Appl. No.:

10/277438

Inventors:

Patti L. McCalmont - Oswego IL
Robert A. Sherry - Aurora IL
Ronald W. Mathis - Houston TX
Peter R. Schmidt - Westminster CO

Assignee:

Intrado Inc. - Longmont CO

International Classification:

H04M 1104

US Classification:

379 45, 379 37, 379 42

Abstract:

The present invention is related to the delivery of requests for emergency service initially handled by an emergency service call center to a public safety answering point. The invention additionally allows for enhancement information to be provided to a public safety answering point operator visually in connection with calls routed to that public safety answering point. This information may include caller identification, and additional information, such as information regarding the location of the caller and the nature of the emergency. Furthermore, the routing of requests for emergency service to an appropriate public safety answering point can be accomplished for requests received over a wide geographic area. In particular, requests can be appropriately routed even though they may originate from locations encompassed by different E9-1-1 tandems. The present invention is particularly well suited for use in connection with automatic collision notification and personal alarm monitoring call centers serving areas encompassed by more than one E9-1-1 tandem.

International Classification:

H03M001/12

US Classification:

341155, 341126

Abstract:

A waveform acquisition system that captures and digitizes a wideband electrical signal through a bank of front end filters, frequency down converters, and conventional digitizers (A/D converters). A software algorithm reconstructs the composite input signal and applies the necessary corrections to remove the effects of hardware impairments. This approach is possible because it uses a class of filters that exhibit the quality of perfect waveform reconstruction, allowing signals whose spectral components overlap multiple filter bands, to be faithfully reconstructed. A calibration generator switched into the input port serves as a reference for quantifying and removing hardware errors. The channelized analog-to-digital converter (ADC) effectively multiplies the bandwidth and sampling rate of the conventional digitizer performance in a single channel by the number of channels in the system.

Assignee:

General Dynamics Corp., Electronics Divn. - San Diego CA

International Classification:

G02B 2742
H01S 310

US Classification:

35016224

Abstract:

An optical modulator for generating an amplitude modulated optical signal. A signal generator generates an optical signal that is optically coupled to a tunable filter which shares a common optical axis with the signal generator. The tunable filter wavelength response varies in response to an electrical input control signal thereby providing an output amplitude modulated optical signal. An optical isolator is located between and shares a common optical axis with the signal generator and the tunable filter. The optical isolator is for preventing optical signals originating at the filter, traveling toward the signal generator, from impinging on the signal generator.

US Classification:

350 9616

Abstract:

A fiber optic data bus that includes a multiplexer means for generating a plurality of optical signals and for intensity modulating each of the optical signals in response to a respective one of a plurality of input RF signals each at a different RF carrier frequency to provide a plurality of intensity modulated optical signals. A signal collection means combines the plurality of intensity modulated optical signals into a combined optical signal. A conducting means conducts the combined optical signal to a signal distribution means which distributes the combined optical signal to each of a plurality of output ports. A demultiplexer means extracts from a portion of one of the distributed combined optical signals an output RF signal substantially identical to a predetermined one of the plurality of RF input signals.

International Classification:

G02B 626

US Classification:

350 9615

Abstract:

A fiber optic power coupling device such as a power summer, power divider or star coupler comprises a segment of multimode optical fiber having an input mirror at one end and an output mirror at the opposite end. One or more inputs at the input end of the fiber segment direct an equivalent number of input, intensity modulated light signals into the fiber and one or more outputs at the output end direct a corresponding number of output signals out of the fiber. Where there is one input and a plurality of outputs, the device acts as a power divider. Where there are a plurality of inputs and one output, the device acts as a power summer. Where there are a plurality of inputs and a plurality of outputs, the device acts as a star coupler.
