    Abstract: A bulk acoustic wave device includes an acoustic decoupler between first and second film bulk acoustic resonators (FBARs). The first FBAR is resonant at a resonant frequency of the device and includes first and second planar electrodes abutting opposite sides of a first resonator volume free of any intervening electrodes and containing piezoelectric material disposed for acoustic vibrations parallel to a propagation axis normal to the first and second electrodes. The first FBAR has a first electrical impedance parallel to the propagation axis. The second FBAR is resonant at the resonant frequency and includes third and fourth planar electrodes abutting opposite sides of a second resonator volume free of any intervening electrodes and containing piezoelectric material disposed for acoustic vibrations parallel to the propagation axis. The second FBAR has a second electrical impedance parallel to the propagation axis and different from the first electrical impedance.

    Abstract: A technique for producing a scent from a hand-held device involves receiving a scent mixture formula at a hand-held device, converting the scent mixture formula into dispense control signals, and generating a scent mixture in response to the dispense control signals, the scent mixture being generated from different base scents that are individually stored within the hand-held device. In an embodiment, the scent mixture formula includes a scent identifier and a scent quantifier related to each base scent that is used to generate the scent mixture. Mixing multiple base scents to generate scent mixtures greatly expands the range of different scents that can be generated at a hand-held device that stores a limited number of base scents. Further, encoding a scent mixture into a scent mixture formula enables scent mixtures to be easily shared between hand-held devices.

    Abstract: An electronic device. The electronic device includes a first electrode and a coating layer. The electronic device is fabricated on a substrate; the substrate has a cavity created in a top surface of the substrate; and the first electrode is electrically coupled to the substrate. The coating layer coats at least part of a substrate surface in the cavity, and the presence of the coating layer results in a mitigation of at least one parasitic leakage path between the first electrode and an additional electrode fabricated on the substrate.
