20120016615 | METHOD FOR ADJUSTING A SELF MIXING LASER SENSOR SYSTEM FOR MEASURING THE VELOCITY OF A VEHICLE - The method is based on a determination of the orientation of the sensor to the surface moving with respect to the sensor and then acquiring data where the lateral velocity is small and the forward velocity is large. Then, the orientation of the sensor with respect to the direction of the forward velocity is determined and the velocity data subsequently measured are corrected using the measured orientation of the sensor with respect to the reference surface and the forward velocity direction. | 01-19-2012 |

20150050021 | Remote Modulation of Pre-Transformed Data - Methods, systems, and computer readable media can be operable to facilitate the remote modulation of pre-transformed data. In embodiments, a CMTS can provide pre-transformed data in the frequency domain to a transmitter or receiver. Multiple network components can be bypassed when pre-transformed data is delivered directly to a transmitter or receiver, thus improving the amount of network capacity and available network resources. In embodiments, pre-transformed data can be transformed and modulated at a receiver. | 02-19-2015 |

20120128361 | METHOD AND SYSTEM FOR A POLARIZATION MODE DISPERSION TOLERANT OPTICAL HOMODYNE DETECTION SYSTEM WITH OPTIMIZED TRANSMISSION MODULATION - An optical homodyne communication system and method in which a side carrier is transmitted along with data bands in an optical data signal, and upon reception, the side carrier is boosted, shifted to the center of the data bands, and its polarization state is matched to the polarization state of the respective data bands to compensate for polarization mode dispersion during transmission. By shifting a boosted side carrier to the center of the data bands, and by simultaneously compensating for the effects of polarization mode dispersion, the provided system and method simulate the advantages of homodyne reception using a local oscillator. The deleterious effects of chromatic dispersion on the data signals within the data bands are also compensated for by applying a corrective function to the data signals which precisely counteracts the effects of chromatic dispersion. | 05-24-2012 |
