  • Publication number: 20240070400
    Abstract: Method of analysis text message syntactically and by content, which entails: step 1; Split syntaxes (made available to subscribers by the network operator) into tokens to store in a Syntax Trie; step 2. Pre-process an incoming text from a subscriber; step 3. Split the text (pre-processed in Step 2) into tokens; step 4. Look up paths that include the tokens (obtained in Step 3) in the Syntax Trie (initialized in Step 1); step 5: Return the look-up result, which is the path in the Syntax Trie that best reflects the user intent.

  • Patent number: 8995908
    Abstract: A communications system may include a communications device including a first Bluetooth transceiver. The first Bluetooth transceiver may comprise a clock. The first Bluetooth transceiver may be capable of scanning a plurality of different operating frequencies for a pairing request based upon the clock. The communications device may further include an output device coupled with the Bluetooth transceiver and capable of outputting data associated with the clock via a communications path different than Bluetooth. The system may also include a mobile communications device including an input device capable of receiving the clock data from the output device via the communications path, and a second Bluetooth transceiver coupled with the input device and capable of generating the pairing request based upon the received clock data.
