Abstract: Natural language interface to a back-end application, incorporating synonyms, suggestions, and proposals. Roughly described, synonyms are automatically added to user input to enhance the natural language interpretation, whereas suggestions and proposals are offered to the user in an interaction, usually after an interpretation of prior user input. Suggestions and synonyms can be learned from user input, whereas proposals are programmed by a third party. The selection of synonyms, suggestions, and proposals for use with particular user input can be user input context-based so that further user input can maintain context by explicitly indicating that the same context is intended, and rewards-based reinforcement can be used to better focus suggestions and proposals on the characteristics of the particular user.
Abstract: System and methods for providing multimedia message service (MMS) interoperability between an initiating carrier and a destination carrier.

Abstract: A filter according to a present invention embodiment reduces the effects of microphonic behavior in a communications network. The filter passes a network signal, while filtering out unwanted voiceband leakage (e.g., emissions of plaintext voice signals) due to microphonic behavior of the network equipment. The filter employs inductive units each including at least two inductive elements connected in series and arranged to cancel current within the inductive elements induced by vibrations and/or sound pressure (or acoustic) waves in the surrounding environment, thereby reducing extraneous signals produced within the filter (e.g., signals produced from microphonic behavior that may be in the form of perceivable voice or audio, noise, etc.). The filter reduces the extraneous signals in active and passive modes, and prevents compromise of secure or sensitive information (e.g., in the form of perceivable voice or audio) due to microphonic behavior of filter elements.
Abstract: A trellis processing technique for estimating a transmitted signal from a received signal acquired through a channel achieves a reduced computational structure when implementing a DDFSE-like branch metrics calculation by pre-storing computed values, which can be re-used. The technique involves storing differences between a received symbol and different products, each of which is a product of a channel coefficient corresponding to a least time delay and a different possible transmitted symbol. A summation of products is calculated, each product being a product of a possible transmitted signal symbol and a channel coefficient other than the channel coefficient corresponding to the least time delay, the summation being specific to a branch-start state in a trellis. The summation is combined with different stored differences in a calculation of branch metrics leading to different branch-end states in the trellis.

Abstract: In one embodiment, a processing device is coupled between at least one content source and at least one subscriber device within an Internet Protocol television (IPTV) system in order to receive a plurality of service flows from the at least one content source and to process multicast service flow requests from the at least one subscriber device. The processing device includes a map module to map a service flow from a content source to a multicast service flow based on a multicast service flow request from a particular subscriber device and a unicast module to assign a unique identifier to the mapped multicast service flow to convert the mapped multicast service flow to a unicast delivery of the mapped multicast service flow to the particular subscriber device.
Abstract: A method and apparatus for forming nonwoven melt spun webs by spinning a curtain of filaments into a pressurized chamber where they are contacted with pressurized quenching fluid, then using the fluid to draw the filaments through a slot at the bottom of the chamber. The slot is a narrow two dimensional impingement point running the length of the filament curtain where the pressurized quench fluid passes through, escaping to atmosphere. The fluid pressure (potential) energy in the chamber is exchanged for velocity (kinetic) energy at the slot impingement point. The fast moving stream of fluid inside and exiting the slot acts to pull, or draw the filaments through the slot. The fluid and fiber stream is deposited onto a porous collection conveyor belt, forming a fleece web. The invention is more efficient, less complicated, easier to maintain and easier to control than prior systems for melt spinning nonwoven webs.
Abstract: Systems and methods for assigning a short codes to provide uniformity among wireless carriers. In the systems and methods, a Universal Short Code (USC) Administrator maintains a list of short codes and their lease status so that SMS messages sent to a particular short code may be routed to the proper holder of the short code. A network facilitator is in communication with both the USC Administrator and at least one wireless carrier to route the SMS message to the proper holder of the short code. The short code may be leased for a specified period of time so that the short code can be reassigned after expiration of the lease.

Abstract: An algorithm is provided that computes values for correcting for DC offsets of baseband I and Q signals, compensates for amplitude imbalance between the baseband I and Q signals and compensates for phase imbalance between the baseband I and Q signals. Test signals are injected into the I and Q signal processing paths (either or both of the receiver path and baseband path in a modem). Samples of the I and Q signals produced in the I and Q signal processing paths are generated and analyzed to determine DC offsets of the I and Q signals, amplitude imbalance between the I and Q signals and phase imbalance with respect to a desired orthogonal relationship between the I and Q signals.
Abstract: A method and apparatus for synchronizing time of day (TOD) information between radio nodes of a network and for detecting and merging otherwise isolated radio networks. In this manner individual isolated networks are able start when they are ready and once connectivity is detected with another network, the two networks can merge. Radio nodes within each network periodically send out TOD messages and periodically receive TOD messages issued by other nodes look to identify networks within communication range. Upon detecting another network a radio node informs a central control node that uses network detection information received from its members to determine the extent of the connectivity between the two networks and whether to merge the two networks. Network searching is optimized to limit impact on the overall network performance, resulting in little or no degradation in network performance.
