  • Patent number: 6912580
    Abstract: A computer has one or more communication interfaces that determine if one or more client (client devices) is within a range of communication of the computer. The computer also has one or more computer interfaces capable of communicating with one or more of the second computers. The second computers can be at any general location and/or installed as subsystems of other devices. An application process determines from the client signal that the client is within the range of communication and that requests and receives one or more of the application programs through the computer interface from one or more of the second computers at the commuter location. Thus, the application program (and necessary databases) are moved to a next computer as the client moves within the range of communication of this next computer. The application programs/databases can be discarded once the client moves outside of the range of communication of the computer.

  • Patent number: 6418423
    Abstract: Disclosed is a system and a method for combining the computational resources of numerous embedded devices to enable any of them to perform complex tasks like speech recognition or natural language understanding. A distinguished master device communicates with a network of embedded devices, and organizes them as the nodes of a neural network. To each node (embedded device) in the neural network, the master device sends the activation function for that node and the connectivity pattern for that node. The master device sends the inputs for the network to the distinguished input nodes of the network. During computation, each node computes the activation function of all of its inputs and sends its activation to all the nodes to which it needs to send output to. The outputs of the neural network are sent to the master device. Thus, the network of embedded devices can perform any computation (like speech recognition, natural language understanding, etc.) which can be mapped onto a neural network model.

  • Patent number: 6393470
    Abstract: A non intrusive method for freeing storage of portable devices (such as digital video cameras) when the portable device becomes full. This task is accomplished using a network of servers that communicate via wireless channels with the portable devices (like cameras) within the zones of these servers. That is, if a server detects that a camera (or other device) is near full with stored captured images (data), or meets some other criteria, this server moves stored images (data) to a storage server without interrupting possible owner actions with the camera/device. The owner can download all moved images/data from a storage server to his/her computer after returning to a home/office/hotel. Similar non intrusive services can be provided for other miniature devices with embedded storage that are using by owners during some their activities (like palmtops, tapes, smart phones, wrist watches etc.).

  • Publication number: 20010044906
    Abstract: To improve authenticity of persons accessing secured locations, information, services, and/or goods, random pictures (images) and/or portions of picture are placed on a document (hard copy—e.g. a check—or computer generated). The person requiring access selects a set of one or more of the images/pictures, e.g. by crossing them out. Often the selected images/picture with be familiar to the user. The document is screened, e.g. by a special access server over a network, to check on whether the subset was correct, i.e., matches a subset of images previously stored and associated with the accessor. This can be combined with printed explicit textual questions related to an owner personal database and several possible answers for each question. For further security, biometrics, e.g. from user handwritten answer prompts, can be added. Similar security provision with random visual images can be used when users interact with computers to get access to some services (without providing hard copy documents).

  • Patent number: 6236968
    Abstract: An automatic dialog system capable of keeping a drive awake while driving during a long trip or one that extends into the late evening. The system carries on a conversation with the driver on various topics utilizing a natural dialog car system. The system includes an automatic speech recognition module, a speech generation module which includes speech synthesis or recorded speech, and possibly dynamically combined speech synthesizer and recorded speech, and a natural language processing module. The natural dialog car system analyzes a driver's answer and the contents of the answer together with his voice patterns to determine if he is alert while driving. The system warns the driver or changes the topic of conversation if the system determines that the driver is about to fall asleep. The system may also detect whether a driver is effected by alcohol or drugs.

  • Patent number: 6009392
    Abstract: A method is provided which trains acoustic models in an automatic speech recognizer ("ASR") without explicitly matching decoded scripts with correct scripts from which acoustic training data is generated. In the method, audio data is input and segmented to produce audio segments. The audio segments are clustered into groups of clustered audio segments such that the clustered audio segments in each of the groups have similar characteristics. Also, the groups respectively form audio similarity classes. Then, audio segment probability distributions for the clustered audio segments in the audio similarity classes are calculated, and audio segment frequencies for the clustered audio segments are determined based on the audio segment probability distributions. The audio segment frequencies are matched to known audio segment frequencies for at least one of letters, combination of letters, and words to determine frequency matches, and a textual corpus of words is formed based on the frequency matches.

  • Patent number: 5937385
    Abstract: An automated system generates and revises grammars for speech recognizers in a speech recognition system. Given an initial grammar, expressed in terms of non-terminals in Backus-Naur Form (BNF) notation, a sentence generator generates a list of all sentences accepted by the grammar. From this list, a corpus of inappropriate or irrelevant sentences which are accepted by the grammar (counter-examples) is identified. A grammar revisor program uses the original grammar and the list of counter examples, to generate a pruned list from which a revised grammar is generated. The revision process is iterated several times either concatenating or merging pairs of non-terminals until the revised grammar is deemed satisfactory in that it accepts as legal only relevant sentences. The revised grammar is used by the speech recognizer, thus reducing errors in the overall system.

  • Patent number: 5774525
    Abstract: A method and corresponding apparatus utilizes questioning to provide secure access control including the steps of storing information in a database; generating at least one question based upon the information stored in the data base; communicating to the user the generated question(s); receiving a response associated with the question(s), interpreting the response to determine whether the response conforms to the information upon which is based the associated question(s); and outputting an authorization status indicating whether or not the user is authorized for access according to the determination. The question(s) concerns a relationship among portions of information contained in said data base. This feature is advantageous because it protects against an eavesdropper gaining access to the service or facility and provides the capability of generating a relatively large number of different questions from a small data base.

  • Patent number: 5649060
    Abstract: A method of automatically aligning a written transcript with speech in video and audio clips. The disclosed technique involves as a basic component an automatic speech recognizer. The automatic speech recognizer decodes speech (recorded on a tape) and produces a file with a decoded text. This decoded text is then matched with the original written transcript via identification of similar words or clusters of words. The results of this matching is an alignment of the speech with the original transcript. The method can be used (a) to create indexing of video clips, (b) for "teleprompting" (i.e. showing the next portion of text when someone is reading from a television screen), or (c) to enhance editing of a text that was dictated to a stenographer or recorded on a tape for its subsequent textual reproduction by a typist.
