    Abstract: One-axis and two-axis vibratory gyroscopes include a unitary resonator structure conceptually having four beams interconnected in a cross-hatch configuration. While each beam can be considered a unitary piece of material, each beam's attachment to two cross beams conceptually divides the resonant beam into a central section between the attachment points and two tail sections aft of the attachment points. The attachment points are preferably nodal points of the beam with respect to both a drive mode shape and a sense mode shape of the beam for the resonant mode in which the resonator is configured to operate. Thus, the location where two beams intersect is preferably a nodal point for both beams. The tail sections of each beam allow the resonant mode of the resonator to be carefully configured.

  • Patent number: 9461618
    Abstract: In one aspect of the invention, an acoustic device has a first coupled resonator filter (CRF) and a second CRF electrically coupled to one another in series. Each CRF has an input port, an output port, a bottom film bulk acoustic resonator (FBAR), an acoustic decoupler formed on the bottom FBAR, and a top FBAR formed on the acoustic decoupler. Each FBAR has a bottom electrode, a piezoelectric layer formed on the bottom electrode, and a top electrode formed on the piezoelectric layer. The decoupling layer capacitance arising between the two electrodes enclosing the acoustic decoupler in a CRF is configured to achieve targeted filter response. A compensating capacitance is introduced to improve the amplitude and phase imbalance performance of an unbalanced to balanced CRF by eliminating the existence of asymmetric port-to-ground or feedback capacitance at the balanced output port produced by the decoupling layer capacitance.

  • Patent number: 9371823
    Abstract: There is provided a polymeric actuator including: a pair of facing portions located so as to face each other; and a folded portion through which one end portions of the pair of facing portions are coupled to each other, wherein the pair of facing portions and the folded portion are composed of an inner electrode layer, an electrolyte layer, and an outer electrode layer which are laminated in order from an inside. Therefore, the displacements are generated in the pair of facing portions, respectively, to be added to each other, and the displacement is generated in the folded portion as well due to the bending. As a result, the large displacement is generated as a whole. Thus, it is possible to increase the displacement amount after the simplification of the structure is realized.
