In this section our Latest News and the most interesting Activities-Events are presented.

2008

Since Tuesday 25th March 2008 information about a respectable scientist that has played a very critical role in the History of Tsiriggakis' Gearless Differential is revealed. Learn about Mr. GKIOKAS E. Thomas.

2007

Since 1983 we conduct research, the result of which is the construction of a mechanism. This mechnanism is equiped with appropriate sensors and brings us very close to the study of gravity. When this mechanism operates at its capacity, then it looses weight. Therefore we have the principle of Counter-Gravitational Experimental Mechanism (CGXM). (click here to learn more...)

 

A team consisting of Mavrianou Lila, Vlastou-Katsouli Ioanna, Kapenis Paris, Tsiriggakis Vasileios, Vogiatzis Petros, students of ALBA university aims to create a company managing inventions. The initial portfolio of the company contains all of the mechanisms that are presented in this site. (click here to learn more...)

 
On Saturday 6th January 2007 the scientific magazine "Popular Science" published an article dedicated to Tsiriggakis technology. We want to kindly thank Mr. Tsimitakis Matthew for writing a precise article. The article is written in the Hellenic language and is available for downloading!

2006

Since Monday 25th December 2006 the most critical information concerning the Tsiriggakis Research is published. The "Antikythera Mechanism" is related with Tsiriggakis kinematical Theory. (click here to learn more...)

2004 - 2005

On 13th of September 2005 the inventors: Mr. Tsiriggakis Theodoros, Professor Dr. Spentzas Konstantinos and Mr. Tsiriggakis Vasileios have applied for an international patent concerning A Controllable Differentiation Differential Mechanism, with Undulated Planet - Gears. (click here to learn more...)

As far as the Controllable Differentiation Differential Mechanism, with Undulated Planet - Gears is concerned, more information such as the filed material, three clips and more photographs are availlable for downloading (click here to learn more...).

In April 2005 the first article that briefly presents the Controllable Differentiation Differential Mechanism, with Undulated Planet - Gears has been published. The Controllable Differentiation Differential Mechanism, with Undulated Planet - Gears is a mechanism which is already known by the NTUA since December 1987. It has been applied for a patent on Friday 17th September 2004 and the first article about it has been published in April 2005. The article is availlable for downloading from our web page in pdf format (5,874MB). (click here to learn more ...)

On Friday September 17 2004, Mr. Theodore Tsiriggakis and Mr. Vasilis Tsiriggakis have come up with a new patent application concerning a completely new Differential Mechanism. Professor Dr. Spentzas Konstantinos, Director of Vehicles Laboratory of NTUA's Mechanical Engineers Department, has played a decisive role for the research to be conducted. This patent application is a result of more than a decade of research on innovative ways of transmitting motion. (click here to learn more...)

In March 2004 we published a critical presentation of Tsiriggakis' gearless differential in the International Journal of Mobility and Vehicles Mechanics (Volume 29, No.4, 2004, pages 25-46). The presentation is availlable for downloading from our web page in pdf format (7,959MB).
