发明名称 Motion-responsive coupled masses
摘要 In some embodiments, an apparatus and a system, as well as a method and an article, may include coupling a plurality of masses to provide a plurality of output signals responsive to motion relative to a common axis. Moving the plurality of masses at a substantially common frequency, moving a subset of the plurality of masses out of phase with the remainder of the plurality of masses, and combining the plurality of output signals to provide a combined signal associated with a response property of at least one of the plurality of masses may also be included.
