Abstract: An ultra wideband (UWB) jamming system comprises a processor, a memory, a pulse generator, one or more UWB transmitters, and one or more UWB antennas. In an exemplary embodiment of the present invention, the RF signals of a threat transmission or an RF-triggered explosive device (RTED) are evaluated and a set of interference parameters defined for the RF signal of that device. The interference parameters are predetermined to interfere with the reception or transmission of the RF signal. The interference parameters are sent to a pulse generator that drives one or more UWB transmitters to generate a signal has a statistically high probability of jamming or introducing an error in the threatening transmission.

Abstract: Sequential GPS Doppler carrier phase count measurements are used for precision sequential determination of position and velocity of a GPS receiver, such as for orbit determination and geolocation, with minimum throughput time. Real-time orbit determination and geolocation performance is enabled with an optimal sequential filter, and near-real-time performance is enabled with an optimal fixed-lag smoother. Many problems associated with prior art orbit determination are eliminated by addressing the “cycle slip” problem, the unknown initial range problem with RANGECP measurement representations, the problem of serial correlation in the measurements due to reprocessing of overlapping thermal noise. Also, the present invention significantly attenuates the carrier signal phase variation due to rotation of receiver antenna relative to transmitter antenna because the sequential phase count time intervals are sufficiently short.

Abstract: A system and method for observing patients in geographically dispersed health care locations. A portable monitoring station is associated with a patient assigned to a health care location. The portable monitoring station comprises monitoring equipment that monitors physiological measures of the patient. A remote command center receives the monitored data elements, accesses patient data elements indicative of a medical condition associated with the patient, and applies a patient-specific rule to selected data elements to determine whether the patient-specific rule has been contravened. The monitored equipment may further comprise video and audio equipment that captures patient video data and patient audio data and provides these data to the central command center.

Abstract: A three-wheeled stroller has a kickstand movable between a retracted position and a deployed position. When deployed, the kickstand has a pair of downwardly extending legs on either side of the front wheel to help prevent a tipping condition when an occupant enters or exits the stroller. Either a foot-operated actuator or a hand-operated actuator may be used to remotely operate the kickstand. In the case of a foot-operated actuator, stepping on a foot-operated brake bar can both operate the kickstand and immobilize one or more rear wheels to brake the stroller.

Abstract: A system for determining a treatment plan for a patient comprises a database of patient data elements indicative of a medical condition associated with a patient. A predictive model is applied to patient assessment data and used to prepare a treatment plan. A rules engine applies a patient rule consistent with the treatment plan to selected data elements stored in the database to produce an output indicative of a change in the medical condition of the patient. The output from the rules engine is used to determine if intervention is warranted. The predictive model is applied continuously to determine whether to update the treatment plan and, if necessary, the patient rule.

Abstract: A system and method for displaying a match alert. First and second user monitors are configured to communicate with an interrogator to establish the presence of the user monitors in a defined space. An information server is configured to determine whether profiles of the first and the second user profiles match according to matching criteria. If the first and the second user profiles match, matching alert signals comprising matching attributes are sent to first and second match indicators. The first match indicator is visible to the user of the second user monitor so as to be informative to the user of the second user monitor of the matching of the first and second user profiles according to the matching criteria, and the second match indicator is visible to the user of the first user monitor so as to be informative to the user of the first user monitor of the matching of the first and second user profiles according to the matching criteria.

Abstract: A system and method for displaying a security alert. First and second user monitors are configured to communicate with an interrogator to establish the presence of the user monitors in a defined space. An information server is configured to determine a degree to which the users of the first and second user monitors are permitted to exchange information according to security matching criteria applied to user profiles. Security alert signals are sent to first and second match indicators. The first match indicator is visible to the user of the second user monitor so as to be informative to the user of the second user monitor of a degree to which the users of the first and second user monitors are permitted to exchange information according to the security matching criteria.

Abstract: A system and method for providing premium transport in a DOCSIS-compliant cable network. An edge server in a DOCSIS-compliant cable network maintains a list of preferred content providers (PCPs). For each PCP, the PCP list comprises matching criteria. The edge server monitors the header of incoming packets for the matching criteria. A packet that matches the matching criteria is modified by the edge server causing the packet to be associated with a “premium” downstream service flow. Packets sent in response to a “preferred” packet are parsed by a cable modem and routed upstream according to a “premium” upstream service flow.

Abstract: A system and method for identifying and isolating faults in a video on demand (VOD) provisioning system. Transaction errors statistics are used to determine whether a fault has occurred in the VOD provisioning system. A high transaction error rate is associated with transaction error rates in components of the VOD provisioning system permitting identification of a likely cause of a high transaction error rate. Remedial action to repair the cause of the system fault is then directed to the likely cause of the high transaction error rate.

Abstract: Maximum conjunction probability calculations are refined by addressing rectangular object shapes, even though their orientation may not be known. Object dimensions and relative miss distance, coupled with the aspect ratio of the projected combined covariance, are used to determine the size and orientation of the covariance as well as the object orientation that produces the maximum probability. In treating the objects as rectangles instead of spheres, the probability calculation becomes more realistic by accounting for object shape. In the absence of object attitude information, a footprint is created that completely defines the region where the two objects might touch. This footprint can then be rotated to determine the orientation that produces the largest probability, making it the most conservative estimate for the given conjunction conditions.

