Abstract
A method for controlling haptic feedback in an electronic device, in some embodiments, comprises: generating a series of braking pulses to stop vibrations generated by a vibration motor in the electronic device; during a high impedance period between at least one pair of pulses in said series of braking pulses, determining a rate of change of an induced voltage associated with the vibration motor; and if said rate of change meets a requirement, ceasing said generation of the series of braking pulses.
