Infosys Awarded Two Patents by the United States Patent and Trademark Office
Patents Granted in Holography and Mobile Communications
Bangalore, India - June 3, 2008: Infosys Technologies Limited (NASDAQ:INFY) today announced that it has been granted two patents by the U. S. Patent and Trademark Office. These patents are in the areas of holography and mobile communications.
Commenting on the occasion, Subu Goparaju, Head - SETLabs said, “Innovation is imperative for growth. We are fostering a culture of innovation and investing in research through SETLabs – Infosys’ Research Group. We set up an Intellectual Property (IP) cell in 2004 to leverage the power of IP for our growth and we are pleased to see results.”
The patent titled ’Displaying holographic three dimensional (3-D) images’ describes the realization of 3-D communication using computer-generated holography to send/receive information and the associated optical elements required to make a lightweight handset.
Existing technologies use high-resolution LCD to give the illusion of 3-D while actually displaying a 2-D image. Three-dimensional imaging, which includes a representation of depth information along with amplitude information, is not being used in these cases. This patent addresses the issue of 3-D in mobile communication.
The patent titled ‘Method and system for providing reliable and fast communications with mobile entities’ proposes a mobile Internet Protocol-based solution to support generic mobility over heterogeneous networks.
A number of problems must be overcome to support generic mobility over heterogeneous networks today; this solution leverages a split-TCP type approach, where the TCP connection between the communication entities is split at a suitable gateway.
The solution does not require any extension at the mobile host and provides improved performance even for mobility across heterogeneous networks due to an inherent ability to adapt to changing network characteristics. It supports communication between two mobile hosts or between a fixed host and a mobile host, where the mobile host(s) can roam over heterogeneous networks. The solution also supports a Layer 3 handoff.
