  • Patent number: 10548021
    Abstract: Various embodiments of systems, architecture, and/or methods are described for negotiating accesses to wireless spectrum of heterogeneous networks (e.g., Wifi, cellular 3G, cellular LTE, cellular 5G etc.) among multiple users, service providers, and services. As such, a software defined architecture is disclosed. In some embodiments, the disclosed software defined architecture can include establishing a (dedicated) logical control path from a central controller remotely located from an end device of a user. Such a logical control path is agnostic to the type and/or number of underlying wireless networks and is supplemental to conventionally known data paths, i.e., paths for exchanging data.

  • Patent number: 9292493
    Abstract: An apparatus and method for determining whether text is deceptive has a computer programmed with software that automatically analyzes text in digital form by at least one of statistical analysis of psycho-linguistic cues, IP geo-location, gender analysis, authorship analysis, and analysis to detect coded/camouflaged messages. The computer has truth data against which the text message can be compared and a graphical user interface. The computer may be connectable to the Internet and may obtain the text automatically. Speech-to-text software may be used to convert verbal messages to text for analysis. The system may be made available on a webpage, web service, on a computer or by a wireless device. The text may be emails, website content, tweets. In one embodiment, the system detects coded messages.

  • Publication number: 20150254566
    Abstract: A method and apparatus for automatically identifying harmful electronic messages, such as those presented in emails, on Craigslist or on Twitter, Facebook and other social media websites, features methodology for discriminating unwanted garbage communications (spam) and unwanted deceptive messages (scam) from wanted, truthful communications based upon patterns discernable from samples of each type of electronic communication. Methods are proposed that enable discrimination of wanted from unwanted communications in short electronic messages, such as on Twitter and for multilingual application.

  • Patent number: 9116877
    Abstract: An apparatus and method for determining whether a text is deceptive may comprise analyzing a body of textual content known to be one of text containing true content and text containing deceptive content; identifying psycho-linguistic cues that are indicative of a text being deceptive; statistically analyzing, via a computing device, a given text based upon the psycho-linguistic cues to determine if the text is deceptive. The apparatus and method may further comprise weighting the psycho-linguistic cues and statistically analyzing based on the weighted psycho-linguistic cues. The statistically analyzing step may be performed using one of a cue matching analysis, a weighted cue matching analysis, a Markov chain analysis, and a sequential probability ratio testing binary hypothesis analysis. The psycho-linguistic cues may be separated into categories, including increasing trend cues and decreasing trend cues and analyzed according to presence in a category from within the categories.

  • Patent number: 8873580
    Abstract: Apparatus and methods are disclosed for improving wireless and other network communications, e.g., through improving resource utilization, which may comprise the steps of accumulating channel modeling information relating to channel performance; calculating a channel parameter threshold based on the accumulated channel modeling information, whereby the channel parameter, as measured, being above the threshold indicates the channel is a good channel; adjusting traffic over a selected good channel to improve performance of the network or a network resource. The network resource may comprises battery life for devices operating on the network, data rate for devices operating on the network, constituting or reconstituting ad hoc networks comprising nodes separated by multiple hops, continuity of connectivity within a single communication link over the network, etc.
