TDR Posted June 2, 2009 Share Posted June 2, 2009 Does anyone know about wacom stylus uded in tablet pcs, I got one and it doesnt have the original Stylus, I tried a different one but it doesnt work, It says a digitizer technology is used, I need to know how it work, so I can try to build an alternative. ;) can any1 give me a clue?

N1LL0 Posted June 2, 2009 Share Posted June 2, 2009 From the intertubes.... HOW THE WACOM CORDLESS, BATTERYLESS PEN WORKS. The Wacom stylus looks and feels like a pen yet contains no batteries or magnets. Instead it takes advantage of patented resonance technology developed by Wacom Co. Ltd. in which a tiny signal is sent to the stylus and returned for position analysis. In operation, a grid of wires below the screen alternates between transmit and receive modes about every 20 microseconds. In the transmit mode (1), the tablet's signal stimulates oscillation in the coil-and-capacitor resonant circuit in the pen. In receive mode (2), the energy of the resonant circuit oscillations in the pen is detected by the tablet's antenna grid. This is then analyzed to determine position and other information including pressure. Since the grid provides the power to the pen through resonant coupling, no batteries are required. Thus there are no consumables inside the pen that will run down and need to be replaced or that would make the pen top-heavy. A simple analogy for this patented technology is that of a piano tuner using a tuning fork to tune a piano. As the tuning fork is brought into proximity of the appropriate vibrating piano string (if the fork is of the same frequency) it will begin to borrow energy from the vibrating string and resonate, generating a tone. In much the same way, as the Wacom pen comes close to the tablet surface, it begins to resonate, generating its own frequency back to the tablet. When it hears the pen, it tracks the pen's location with unprecedented accuracy. The tablet then sends location, pressure and tilt information to the computer along with a signal indicating whether the pen point or the eraser tip is being used.

Thank you verymuch, Bit complicated thing.... Hmm... he he Quote Link to comment Share on other sites More sharing options...
manuel Posted June 5, 2009 Share Posted June 5, 2009 Thank you verymuch, Bit complicated thing.... Hmm... he he More so... It's not likely that you can "build" a replacement. You may have to purchase one. Quote Link to comment Share on other sites More sharing options...
TDR Posted June 8, 2009 Author Share Posted June 8, 2009 More so... It's not likely that you can "build" a replacement. You may have to purchase one. Hmm yaa I guess so.. he he. I allways try to build an replacement before I buy smthing. But this is complected... much much complicated.. :( he he,... Thanx for the help guys.
