Latest Patents
Among his latest patents is a method of determining the pen velocity along a graphic tablet. This invention relates to the determination of the velocity of a conductive pen along a graphic tablet. The technology generates successive pulses in conductors arranged in a regular pattern within the tablet, producing an electromagnetic signal in a conductive pen situated nearby. When the pen approaches the writing surface, the pen signal exhibits a local maximum, indicating the pen's location. The distance between the edges of this local maximum provides an indication of the pen's velocity. Another notable patent involves employing gray codes for pen detection. This graphic tablet includes parallel electrodes where a series of patterns is presented to determine the pen's position relative to the electrodes. The patterns allow for a short series of code elements to be formed on an electrode, which can be picked up by the pen, thus representing the relevant electrode.
