Ilan Sadeh
Ilan Sadeh (born June 1, 1953) is an Israeli IT theoretician, entrepreneur, and human rights activist. He holds the position of Associate Professor of Computer Sciences and Mathematics at the University for Information Science and Technology "St. Paul The Apostole" in Ohrid, North Macedonia. Biography. Background and activities. Sadeh was the first to claim publicly in the Israeli media that Israel has no right to be called the "heir" to Holocaust victims and no right to represent Holocaust survivors. According to him, Zionist leaders have little cause for pride in their actions during the Second World War – Zionist  financiers withheld funds, while the JDC refused to help save Europe's Jewry, instead prioritizing the needs of the Yishuv in Palestine. The situation in Israel brought Sadeh to the conclusion that the political system must be replaced. He entered politics and led a movement in behalf of Holocaust survivors. He published a few articles in Israeli newspapers and had a public impact. Sadeh was elected a representative of that community and ran in the preliminary election of the Labour Party for the Knesset, or Israeli Parliament (1996), but was not elected. Following his activities, Sadeh was recently threatened and  accused of being a traitor. Sadeh has taken libel action over the charges in Israeli Court (2011). Research and development activities. Ilan Sadeh has had pioneering results in a few research and developments fields: "Smart camera," a long time before September 11 events, and "Homeland Security" projects, New Video compression, military applications for surveillance, seismic data processing and others. Sadeh has established three start up companies: Meitav, Israel (1982), Visnet (1996) and Vipeg (2000). He has been intensively involved in establishing and R&D of new start-up companies, establishing the infrastructure, dealing with intellectual property issues, managing all activities, raising  funding, coordinating consortium in EU FP5 FP6 programs. However, being unable to compete with the "Fat Cat" companies, bureaucracy, civil industry and the military establishment in Israel, as well as with the European Companies that were promoting only MPEG4, Sadeh could not raise government support nor get the support of the Israeli Army, temporarily left Israel in 2006 and moved to North Macedonia in 2011.

Video and Voice coding algorithms. A method and means for Tank Navigation. The method is operational even in severe electromagnetic environments, based on Sadeh's experience as Armored Forces Officer in Israel Army.
