Abstract:
A body worn patient monitoring device includes at least one disposable module including a plurality of electrical connections to the body. The body worn patient monitoring device also includes at least one communication-computation module, the communication-computation module having at least one microprocessor to actively monitor the patient and to perform a real-time physiological analysis of the physiological signals. A radio circuit communicates a raw physiological signal or a result of the physiological analysis at a predetermined time or on the occurrence of a predetermined event, via a radio transmission to a remote radio receiver, wherein the at least one disposable module is mechanically and electrically coupled directly to the at least one communication-computation module. The body worn patient monitoring device, including the at least one disposable module and the at least one communication-computation module, is directly non-permanently affixed to the skin surface of the patient.
Abstract:
Disclosed in this specification is a method for monitoring a network, such as the central monitoring station of a medical facility. Performance data from each of the network components of interest is monitored for compliance with certain component-specific criteria. Responses are generated if the performance data satisfies, or fails to satisfy, such criteria.
Abstract:
One embodiment of the present invention provides a system that automatically generates synonyms for words from documents. During operation, this system determines co-occurrence frequencies for pairs of words in the documents. The system also determines closeness scores for pairs of words in the documents, wherein a closeness score indicates whether a pair of words are located so close to each other that the words are likely to occur in the same sentence or phrase. Finally, the system determines whether pairs of words are synonyms based on the determined co-occurrence frequencies and the determined closeness scores. While making this determination, the system can additionally consider correlations between words in a title or an anchor of a document and words in the document as well as word-form scores for pairs of words in the documents.
Abstract:
One embodiment of the present invention provides a system for detecting correlations between terms. During operation, the system identifies one or more lists contained in one or more documents and identifies two terms co-occurring in the lists. The system further determines a correlation between the co-occurring terms, and places the co-occurring terms in a correlated-pair list based on the correlation.
Abstract:
The invention relates generally to a method to ensure that mission-critical data is transported safely and effectively across a wireless LAN, and more particularly, to a method which determines network latency under model network loads and ensures that the RF signal strength requirements are met for all RF coverage areas supported by the wireless network, allowing for data transmission which is effective and complete, with acceptable latency and loss, and no unacceptable corruption of the data.
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.
Abstract:
An apparatus and method contemplate the use of a downhole tool, at least one magnet, and a magnetic energy converter for generating electricity in a receiver positioned in a subsurface formation. The downhole tool is connected to a drilling or a logging assembly disposed in a wellbore. The magnet, which is attached to the downhole tool, generates a magnetic field extending into the formation. The magnetic energy converter, which is contained in the receiver located in the formation, is exposed to variations of the flux of the magnetic field generated by the magnet. These magnetic flux variations through the magnetic energy converter generate electricity in the receiver. The invention may be expressed in various embodiments that contemplate the use of pluralities of magnets arranged in different configurations.
