20090000392 | FLOW SIMULATING CIRCUIT FOR TESTING OF FLOWMETERS - A simulating circuit ( | 01-01-2009 |
20090007625 | SYSTEM AND METHOD FOR FIELD CALIBRATION OF FLOW METERS - A calibration system for a flow meter includes a flow simulator, the flow simulator including a receiver configured to receive flow meter transducer signals from a flow meter. A simulation subsystem is configured to create simulated transit time signal pulses, and to transmit the simulated transit time signal pulses to the flow meter at preselected time intervals. A calibration subsystem is configured to receive from the flow meter a transit time differential value generated by the flow meter based on the simulated transit time signal pulses and output a calibration factor to the flow meter. | 01-08-2009 |

20110225257 | SYSTEMS AND METHODS FOR ITINERARY MESSAGING SERVICE - Messages are targeted to travelers based on travel itineraries. Targeting may also be based on real-time travel status information. The targeted messages communicate their purpose and priority to respective travelers within the context of the travel itineraries. A disclosed method includes accessing a travel itinerary database including a plurality of travel itineraries. Each travel itinerary is associated with a traveler and defines itinerary segments of a corresponding travel schedule. A message is associated with a set of targeting rules used to identify a subset of itineraries in the travel itinerary database. The targeting rules may be used with real-time travel status information to identify the subset of itineraries. | 09-15-2011 |

20140379278 | APPARATUS AND METHODS OF SPECTRAL SEARCHING USING WAVELET TRANSFORM COEFFICIENTS - Apparatus and methods of spectral searching that employ wavelet coefficients as the basis for the searching. The disclosed apparatus and methods employ a wavelet lifting scheme to transform spectroscopic data corresponding to an unknown pure material/mixture to a vector of wavelet coefficients, compare the wavelet coefficient vector for the unknown pure material/mixture with a library of wavelet coefficient vectors for known pure materials/mixtures, and identify the closest match to the unknown pure material/mixture based on the comparison of wavelet coefficient vectors. Because the wavelet lifting scheme can generate the wavelet coefficient vectors for the unknown pure material/mixture as well as the known pure materials/mixtures to conform to a desired compression level, the disclosed apparatus and methods can perform spectral searching with increased speed and reduced memory requirements, thereby making the disclosed apparatus and methods amenable for use in hand-held instruments for on-site material identification. | 12-25-2014 |
