Abstract: A computer network management arrangement employs enhanced network elements that include database technology. This, in turn, allows such enhanced network elements to filter management information intelligently and also to notify an associated network manager of the occurrence of complex events of interest. More specifically, the network elements are enhanced through use of database technology to process declarative queries and to support triggers. Additionally, auxiliary network managers, that perform as proxies for network elements that have not been enhance with database technology, are employed to collect and integrate management information from one or more non-enhanced network elements. Consequently, the management information supplied to a network manager from the auxiliary network mangers could be significantly less than that collected from the network elements. Thus, the auxiliary network managers further reduce the network management traffic.

The resulting MEMs devices are advantageous for optical switching, variable attenuation and power gain equalization.

Abstract: In a switch in accordance with the principles of the present invention, switch modules that include a disassembly block, a switching core, and an assembly block are combined to implement an N×M multi-port switch that effectively connects N input ports to M output ports, provides broadcast capability, and may be non-blocking. The switch operates on data channels that all have their respective data blocks organized in the same number of bit-packs. Disassemblers within each module slice incoming data blocks into bit-packs and route the bit-packs to switching cores. A switching core within each module connects each input channel with each output channel at the bit-pack level. Assemblers within each module receive the switched bit-packs from each switching core and assemble the bit-packs into data blocks for each of the output channels.

Abstract: In accordance with the invention, the component layer, the spacer and the actuator layer of a MEMs device are assembled at ambient temperature and held together in lateral alignment by upper and lower magnets.

Abstract: The number of optical channels that may be used to transmit information/data is greatly enhanced using an optical transmission facility having a transmitter that outputs optical signals having respective wavelengths within a first bandwidth, e.g., the C band, combines the latter signal with an optical signal having a wavelength between the first bandwidth and a second bandwidth, e.g., the L-band, and, using a non-linear frequency converter, processes the combined signal to form at least optical signals having wavelengths within the second bandwidth that correspond with the wavelengths of the optical signals within the first bandwidth. In this way, equipment designed for the C band may also be used to process optical signals with another, second band.

Abstract: An optical fiber cleaner includes a base having a well supported within an annular section. An absorbent material, such as a sponge or cotton ball, may be located within the well of the base. A cover mates with the base and holds a wipe in a preferred position over the well. The cover includes an aperture through which the wipe may be accessed. The cover may also include a hinged element, or lid, that closes over the aperture within the cover when the cleaner is not in use. The base may itself be an element of the lid of a push-pump mechanism. In such case, the well within the base is operationally connected to receive solvents from the pumping mechanism and the pumping mechanism, including the base, forms a cover for a solvent reservoir, such as a non-reactive bottle.

Photodetectors coupled to the primary output and one or more of the secondary outputs provide feedback information for maintaining wavelength stability.

Abstract: Jargons are a family of application oriented languages well-suited for representing and processing complex, hierarchically structured information. A system is presented that automates most of the work of making a jargon, so practically any programmer can make a simple one in a few days. Every jargon has the same syntax, is processed with same ready-made base interpreter, and comes complete with a suite of “deluxe” features: debugger, error handler, function definition, associative arrays, variables, incremental loader, among others. The system provides a general purpose programming language for writing actions that defines the semantics of a jargon and an interpreter written in the general purpose language and customized for the jargon, by integrating the jargon's actions into the interpreter. Using jargons, the same information document may be reprocessed to generate a multiplicity of products.

Abstract: In accordance with the invention, an optical fiber array comprises a substrate providing a planar array of optical fibers. The optical fibers are parallel to an array axis, but the fiber ends present smooth, polished surfaces angled from the array axis to minimize return loss of light directed along the axis. Three embodiments are described. The first is a series of 1×n strip arrays each mounted at an angle to the array axis to form a saw tooth configuration faceplate. The holes in each strip are also angled to compensate for the angled mount. A second embodiment uses an angled planar faceplate having tapered holes. A third embodiment uses an angled faceplate planar with double-tapered holes to obtain the angled end surfaces. In each embodiment, the fiber ends are substantially coplanar with the faceplate surface but the ends are angled with respect to the array axis.

Abstract: A halo implant (42, 44) for an MOS transistor (10) is formed in a semiconductor substrate (12) at a shallow implant angle, relative to normal to the substrate surface (29). A polysilicon gate structure (32, 33) is formed over a gate oxide (28) and then a hard mask (70), such as a TEOS-generated layer of silicon oxide, is deposited on an upper surface (68) of the gate. The mask is etched with a blanket anisotropic etch to form a cap-shaped mask (72). The shape of the cap causes the dopant for the halo implant to penetrate to a depth which follows the contour of the cap. Thus, halo implants may be formed which extend under the gate structure without the need for large angle implants and resultant shadowing problems caused by adjacent devices.

Abstract: A method and apparatus for multiplexing and demultiplexing light signals of multiple wavelengths using two canceling dispersion stages with a stage between them which transforms the angular positions of the beams, the lateral positions of the beams, or both the angular and lateral positions of the beams. Light of multiple wavelengths is introduced through an input waveguide. The light then enters the first stage of the invention which disperses the signal. The dispersed signals then enter a second stage in which they are transformed. The transformed signals then enter a third stage where they are subject to the inverse of the dispersion performed in the first stage. In other words, if the third stage were placed immediately after the first stage, the third stage would nullify the dispersion of the first stage. However, adding the intervening transformation step results in only the simple linear dispersion being canceled in the system while the transformed part of the dispersion is retained.

Abstract: A limitation of a three-dimensional world in which objects in the distance may be represented in only two dimensions as a video on a screen is that when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, namely, any portion of the object that is no longer on the video screen disappears. To overcome this limitation, when an object within the field represented by the video undergoes a trajectory that takes it to a location in the world that is not represented by the video but instead is a location in the foreground which is represented by computer graphics, such an object, or portion thereof, is made to continue to be visible to the user by representing it at the foreground location to which its trajectory was carrying it using computer graphic techniques, rather than video.
