  • Patent number: 7515043
    Abstract: A method for communicating data using at least one network linking at least one respondent device with at least one monitoring device, said method comprising the steps of: continuously measuring at least one physiologic parameter for purposes of detecting a predetermined event using said at least one monitoring device; operating said network in an off state in which said network is off except for the periodic transmission of patient status data while said network is in a first operative state wherein said predetermined event has not occurred and transmitting said measured data along said at least one said network in a second state when said predetermined event has occurred.

  • Patent number: 7515044
    Abstract: A method for performing context management, said method comprising the steps of: producing a continuous physiologic signal, as detected by a monitoring device; associating at least one unique hardware identifier to said continuous physiologic signal and binding a unique patient identifier to said continuous signal wherein a change in said physiologic signal in which said signal is no longer continuous will cause the unique patient identifier to unbind from said signal.

  • Patent number: 7382247
    Abstract: A system for actively monitoring a patient includes at least one body-worn monitoring device that has at least one sensor capable of measuring at least one physiologic parameter and detecting at least one predetermined event. At least one intermediary device is, linked to the body-worn monitoring device by means of a first wireless network and at least one respondent device is linked to said at least one intermediary device by a second wireless network wherein the respondent device is programmed to perform a specified function automatically when the at least one predetermined event is realized. The monitoring device operates to periodically transmit patient status data to the intermediary device but the system predominantly operates in a quiet state, providing very low power consumption.

  • Patent number: 6938025
    Abstract: A method and apparatus for automatically determining salient features for object classification is provided. In accordance with one embodiment, one or more unique features are extracted from a first content group of objects to form a first feature list, and one or more unique features are extracted from a second anti-content group of objects to form a second feature list. A ranked list of features is then created by applying statistical differentiation between unique features of the first feature list and unique features of the second feature list. A set of salient features is then identified from the resulting ranked list of features.

  • Patent number: 6826576
    Abstract: A method and apparatus for efficiently classifying and categorizing data objects such as electronic text, graphics, and audio based documents within very-large-scale hierarchical classification trees is provided. In accordance with one embodiment of the invention, a first node of a plurality of nodes of a subject hierarchy is selected. Previously classified data objects corresponding to a selected first node of a subject hierarchy as well as any associated sub-nodes of the selected node are aggregated to form a content class of data objects. Similarly, data objects corresponding to sibling nodes of the selected node and any associated sub-nodes of the sibling nodes are then aggregated to form an anti-content class of data objects. Features are then extracted from each of the content class of data objects and the anti-content class of data objects to facilitate characterization of said previously classified data objects.

  • Publication number: 20030225763
    Abstract: A self-improving system and method for classifying a plurality of digital documents such as web pages into one or more categories. Textual features and contextual features are extracted from a digital document and submitted to a committee machine. The committee machine assigns a rating to the digital document as a function of the extracted features and provides the location such as a URL for the digital document and its rating to an output data store. The output data store stores a list of locations for the plurality of digital documents. The output data store further segregates the locations of the digital document into categories based on the content of each document as indicated by the assigned rating.

  • Patent number: 5657398
    Abstract: A high-quality, low-bit-rate method of compressing physiological-waveform data obtained from a signal sent from a diagnostic medical device is disclosed. Associated with the signal are time and voltage characteristics. The method includes the steps of (1) examining such signal during a periodic event in which such data occurs, and which data includes a first region dominated by high-frequency information and a second region dominated by low-frequency information, and (2) removing the first region from the event based upon preselected criteria, which criteria are independent of indicia related to the first region. Also included is the step of compressing the data by processing the removed first region according to a first preselected plan which emphasizes low-bit-rate compression, and by processing the data of the entire event according to a second preselected plan which emphasizes high-quality compression.
