Vehicle control apparatus
In a control apparatus of a vehicle according to an embodiment of the present invention, there is a failsafe control that blocks power transmission from a drive source to drive wheels by releasing clutches of an automatic transmission when there is a shift switching failure. In consideration of the fact that when a working oil temperature of the automatic transmission is low (below the freezing point, for example), the viscosity of the working oil is high and response for power blocking is poor, in a case where an oil temperature at the time of a shift switching request is low (steps ST2 and ST3), the power transmission is blocked by releasing the clutches of the automatic transmission at the same time as the shift switching request (step ST11). Thus, a clutch release delay occurring when there is a shift switching failure at a low oil temperature is prevented. |

Therefore, at the level ratio, the portion corresponding to the diffraction sound is flat and a data level becomes high locally in only the portion corresponding to the collection sound. By using this, the sound collection beam signal including the collection sound is detected. |

System and method for compensating memoryless non-linear distortion of an audio transducer
A low-cost, real-time solution is presented for compensating memoryless non-linear distortion in an audio transducer. The playback audio system estimates signal amplitude and velocity, looks up a scale factor from a look-up table (LUT) for the defined pair (amplitude, velocity) (or computes the scale factor for a polynomial approximation to the LUT), and applies the scale factor to the signal amplitude. The scale factor is an estimate of the transducer's memoryless nonlinear distortion at a point in its phase plane given by (amplitude, velocity), which is found by applying a test signal having a known signal amplitude and velocity to the transducer, measuring a recorded signal amplitude and setting the scale factor equal to the ratio of the test signal amplitude to the recorded signal amplitude. Scaling can be used to either pre- or post-compensate the audio signal depending on the audio transducer. |

Audio signal processing device and audio signal processing method for specifying sound generating period
Even in a state that the change of an environmental noise cannot be anticipated, a sound generating period in an audio signal can be specified with high accuracy. Sound in an audio space in which an audio signal processing system 1 is disposed is always collected by a microphone 20 and inputted to an audio signal processing device 10 as an audio signal. Before a user carried out a prescribed operation, the audio signals inputted from the microphone 20 are sequentially stored in a first buffer 121. After the prescribed operation is carried out, the audio signals are sequentially stored in a second buffer 122. A specifying part 114 considers the level of the audio signal stored in the first buffer 121 as the level of the environmental noise and the level of the audio signal sequentially stored in the second buffer 122 as the level of sound generated at a current time to calculate an S/N ratio. The specifying part 114 sequentially decides whether or not the calculated S/N ratio satisfies a prescribed condition to specify the sound generating period in the audio signal. |

Offspeed playback in a video editing system of video data compressed using long groups of pictures
An editing system handles offspeed and full speed playback of long GOP compressed video information by having one decoder for full-speed or slower forward playback of long GOP compressed motion video information, and a second single-frame, stateless decoder for use for off-speed playback. When compressed data is read from a file, the compressed data for at least one complete group of pictures is read into a buffer, herein called a compressed data buffer. A data structure, herein called a frame ring, is constructed to describe each image in the compressed data buffer. The single-frame, stateless decoder receives decompression parameters in addition to the compressed data for each image from this buffer. If the compressed data is a B-frame or P-frame, then uncompressed data for any other images (i.e., reference frames) required by the decoder to decompress the frame also is input to the single-frame, stateless decoder. If the uncompressed data for the reference frames is not already in a cache, these reference frames are decompressed and the uncompressed data for the reference frames as used by the decoder is stored in the cache prior to the decompression of the B-frame or P-frame. |

System and method for adaptive correction to phased array antenna array coefficients through dithering and near-field sensing
A system and method of adaptively correcting the excitation or receive coefficients for a phased array antenna. For a transmitting antenna, a sensor located in the near field of the antenna is used to sense the antenna transmission. A reference signal that represents the sensor response to a desired antenna transmission that is accomplished with predetermined excitation coefficients is determined. The magnitudes and phases of the excitation coefficients are modified in a predetermined manner to create a modified antenna transmission. An actual signal that represents the sensor response to the modified antenna transmission is then determined. The excitation coefficients are then corrected using the differences between the reference signal and the actual signal, such that the modified antenna transmission becomes closer to the desired antenna transmission. The method and system also apply to a receiving antenna. |

Method for cleaning signals for centralized antijamming
The present invention relates to a method for cleaning signals for centralized antijamming. The invention makes it possible to provide as many cleaned antenna channels as sub-arrays with limited computational requirements. The method proceeds in two steps. Initially, an antijamming matrix is computed. This matrix depends on the noise covariance matrix, on a weighting vector representing the form of the desired antenna pattern on reception in an unjammed environment, and on constraints for preserving the shape of this antenna pattern. Subsequently, the signals arising from the antenna sub-arrays undergo a linear recombination effected by the antijamming matrix. The antijamming method is termed centralized since the data necessary for the antijamming processing are concentrated in the lone antijamming matrix. The invention applies notably to radar systems, notably to airborne radar systems. |

Proxy remote control
A method includes receiving, at a proxy remote control signal receiver device, first control data from a remote control device that is associated with a first device. The first control data is prevented from being received at a remote control signal receiver associated with the first device. The first control data is associated with execution of a first action at the first device. The method includes communicating the first control data from the proxy remote control signal receiver device to a proxy controller and receiving second control data from the proxy controller. The second control data is associated with execution of a second action at the first device that is different from the first action. The second control data is communicated to the first device via the proxy remote control signal receiver device. The incoming commands may be superseded with another command set destined for the second device or ignored based on the context of the incoming commands. |

Apparatus and methods for processing remote control information
A message transmitting signal comprised of a sequence of high level and low level pulses arranged to provide a message, such as the IR bit pattern output by a remote control device, is analysed. Distinct durations during which pulses are at a high level are formed into a first table and distinct durations during which the pulses are at low level are formed into a second table. An index is linked to the first and second tables, the index identifying the order, level and distinct duration of the pulses in the signal. The index can be categorised to identify the protocol of the message and can be used to recognise protocols and, in a universal remote control device, to generate message transmitting signals. |

Method and system for variable resolution data conversion in a receiver
A received plurality of signals may be filtered to select an in-band signal and/or an out-of-band. A signal strength of the selected signal(s) may be measured. A resolution of an analog-to-digital converter may be controlled based on the measured signal strength(s). The selected in-band signal may be converted to a digital representation via the analog-to-digital converter. The resolution may be decreased when the strength of the in-band signal is higher, and increased when the strength of the in-band signal is lower. The resolution may be increased when the strength of the out-of-band signal is higher, and decreased when the strength of the out-of-band signal is lower. A signal-to-noise ratio and/or dynamic range of the selected signal(s) may be determined based on the measured signal strength(s), and may be utilized to adjust the resolution of the analog-to-digital converter. |
