Doctoral researcher Yuvraj Agarwal, a NRI, of the University of California San Diego (UCSD) in collaboration with computer scientists has created a plug-and-play hardware prototype for personal computers (PCs) that induces a new energy saving state known as “sleep talking”.
Normally PCs are in awake mode, where they consume power even if they are not being used, or in a low power sleep mode, where they save substantial power but are essentially inactive and unresponsive to network traffic.
Most of the tasks that people keep their computers on in the awake mode are to ensure remote access and availability for virus scans and backup, maintaining presence on instant messaging (IM) networks, being available for incoming voice-over-IP (VoIP) calls, and file sharing and downloading.
Following this realisation, the team built a small hardware and software plug-in system that allows a PC to remain in sleep mode while continuing to maintain network presence and run well-defined application functions.
The scientists named their system “Somniloquy”, which means the act or habit of talking in one’s sleep.
Agarwal completed his engineering degree from Pune University in June 2001.