Abstract: A system and method for managing provisioning parameters in a cable network. A dynamic TFTP (DTFTP) server and a CMTS manage the provisioning of devices in a cable network. The DTFTP server and the CMTS share common provisioning parameters. A provisioning parameter has a name and a value. When changes are made in the value of a provisioning parameter that is also used by a CMTSs supported by that DTFTP server, the DTFTP server securely communicates the new provisioning parameter values to each such CMTS. In one embodiment of the present invention, the DTFTP server pushes the new provisioning parameter values to the CMTSs. In another embodiment of the present invention, a poller pulls the provisioning parameters from the DTFTP server to a central datastore where changes in provisioning parameters used by the CMTSs supported by the DTFTP are identified. The changed provisioning parameter values are pushed from the central datastore to the CMTSs.

Abstract: A system and method for issuing an alarm when the separation distance between a monitoring module associated with an object (animate or inanimate) and an alert module exceeds a preset threshold distance thereby forming a leadless electronic tether between the object and the object owner. A monitoring module comprises a portable transmitter provides a signal to an alert module comprising a receiver and a processor. The alert module is adapted to determine a separation distance between the monitoring module and the alert module based on an attribute of the signal. When the separation distance exceeds a predetermined threshold, the alert module issues an alert. Alternatively, when the monitoring module signal is not received by the alert module, an alert is issued.

Abstract: Methods and systems for thwarting denial of service attacks originating in a DOCSIS-compliant cable network (DCN) are described. A DCN comprises one or more sub-networks each comprising an access network, one or more cable modem termination systems (CMTSs) and one or more cable modems (CMs). The DCN also accesses an edge server and a local DNS cache server. The DCN interfaces with the Internet and accesses a remote DNS server according to well-known protocols. The CMTS is adapted to compare the source IP address included in IP packet headers to the IP address of the customer premises equipment (CPE) from which the IP packet originates as assigned by the DNS. Data packets that have spoofed addresses are either deleted or quarantined. Packets reaching the edge server are evaluated by an attack detection system. A packet determined to be part of a denial of service attack is inspected and the source IP address and the destination IP address extracted.

Abstract: A fault isolation system and method. A hierarchical numbering system is applied to devices within a cable network. Each subscriber is associated with a “last active device” or “LAD” providing service to that subscriber. The numbering system provides “genealogical” information about the subscriber's LAD so that the LAD can be located within the network. By correlating trouble reports from subscribers, a fault in an active device can be isolated to a particular segment of a cascade if not a particular active device. The number system comprises a continuously concatenated string that provides a relative location of each active device with a cable network.

Abstract: Electronic discovery on computer systems and archives is provided by using statement analysis of to identify false statements so as to retrieve relevant impeachment data and other evidence related to recorded statements. The recorded statement is analyzed for possible false statements and corresponding transcript data of the false statement, any precipitating question, and any follow-up questions are selected for use in the query. The selected text can be further processed before being used in the query. The query can be used in a search engine or used to train smart search agents. The search engine query or smart search agents are released onto target computer systems and/or archives to search for responsive data and documents. Notification, reports, and indexing of responsive data and documents can be provided to produce relevant results. The analysis of the recorded statement is preferably done by voice stress analysis.

Abstract: A system and method for managing e-mail traffic originating from a specific IP address. An outbound e-mail message is routed to an e-mail governor where the IP address of the computer from which outbound e-mail message originated is determined. A record associated with the originating IP address is created in a datatstore. Metrics useful to determine an e-mail message rate and an e-mail byte rate are stored in the e-mail record. An e-mail message rate is determined and compared with an e-mail message rate threshold. If the e-mail message rate threshold is exceeded, the originating IP address is sending spam e-mail (spam) and redial action is taken. An e-mail byte rate is also determined and compared with an e-mail byte rate threshold. If the e-mail byte rate threshold is exceeded, the originating IP address is using excess network resources to send e-mail and redial action is taken.

Abstract: The present invention is drawn to a method and apparatus for taking advantage of the always-on nature of a broadband VoIP network connection to provide enhanced services triggered by the off-hook event, bypassing a dial tone. In use, a caller triggers a network based greeting upon the off-hook event of picking up the phone. The greeting can be used for unique branding purposes by speaking a greeting to the caller. After the greeting, the caller can be immediately connected to an array of network-based services. A voice recognition system is employed to permit the caller to use voice dialing. A network interactive voice response unit (VRU) is used with the voice recognition system to allow the user to access services from a menu. The VRU can respond to an affirmative statement from the caller by using a table to lookup the phone number of requested services closest to the caller based on the caller's phone number (i.e., ANI).

Abstract: A point of sale system designed to read information from a consumer's check, credit card, or manual input with a subsequent debiting of a consumer's account and crediting merchant's account for the goods or services provided. Point of sale terminals are designed to accept a form of credit card with a consumer's bank account information encoded thereon or in the alternative to read the MICR number from a consumer's check in order to verify that a consumer has an appropriate balance to conduct the transaction with a given merchant. Thereafter the transaction of that information is transmitted to a central computer system which verifies the consumer's credit worthiness and stores the transaction event information for subsequent bank reconciliation via the ACH or other competing network. The invention eliminates the need for paper checks with all bank reconciliation being accomplished electronically.
