  • Patent number: 6108005
    Abstract: Methods, devices and systems are provided which produce a synthesized stereoscopic image of a source image by forming at least two images from a source image where at least one image has been modified relative to the source image such that the images have a different spacial appearance than each other. A wide variety of modifications may be made to the source object in order to form modified stereo images. These modifications may involve modifying one or more images relative to the source image. For example, at least one image may be magnified, reduced, or rotated in the X, Y and/or Z plane relative to the source image. Alternatively or in addition, the position of one or more elements of one of the images may also be changed relative to the source image. Alternatively or in addition, at least one of the images may be transformed relative to the source image using a function which alters the position of elements of the image along the X or Y axis relative to the source image.

  • Patent number: 6089894
    Abstract: An automatic insertion connector device, for instance for use in a test environment, particularly for connection to an RJ45 type connector. The connector has a contact portion having the general form of a connector part arranged to match the connector part it is intended to connect to, and is resiliently mounted by way of being carried on resilient material on a carrier means. The resilient mounting permits some deviation from the rest position in relation to the carrier and therefore enables account to be taken of deviation from the expected location of the parts under test.

  • Patent number: 6088368
    Abstract: The present invention provides a facility transport system for transporting Ethernet over digital subscnber lines. The system, termed 10BaseS, is capable of transmitting 10 Mbps Ethernet over existing copper infrastructure. The system utilizes carrierless amplitude modulation/phase modulation (CAP), a version of suppressed carrier quadrature amplitude modulation (QAM). The 10BaseS transport facility can deliver symmetrical data at approximately 13 Mbps (net 10 Mbps) over the unscreened, twisted pair telephone wires originally intended for bandwidths between 300 Hz and 3.4 KHz. The system utilizes frequency division multiplexing (FDM) to separate downstream channels from upstream channels. FDM is also used to separate both the downstream and upstream channels from POTS signals. The downstream and upstream data channels are separated in frequency from bands used for POTS and ISDN, enabling service providers to overlay 10BaseS on existing services.

  • Patent number: 6084873
    Abstract: The present invention allows telephone subscriber loops carrying data traffic between computer systems to be switched to an alternative connection through a data network, thereby unloading data traffic from the telephone network. The invention operates by means of a break switch, which selectively switches a plurality of subscriber loops between a central office switching system and a data network. The break switch is coupled to a concentrator which takes a plurality of inputs from the break switch and connects them to a smaller number of modems in a modem pool. The concentrator allows a subscriber line to connect to different types of modems within the modem pool, depending upon requirements of a particular subscriber line user. The modem pool connects through a network interface to a packet-switched network, such as the Internet. A number of different methods can be used to transmit a command to switch a subscriber loop from the central office switching system to the packet-switched network.

  • Patent number: 6030787
    Abstract: A hybridization assay is provided which uses an oligonucleotide probe which includes a fluorescent reporter molecule and a quencher molecule capable of quenching the fluorescence of the reporter molecule. The oligonucleotide probe is constructed such that the probe exists in at least one single-stranded conformation when unhybridized where the quencher molecule is near enough to the reporter molecule to quench the fluorescence of the reporter molecule. The oligonucleotide probe also exists in at least one conformation when hybridized to a target polynucleotide where the quencher molecule is not positioned close enough to the reporter molecule to quench the fluorescence of the reporter molecule. By adopting these hybridized and unhybridized conformations, the reporter molecule and quencher molecule on the probe exhibits different fluorescence signal intensities when the probe is hybridized and unhybridized.

  • Patent number: 6032218
    Abstract: A configurable weighted round robin arbitration mechanism adapted to receive as input a vector of order N, wherein each bit in the vector represents the eligibility of a queue or other source of data to participate in the arbitration process. A bit set to `1` in the vector indicates that the corresponding queue is eligible to participate in the arbitration process. Conversely, a bit set to `0` in the vector indicates that the corresponding queue is not eligible to participate. The arbitration process of the present invention enables a user to assign each queue (which corresponds to one of the bits in the vector) an individual weight. This results in a modified vector that represents the incoming vector after being handled by the weighting process. By giving each bit in the vector a weight, the user can control the probability of each bit, i.e., queue, being selected in the arbitration process.
