  • Braking characteristic detection system for haptic actuator
    Patent number: 10304298
    Abstract: An actuator evaluation system evaluates one or more characteristics of an actuator usable as a haptic output device. The system can detect an optimal braking frequency of a drive signal that enables the actuator to provide a desired haptic effect in response thereto. The system sequentially applies a plurality of drive signals having different frequencies to the actuator and analyzes acceleration of the actuator to determine a drive signal that results in the desired braking performance.
    Type: Grant
