Abstract: The object of the invention is to provide an optical filtering system which can utilize wide angle optics and still maintain a very narrow pass band. A filtering system (100) is disclosed for receiving and bandpass filtering free space optical signals. The filtering system (100) includes a compound parabolic concentrator (110) with a small aperture for accepting the free space optical signals (115) and a larger aperture whereby the optical signal (115) exits. The compound parabolic concentrator (110) has a reflective coating on the inner surface to reflect incident optical signals (115) to produce a substantially collimated signal beam. The collimated signal is further passed through a narrow, bandpass filter (140) before detection by a photodetector device (150). In an alternative embodiment, a compound hyperbolic concentrator (310) is utilized to reflect the incident optical signals and produce a substantially collimated signal beam.

Abstract: A method for making essentially crack free large cross section ceramic articles by injection molding techiques comprises the use of from about 0.1 v/o to about 10 v/o fibers with the ceramic injection molding formulation followed by the injection molding, binder removal and densification steps to form an essentially crack free densified large cross section ceramic article. The fibers are softened prior to the onset of densification and incorporated into the ceramic intergranular phase. This process eliminates the component distortion during densification which would have occurred if the fibers remained in the component.

Abstract: A silicon nitride-cordierite article, and process for fabricating. The silicon nitride imparts a high mechanical strength, and the cordierite contributes to a lower thermal conductivity making the composition especially useful for internal parts of a diesel engine. The mechanical strength can be increased by crystallizing the continuous cordierite glassy phase of the article. Crystallization of the continuous cordierite glassy phase is accomplished by the addition of a nucleating agent such as zirconium dioxide in the formulation and a subsequent reheating step after densification.

Abstract: Management packets (36, 52, 54) are defined that are modified in the payload by each node (16, 18, 20; 24, 26, 28) along a virtual connection and are used to measure both end-to-end QoS and specific individual intermediate node performance parameters. Management packets (36, 52, 54) are implemented by defining entirely new packets or by modifying ATM OAM cells. Switches or routers for use as intermediate nodes are defined that modify the payload of the management packet (36, 52, 54) and locally measure packet delay and packet loss. An intermediate node measures and records the difference between the arrival and departure times of management packets (36, 52, 54) at that switch (31. 56) utilizing delay-stamp fields within the management packets (36, 52, 54) and either the switch internal routing header or timestamp fields (9) within the packet. At the endpoint of the virtual connection, delay-stamp fields (10) in the management packet (36, 52, 54) indicate individual node delays and the cumulative delay.

Abstract: A method and apparatus for visually or audibly indicating to a served party that messages are waiting (165) on a telephone network-based message accumulation system such as voice mail, FAX store-and-forward, and other telecommunications devices (110). In one embodiment of the invention, the method is utilized in conjunction with a telephone network-based voice mail system or other telephone network-based message accumulation system. The invention is accomplished through the use of auxiliary computer systems (120) which are associated with single or multiple central office switching systems (105). Existing single pair telephone wiring is utilized to couple the telecommunications device (110) and the message waiting indicator apparatus (165) to the telephone network (135), and thus no additional wiring requirements are needed.

Abstract: A novel system for performing optical time domain reflectometry (OTDR) measurement on a plurality of optical fibers (105, 106, 107, 108, 109), using only the transmitters and receivers of the system data. The system uses optical line cards (120, 121, 122, 123, 124), which are normally used for transmission of system data, to perform fault detection. Detection of a fault in an optical fiber causes the line card associated with the fiber to stop transmission of system data and alert signal processor (140) to initiate OTDR testing. The signal processor is coupled to each of the line cards through an electronic 1XN switch (130) so that each fiber can be tested individually.

Abstract: A method of producing crack free ceramic parts having large cross-sections is disclosed. An initial mixture of ceramic powder containing a binder and from 0.1 v/o to 10 v/o of whiskers or fibers which are made of carbon, graphite or high temperature melting or decomposition point organic polymers. The mixture is either injection molded or slip cast to form a shaped article. The shaped article is heated in a nitrogen atmosphere to a temperature of 450 DEG C and then in an atmosphere of air at a temperature of 450 DEG C to 600 DEG C to completely remove the binder. The resulting binderless shaped article is then heated at 800 DEG C for a period of time sufficient to completely remove the whiskers or fibers from the shaped articles. The article is then encapsulated in glass and hot isostatically pressed at a pressure of 30,000 psi to densify the article to approximately 99 % of theoritical. The resulting article has a complex geometry and a large cross-section but without detrimental cracks.
