  • Patent number: 7424048
    Abstract: A receiver circuit processes a received signal to determine information regarding a guard interval therein. The receiver circuit typically forms digital samples from the received signal; generates a correlation function with peaks at positions that are determined by the size of the guard interval and a position of the guard interval within the received signal. The receiver circuit includes one or more comb filters, each corresponding to a possible guard interval size, each receiving a series of locations at which the correlation function exceeds a predetermined threshold, and each producing an output that provides information about the guard interval size and/or position. This advantageously allows the receiver circuit to determine the guard interval size quickly, for example, even in the case of received signals with relatively low signal-noise ratio.

  • Patent number: 7421389
    Abstract: A system and method for remote speech recognition includes one or more customer premise equipment, a speech engine, and a communication engine. The customer premise equipment interfaces with a host from which the customer premise equipment is remotely located. The speech engine, remotely located from the host, recognizes a plurality of speech spoken by a user of the customer premise equipment and translates the speech into the language of the host. The speech engine further converts the recognized speech into one or more text data packets where the text data packets include the recognized speech as data instead of voice. The communication engine encrypts the text data packets and transmits the text data packets to the host. Transmitting data instead of voice to the host reduces the computational demands on the host. Additionally, the communication engine receives a plurality of information from the host.

  • Patent number: 7418095
    Abstract: A system and method for providing customer activities while in queue allows for one or more customers to interact with one or more customer activities while waiting to speak with a live agent. The customers engage the customer activities while holding in a queue where the customer activities reduce the boredom, frustration, and perceived hold duration associated with holding to speak to a live agent. The customers are offered one or more options of the customer activities to interact with and the system and method monitors the customers' selections and interaction with the customer activities. As agents become available, each customer is transferred to an agent along with information regarding the customer's interaction with a selected customer activity. Upon completion of the interaction between the agent and the customer, the customer has the option to return to the selected customer activity and continue interacting with the selected customer activity.

  • Patent number: 7364969
    Abstract: A semiconductor fabrication process includes forming polysilicon nanocrystals on a tunnel oxide overlying a first region of a substrate. A second dielectric is deposited overlying the first region and a second region. Without providing any protective layer overlying the second dielectric in the first region, an additional thermal oxidation step is performed without oxidizing the nanocrystals. A gate electrode film is then deposited over the second dielectric and patterned to form first and second gate electrodes. The second dielectric may be an annealed, CVD oxide. The additional thermal oxidation may include forming by dry oxidation a third dielectric overlying a third region of the semiconductor substrate. The dry oxidation produces a interfacial silicon oxide underlying the second dielectric in the second region. An upper surface of a fourth region of the substrate may then be exposed and a fourth dielectric formed on the upper surface in the fourth region.

  • Patent number: 7347988
    Abstract: A method is disclosed for creating hydrogels with ordered crystalline structures that exhibit a characteristic colored opalescence. In addition to the unique optical properties, these materials contain a large amount of water in their crosslinked networks. The manufacturing processes include synthesizing monodispersed hydrogel nanoparticles containing specific reactive functional groups, self-assembly of these particles to form a crystalline structure, and subsequent crosslinking neighboring spheres to stabilize the entire network. Polymerizing a hydrogel monomeric composition around the crystalline structure can enhance the mechanical strength. The resulting network is dimensionally and thermodynamically stabile under various pH and temperature conditions. The color and volume of these crystalline hydrogel networks can reversibly change in response to external stimuli such as temperature, pH and other environmental conditions.
