Abstract: A gaming controller, comprising: a haptic actuator; and a haptic driver, wherein the haptic driver is configured to drive the haptic actuator with a drive signal having a dominant frequency F2, and to control how the drive signal is applied to the haptic actuator to generate a haptic effect that at least partly emulates a desired haptic effect having a dominant frequency F1, where F2>F1.

Abstract: A method for minimizing undesired movement of a moving mass of an electromagnetic load may include detecting undesired movement of the moving mass based on real-time measurements of one or more parameters associated with the electromagnetic load and, responsive to detecting undesired movement of the moving mass, affecting a signal applied to the moving mass to reduce the undesired movement.

Abstract: A method may include measuring an electrical parameter of an electromagnetic load having a moving mass during the absence of a driving signal actively driving the electromagnetic load, measuring a mechanical parameter of mechanical motion of a host device comprising the electromagnetic load, correlating a relationship between the mechanical parameter and the electrical parameter, and calibrating the electromagnetic load across a plurality of mechanical motion conditions based on the relationship.

Abstract: According to embodiments described herein, there is provided methods and apparatus for providing a driving signal to a transducer, wherein the driving signal is output by an amplifier. A method comprises receiving an indication of a voltage and a current of the driving signal; based on an electrical model of the transducer and the voltage and the current of the driving signal, estimating an estimated electrical response of the transducer representative of movement of a mass in the transducer; comparing the estimated electrical response to a desired electrical response; and controlling the driving signal based on the comparison.
