20090152267 | Container Assembly - A container assembly has a first container that operably houses a second container. The first container is configured to hold a first flowable substance, and the second container is configured to hold a second flowable substance. The second container is rupturable, preferably by manipulation through the first container, wherein the second flowable substance can mix with the first flowable substance to form a mixture. The first container is also rupturable to dispense the mixture therefrom. | 06-18-2009 |

20120093510 | CORRELATION -CONTROL QPSK TRANSMITTER - An optical transmitter utilizing a multi-level data modulator to produce a PDM-QPSK signal, a one-bit delay interferometer configured to correlate the multi-level data modulated signal and an optical filter configured to combine the correlated multi-level data modulated signal with one or more neighboring signals prior to transmitting over one of a plurality of optical channels. The PDM-QPSK correlated signal is configured to reduce the signal spectrum thereby increasing spectral efficiency of the transmitted signal. | 04-19-2012 |

20090028552 | System and Method for Wavelength Monitoring and Control - A system and method using for wavelength monitoring and control in a WDM optical communication system. An aggregate channel monitor detects crosstalk between channels in the aggregate signal. Channel spacing may be modified by an element management system in response to the output of the aggregate channel monitor. | 01-29-2009 |
20100034537 | FREQUENCY OFFSET POLARIZATION MULTIPLEXING MODULATION FORMAT AND SYSTEM INCORPORATING THE SAME - An apparatus, system and method wherein a polarization multiplexed differential phase shift keying format (POLMUX-DPSK) is provided with offset and bit-interleaved frequency channels and demodulated using a DPSK demodulator. | 02-11-2010 |
20120213521 | VESTIGIAL PHASE SHIFT KEYING MODULATION AND SYSTEMS AND METHODS INCORPORATING SAME - In general, optical communication systems and methods may implement a vestigial phase shift keying (PSK) modulation format to enable relatively high transmission rates with closer channel spacing and improved signal detection in a WDM optical communication system. A PSK modulated signal may be correlated with a phase shift, for example, using a delay line interferometer (DLI), to generate a vestigial PSK signal, which may be pre-filtered, combined, and transmitted in the WDM system. The correlation with a phase shift compresses and shifts the signal spectrum such that intersymbol interference (ISI) length may be reduced with minimal increase in the bit error rate (BER) when the vestigial PSK signal is detected. | 08-23-2012 |
20120213522 | GENERATING HIGHER-LEVEL QUADRATURE AMPLITUDE MODULATION (QAM) USING A DELAY LINE INTERFEROMETER AND SYSTEMS AND METHODS INCORPORATING SAME - In general, optical communication systems and methods may generate higher-level n | 08-23-2012 |

20130250751 | ACCELERATED RECOVERY DURING NEGOTIATION BETWEEN A MEDIA GATEWAY AND A MEDIA GATEWAY CONTROLLER - A method is disclosed that enables an improved technique for recovering from an error scenario encountered during a call setup involving a malfunctioning media gateway and corresponding media gateway controller. The media gateway first detects a malfunction that affects a digital signal processing resource, and then proactively selects a processing resource available elsewhere at the gateway. The media gateway selects the new processing resource based on criteria including: i) the capabilities that were identified to handle the packet stream at the affected (faulty) processor; ii) the capabilities of the IP terminal originating the packet stream that is being moved; and iii) the Internet Protocol address of the affected processing resource. Advantageously, an effort is made to avoid having to inform the media gateway controller of the move, thereby minimizing any discontinuity in each packet stream and minimizing the time and processing that are required to establish the call. | 09-26-2013 |

20100027528 | Notification of Impending Media Gateway Resource Exhaustion - A method is disclosed that enables a media gateway controller to optimize the selection of a media gateway from which to acquire call-related resources, in a multi-gateway environment. In accordance with the illustrative embodiment, the controller sets a high utilization threshold and a low utilization threshold for each media gateway it controls, for the purpose of receiving a notification when a threshold is crossed. As resources are utilized, removed from service, or become available for use, the media gateway recalculates the resource utilization of one or more predetermined resources and notifies the controller if a threshold for a particular resource has been crossed. The controller, in turn, uses the current threshold states as part of the selection of media gateway to serve one or more subsequent calls. The disclosed method can increase the probability of selecting a media gateway with sufficient resources for a successful call completion on the first attempt. | 02-04-2010 |

20080202997 | Debris bag for a swimming pool cleaning apparatus - A debris bag for a swimming pool cleaning device includes a body having a debris collection cavity, an upper end and a lower end. The lower end engages the pool cleaner to receive debris from the pool ejected by the cleaner into the bag. The debris bag also includes a float coupled to the body. The float is positioned outside of and adjacent to the debris collection region of the bag so as to be separate from the lower end. | 08-28-2008 |
