Using the impedance probe and Z-width plots combined with virtual stiffness-damping plots, I show that added active electrical damping improves the performance of the haptic display.information, the voltage generated by the sensing coil is amplified before sampling. ... approximately 1010 ohms, of the INA129 instrumentation amplifier is used to restrict current flow though the sensing coil. ... The two pairs of connection wires between the amplifiers and the voice coils, one set for each coil, are each twisted pair to ... Manual Switch double duplicate encoder signal drop with 100 ohm 139.
