Abstract: An acoustic resonator is fabricated by bonding a first piezoelectric plate to a substrate and spans locations for a first and second cavity in the substrate. A top surface of the first piezoelectric plate is planarized to a first thickness. A bonding layer is formed on the first piezoelectric plate and spans the first and second cavity locations. A second piezoelectric plate is bonded to the bonding layer and spans the first and second cavity locations. A portion of the second piezoelectric plate spanning the second cavity location is etched away to form a first membrane over the first cavity location and a second membrane over the second cavity location. Interdigital transducers are formed on the first and second membranes over the first and second cavity location to form a first and second resonator on the same die.

Abstract: Band N77 bandpass filters include a first plurality of transversely-excited film bulk acoustic resonators (XBARs) on a first chip comprising a first rotated YX-cut lithium niobate piezoelectric plate having a thickness less than or equal to 535 nm, and a second plurality of XBARs on a second chip comprising a second rotated YX-cut lithium niobate piezoelectric plate having a thickness greater than or equal to 556 nm. A circuit card is coupled to the first chip and the second chip. The circuit card includes conductors for making electrical connections between the first chip and the second chip.

Abstract: System and method for downloading portions of a remotely located network object to produce a completely downloaded local copy of the network object. The system and method include and involve a server facility and a software delegate. The server facility is configured to store and to serve the software delegate and a network object. The server facility is further configured to be accessed by a client via an electronic data network, such as the Internet and WWW. The software delegate can reside and be executed on a client, and is configured to control the downloading of portions of a network object from the server facility to the client via the electronic data network, until a completely downloaded copy is stored locally on the client.

Abstract: A thin flexible handle for carrying a bag in which the gripping portion of the handle is separated from respective legs by a gap having a surface having a radius of curvature sufficient to provide the handle with resistance to tearing.
