    • A power split transmission includes a rotatable input shaft, a rotatable output shaft, and a planetary gear assembly connected between the input shaft and the output shaft. The transmission also includes a first hydraulic unit operable as a pump or a motor, the first hydraulic unit being coupled to the output shaft via the planetary gear assembly; a second hydraulic unit operable as a pump or a motor, the second hydraulic unit being coupled to the output shaft independently of the planetary gear assembly; and a braking mechanism coupled to the input shaft that is selectively engageable to retard rotation of the input shaft in at least one direction. The braking mechanism enables the power split transmission to use both the first hydraulic unit and the second hydraulic unit to provide enhanced torque at the output shaft without damaging a prime mover coupled to the input shaft.

    • 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.

    • An acoustic resonator with improved quality factor and electro-mechanical coupling is disclosed. In one embodiment, the acoustic resonator includes an acoustic mirror formed on the top surface of a substrate or in the substrate, a first electrode having a end portion, formed on the acoustic mirror, a piezoelectric layer formed on the first electrode; and a second electrode formed on the piezoelectric layer, where at least one of the first electrode and the second electrode and the piezoelectric layer define a gap in a region that overlaps the end portion of the first electrode. In one embodiment, a dielectric film is deposited on the surface of the end portion of the first electrode to form completely planarized surface before the piezoelectric layer deposition. In another embodiment, a gap between the second electrode and the piezoelectric layer, so that the piezoelectric coupling in the end portion area of the first electrode is minimally contributed into the whole resonator.
