Abstract: A multi-layer composite fabric comprises a first woven layer having a plurality of warp yarns and plurality of weft yarns, a second woven layer having a plurality of warp yarns and plurality of weft yarns, and a third non-crimp layer disposed between the first woven layer and the second woven layer. The first woven layer can be joined to one or more of the following: the second woven layer and the third non-crimp layer.

Abstract: Systems and methods for connecting a plurality (even a large plurality) of recipients or destinations to an originating caller across, for example, a phone network. In preferred embodiments, the phones are connected within a single private branch exchange (PBX), which can be distributed across individual nodes over large distances. The size of the groups included in the destinations can be indefinitely large and can be configured to parse recipients as desired. In preferred embodiments, an originator selects from among various pre-defined groups (or, alternatively, the originator defines new groups) and initiates a one-way or two-way call to recipients. The recipients' control over refusing the announcement are optional, but preferably include non-override options so that emergency announcements may not be ignored or blocked.

Abstract: A method of operating a distributed call progress tone detection system. In one embodiment, the method includes: (1) receiving requests from an application over said packet network and transmitting transmit call and control processing commands to a switching partition via a main control unit, (2) providing an interface to corresponding access nodes via line interface modules, (3) generating a call on a first of said line interface modules, (4) employing an input-output distributor to interconnect a call progress tone detector and said first of said line interface modules to allow said call progress tone detector to perform a call progress tone detection analysis and generate an indication thereof with respect to said first of said line interface modules and (5) creating an interconnection between said first of said line interface modules and a second of said line interface modules based on said indication via said input-output distributor and notifying said application of said interconnection.
