Latest Patents

William D Greason holds a patent for a display system. This system consists of an array of blocks, with each block containing rows and columns of individual display units. Each unit features a thin, pivotally mounted vane that can be moved between an upright (WRITE) position and a horizontal (ERASE) position using electrostatic forces. The design allows for the display of messages by selecting patterns of vanes that are moved from one position to another. The vane assemblies are symmetrically bistable, enabling movement in both directions through the same triggering electrodes. These electrodes are activated by a short pulse of high D.C. voltage, which initiates the movement of the vane. The system also includes inhibit electrodes that prevent the movement of non-selected units, allowing for precise control over which vanes are activated.
