Abstract: A method and apparatus for maintaining packet order integrity in a switching engine wherein inbound packets are forwarded to different ones of parallel processing elements for switching. Order preservation for packets relating to the same conversation is guaranteed by checking for each inbound packet whether a previous packet from the same source is pending at a processing element and, if the check reveals that such a packet is pending, forwarding the inbound packet to the same processing element as the previous packet.

Abstract: A multi-service network switch capable of providing multiple network services from a single platform. The switch incorporates a distributed packet forwarding architecture where each of the various cards is capable of making independent forwarding decisions. The switch further allows for dynamic resource management for dynamically assigning modem and ISDN resources to an incoming call. The switch may also include fault management features to guard against single points of failure within the switch. The switch further allows the partitioning of the switch into multiple virtual routers where each virtual router has its own wet of resources and a routing table. Each virtual router is further partitioned into virtual private networks for further controlling access to the network. The switch supports policy based routing where specific routing paths are selected based on a domain name, a telephone number, and the like.

Abstract: Provided are methods of manufacturing an electrostatically clean solar array panel and the products resulting from the practice of these methods. The preferred method uses an array of solar cells, each with a coverglass where the method includes machining apertures into a flat, electrically conductive sheet so that each aperture is aligned with and undersized with respect to its matched coverglass sheet and thereby fashion a front side shield with apertures (FSA). The undersized portion about each aperture of the bottom side of the FSA shield is bonded to the topside portions nearest the edges of each aperture's matched coverglass. Edge clips are attached to the front side aperture shield edges with the edge clips electrically and mechanically connecting the tops of the coverglasses to the solar panel substrate. The FSA shield, edge clips and substrate edges are bonded so as to produce a conductively grounded electrostatically clean solar array panel.

Abstract: The present invention discloses an interactive infant or child blanket with a tactile apparatus for removably attaching small toys such as pacifiers, teethers, rattles, and developmental toys. The invention also includes an apparatus for removably attaching the blanket itself to other objects such as a highchairs, baby bouncers, infant swings, car seats, strollers, or shopping carts, for play control and stability. The novel attachment system allows a child to play on the go without the hassle of dropping or soiling play objects, thereby minimizing the chance of loss or exposure to germs. The blanket preferably comes packaged in a matching bag that can also carry toy attachments and perhaps a bottle and/or diapers, providing parents with a small “baby to-go” bag for quick errands and trips. In another embodiment, the retention blanket includes a blanket adapted to engage a wheelchair as required by elderly and handicap persons.

Abstract: A switching device for forwarding network traffic to a desired destination on a network, such as a telephone or computer network. The switching device includes multiple ports and uses a lookup table containing lookup keys to determine which port to forward network traffic over. The lookup table includes disparate forwarding databases that contain database entries in different formats. For example, one forwarding databases may relate to MAC addresses, while another database relates to IP addresses. The disparate databases are maintained in a single lookup table and a binary search engine searches the table without regard to the database format. Like-kind database entries are grouped within the lookup table and the lookup table is maintained in sorted order by prepending format identification bits to the lookup keys. Memory availability for the disparate databases can be dynamically changed allowing customization for a particular user application.

Abstract: A laser diode driver circuit is disclosed that uses a cascode output stage having high-impedance load and a matching network for reducing mismatch interference. Due to the high-impedance load, on-chip dummy current is less than that required for laser diode drivers with matched loads. Accordingly, the number of transistors of said output stage can be reduced. Moreover, with an AC-coupled active load circuit replacing the matched resistance of the matching network, the power efficiency is improved. A laser diode driver circuit, in accordance with the present invention, can be applied to an optical transmitter with low power requirement.

Abstract: A system and method for receiving calls for a plurality of persons. The system receives an incoming telephone call at a communications host, such as a PBX, from a caller for called person and queries a database for a set of information regarding the called person. The database can include information for each individual supported by present invention. The system can then query the status of the called person's phone line and announce to the caller some information regarding the called person. The system then forwards the incoming telephone call, the status of the called person's phone line, and the set of information regarding the called person to a display screen of a human secretary, who then answers the incoming telephone call.

Abstract: The disclosed invention mounts transmitting and receiving electrical coils (52, 54) within channels or chambers (48, 50) formed by the notched ends of magnets (24, 28) closest to the metallic structure under test (40) where said magnets (24, 28) are arranged to form annular arrays (20, 22) of an electromagnetic acoustic transducer (EMAT) pair applicable in non-destructive testing. The detection of one or more electromagnetically-induced resonant frequencies at shifted locations indicates the presence of one or more flaws (58, 60) in the metallic structure under test (40). The novel recessed mounting of the coils provided by the channels or chambers (48, 50) substantially reduces the observed electrical cross-talk between coils (52, 54) over the prior art and reduces the likelihood of the coils (52, 54) making contact with the subject metallic structure under test (40) as it is in longitudinal motion relative to the coils (52, 54).

Abstract: Data compression method, system, and program code for compressing antenna pattern data generated by measuring the complex voltage derived from the interaction of a RF waveform and a sensing element are disclosed. The antenna pattern data are modeled with a plurality of infinitesimal antenna elements, each element defined in terms of a distinct position, orientation, and polarization. An analytical expression for the interaction between the plurality of infinitesimal antenna elements and an impinging waveform yields a plurality of expressions for a theoretical voltage. The plurality of infinitesimal antenna elements constitute a mathematical basis set from which a weighted linear combination is constructed. The value of the weights are determined by equating the complex voltage representing the antenna pattern data with the theoretical voltage representing the plurality of weighted infinitesimal antenna elements.
