Abstract: A touch-sensitive glass barrier has a conductive coil affixed to the first side of a glass barrier, a capacitor connected to the conductive coil to form a resonator, and an inductance-to-digital converter (LDC) connected to drive an alternating current through the resonator. The LDC determines whether a conductive target has touched the second side of the glass barrier at a point opposite the conductive coil; and responsive to determining that the conductive target has touched the second side of the glass barrier at the point, provides a signal.
