Latest Patents

One of her latest patents is the "Digitizer cursor velocity offset error correction system." This invention addresses the issue of velocity-induced offset errors in digitizing systems when a cursor is moved diagonally across a sensing grid. The system reduces the offset error between the actual and depicted cursor position, especially when a pen cursor is moved rapidly over a digitizing screen. It achieves this by forming a triplet of data through averaging samples from different axes, thereby enhancing positional accuracy.

Another notable patent is the "Dynamically-adjustable scanning rate in digitizers." This invention provides methods and apparatus for setting the signal-sampling period of each grid wire in a digitizing tablet. By adjusting the sampling period based on the cursor's speed, the invention minimizes jitter and signal errors associated with both stationary and rapid cursor movements. This method can also be applied to other positional determination devices, showcasing its versatility.
