I also recall that they were a bit** to align.  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-04-2003 03:43 PM                     The honeycomb was used for 900w or smaller lamps The two piece optical system was actually very sim[,e to align also that US patent number 037A.0001.P1 comes back invalid  |  IP: Logged Mark A.

But I've seen the papers from Washington DC so.......  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-04-2003 09:34 PM                     I see kodak has another patent aplication for a method of preventing buckling of film application # 20020071099 The Zeiss Ikon device that was placed between the lamphouse and directly behind the apperture was called the "Bidfensterlinse" and produced considerable increase in light according to Richard Mitchell  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-04-2003 10:12 PM                        quote: I see kodak has another patent aplication for a method of preventing buckling of film application # 20020071099 Yes. The Kodak Enhanced Theatrical Experience (ETE) program explored many areas that could improve presentation quality.  |  IP: Logged Michael Schaffer "Where is the Boardwalk Hotel?"

But it has been a while since I worked with one, so I am not 100% sure.  |  IP: Logged Steve Guttag We forgot the crackers Gromit!!! Posts: 12814 From: Annapolis, MD Registered: Dec 1999 posted 08-05-2003 07:42 AM                     Here, on my 2000th post... The problem people are having with "claims" is the complete lack of documentation. Its all very hush-hush but "trust us it works." Technical claims that have not been subject to peer-review are just that, claims and should not be taken as facts. Using the big chains as a claim of quality is a joke...they are rarely about quality they tend to push the industry in the opposite direction and instead, compete for bankruptcy. If the patents are indeed applied for, then they are protected. As such, the developers should be writing papers for such organizations like the SMPTE and BKSTS. Then demonstrate their invention to the societies. That is how engineering accomplishments are presented, not "pssst, we got this great new product is will make a sun out of a flashlight, tell everyone but don't dare be specific." Now if they don't have a patent or a patent pending then there would be liability around discussing it though if they are documenting their designs those documents can be used to help show when the work was being done. I can neither dispute nor support the claims but mere words of the greatness is also unsupportable. Steve  |  IP: Logged Ken Layton Phenomenal Film Handler Posts: 1452 From: Olympia, Wash. USA Registered: Sep 1999 posted 08-05-2003 10:03 AM                     Boy, I couldn't agree more more with you Steve on this one.  |  IP: Logged Mark A. MacLellan Film Handler Posts: 23 From: Montreal, Quebec Registered: Jul 2003 posted 08-05-2003 01:14 PM                    I made the decision to post some information in this forum not because I wanted to promote the product or gloat about it. Rather, I have been reading some of the "buzzing" about Technalight and some of the speculation was incorrect so I wanted to set the record straight. Some of you describe my information as unsubstantiated claims. That's fine. We have nothing to prove to anyone here; believe it or don't believe it. As someone who works in the biz and loves film, I'd be excited if someone told me about something that could enhance the projected image very dramatically. And there is no element of "trust us, it works" with this product. Each and every client who has purchased the system since it's inception has taken a "trial period" to evaluate the results. As Greg Pauley said, he monitored his readings on conversion #1 for almost a year before buying two more conversion kits. Many others have done the same kind of thing. I guess there's not much else to say other than I have never seen a better motion picture presentation than that of Technalight and nobody will ever convince me different. We have just hit the crest of the R&D wave after 5 years of development and refinements and experimentation. I make no apologies if some people feel that we have not followed the proper protocol to present this "engineering accomplishment". But quite frankly, some of you will always pick this apart no matter what because everybody is entitled to their own opinion. The most important thing is this: Are those purchasing the systems satisfied with the results? Yes. Are their cleints, Joe & Cindy patron, seeing a much brighter image, with better definition and more vibrant colors then before the Technalight installation? Yes. 'Nuff said.  |  IP: Logged John Pytlak Film God Posts: 9987 From: Rochester, NY 14650-1922 Registered: Jan 2000 posted 08-05-2003 02:13 PM                        Once you have your patent protection in hand, writing an SMPTE paper should be fairly straight-forward. In addition to discussing the basics of the technology, actual data showing the improvement over other designs could be presented, perhaps comparing the performance of various alternative designs that were considered. Here is a link to the Society of Motion Picture and Television Engineers (SMPTE) website, with instructions on how to submit a paper to the Board of Editors for publication in the SMPTE Motion Imaging Journal: http://www.smpte.org/smpte_store/journals/ It's probably too late to prepare a paper for presentation at the SMPTE Technical Conference in NYC this November 12-15, but here is a link: http://www.smpte.org/conferences/145tech.cfm If you are an SMPTE member with an on-line password, here are some examples of technical presentations from past conferences: http://www.smpte.org/members_only/library/download.cfm?file=pytlak.pdf http://www.smpte.org/members_only/library/download.cfm?file=morton.pdf And here is the on-line SMPTE Motion Imaging Journal: http://www.electronicipc.com/JournalEZ/mo/toc.cfm?code=4539001  |  IP: Logged Mark A.

I will save all of that info so I have it close at hand. This is something that we have certainly discussed on occasion and something I'd like to see happen in the near future but with all of us being on the road selling & installing...well, time has been a challenge. Thanks again!  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-07-2003 11:14 PM                     Well here is a 3K technoalite reflector installed Sorry for the poor quality of the shots  |  IP: Logged Mark Gulbrandsen Resident Trollmaster Posts: 16657 From: Music City Registered: Jun 99 posted 08-08-2003 12:41 PM                     Nothing about that stuff is special. Thats an Ernamann reflector and what appears to be a standard 3kw Christie xenon lamp. I guess thats why he is so secrative about the whole thing........there's nothing special at all in there.

MacLellan Film Handler Posts: 23 From: Montreal, Quebec Registered: Jul 2003 posted 08-08-2003 01:02 PM                    I hesitate to even respond to this but the ignorance astounds me. This is not an Ernemann reflector. It is not a Christie lamp. It is not even a 3K lamp, or even close to that. This is actually one of the earliest prototypes produced and looks nothing like the system on the market today. I recognize this installation...  |  IP: Logged Gordon McLeod Film God Posts: 9532 From: Toronto Ontario Canada Registered: Jun 99 posted 08-08-2003 08:46 PM                     It is a 3K lamp and was installed less than a year ago and you will note I haven't been critical of it but it is sure nothing new in technology of either installation or design  |  IP: Logged
