Client: NMS Communications, UK.
Project 1: T1E1 Telecom Test Tool
Position: Software Engineer
Description: The TIE1 Telecom Test application was designed and developed to automate the telecom testing needed for international industrial compliance. The TIE1 Telecom Test application would allow user to place a call to the T1 Trunk line from a host PC via the TIE1 Media Gateway UUT. Once in a connected call, the user will be able to: (1) Play DTMF tones (2) Play a .VOX file (3) Record a .VOX file (4) Hang up the call

Project: Health Monitoring System
Client: National Institute of Mental Health and Neuro Sciences, India
Description: The automated hospital system was designed to keep track of the health of patients in the hospital. This would be accomplished by monitoring different vital parameters. The system would have to be designed to monitor all the patients simultaneously. For efficient monitoring of each patient in the hospital, the database must, at any given instant, have the latest value of each parameter for each patient. If the value of any parameter for a patient exceeds the normal permissible value, a doctor has to be alerted so that he could attend to the patient at the right time.
Responsibilities
? Analyse the automated system and design the modules accordingly.
? Designing of the data input system.
? Interfacing the sensors with PIC module using RS232 protocol.
? Programming the inbuilt ADC in PIC16f873.
? Interfacing the PIC with GSM module using AT commands.
? Designing of an emergency alert system.
? Testing the interaction of the GSM module with the centralised database system.
? Evaluated and ran test cases on a beta version of a suite of data from sensors.
Environment:
Software: C, Assembly Programming (MP-ASM), Salvo.
