Multi-line telephone system emergency call processing

A system for handling a call requiring non-standard processing to a call answer point and for providing location information concerning the call to the call answer point, comprising a call routing apparatus for identifying the call as requiring non-standard processing and in response providing a priority routing for the call, translation table apparatus for receiving the call via the priority routing and in response assigning a predetermined designation for indicating the location information, protocol harmonization apparatus for formatting the call for digital transmission to the call answer point, including inserting the predetermined designation in an information portion of the digital transmission, and digital interface apparatus for receiving the call properly formatted for the digital transmission and in response transmitting the call to the call answer point, whereupon the call answer point ascertains the location of origination of the call from the predetermined designation.

Apparatus and method for locating a station initiating transmission of an emergency message in a network having multiple transmission sources

A system for identifying the location of an individual at a transmission source who has initiated a message relating to an emergency. The system includes means for determining the specific location of the message initiator.

gravity gradiometer with twist pivots

Mooring failure detection

A mooring failure detector, for attachment to a mooring chain or wire rope, includes a power source, which is activated by the rupture of a rupture element, caused by a change in depth and hence pressure of the device. Activation of the power QC source provides power to a transmitter to signal the failure, either by acoustic or radio frequency means. The device can operate on an inclined mooring such that failure above or below the point of attachment results in a failure signal being transmitted.

Emergency call station identification system and method

ABSTRACT OF THE DISCLOSURE A method and apparatus is disclosed for harmonizing the protocol of a private branch exchange (PBX), servicing a plurality of stations, with the protocol of an enhanced "9-1-1-" emergency call network. The PBX is provided with a plurality of connections. A switching tandem of the emergency call network is also provided with a plurality of connections. A harmonization module is provided which has a first plurality of connections corresponding in type and number to the connections of the PBX. A second plurality of connections corresponds in type and number to the connections of the switching tandem. The connections of the PBX are interconnected with the corresponding first plurality of connections of the harmonization module using tie-line interconnections. The connections of the switching tandem are interconnected with the corresponding second plurality of connections of the harmonization module. A plurality of trunk interconnections is used for this purpose. A connection of the PBX is exercised in response to transmission of a signal indicative of initiating of an emergency call by one of the stations serviced by the PBX. The exercise of the PBX connection is sensed at the corresponding connection of the harmonization module. A trunk interconnecting a connection of the harmonization module and a corresponding connection of the switching tandem is seized. The switching tandem is caused to respond to the harmonization module. The response of the switching tandem at the harmonization module is sensed and the existence of the response condition relayed to the PBX. The invention secures the identification of the particular station and transmission of information to a public safety answering point so that the public safety answering point can call back to the station initiating the call and process information provided in order to specifically identify location of the station initiating the call.

The system has several arrays (10) of spaced-apart vibration-sensitive sensors (11), a hull (22) arranged adjacent to the noise sources (20), and a summing amplifier which receives the sensor output signals and forms the output signals which represent the average vibration signals from each array. The output of each summing amplifier is connected to a spectrum analyzer. A computer receives the noise spectrum of each array, provides the noise spectra with appropriate weighting factors, and combines rated noise spectra to form a prediction spectrum of radiated noise.

Valve test method and apparatus

The biasing spring of a valve is excited and the response detected to determine valve characteristics. Excitation is typically longitudinal oscillation applied by a vibrator connected in series with the spring. By performing a frequency sweep, resonance can be detected, and excitation can usefully be applied at the resonant frequency to produce valve lift. Testing can be performed in-situ, and maintenance of a plurality of valves is possible by collecting characteristic data for each valve and comparing against stored values.
