Projects

Project: Zero Energy Smart Building

Sponsor: Robert Bosch Center for Cyber Physical Systems

The main motivation of this project proposal is to reduce dependence on the power grid. The objective is to utilize as much energy as possible from various renewable sources, including solar and wind. This will help in reducing carbon emission, thereby contributing to ongoing efforts to limit the accumulation of greenhouse gases. The long-term goal is to achieve a “zero energy from the grid” mode of operation, if possible. Initially, our focus is on a single building.  Project involves monitoring of the loads, and depending on the supply demand side load management is implemented.

Project: ASIC components for interfacing to various sensors in the next generation LCA

Sposor: DeitY, Ministry of Communications and IT

Objective is to develop a prototype ASIC with a functionality of interfacing to one or more sensors in the next generation LCA aircraft.The current generation LCA aircraft’s electronics sub-systems for flight control are made out of imported Integrated Circuits. For example, the Air Data Computer is the one of the key electronics subsystems in the light combat aircraft and interfaces to a number of sensors within the aircraft and digitizes and processes the signals from them and communicates with other air data computers in the aircraft. It is currently implemented using many discrete components on a printed circuit board (PCB). In this project we would like to take the first steps towards this aim by identifying key components from the sub-system, and design a custom chip to incorporate their functionality and show a proof of concept sub-system.
