Networked device management data collection
A data collection workflow architecture can streamline data collection from a heterogeneous network and leverage plug-ins of various technologies for data collection from the heterogeneous network. The data collection workflow architecture uses a workflow definition which is an abstracted series of data collection tasks. The workflow definition expresses the data collection tasks at a level abstracted away from the underlying implementation to increase the ease and efficiency of managing and maintaining data collections on a heterogeneous network. A workflow engine transforms each of the higher level expressions of data collections tasks into task definitions that can be passed to a plug-in engine. The task definition can be considered the abstracted process level expression of a data collection task with variable values injected into it. The plug-in engine hooks a task definition into an implementation of the task definition and executes or interprets the task definition implementation with the variable values. |

A low power voltage regulator includes a weighted transistor array having a plurality of transistor switches with a total conductance of G, corresponding to bits from a MSB to LSB. A transistor switch corresponding to the MSB has a conductance of G/2 and remaining bits have a consecutive descending conductance of G/2N to the LSB, and search time takes a low number of cycles by starting with the MSB. A redundant LSB transistor switch has the same G/2N conductance of the LSB. The redundant LSB is used to correct steady-state errors, and a proportional derivative controller compensates output voltage. The compensation in a method eliminates an output pole of the voltage regulator to provide a stable voltage regulator operation irrespective of load current, load capacitance, or sampling frequency. Voltage can be regulated via the additional LSB below the resolution limit via pulse width modulation. |

A first of these nodes is coupled, typically directly and with no energy-storing bulk capacitor, to a rectifier that supplies rectified power from an alternating current power source. A second node is also supplied power from the rectifier, but is coupled to a bulk capacitor that can store and supply energy as needed. The techniques disclosed herein use the first node to supply power to the transformer when feasible, and use the second node, and its associated bulk capacitor, to supply power otherwise. In so doing, the energy storage requirements of the bulk capacitor may be reduced, meaning that the capacitance and associated size of the bulk capacitor may be reduced relative to other power converter circuits. |

A video reproduction time setting unit sets a reproduction time when reproduction is performed at the lower frame rate as a video reproduction time. An audio reproduction time setting unit sets an audio reproduction time at constant intervals for sounds recorded at constant intervals outside the detection period and sets an audio reproduction time in synchronization with the video reproduction time corresponding to the detection frame relative to sound recorded in the detection period. |

Audio signal quality enhancement based on quantitative SNR analysis and adaptive Wiener filtering
An audio signal enhancement method includes: acquiring an audio signal; estimating a signal-to-noise ratio (SNR) of an audio frame of the audio signal; determining a SNR threshold for the audio frame; selecting an audio signal processing technique according to a comparison of the SNR threshold to the estimated SNR of the audio frame; filtering the audio frame using a Wiener filter applying the selected signal processing technique; and outputting the audio frame filtered using the Wiener filter applying the selected signal processing technique. A first-in, first-out (FIFO) signal processing technique is selected when the estimated SNR of the audio frame is less than the SNR threshold, and a log-energy voice activity detection (VAD) signal processing technique is selected when the estimated SNR of the audio frame is greater than the SNR threshold. |

Method and device for processing a signal supplied by a sensor for measuring the pressure existing in a cylinder
Disclosed is a method of processing a periodic voltage signal, called the input signal, relating to the pressure existing in a combustion chamber of a cylinder of an internal combustion engine. The method includes a step (E6) of determining a second instant of unlocking of the base signal during a second peak phase, a step (E7) of determining a second instant of locking, which is subsequent to the second instant of unlocking and for which the input signal is in the plateau phase consecutive to the second peak phase, and a step (E8) of generating a base signal between the second instant of unlocking and the second instant of locking on the basis of a slope value of a straight line determined during a first peak phase between a first instant of unlocking and a first instant of locking. |

Stereo parameters for stereo decoding
An apparatus includes a receiver and a decoder. The receiver is configured to receive a bitstream that includes an encoded mid channel and a quantized value representing a shift between a reference channel associated with an encoder and a target channel associated with the encoder. The quantized value is based on a value of the shift. The value of the shift is associated with the encoder and has a greater precision than the quantized value. The decoder is configured to decode the encoded mid channel to generate a decoded mid channel and to generate a first channel based on the decoded mid channel. The decoder is further configured to generate a second channel based on the decoded mid channel and the quantized value. The first channel corresponds to the reference channel and the second channel corresponds to the target channel. |

Associating a user voice query with head direction
A method and apparatus for associating a query to a direction is provided herein. During operation, a virtual partner will attempt to determine a direction the query originated from. When answering the query, the virtual partner will adjust multiple speaker outputs so that the reply is perceived to come from the same direction as the query originated from. Additionally, if another follow-on query is made from a particular direction, the follow-on query will be associated with the prior query originating from the same particular direction. |

Dynamic gazetteers for personalized entity recognition
In speech processing systems personalization is added in the Natural Language Understanding (NLU) processor by incorporating external knowledge sources of user information to improve entity recognition performance of the speech processing system. Personalization in the NLU is effected by incorporating one or more dictionaries of entries, or gazetteers, with information personal to a respective user, that provide the user's information to permit disambiguation of semantic interpretation for input utterances to improve quality of speech processing results. |
