Abstract: Embodiments of an acoustically-coupled transformer have a first stacked bulk acoustic resonator (SBAR) and a second SBAR. Each of the SBARs has a lower film bulk acoustic resonator (FBAR) and an upper FBAR, and an acoustic decoupler between the FBARs. The upper FBAR is stacked atop the lower FBAR. Each FBAR has opposed planar electrodes and a piezoelectric element between the electrodes. The piezoelectric element is characterized by a c-axis. The c-axes of the piezoelectric elements of the lower FBARs are opposite in direction, and the c-axes of the piezoelectric elements of the upper FBARs are opposite in direction. The transformer additionally has a first electrical circuit connecting the lower FBAR of the first SBAR to the lower FBAR of the second SBAR, and a second electrical circuit connecting the upper FBAR of the first SBAR to the upper FBARs of the second SBAR.

Abstract: An apparatus including vertically separated acoustic resonators are disclosed. The apparatus includes a first acoustic resonator on a substrate and a second acoustic resonator vertically separated above the first acoustic resonator. Because the resonators are vertically separated above another, total area required to implement the resonators is reduced thereby savings in die size and cost are realized. The vertically separated resonators are supported by standoffs that are fabricated on the substrate, or on a resonator.

Abstract: The band-pass filter has a stacked pair of film bulk acoustic resonators (FBARs) and an acoustic decoupler between the FBARs. Each of the FBARs has opposed planar electrodes and a layer of piezoelectric material between the electrodes. The acoustic decoupler controls the coupling of acoustic energy between the FBARs. Specifically, the acoustic decoupler couples less acoustic energy between the FBARs than would be coupled by direct contact between the FBARs. The reduced acoustic coupling gives the band-pass filter desirable in-band and out-of-band properties.

Abstract: An improved curtain wall casing bead for installation on buildings having stucco or similar curtain wall exteriors. The improved curtain wall casing bead incorporates a mesh attached to at least the base portion of the casing or starter bead, which mesh extends beyond the front edge of the base, and, when folded upward over the face of an inserted foam or curtain wall panel, provides additional area for the infiltration of over-applied stucco finishes or the like. Such additional infiltration, after drying of the over-applied layer provides a more adherent, higher quality and more durable attachment of the stucco finish to the casing bead and the overall wall structure is achieved.

Abstract: The piezoelectric isolating transformer is characterized by an operating frequency range and includes a resonant structure having at least one mechanical resonance in the operating frequency range. The resonant structure has an insulating substrate, a first electro-acoustic transducer and a second electro-acoustic transducer. The substrate has a first major surface and a second major surface opposite the first major surface. The first electro-acoustic transducer is mechanically coupled to the first major surface. The second electro-acoustic transducer is mechanically coupled to the second major surface. One of the transducers is operable to convert input electrical power in the operating frequency range to acoustic energy that excites mechanical vibration in the resonant structure. The other of the transducers converts the mechanical vibration to output electrical power.

The host/data controller also interleaves data on a plurality of channels associated with each of the plurality of memory modules. The system implements error interrupt control, ECC error reporting, cartridge error power down procedures in response to command errors, storage of error information in unused segments of each DIMM, hot-pug procedure indicator and remote tagging capabilities of memory cartridges and DIMMs.

Abstract: Easy to assemble and disassemble tables have continuous frame members with at least two tapered sockets which support table legs. The continuous frame members are identical and thus can be used interchangeably as table bases and table top supports. The center of each taper within the continuous frame member is in the same position. Tapered sockets within each frame member insure that legs inserted into those sockets are parallel to one another. The parallelity of the table legs is further enhanced by inserting the other end of the table leg into a corresponding frame member in which the tapers are identically spaced. The tables are easy to assemble by inserting the tapered table legs into the “self-holding” tapered sockets in the frame members. Easy disassembly of the tables is facilitated by quick release mechanisms which press the end of the leg seated in the socket to displace the leg from the socket.

Each of the DSBARs has a lower film bulk acoustic resonator (FBAR), an upper FBAR and an acoustic decoupler.
