Abstract: 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.

Abstract: Automatic Location Indication (ALI) data is digitally transferred from a Public Safety Answering Point (PSAP) to a first responder via a web site accessed by the first responder. The web site lists each live E911 call within their jurisdiction, and appends the caller's ALI and/or other location data relative to each call. Preferably the first responders (e.g., police car, paramedic, ambulance, fire truck, etc.) can view not only the emergency caller's information for those E911 calls that they are responding to, but also information about other emergency callers that other first responders are responding to. This facilitates the actual response to individual emergency calls as well as the overall management of multiple responders to multiple emergency calls.

Abstract: 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.

Abstract: An E-9-1-1 voice-over-IP (VoIP) solution is provided wherein a 911 call from a wireless 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. 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.

Abstract: The invention provides a current sensor that may be folded over a conductor without the need to sever the conductor or thread the conductor through the current sensor. In one embodiment, the current sensor includes an outer body having a first folding portion and a second folding portion coupled to the first folding portion. The current sensor also includes a soft ferromagnetic body disposed within the outer body comprising a first core element and a second core element. The first and second core elements form a lumen when the first and second folding portions are folded. The lumen is configured to receive a conductor. The current sensor also includes a magnetic field detector to sense a current in the conductor. The magnetic field detector is disposed at least partially between the first and second core elements when the first and second folding portions are folded.

Abstract: A voice over Internet Protocol (VoIP) positioning center (VPC) is implemented in configuration with support from a text-to-voice module, emergency routing database, and VoIP switching points (VSPs) to allow a public safety access point (PSAP) or other emergency center to effectively communicate the nature of an emergency alert notification and the area of notification to the VoIP positioning center (VPC). The inventive VPC in turn determines which phones (including wireless and/or VoIP phones) are currently in the area for notification, and reliably and quickly issues the required warning to all affected wireless and VoIP phones.

Abstract: A text messaging caller is enabled to communicate with a called party situated at on voice network, such as a PSTN or emergency 911 service center. The method comprises providing a service center, pre-registering a caller with the service center, receiving a text message from the caller through the service center, converting the text message to a voice message, ascertaining the address of the caller according to pre-registration information, and sending the voice message to the called party on the voice network together with the caller's identification and location information.

Abstract: An integrated circuit current sensor includes a lead frame having at least two leads coupled to provide a current conductor portion, and substrate having a first surface in which is disposed one or more magnetic field transducers, with the first surface being proximate the current conductor portion and a second surface distal from the current conductor portion. In one particular embodiment, the substrate is disposed having the first surface of the substrate above the current conductor portion and the second surface of the substrate above the first surface. In this particular embodiment, the substrate is oriented upside-down in the integrated circuit relative to a conventional orientation. With this arrangement, a current sensor is provided for which the one or more magnetic field transducers are very close to the current conductor portion, resulting in a current sensor having improved sensitivity.

Abstract: A switched emergency call (e.g., a 911 call, an alarm company call) forwarded by a telematics call center is converted into a session initiation protocol (SIP) packetized phone call at the call center, and routed over an IP network, for presentation to an emergency services gateway, which connects to a selective router via dedicated circuits, gaining full access to the Enhanced 911 network. This provides a PSAP receiving a call from a telematics call center or other call center with all features available in an Enhanced 911 network, e.g., callback number of the 911 caller, and location of the 911 caller. Location of the caller is provided using a VoIP positioning center (VPC), queried from the call center. In this way, the switched emergency call is converted into a SIP packetized phone call and routed without further passage through the public switched telephone network (PSTN).

Abstract: A reactor for carrying out a reaction between at least two fluids comprises a reactor plate (20) with a plurality of grooves or through slots (22) in which the fluids mix and react and a separable overlying reservoir plate (2) for supplying the fluids to slots (22) from reservoirs (4, 6) via slots (10) a, (10) b, with a collecting conduit or reservoir (8) and slots (10) c for the product of the reaction. Reservoir plate (2) may lie between two reactor plates, or a single reactor plate (20) may lie between two reservoir plates. Third or further reservoirs may or may not be spaced from the second reservoir (6) depending on whether more than two fluids need to be present simultaneously, or whether a second reaction is required after the first two fluids have had time to react. Means may be provided for controlling the pressure in slots (22), the pressure differential (and flow rate) along slot (22), and/or the temperature in the reservoirs (4, 6) or slots (22).
