1. A method comprising:
- transmitting an actuator signal to an actuator coupled to a surface of a device, the actuator signal configured to cause the actuator to output a force to the surface;
receiving a response of the surface to the force;
determining a resonant frequency of the surface based at least in part on the response; and
outputting a signal indicative of the resonant frequency.

Abstract
Systems and methods for resonance detection are disclosed. For example, one method for resonance detection includes the step of transmitting an actuator signal to an actuator coupled to a surface of a device. The actuator signal is configured to cause the actuator to output a force to the surface. The method further includes the steps of receiving a response of the surface to the force; determining a resonant frequency of the surface based at least in part on the response; and outputting a signal indicative of the resonant frequency.
