New Delhi, June 3 (UNI) Infosys Technologies today said it has received two patents by the United States Patent and Trademark Office (USPTO) in the area of holography and mobile communications.
''The patent titled 'displaying holographic three dimensional (3D) images' describes the realisation of actual 3D communication using computer-generated holography to send/receive information and the associated optical elements required to make a lightweight handset,'' said Software Engineering and Technology Labs (SETLabs) Head Subu Goparaju in a statement.
SETLabs is the research arm of Infosys.
Existing technologies use high resolution LCD to give the illusion of 3D, while actually displaying a 2D image.
Actual 3D dimensional imaging, which includes a representation of depth information along with amplitude of information is not being used in these cases. This patent addresses the issue of 3D in mobile communication.
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 hosts can roam over heterogeneous networks and also supports a layer 3 handoff.
