Wihtes in their patent 6172504 claims that the flash phase cirquit solution is new, but if one looks close one could intrepet the cicuit as a
bar grap meter! Still the ladder is semi log rather then linear like a LM3914 unit, so i wonder whats so unique whit this patent?
Not to forget to mention flash ADC's then its just a matter of measuring, AC, DC, phase, current, its just another parameter!
Has any one looked into 5523690, 6005392 and 5148151 if they are similar to this patent?
What comes close to my mind is phase counting, could simply be implemented with a pll and a counter, btw that's i suppose every MCU based detektor actually does these days, so using phase traps in HW doesn't seam any new to me... OR?... coments on this patent subject invited.
Does any one know of a detector that uses phase counting in discrete HW (no MCU counting) and later displaying this like a number or bargraph when phases lock ocurr, angle counting, not a bargraph measuring plain DC.
Btw again, sometimes looking into many patents
it seams that a wast majority are recykled stuff
with somewhat little "holding" content and many
patents have quite limited strengt! Some barely hold!!
As Don the tijana Lancaster says, its a bit
of pain the whole patent issue now days.
And looking into the enormus production of
Whites it seams to be a lot of recycled designs,
a pot here a diode there, well that was rather coarse but 7-10 models of the 6000 DI pro only??
So what is actually new, does anyone have in-depth knowelege of detector design history? Dave perhaps, you have a interesting OTA patent!
Im interested in the design history to know
where different solutions "came new" and "when"
they went into industry practise in a time scale
of some sort.
