Title: Method and apparatus for monitoring selected telecommunications sessions in an intelligent switched telephone network
Inventor: JONES ROBERT S
IPC: H04Q3/00
Filed: 1997-06-27
Granted: 2000-07-25
Abstract: A method,  system and  apparatus  for  the  transparent monitoring of  selected telecommunications  sessions  in  an intelligent switched telephone network is described.   The method  involves  conditioning  the  network  to  enable  the monitoring of all  telecommunications  sessions  originating from or terminating to any selected subscriber address.  The network  is  conditioned by the  installation  of monitored trunks with translation tables, linksets and routesets which route all calls to be monitored through the monitored trunk groups.    After  the  network  has  been  conditioned,  call monitoring can be accomplished with minimal datafill changes to the translation tables of the telephone switching system that serves the subscriber address.   The monitored trunk groups are preferably loop-back trunk groups, but they may be dedicated inter-office trunk groups as well.  It is also possible to designate a central switching point to monitor calls for a plurality of satellite switching points.   The advantage  is  a  flexible,  cost-effective  call  monitoring system that produces no echo, ping or noise on the monitored line.  The calls are completed without perceptible delay and there is no known method or equipment  for detecting the monitoring equipment from either end of the call connection.

Abstract: Two light signals (L1',L2') pass, in opposite directions, through a series circuit comprising a first optical fiber (4), a first polarizer (5), a Faraday sensor device (3), a second polarizer (6) and a second optical fiber (7). To set the working point, additionally, the planes of polarization of both light signals are reciprocally rotated by a predetermined angle of rotation by rotation means (8) between the two polari- zers. From light intensities (I1, I2) of the two light signals (L1,L2), after passing through the series cir- cuit, a measuring signal (M) is determined which is independent of vibrations and bending influences in the optical fibers.

Title: Feedback control system for telecommunications systems
Inventor: WEAVER CARL FRANCIS
IPC: H04B17/00
Filed: 1998-05-19
Granted: 2002-12-10
Abstract: Telecommunications processing is applied to a reference signal to generate a signal under test. A fidelity measure is generated characterizing the fidelity of the signal under test relative to the reference signal. A control signal is generated from the fidelity measure, where the control signal is used as a feedback signal to adjust the telecommunications processing. In one embodiment, the reference signal is a speech signal and the signal under test is a decoded speech signal generated by encoding, transmitting, and decoding the reference speech signal. The fidelity signal is an average mean opinion score (MOS) and the control signal is used to control the speech decoding processing. For example, the speech decoding processing may involve a speech decoder followed by a post filter, and the control signal is the cut-off frequency of the post filter. Such an embodiment may be applied to real-time speech processing to adjust the speech decoding processing in the receiver of a telecommunications system that includes a speech encoder in a transmitter and a communications network. Intermittently, the transmitter encodes reference signals that are also known to the receiver. The receiver performs the processing of the present invention to update its speech decoding processing to optimize speech quality.

Title: Portable/potable water recovery and dispensing apparatus
Inventor: FORSBERG FRANCIS C
IPC: C02F9/00
Filed: 1997-04-05
Granted: 2003-05-20
Abstract: A portable, potable water generator for producing high-purity liquid water by condensation of dew from ambient air is described.  The generator employs filtration subsystems (38) to remove particulates and aerosols from the incoming air. An enclosed heat absorber (22) cools the filtered air below its dew point and collects (25) droplets of condensate into a closed system (26). The collected liquid dew is further continually treated in a bacteriostat loop (29, 31) to destroy adventitious living organisms and to filter out undesirable and dangerous contaminants. All the subsystems are failsafe-interlocked to disable the generator immediately and prevent delivery of water if any one of them stops functioning within predetermined safe limits.  Hybrid embodiments of the water generator attached to or integrated with refrigeration-type appliances such as water coolers, refrigerators, freezers, icemakers and air-conditioners are illustrated.

Granted: 2003-07-22
Abstract: Blow-off nozzles are used for creating a high-energy air blast, for drying metal panels prior to painting. Depth or reach of penetration (in the atmosphere) is important. A  bullet is provided in the centre of the nozzle. The bullet is aerodynamically faired, for minimum drag. The effect of the bullet is to create a low pressure area in the jet downstream of the nozzle. The low pressure area serves to hold the jet together, preventing spreading, to a degree that enables a significant increase in penetration distance. The bullet is mounted on faired arms, which are secured to the walls of the nozzle.

Abstract: A cross-connect (92) for a multi-ring, multi-channel telecommunications network, especially for a wavelength-division multiplexed (WDM) optical network. Each of the interconnected rings (94 and (100) is self-healing by provision of a redundant counter-rotating ring (96 and 98)) or excess capaci ty on pairs of counter-rotating rings. Because an interconnect between self- healing rings (90) does not need to connect working to protection fibers, or  similarly redundant fibers, the complexity of the interconnect can be substantially reduced. For several important architectures, the interconnect  can be decomposed into one or two 3x3 interconnects. Further, a wide-sense n on- blocking 3x3 interconnect can be advantageously implemented as four 2x2 switches, which may be a basic building block of optical switches. A novel algorithm is available to add new paths through such a 3x3 interconnect. The  interconnect can be decomposed into one or two 4x4 interconnects when anothe r pair of add (102)/drop (104) lines are added. Such an architecture provides full connectivity between user nodes connected to the add (102)/drop (104) lines and user nodes attached to the rings.
