Mr. Ohlig: I am not referring exactly to a physical film as technology has been made public regarding liquid crystalline light valves (thermally written) and liquid crystalline drawing devices that "act" as reuseable films. Perhaps I was not clear. Two companies, which I do not have any ties to, have US patents: Asahi Kogaku Kogyo Kabushki Kaisha, Tokyo, Japan patents 5,026,145; 5,062,692; and 5,078,474 (1988-1990) Omnichrome, CA patent 5,556,884 (1995) The abstracts are available at http://patents.uspto.gov/index.html I have no additional information but am interested in anyone who has purchased devices or licensed similar technology. I hope this is of use. Sincerely, Dieter Herr Dieter Miese 3620 Kaff die Miesen Auf den Bergen *************************************************************************** * TechNet mail list is provided as a service by IPC using SmartList v3.05 * *************************************************************************** * To subscribe/unsubscribe send a message <to: [log in to unmask]> * * with <subject: subscribe/unsubscribe> and no text in the body. * *************************************************************************** * If you are having a problem with the IPC TechNet forum please contact * * Dmitriy Sklyar at 847-509-9700 ext. 311 or email at [log in to unmask] * ***************************************************************************
