Infosys awarded two patents by the United States Patent and Trademark Office news
03 June 2008

Mumbai: Infosys Technologies Limited today has been granted two patents by the U S Patent and Trademark Office. These patents are in the areas of holography and mobile communications.

''We are fostering a culture of innovation and investing in research through SETLabs - Infosys' Research Group, " said Subu Goparaju, head, SETLabs. "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 for holography, titled ''Displaying holographic three dimensional (3-D) images'' describes the realisation of actual 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. Actual 3 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 second patent, for mobile communications, 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.

There are a number of problems to 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 and a mobile host, where mobile host(s) can roam over heterogeneous networks and also supports a layer 3 handoff.
