-- CF adapter card (http://discussion.visorcentral.com/vcforum/showthread.php?threadid=7565)

Has anyone heard any new news on the CF adapter springboard?

Good news!

TTRMKR is developing a CF adapter that uses FAT file system & has applied for patent. He is thinking about developing a smart media card adapter, too. He doesn't have any time line on his site, though.

Patent? Gimme a break

You gotta be kidding - a patent for a Springboard to CF adapter? That's ridiculous! For memory cards all it takes is a PCMCIA to CF adapter with three white wires (modifications to the circuit board). The software to make the PalmOS use a CF card is the hard part, but I would think that since TRG has already done it in the TRG Pro, that would establish "prior art".

I wonder who I have to talk to to file opposition to a patent application?

NOT SO FAST!

Dave,

I didn't explain it enough, but what TTRMKR is trying to patent includes his software. Also it is not an adapter for PCMCIA card...it's for extra memory. I don't know if his system is identical to TRGPro's, but I doubt it. There's more than one way to skin a cat....

I don't think it's ridiculous to patent his idea. He deserves some credit. Also his intention is not making money. Rather, he is trying to protect interests of many Japanese Visor owners who provided him with capital to develop CF adapter Spring board(supporters of USMB-User-Made SpringBoard). It would be unfair for those people (and TTRMKR) if a big company just copies his product. FYI-I have no personal interest in his invention. I didn't send money

I agree with Taki.

(Hope this is not the start of another patent thread)

Bret, thanks for your support! I don't want to start the whole "patent" argument, either. I shouldn't have used the p-word. This would be my last post regarding this subject.

Toby, Now I'm not sure "patent" is the right word. It's called "jitsuyou sinan touroku"--if I translate literary, "utility new idea(my dictionary says 'utility model') registration"--I have to do some research on Japanese law to figure out exactly what it is, but it sounds more like cross between patent & copywright protection.

Taki: Yeah, it does sound like a cross, but it leans more towards what would be comparable to patent over here. Laws are just a bit different obviously. Here, patents are for new ideas or inventions, whereas copyright is more for literary works or recorded formats (books, movies, computer code, etc.).

Discussing how to improve on a patented idea is not a violation of law. In fact, you could even get a
patent on the improvement (which is public record among other things), but wouldn't be able to manufacture it until you reached an agreement with the orginal patent holder.

Of course, if your idea is a huge improvement, the usual
solution is to cross license your patents (if yours does infringe on his).

(On another note, you CAN patent software)

Correct me if I am wrong but from what I understand, the dragonball EZ CPU uses 24bits external address bus only capable of addressing 16MB of memory. Even CF on springboard wont change that fact. Maybe TTRMKR has also patent his way of multiplexing addresses to increase the the memory to > 16MB (hopefully).

James

You are correct about the 24 bit address bus. However it's not a problem for CF cards since they only have a 10 bit address bus. How do they get 64MB+ on a 10 bit bus? Well, there's actually a "multiplexer" inside the card that makes it look like an IDE disk drive. All data transfer into and out of the card actually happens through a single 16-bit register.

The good news is that makes the addressable size of a CF card virtually unlimited (many gigabytes). The bad news is that it makes the software interface a bit tricky. You can't address the card as linear memory so you have to cache in onboard RAM and patch a whole bunch of system calls to trick the memory manager into looking in the cache.

thank you for the info. I am interested in reading more about it. I appreciate if you could also give me some pointers/links on how the multiplexing and mapping works (software/hardware).

James

As far as the Japanese patent goes, I'm almost positive that it doesn't cover a similar product in the U.S., unless they've filed for a patent over here as well. I took a business class a couple of years ago and that is what we learned, unless they've changed things in the past couple of years, which I doubt (moving at the speed of government!!!)

The best way to get the technical details is to download the CF specification from the Compact Flash Association website. The spec is free, but you'll have to fill out a registration form to download it. The information it contains is highly technical and not that easy to digest, but it does cover everything including the electrical interface, software interface, metaformat, and ATA command set.
