Patent 9874966 was granted and assigned to Microsoft on January, 2018 by the United States Patent and Trademark Office.
Devices are described herein that include spaced electrodes. In one example, a spaced distance between the electrodes may cause a capacitance between the electrodes to exceed a capacitance threshold. In another example, an impedance component (e.g., a resistor or a capacitor) may be coupled between the electrodes. In accordance with this example, the impedance component may provide an impedance that is less than an impedance threshold while causing an absolute difference between voltages that are induced by the respective electrodes to exceed a voltage threshold.
