Qualcomm, leading developer and innovator of the mobile devices and chips, has approached the Controller General of Patents, Designs and Trade Marks by filing patent application.

Admitting the application, the authorities have published the claims made by the company in their latest patent journal (PJ) giving a public notice.

The company has already presence in India and its other technologies are being used by leading domestic CDMA players such as Anil Ambani group firm RCom, Tata Indicom and Shyam Telelinks.

In its patent application filed on June 30 this year, it has claimed that the present invention can trace the altitude of mobile phone in any environment by using information from dead reckoning sensors, such as accelerometers, gyroscopes and geomagnetic sensors.

“The method and apparatus herein consist of combining the pressure information with information from dead reckoning sensors, such as accelerometers, gyroscopes and geomagnetic sensors and information from temperature sensors to separate what constitutes a change in altitude from a change in environmental pressure or temperature,” the company claimed.

Geneva-based UN agency World Intellectual Property Organisation (WIPO) has already granted patent for this invention, which is developed by Thomas G Wolf of Qualcomm.
