20110082845 | DYNAMIC RULE CREATION AND CACHING - A condensed version of a plurality of rules for one or more forms being used by a user is loaded from a database. The condensed version of the plurality of rules is stored in cache memory of a computing device. When an event occurs, a rules engine determines if a condensed version of the rule is stored in cache memory. If a rule is not applicable, the rules engine does not query the database. If a rule is applicable, the rules engine determines if an action should be taken for the event. If no action is to be taken, the database is not queried for the rule. If an action is to be taken, the database may be queried for information for the rule to allow performing of the action or if the action is included in the condensed version, the action is performed without querying the database. | 04-07-2011 |

20110052209 | High-Speed Multi-Level Electronic Signal Generation for Optical Communications - A method of processing data is provided that includes receiving a plurality of binary electronic signals and generating an optical signal by a number of lasers that is equal to or greater than the number of binary electronic signals. The optical signal is generated at one of a plurality of intensity levels, and each intensity level represents a particular combination of bit values for the plurality of binary electronic signals. The optical signal is converted into an electronic signal having the plurality of intensity levels. An apparatus for processing data is provided that includes a plurality of lasers configured to emit light at a plurality of frequencies, and a plurality of modulators configured to receive a plurality of binary electronic signals and to modulate the light emitted by the lasers. An apparatus for transmitting data is provided that includes a photo receiver and an electronic signal generator. | 03-03-2011 |

20150162991 | RECEIVER FOR COHERENT OPTICAL TRANSPORT SYSTEMS BASED ON ANALOG SIGNAL PROCESSING AND METHOD THEREOF - The present invention discloses a receiver for coherent optical transport systems based on analog signal processing and the method of recovering transmitted data by processing signals in electronic domain. In the present invention, high-speed electrical signals obtained from optical-to-electrical converters which carry transmitted data information in a coherent transport system are jointly processed in analog domain itself without converting these signals to the digital domain using high speed ADCs. Different processing steps which may include carrier phase & frequency offset recovery and compensation, polarization mode dispersion and/or chromatic dispersion, clock & data recovery and deserialization may be performed while keeping the information signals in analog domain itself. | 06-11-2015 |

20100201345 | TIME STRETCH ENHANCED RECORDING SCOPE - A time-stretched enhanced recording scope (TiSER) is described using time stretch analog-to-digital conversion in a real-time burst mode. A chirped optical signal is modulated in response to receiving segments of an input signal. The optical signal with its modulated input signal, is stretched through an optical medium and digitized to represent the waveform segment. TiSER provides ultra-fast real-time sampling within short segment bursts of the original input signal while providing an ability to detect non-repetitive events. Methods and apparatus are also described for providing real-time information about inter-symbol information (ISI), rapidly determining bit-error rates (BER), performing time-domain reflectometry (TDR), generating eye diagrams for serial data, facilitating digital correction of data, clock recovery, optical carrier phase recovery, and otherwise increasing the speed and/or accuracy of a diverse range of high-speed signal measurement and processing activities. | 08-12-2010 |
