bringing together sets of actuators to create desired control effects. This approachinvolves coherent phase switching and modulation of a linear actuator array. A pair oflinear resonant actuators (LRAs) may be employed for improved haptic waveformsynthesis performance. According to one feature, energy may stored in the mechanicalinertia of the LRA via velocity and stiffness of the LRA via displacement and releasedthrough modulation of the relative phase of the LRAs. Phase switching and modulationtechniques may be used to control more than two LRAs, and in other arrangements thana dual LRA, including, but not limited to architectures that have LRAs arranged in multipledirections in a array spanning, for example, the two dimensions of a plane, or threedimensions of physical space.申请人：General Vibration Corporation地址：San Francisco CA US国籍：US代理机构：Botos Churchill IP Law LLP
