Exactly spot on Charles.
I personaly remember someone I dont like very much in the steadicam forum warning me not to use a spiral cable in a possible sled productiopn design because its patended from Garrett.
i remember spiral cables for my guitar from the age of 7.
Also the adjustment of the angle of the spring like early sks and provid, and Iam talkig about the adjusting mechanism was in use for other machines, but it was patended for steadicam arn.
Also the roll cages for remote heads are in use for at least 10 years but for steadicam they are patended to be used on a sled----allien...
So its just other ideas that give you an idea and you make something new and then you patend it like its something from space.
I have personaly placed a roll axis on my sk2 sled 8-9 years ago and made a music video.
At the time I knew nothing about the allien but I HAD OPERATED remote heads with roll so I said why not.
It didnt balance nice because I didnt made it modular, and there was no gyro sensors.
The funny thing is that when I have mention it to another operator at the time he said noooo dont mess up with remotes and stuff, steadicam is made to be mechanical and simple in stabilizing, and this guy who apparently is in my oppinnion one of the greatest ops I have ever seen, 8 years after he bought the allien revolution---I dont quite know if i CONCIDER THIS AS TO BE A LUCKY BUY....
So patents are not always something that hasnt done before ever, but something that by changing it and placing iot to something different is a new concept.
And my last question is....why glidecam didnt use this design from the very start and choose to go with the 3a style arm which it was an expired patent?
Why now and why risk being accused of copying with the 3a style if they were positive that this is working as well and its also free?
Its all money layers and profits .
For me its all the same story coming in circles.
So now Charles that you are going to be a millionere what present are you gonna buy me? he he he he

Just in case you think wrong I have also got the idea of this design from the pro geometry only I had some more mecanisms for feature adjustments apart of extension springs..
