This paper explores the software and hardware developed for real time process and analysis from an Electrocardiogram ECG. The portable ECG device is used to capture data from the heart and lungs which is automatically converted from analogue to digital signal for further analysis. Via the use of an ECG device, data is collected at two different speeds i.e. walking and running respectively. The collected...
This paper discusses the design of an electronic stethoscope which is used to listen to the heart and lung sounds. The sounds are captured from the surface of the skin, after which they are filtered and amplified to enable the signal level to exceed the audible threshold. A loudspeaker is used to clearly listen to the processed signals. The signals are sampled, digitised and then analysed using the...
Due to the nature of multicast communication, security is an important challenge that needs to be addressed. It is of paramount importance that the confidentiality and authentication of messages transmitted between participating mobile nodes be maintained due to the sensitivity of the messages. This paper presents a high-level dual authentication scheme that would effectively prevent unauthorised...
