Project Experience:
Power Distribution System Role:
The DC Power Center serves as the central entry and distribution point for the aircraft primary DC
electrical power distribution system. The DCPC includes secondary power switching elements for control
and protection of the secondary power distribution assembly, cabin feeders,and control and protection for
the power output to the electrical management system control and display units.
Responsibilities:
 Module requirement document in DOORS
 Module implementation document
 Worst case Functional and Stress Analysis.
 Simulation using Cadence.
 Co-ordinate with FPGA team to prepare Board MRD and updated the requirements based on their
MRD.
Dental Curing System:
The LED curing light system is a device used for the polymerization of light sensitive dental
materials on the 450-470nm range. The LED Curing Light System consists of a Charging Dock and a
detachable Hand piece. The Charging Dock is used to hold the Hand piece unit while charging and the
Hand piece is used for curing purpose. The Hand piece shall contain an LED light engine, rechargeable
battery and PCB’s. A microcontroller will be used to control three modes: (with 5, 10 & 20 seconds) each
mode specifies LEDcuring output and audible beeptiming indication. The device will have two push button
switches for mode and trigger selection. Mode switch is used to select the curing mode and a trigger switch
