Infosys awarded 2 patents by USPTO

Subu Goparaju, head of Software Engineering & Technology Labs (SETLabs), the research arm of Infosys said, "the patent titled 'displaying holographic three dimensional (3-D) images' describes the realization 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 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.

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.
