Infosys Technologies has been granted two patents in the areas of holography and mobile communications by the US Patent and Trademark Office. A source said that 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.

Meanwhile, 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 company said.

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.

The infotech behemoth, which defines, designs and delivers IT-enabled business solutions, has been focusing on providing strategic differentiation and operational superiority to clients. The new patents are expected to boost the activities much more.
