The Lab, set up in 2000 with the aim of bolstering research practices, has filed over 100 patent applications in the last 18 months. The two patents have come at a time when the company is looking at non-linear growth model, breaking the link between revenue and employee growth.
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.
Across Indian IT services companies, the $5.7-billion TCS has filed over 200 patent applications in the last five years. Says Avinash Vashishta, CEO, Tholons (an advisory firm), "India IT majors have been running a software factory and R&D is one area where they have to do a lot. The focus being services, barring a few small exceptions they have not been able to create a business around R&D — that is, develop IP products and market them." Now, to get to the higher billing tasks and delink revenue growth from manpower growth, a focus on R&D is a must. The top IT majors could show the way.
