Most bits are constant, but it is a function of the component matching capability of the manufacturing process. The better the matching, the better the process. This is especially true when the process is used for analog circuits, where matching is an important feature/assumption. Fortunately, the better the matching, the more bits that will be random.

This is a bit of old news. I have already authored and been granted several patents in this area.
6,906,962 Method for defining the initial state of static random access memory
6,828,561 Apparatus and method for detecting alpha particles
6,738,294 Electronic fingerprinting of semiconductor integrated circuits
I have several other ideas for application of this technology and would be happy to discuss
if someone is interested.

I have read the patent. It is clearly in conflict with claim 1.
I have already been in contact with the EFF. I became aware of EZTracker several years ago. I think it was before 9/26/01. I am currently investigating and trying to contact the authors.
Obviously nobody at Clear Channel is awake at Church. There aren't too many large Churches around where you can't get a copy (tape, CD, video) of the service just a minute or two after the service ends.
Church technicians have been cobbling together systems to record and reproduce live events for several decades. Systems that record digitally and have at least a some editing functionality have been around for at least 5 or more.
The main difference between the commercial systems they describe and the Church systems are that they are trying to make money. Until the advent of cheap digital recorders and mp3's they had the market cornered. Now they need to find some way to commercialize what we used to call bootlegging. Unfortunately, a non-commercial entity has been bootlegging for a long time.
After a looking googling:
"The Disney system was described in: Proceeding of the Second
International Symposium on Fireworks. 1994
4", 6", and 8" shells are lifted altitude ranging from 100 feet to 2000.
Using air pressure ranging from 20 psi to 120 psi. Their system
"Uses an electronic ignitor assembly controlled by remote located
computer to detonate the shell in the sky." No further description is
provided, other then the statement; "The electronic ignitor need not be
inserted in the shell until the actual use." The system is patented,
perhaps the patent provides more information.
Actually -- On further research. The ignition system is describe in detail
in vol. 2! "This electronic ignitor uses an electrolytic capacitor for
energy storage, a custom integrated circuit for programming logic
and timing, and a conventional pyrotechnic squib for the ignition source."
The timing resolution is reported to be; plus/minus 0.015 seconds!
They system that releases the compressed air also send a launch
sequence to the igniter."
Disney World has been using this technology for
a long a time. At least 10 years. Disney Land has just finally caught up. Every piece that is lauched contains a small electronic timer that ensures that displays are perfectly timed and synchronized.
The discovery channel (I think) ran a show on this many years ago.
You've got this right. I have a multi-function printer that installs a pile of crap every time
the systems boots. I wouldn't mind so much if the thing worked real well, but it doesn't. I will never buy anything from HP again.
I read "regular digital projector" as "regular Sony digital projector," as in regular video tape versus BetaMax video tape. I would feel better if they had stated "any digital projector."
I've RTFA several times. Don't see the information you suggest is there. Many others seem to have missed it as well. They do mention the issue of whether they will license to others.
Maybe my original posting wasn't clear. The real beauty of the system I was trying to describe is the low cost and intensity of the projector. It is a single frequency infrared laser with some
simple optics to raster scan it much like the electron gun in your CRT. Big differnce is that no vacuum is required. Dots are painted on the screen/wall is a raster pattern and the laser is
alligned to this pattern. Works just like a CRT only *much* bigger.
Not the same technology. By doping the crystals
one way, they are tuned so that the energy the absorb from the infrared (invisible) spectrum is re-emittted at another specific frequency (red, green or blue) in the visible spectrum. They create three types of differently doped crystals. One for each color. The crystals are ground up separately and mixed with an opaque binder/adhesive. Then a dots are painted on a screen or wall in an R-G-B pattern like you TV or monitor. A single infrared Laser (invisible) shines on the dots like the electron gun in you monitor. Fortunately, no vacuum is required for the laser beam.
The patent "principle of improvement" is in play here. I think it would allow you to patent a preferred embodiment of a projector with 3 very specific frequencies subject to any previous patents with less specific frequencies.
This is kind of like someone patenting a table with 4 legs. Then you patent a table with 4 legs made from maple. You still need access to the first patent, but you can prevent anyone else from making one from maple.
This reminds me of a technology
I read about a while ago.
You can dope crystals with rare earth elements in such a way that when they are illuminated with infrared light, they up-convert (heterodyne) it to some part of the visible spectrum. The doping of the crystals can be controlled to produce red, green or blue light.
These crystals can be ground up and painted onto a screen or even the side of a building. Then all you need is an infrared laser to scan the the sreen and you have an extremely bright and cheap full color display.
I haven't heard much lately about their progress so I assume they are having some technical or financial delays.
This appears to be a very cool technology. I have wanted to put a front projection system into my home, but have no way to control ambient light during the day. When this screen becomes available, it will probably push me over the edge.
I assume the three frequencies that are reflected are fairly well tuned. I wonder if this means I will be stuck purchasing a Sony projector to match these? I also wonder if Sony may be able to stop others from making matching projectors since they probably own some Patents around this technology?
They say the single most important person for an employees happiness is their boss.
I think one of the most important properties of a boss is Trust. Trust is at least two dimensional. To trust a boss they must be competent in their roll and they must have your best interests in mind. I think any questions about their experince and skills for the tasks they must perform are important. Secondly, you have to figure out if they care about you and your success.
I would suggest the book Topgrading by Bradford Smart as a good reference for asking the right questions and asking them in several ways to correlate results. Interviewing should be a lot like taking a survey. Best to ask the same thing several times for verification.
Patent 5,625,670 has 276 claims! Most have 30 or less. My summary of claim 1 would be "any computer system with Email that transmits Email to another computer system using RF." Unfortunately whoever wrote this patent made all the other claims dependent on claim 1. Thus, if claim 1 is poorly written, it can blow the whole patent. As far as I can tell claim 1 was botched.
If I was RIM, I would argue the that claim 1 only says RF (Radio Frequency). It does not say "wireless" RF. Clearly RF on wires sending Email was existing prior art long before the application.

Not joking as related to using random data from a SRAM. Please read the last patent

Eventually the integrated systems will be much more than adequate for 99.99% of the population.
Assimilation is inevitable. Resistance is futile.
I exchanged Email with the author of EXTracker. Looks like Mode 2 was established back in 98 or 99. I have put him in touch with the EFF.

This program does the same thing and has been around for a number of years: EZTracker.

Someone mod this guys comment up!
Go out and get the book Rich Dad, Poor Dad. I know it's a stupid little paper back. However, if you take it seriously, it can change your life.
The other thing you might want to do is network by joining Toastmasters. Both of my sons (18 & 19) go and they think it is great.
The only thing better would be the Infrared Laser scheme that I mentioned in another thread in this article.

What someone needs to do is set up a site where people can help fight this crap by supplying references to prior art for bogus patents.

This is not Sony's history. I do remember them trying to protect Beta format tapes until they died, even though they were technically superior.
