Abstract
Official abstract text for this publication.
A system that generates a haptic effect generates a drive cycle signal that includes a drive period and a monitoring period. The drive period includes a plurality of drive pulses that are based on the haptic effect. The system applies the drive pulses to a resonant actuator during the drive period and receives a signal from the resonant actuator that corresponds to the position of a mass in the actuator during the monitoring period.
First claim
Opening claim text (preview).
What is claimed: 1. A method of controlling an actuator having a resonant frequency, the method comprising: generating a haptic effect drive signal that comprises a drive period and a monitoring period, wherein the monitoring period comprises receiving an output signal from the actuator, the output signal comprising back electromagnetic field (EMF) of the actuator; during the drive period, applying one or more drive signal pulses to the actuator, measuring a zero crossing time o…
