20140129226 | PRIVACY-SENSITIVE SPEECH MODEL CREATION VIA AGGREGATION OF MULTIPLE USER MODELS - Techniques disclosed herein include systems and methods for privacy-sensitive training data collection for updating acoustic models of speech recognition systems. In one embodiment, the system locally creates adaptation data from raw audio data. Such adaptation can include derived statistics and/or acoustic model update parameters. The derived statistics and/or updated acoustic model data can then be sent to a speech recognition server or third-party entity. Since the audio data and transcriptions are already processed, the statistics or acoustic model data is devoid of any information that could be human-readable or machine readable such as to enable reconstruction of audio data. Thus, such converted data sent to a server does not include personal or confidential information. Third-party servers can then continually update speech models without storing personal and confidential utterances of users. | 05-08-2014 |

20130191070 | SYSTEM AND METHOD FOR INSPECTING RAILROAD TIES - A system for inspecting railroad ties in a railroad track includes a light generator, an optical receiver and a processor. The light generator is oriented to project a beam of light across the railroad track while moving along the railroad track in a travel direction. The optical receiver is oriented to receive at least a portion of the beam of light reflected from the railroad track and configured to generate image data representative of a profile of at least a portion of the railroad track. The processor is configured to analyze the image data by applying one or more algorithms configured to find boundaries of a railroad tie and determine one or more condition metrics associated with the railroad tie. | 07-25-2013 |

20120139438 | LED Drivers and Control Methods - A method of operating an LED driver including a power converter to generate an output current for powering an LED and to provide active power factor correction is disclosed. The power converter is coupled between an input to receive a rectified AC voltage and an output for providing the output current to the LED. The method includes operating the power converter at a substantially fixed frequency in an open loop mode based on a current through the inductive element and the rectified AC voltage. LED drivers operable in accordance with the disclosed method are disclosed. | 06-07-2012 |
20120139442 | Mains Dimmable LED Driver Circuits - A method of controlling a dimming level of one or more light emitting diodes (“LEDs”) includes receiving a phase cut dimming signal having a pulse width and frequency, generating a PWM signal having a duty cycle and frequency corresponding to the pulse width and frequency, respectively, of the phase cut dimming signal, and controlling a power converter coupled to the one or more LEDs with the generated PWM signal so that the dimming level of the one or more LEDs is a function of the duty cycle of the generated PWM signal. Example circuits for practicing this method and alternative methods are also disclosed. | 06-07-2012 |
