  • Patent number: 7945924
    Abstract: A system and method is disclosed for detecting distribution of multimedia content. The volume level of data traffic is monitored for a plurality of users to select any users with high-bandwidth usage. The time of day and the day of the week may be considered when determining whether a user is a high-bandwidth user. Upon selecting a user as one with high-bandwidth usage, such user may be subject to packet inspections of data traffic streams. In some embodiments, content identification parameters or watermarks are added to one or more packets in a data traffic stream carrying multimedia content.

  • Patent number: 7941694
    Abstract: An asymmetric data mirroring method with a local storage device and a remote storage device being separated by large distances is disclosed. A server determines a predetermined time period associated with a round trip latency between the server and a remote storage device. The server submits a request to a local storage device, a remote storage device and a memory device disposed between the server and the remote storage device. The server submits additional requests to the local and remote storage devices during the predetermined time period. The server stores a copy of each request submitted by the server to the remote storage device in a memory disposed between the server and the remote storage device while the server waits for whether an acknowledgement associated with the request has been received from the remote storage device during the predetermined time period. The server resubmits the request and the additional requests to the remote storage device if the acknowledgement is not received.

  • Patent number: 7941110
    Abstract: A disclosed RF circuit includes a power amplifier that produces an RF output signal, a detector to generate a detector signal indicative of a power of the RF output signal, and an offset unit to produce an offset signal that indicates low supply voltage conditions. The power of the RF output signal is reduced, at least in part, by a control signal reflecting a combination of the detector signal and the offset signal. The circuit may include a transmitter to provide an RF input signal to the power amplifier. The transmitter may receive the control signal and adjust a power of the RF input signal based on the control signal. The detector may produce a control current indicative of the RF output signal power. The offset unit produces the offset signal based on a difference between the supply voltage and a nominal supply voltage value.

  • Patent number: 7912201
    Abstract: A method of providing a caller with a directory assistance dialog. The dialog is configurable, at any level of the dialog, from an automated speech recognition (ASR) dialog to an operator-assisted (OP) dialog. The dialog is handed off to an operator if any level of the speech recognition dialog fails. Also, a configuration switch may be set to cause the dialog to be handed off to an operator even if a response at some level of the ASR dialog is successfully recognized.

  • Patent number: 7911608
    Abstract: A new method and strategy for the quantitative determination of enantiomeric purity that combines polarimetry, spectroscopy, and chemometric modeling. Spectral data is collected after a light beam is passed through a first polarimeter, a sample of a chiral compound, and a second polarimeter oriented at a 45 degree angle relative to the first polarimeter. The spectral data for samples of known enantiomeric composition is subjected to a type of multivariate regression modeling known as partial least squares (“PLS-1”) regression. The PLS-1 regression produces a mathematical model that can be used to predict the enantiomeric composition of a set of samples of unknown enantiomeric purity.

  • Patent number: 7903790
    Abstract: A system and method for imputing data into a database includes an imputing system operable to impute data based on outside plant construction principles. The imputing system includes an inventory database, a data engine, a search engine, and a loop engine. The inventory database includes a plurality of distribution records each associated with one or more cable pairs. The data engine determines if a desired distribution record corresponding to a desired cable pair includes missing data. The search engine searches a known class of serving terminals for complete distribution records and iteratively searches a sized binder group within the inventory database for one or more complete distribution records where the size of the binder group searched increases with each iterative search. The loop engine determines an imputed value for the desired distribution record based on the searching and imputes the value into the desired distribution record.

  • Patent number: 7900249
    Abstract: A system, method and apparatus for securing communications between a trusted network and an untrusted network are disclosed. A perimeter client is deployed within the trusted network and communicates over a session multiplexing enabled protocol with a perimeter server deployed within a demilitarized zone network. The perimeter client presents requests to make available and communication initiation requests to the perimeter server which presents corresponding sockets to the entrusted network. The session multiplexing capabilities of the protocol used between the perimeter server and perimeter client permit a single communication session therebetween to support a plurality of communication sessions between the perimeter server and untrusted network. In the event data flows across the communication sessions are encrypted, decryption of the data flows is left to the components at the end points of the communication session, thereby restricting exposure of privileged information to areas within trusted networks.

  • Patent number: 7900153
    Abstract: Supply chain visualization and management are achieved using supply entity icons and inventory parameters overlaid on a zoomable map image. A user zooms in and zooms out to display multiple geographical areas and variably receives greater or less detail regarding supply parameters. A user may initiate a transfer of products between supply entities by manipulating icons on an output device to result in the generation and sending of business documents to relevant entities. A hypothetical mode allows a user to estimate the effects of potential product transfers on entities within the supply chain.
