摘要:
An E-9-1-1 voice-over-IP (VoIP) solution is provided wherein a 911 call from a mobile VoIP device is routed directly to the correct Public Safety Answer Point (PSAP) via dedicated trunks, together with correct location information and call-back number. VoIP gateways are implemented locally, at least one per LATA, and accept VoIP packetized data inbound, and convert it to standard wireline voice calls. Calls are routed to an IP address at the VoIP gateway, which then egresses the call to a voice port at a selective router. Mid-call updating of location of a moving VoIP terminal is provided to a PSAP. The location of the VoIP is validated using HTTP based protocol by pushing location information to a VoIP location server, and comparing it against a geographic location database to confirm that a contained street address is valid.

An accurate building-specific location for a mobile device requesting Enhanced 911 (E911) emergency services is provided while located indoors. A central server and associated plurality of emergency 911 wireless call detectors are programmed with Master Street Address Guide (MSAG) information, and installed throughout the walls of a given building to provide comprehensive E911 coverage. The building-specific information includes room number, floor number, column number, and/or other building information regarding the relevant detector's location in a corresponding building, and thus an accurate position of the calling mobile device within a given building.

Calls are routed to an IP address at the VoIP gateway, which then egresses the call to a voice port at a selective router. Dedicated voice trunks (CAMA, SS7, FG-D) are installed between each local VoIP gateway and appropriate selective routers. An Automatic Location Identification (ALI) database is provisioned with ESRKs dedicated for VoIP use. TCP/IP circuits may be established between some or all of the various local VoIP gateways.

Calls from a phone identified as being a source of harassing or other undesirable phone calls are blocked at a mobile positioning center (MPC). Upon request by the PSAP, a call record detail can be obtained from the MPC revealing a simulated “callback phone number” as well as a unique number identifier of the phone, such as an ESN or MEID. The MPC then intercepts all future incoming calls from phones with that unique identifier number and routes them to a recording that advises the harasser that the phone has been identified as a harasser and is now blocked. The recording can also advise the caller how to restore service. In a preferred embodiment, the MPC sets a timer to automatically restore service after a designated length of time.
摘要:
An electronic circuit includes a first substrate having a first substrate surface and a device supported by the first substrate surface. The device is selected from among a passive electronic component and an active electronic component. The electronic circuit also includes a second substrate having a second substrate surface and a conductor proximate to the second substrate. The electronic circuit also includes a magnetic field transducer disposed over the conductor and coupled to the device and an insulating layer disposed between the conductor and the second substrate. The conductor is adapted to carry an electrical current to generate a first magnetic field. The electronic circuit is responsive to the first magnetic field. In some embodiments, the conductor is a secondary conductor and the circuit further includes a primary conductor disposed proximate to the magnetic field transducer and an insulating layer disposed between the primary conductor and the second substrate.

An integrated sensor includes a magnetoresistance element electrically coupled to a device disposed on or integrated in a silicon substrate. A conductor is provided proximate to the magnetoresistance element. The integrated sensor can be used to provide various devices, such as a current sensor, a magnetic field sensor, or an isolator. Further, the integrated sensor can be used in an open loop configuration or in a closed loop configuration in which an additional conductor is provided. The magntoresistance element may be formed over the silicon substrate or on a separate, non-silicon substrate. Also described is an integrated sensor comprising a substrate, a magnetic field transducer disposed over a surface of the substrate, and a conductor disposed over the surface of the substrate proximate to the magnetic field transducer. The magnetic field transducer can be a Hall effect transducer or a magnetoresistance element.

A really simple syndication (RSS) feed generator provides a user access to a set of data in the form of an RSS feed containing an object. The RSS feed generator allows the user to generate a feed definition using any of a user interface, a web based application programming interface, and an HTTP request. The RSS feed generator uses the feed definition provided by the user to generate the RSS feed and exposes the RSS feed in the form of RSS XML data. The RSS feed generator allows a business system to dynamically update the set of data contained in the RSS feed in a manner that allows a user to perform a plurality of functions on the RSS feed.

A method and system for the graphical formulation of filter queries is disclosed which enables data queries to be easily via selection from a menu. A signal is received to filter, or query, a data table. Next, the context of the signaled key field is analyzed, and a menu of filters based on that context is formulated and displayed. A filter selection is received, and the corresponding filter is executed. The results of the filter are displayed on the screen.
