy of Sleep Medicine (AASM).
Dr. Abeyratne started his research career with a paper on coding techniques for low-bandwidth communication channels. His master's thesis was on a machine learning approach to the human brain activity analysis using electroencephalography (EEG, Brain Waves) and evoked potentials. This approach won the best paper award in ISBET Brain Topography Conference (Osaka, Japan, 1990) and also placed Dr. Abeyratne as a finalist at the Young Investigators' Competition in IFMBE World Congress on Medical Physics and Biomedical Engineering, 1991 (Kyoto, Japan). He completed his PhD (1996) with Prof. Athina Petropulu as the advisor, working on Higher-Order-Spectra and medical ultrasound imaging. The thesis developed slice-based low-complexity algorithms for blind signal identification, tumor detection in ultarsound images, and image deconvolution.

Cough Counting: Respiratory Diagnostics for the Developing and Developed Worlds
Cough is a common and one of the earliest symptoms in a range of respiratory diseases such as bronchitis, Congestive Heart Disease, pneumonia, asthma and pertussis. Cough frequency and coughing patterns can be useful in the differential diagnosis of diseases and in assessing the treatment outcomes. The nature of nocturnal cough patterns can also be highly useful in managing respiratory diseases. The manual counting of coughs in overnight (or long term) recordings is a tedious process. We are developing cough identification technology targeting ubiquitous consumer devices such as iPads/smart phones. Our methods will be available for both adults and children, including subjects with respiratory diseases. These methods need further development, validation and implementation on smart phones. Students with a background on Digital Signal Processing/Machine Learning/Pattern Recognition/iOS-Android programming and a keen interest in biomedical signal processing will be suitable for this project.

Differential Diagnosis of Pneumonia: Respiratory Diagnostics for the Developing and Developed Worlds
Pneumonia annually kills about a million children throughout the world. The vast majority of these deaths occur in resource poor regions such as the sub-Saharan Africa and remote Asia. Throughout the world pneumonia can be a serious problem in the aftermath of natural disasters and among the elderly. The management of pneumonia is difficult due to field-ready diagnostic facilities as well as the scarcity of trained healthcare workers. The World Health Organization (WHO) has developed a simple clinical algorithm to classify pneumonia. It has a reasonably high sensitivity but a poor specificity leading to over-prescription of antibiotics and the wastage of drug stocks. It has also met with operational challenges in remote communities. We are developing automated pneumonia diagnostic decision technology targeting ubiquitous consumer devices such as iPads/smart phones. Our mathematical algorithms will be available on self-contained smart phones. The phone will be used as the data acquisition, analysis and decision display unit. Our pilot studies indicate that it is indeed possible to diagnose pneumonia using cough sound analysis alone at high performance (sensitivity >90%, specificity>80%). We have also demonstrated that other clinical observations can be used alone, or, together with cough. Recent results we obtained suggest that other measurements alone (e.g. existence of runny nose, #days with runny nose, breathing rate and temperature) can achieve a sensitivity of 91% at the specificity around 72%. Specificity of our method is substantially higher than that, i.e., 38%, of the WHO algorithm while the sensitivities are similar. These methods need further development, validation and implementation on smart phones. Students with a background on Digital Signal Processing/Machine Learning/Pattern Recognition/iOS-Android programming and a keen interest in biomedical signal processing will be suitable for this project.
