Latest Patents
Hulls' latest patents include the "Polyphase Digitizer" and "Absolute Position Coordinate Determining Device Employing a Single Phase." The Polyphase Digitizer patent describes a two-dimensional digitizing system that utilizes two systems at right angles to each other. This system comprises conducting grid structures with terminals A, B, and C, which allow for precise cursor positioning through induced voltages. The voltages are phase-shifted and summed to provide accurate signals corresponding to the cursor's position along the X and Y axes. The system is versatile and applicable to various polyphase systems.
The Absolute Position Coordinate Determining Device patent outlines a two-dimensional digitizing system that employs at least two conducting grid systems. These systems generate voltages that vary cyclically as an AC excited cursor coil moves. The design allows for non-ambiguous absolute positioning of the cursor coil on a digitizer tablet, enhancing the precision of digitizing applications.
