1. An apparatus, comprising:

  • a first electro-mechanical device, the first electro-mechanical device having a first end portion and a second end portion, the first end portion of the first electro-mechanical device being fixedly coupled to a base member, the first electro-mechanical device being configured to operate in a plurality of resonant modes;

    a second electro-mechanical device, the second electro-mechanical device having a first end portion and a second end portion, the first end portion of the second electro-mechanical device being fixedly coupled to a base member, the second electro-mechanical device being configured to operate in a plurality of resonant modes;

    a first mass coupled to the second end portion of the first electro-mechanical device; and

    a second mass coupled to the second end portion of the second electro-mechanical device, the first electro-mechanical device and the second electro-mechanical device being configured collectively to operate in a plurality of operational modes, each operational mode from the plurality of operational modes being uniquely associated with at least one of a resonant mode from the plurality of modes for the first electro-mechanical device and a resonant mode from the plurality of modes for the second electro-mechanical device.
