Abstract: Systems and methods for scheduling and delivering a message based on a recipient's time zone are provided. In this regard, a representative method, among others, includes receiving parameters that are associated with delivering a message to a recipient. The parameters include information associated with the recipient and the time and date associated with delivering the message. The message includes at least one of the following: text, visual, and audio data format. The method further includes determining a recipient's location based on the received parameters; determining a recipient's time zone based on the determined recipient's location; and scheduling delivery of the message based on the determined recipient's time zone.

Abstract: Acoustic wave devices employing shallow bulk acoustic waves rather than surface acoustic waves, to provide higher frequencies of operation and other significant advantages, such as less susceptibility to aging and less sensitivity to surface contamination. In each embodiment of the invention, a transmitting transducer and a receiving transducer are oriented on the surface of an anisotropic piezoelectric crystal to achieve substantial coupling of shallow bulk acoustic waves and essentially zero coupling of surface acoustic waves. In one embodiment of the invention, various types of grating filters utilize shallow bulk acoustic waves, and a set of parallel mechanical or electrical discontinuities at or near the surface of the crystal provide reflection of acoustic energy at a frequency determined by the spacing of the discontinuities. Uniformly spaced gratings provide bandpass filter operation, and gratings with graduated spacings provide for frequency compression or expansion.
