Abstract: Recently, optically reconfigurable gate arrays (ORGAs) have been under development to produce radiation-hardened field programmable gate arrays (FPGAs). An ORGA consists of a laser array, a holographic memory, and a programmable gate array VLSI. Since holographic memories are very robust against radiation compared with semiconductor devices, the ORGA exploits the radiation tolerance of holographic memories to increase the radiation tolerance of the entire ORGA device. This paper presents experimentally obtained results of a part of an ORGA device. We have conducted an experiment using a cobalt 60 gamma radiation source to confirm the total ionizing dose (TID) tolerance of an ORGA. Results show that a laser used in the ORGA can function correctly even after receiving a 300 Mrad TID.

Abstract: It has been noted that water crisis are reaching at alarming proportion in Pakistan, due to miss management and low literacy rate. Most of households use water pump to get fresh ground water and fill there overhead tanks, but due to less technical involvement enormous amount of the water is wasted. Automatic water control system provides significant solution to this issue. Methodology of this system is all depend on the electric conductivity of water and logical signals given to different logic gates. This system terminates the water pump from over flow and also shows indication at different levels of water in overhead tank.
