EOG Based Pointing Device for PC

The objective of this project is to develop a device to replace the computer mouse functions, thus allowing the movement of cursor and various clicking actions to be activated by eye movement and blinking. This device will enable a disabled person who has lost control of his/her hands to operate a computer.

EOG (Electrooculography) is the measurement of the bio-potential of the retina. By placing surface electrodes on the left and right sides of the eyes, the bio-potential that is dependent on the direction of eye gaze can be measured. When the gaze is straight, the EOG output is zero. When the gaze is shifted to the left or right, the respective right electrode's potential becomes more positive than the left electrode and vice-versa. There is an almost linear relationship between the angle of gaze and the EOG output of up to about +/-30degrees.

Actimeter

The objective of this project is to develop the Actimeter that can be worn and enable the client to record his or her sleep/wake pattern. The parameters include body temperature, surrounding light ambience and arm movement of the patient. Recorded pattern is displayed on the computer and used for diagnosis and treatment by doctors.

Actimeter is a medical device used for measuring sleep quality in individuals suffering from sleep disorders, such as insomnia, Periodic Limbs Movement (PLMS) etc. The assumption is that when a person is not in deep sleep, there is significant body and limb movement. On the other hand, when one is in deep asleep, there should be minimum body movements. With the help of the Actimeter, doctors do not need to observe the patient’s entire sleep activity physically because the data, captured by the Actimeter, is later transferred to doctors’ computer system for diagnosis.

Mobile Display for Patient Monitor

The objective of this project is to develop an Electro-cardiograph (ECG) that is capable of recording 3-lead ECG signals and transmitting the signals over to a PDA device via Bluetooth interface. The user interface on the PDA allows the user to display either one of the 3 bipolar limb leads and automatically compute the pulse rate. In addition, it is capable of storing the data in a SD card which enables it to be used in ambulatory applications such as a Holter monitor.

Clinical Audiometer

The objective of this project is to design a 2-channel clinical audiometer to determine the hearing ability of each individual. The audiometer consists of speech, tone and talkback modules.

The speech module delivers a live speech through a microphone and / or a pre-recorded speech through external devices, such as MP3 and CD players. The tone module supplies inputs of pure tone, narrow-band noise and speech noise to the patient. The talkback module (that includes patient's response) enables the patient to communicate with the clinician in a two-room setup.

Electronically Controlled Infusion Pump

The objective of this project is to develop an electronically controlled infusion pump that can deliver the right dosage of biologically compatible fluid or electrolyte into the bloodstream of a patient for life saving or therapeutic purposes.

The infusion pump has a thermo-preconditioning unit, incorporating a precision temperature sensor that allows preheating of fluids before infusion.

Similarity Search System for Chemical Databases

The objective of this project is to design a search system to search for molecules – whose structures or sub-structures are similar to a given query molecule – from a database of chemical molecules.

The search system brings the efficiency of drug discovery to a higher level.

Protein Feature Extraction & Structure Prediction

The objectives of this project are to implement algorithms for extracting protein features from sequence and for prediction of protein structures and folding.

In this project, Machine learning algorithm, Probabilistic method, Secondary structure propensities calculation and Transmembrane Helix prediction were developed. A database  was also created for housing secondary structures information.
