Title: Holding party call back subscriber feature
Inventor: REICHELT MARTIN
IPC: H04M3/48
Filed: 1997-05-29
Abstract: A first subscriber (30a) activates a hold call back subscriber feature in response to a second subscriber (30b) placing the first subscriber on call hold. After the activation, the first subscriber goes onhook. When the second subscriber later wishes to take the first subscriber off of call hold, a first end office (20a) serving the first subscriber recognizes the second subscriber's action and accordingly alerts the first subscriber back. Upon answering the ring back, a call connection is re-established between the first subscriber and the second subscriber. A connection-less signal is communicated between the first end office and a second end office (20b) serving the second subscriber to queue, monitor, and inform the second subscriber's action. Upon receiving a connection-less signal from the second office indicating that the second subscriber wishes to take the first subscriber off of call hold, the first end office originates another call setup request towards the second subscriber.

Title: Optical fiber distribution module, optical fiber cord and fiber distribution system
Inventor: URUNO SHIGENORI
IPC: G02B6/44
Filed: 1999-07-21
Abstract: An optical fiber distribution module achieves high density of connections on one board, yet prevents fiber cord tangling created by repeated connection/disconnection of cords. The module has a connection board with an array of optical connector adaptors for connecting in-use optical fiber cords, and a storage section for storing not-in use optical fiber cords, where a plurality of cord sorting boards having a plurality of fiber cord passageways for accommodating and retaining at least one optical fiber cord is arranged between the connection board and the storage section. This design of the board enables to organize groups of cords into in-use cords and not-in-use cords. The load on the cords are supported properly so that fiber tangling and fiber distortion are prevented. Therefore, high density optical fiber can be achieved without introducing signal distortions.

A method for detecting a fluid leak in an isolated segment of a pipe: The method consists of five steps: Step 1, measure the average propagation velocity of the fluid in an isolated segment of the pipeline at time t1. Step 2, measure the pressure of the fluid in the isolated segment of the pipe at time t1. Step 3, measure the pressure of the fluid in the isolated segment of the pipe at time t2 and calculate the change in pressure occurring between t2 and t1. Step 4, measure the average propagation velocity of the fluid in an isolated segment of the pipe at time t2 and determine the corresponding change in average temperature. Step 5, calculate the amount of pressure change due to temperature changes and the amount due to probable leaks.
