20120139816 | IN-VEHICLE DISPLAY MANAGEMENT SYSTEM - A system and method for displaying information within a vehicle is described. The system includes at least one sensing device detecting a set of data associated with the vehicle, driver, or surroundings, which is processed using a processing unit for identifying a set of information to be displayed. The system also includes a set of display devices coupled to the vehicle. A router selects one or more display devices for displaying the display element based on a set of conditions. A display control unit generates an appropriate display element for the set of information identified and the selected display. | 06-07-2012 |
20130083195 | POLARIZATION-BASED ANTI-BLINDING NIGHT VISION SYSTEM, VEHICLE COMPRISING SAME, AND METHOD THEREFOR - A night vision system has a night vision illuminator, an imaging apparatus, and a first light conditioning structure. The night vision illuminator is configured for illuminating a space with near-infrared (NIR) light that is linearly polarized in a direction substantially parallel with a first polarization axis. The imaging apparatus is configured for creating an electrical representation of an image defined by NIR light received thereby. A field of view of the imaging apparatus includes at least a portion of the space illuminated with the NIR light of the night vision illuminator. The first light conditioning structure is configured for linearly polarizing in a direction substantially non-parallel with respect to the first polarization axis the NIR light received by the imaging apparatus. | 04-04-2013 |
20130204457 | INTERACTING WITH VEHICLE CONTROLS THROUGH GESTURE RECOGNITION - A gesture-based recognition system obtains a vehicle occupant's desired command inputs through recognition and interpretation of his gestures. An image of the vehicle's interior section is captured and the occupant's image is separated from the background, in the captured image. The separated image is analyzed and a gesture recognition processor interprets the occupant's gesture from the image. A command actuator renders the interpreted desired command to the occupant along with a confirmation message, before actuating the command. When the occupant confirms, the command actuator actuates the interpreted command. Further, an inference engine processor assesses the occupant's state of attentiveness and conveys signals to a drive assist system if the occupant in inattentive. The drive-assist system provides warning signals to the inattentive occupant if any potential threats are identified. Further, a driver recognition module readjusts a set of vehicle's personalization functions to pre-stored settings, on recognizing the driver. | 08-08-2013 |

20090182556 | PITCH ESTIMATION AND MARKING OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, a method of processing a signal representing speech can comprise receiving a frame of the signal representing speech, classifying the frame as a voiced frame, and parsing the voiced frame into one or more regions based on occurrence of one or more events within the voiced frame. For example, the one or more events can comprise one or more glottal pulses. The one or more regions may collectively represent less than all of the voiced frame. | 07-16-2009 |
20090271183 | PRODUCING TIME UNIFORM FEATURE VECTORS - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a frame of the signal representing speech, the frame comprising a voiced frame. One or more cords can be extracted from the voiced frame based on occurrence of one or more events within the frame. For example, the one or more events comprise one or more glottal pulses. The one or more cords can collectively comprise less than all of the frame. The one or more cords can be normalized on a time basis. For example, each of the one or more cords can begin with onset of a glottal pulse and extend to a point prior to an onset of neighboring glottal pulse but may exclude a portion of the frame prior to the onset of the neighboring glottal pulse. | 10-29-2009 |
20090271196 | CLASSIFYING PORTIONS OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a frame of the signal representing speech. The frame can be classified as unvoiced or voiced based on occurrence of one or more events within the frame. For example, the one or more events can comprise one or more glottal pulses. In response to classifying the frame as voiced, the frame can be processed. | 10-29-2009 |
20090271197 | IDENTIFYING FEATURES IN A PORTION OF A SIGNAL REPRESENTING SPEECH - Methods, systems, and machine-readable media are disclosed for processing a signal representing speech. According to one embodiment, processing a signal representing speech can comprise receiving a region of the signal representing speech. The region can comprise a portion of a frame of the signal representing speech classified as a voiced frame. The region can be marked based on one or more pitch estimates for the region. A cord can be identified within the region based on occurrence of one or more events within the region of the signal. For example, the one or more events can comprise one or more glottal pulses. In such cases, cord can begin with onset of a first glottal pulse and extend to a point prior to an onset of a second glottal pulse. The cord may exclude a portion of the region of the signal prior to the onset of the second glottal pulse. | 10-29-2009 |

According to one embodiment, processing a signal representing speech can comprise receiving a first frame of the signal, the first frame comprising a voiced frame. One or more cords can be extracted from the voiced frame based on occurrence of one or more events within the frame. For example, the one or more events can comprise one or more glottal pulses. The one or more cords can collectively comprise less than all of the frame. For example, each of the cords can begin with onset of a glottal pulse and extend to a point prior to an onset of neighboring glottal pulse but may exclude a portion of the frame prior to the onset of the neighboring glottal pulse.

20110218695 | POSITION ENCODER WITH PROGRAMMABLE TRIGGER OUTPUT SIGNAL - A position encoder provides one or more trigger outputs based on position signals developed within the encoder, in addition to traditional position output signals used by other system components such as a motion controller. The trigger outputs may be used directly by a triggered device, bypassing the motion controller and obviating any separate trigger generation electronics. The trigger output(s) can be fully synchronous with the encoder's position output signal(s) with essentially no latency or jitter, increasing accuracy and providing improved system performance. The trigger functionality can be incorporated in a variety of encoder types (e.g., absolute and incremental) and technologies (optical, magnetic, inductive etc.), and used in conjunction with different position output signal formats (e.g., quadrature, serial). | 09-08-2011 |
20150048242 | PHASE ESTIMATION METHOD AND APPARATUS THEREFOR - Phase estimation apparatus processes sensor signals from sensors to estimate a phase of a periodically varying state of an object, such as position of a moving object. A phase estimation processor applies a first correlation calculation to simultaneously collected samples of the sensor signals to generate first quadrature values, where the first correlation calculation employs variable calculation values, and applies a phase calculation to the first quadrature values to generate the phase estimation. A pre-quadrature calibration circuit applies respective second correlation calculations to respective sequences of samples of the sensor signals individually to generate second quadrature values for each of the sensor signals, and applies phase and/or magnitude calculations to the sets of second quadrature values to generate the variable calculation values for the first correlation calculation, thereby compensate for the error component and improve accuracy of the estimated phase. | 02-19-2015 |
