20120269523 | OPTICAL DIFFERENTIAL PHASE-SHIFT KEYED SIGNAL DEMODULATOR - A phase-shift keyed signal demodulator and method for demodulating is disclosed. An example demodulator includes N filters that receive inputs from a splitter and include transmission functions offset from one another. N pairs of photodiodes receive the transmitted and reflected beams from each filter and a decoder converts the outputs of the pairs of photodiodes to one or more data symbols. | 10-25-2012 |
20130094797 | Optical Transmitter With Tunable Chirp - An optical transmitter with chirp control includes an input polarizer having an input that receives an optical signal. The input polarizer polarizes the optical signal along an input polarization axis. A Mach-Zehnder modulator includes an optical input that is coupled to an output of the input polarizer and an electrical input that receives a modulation signal. The Mach-Zehnder modulator modulates the optical signal with the modulation signal. The input polarization axis of the input polarizer is chosen to achieve a desired chirp of the modulated optical signal. An output polarizer is coupled to the output of the Mach-Zehnder modulator. The output polarizer polarizes the modulated optical signal along a desired output polarization axis that combines TE and TM mode polarizations. | 04-18-2013 |

20090060526 | OPTICAL FM SOURCE BASED ON INTRA-CAVITY PHASE AND AMPLITUDE MODULATION IN LASERS - An optical transmitter is discloses having a gain section and a phase section. The phase section is modulated to generate a frequency modulated signal encoding data. The frequency modulated signal is transmitted through an optical spectrum reshaper operable to convert it into a frequency and amplitude modulated signal. In some embodiments, a driving circuit is coupled to the phase and gain sections is configured to simultaneously modulate both the phase and gain sections such that the first signal is both frequency and amplitude modulated. | 03-05-2009 |
20090208225 | VARIABLE OPTICAL ATTENUATOR INTEGRATION INTO TRANSMITTER OPTICAL SUBASSEMBLIES - A small-scale VOA system includes a polarization rotator, a voltage multiplier circuit, and at least one transistor. The polarization rotator can be positioned within a TOSA along the emission axis of a corresponding optical signal source in addition to one or more polarizers. A microcontroller provides a first low voltage control signal to a voltage multiplier to generate a large voltage DC signal which is provided to the transistor. The transistor modulates the large voltage signal with a second control signal from the microcontroller to generate a large voltage AC signal for driving the polarization rotator. The polarization rotation of the polarization rotator can be altered depending on the applied large-voltage AC signal. As a result, the polarization rotator and one or more polarizers can variably attenuate signals emitted by the optical signal source or act as a shutter. | 08-20-2009 |
20110170171 | OPTICAL DIFFERENTIAL PHASE-SHIFT KEYED SIGNAL DEMODULATOR - A phase-shift keyed signal demodulator is disclosed including a filter positioned to receive an input beam, a first photodiode positioned to receive light reflected from the filter, and a second photodiode positioned to receive light transmitted through the filter. A difference between outputs of the first and second photodiodes is interpreted to determine a data value encoded in the input beam. In another embodiment N filters receive inputs from a splitter and include transmission functions offset from one another. N pairs of photo diodes receive the transmitted and reflected beams from each filter and a decoder converts the outputs of the pairs of photodiodes to one or more data symbols. | 07-14-2011 |

20080313076 | DOWNSTREAM CORRESPONDENT FOREIGN EXCHANGE (FX) BANKING - Systems and methods that enable real-time (or almost real-time) foreign exchange (FX) pricing via retail branch networks, wire room operations and cash management platforms are provided. Essentially, the systems and methods decouple the FX-infrastructure and enable downstream banks to effectively and efficiently access FX transaction services and infrastructure without the need to locally manage such an FX platform. In doing so, an FX generation component is employed in connection with standard downstream mechanisms to provide necessary information to a partner FX processing component. The partner FX processing component conveys information to the downstream environment while shielding the downstream entity from risks and costs involved in FX operations. | 12-18-2008 |

20140249452 | Freezing of Gait Cue Apparatus - A freezing of gait cue apparatus that provides a visual cue, and a method for providing a visual cue, upon detection of a gait irregularity. The gait irregularity, such as a freeze of gait (FOG) for sufferers of neurological diseases like Parkinson's disease, is determined by a processor in communication with a motion sensor worn by the sufferer. When the gait irregularity is determined the apparatus projects a laser light beam on the ground in front of the user of the apparatus to cue them to continue walking. | 09-04-2014 |
