Abstract: An error path characteristic model correction control unit determines the deviation of the phase of an actual transfer function from the phase of an error path characteristic model, from a cross correlation between an error signal output from a microphone and a signal in which the error path characteristic model is applied to a noise cancellation sound to be output and a cross correlation between the error signal and a signal in which a transfer function having a phase characteristic deviating by +90 degrees from the phase characteristic of the error path characteristic model is applied to the noise cancellation sound. The error path characteristic model correction control unit then corrects the error path characteristic model so that the determined deviation is reduced to ±90 degrees.

Abstract: An upper limit of a frequency range of audio indicated by input audio data is detected. A representative point extraction unit downsamples the input audio data to a sampling rate set to be less than or equal to twice the detected upper limit to obtain representative-point audio data. An interpolation processing unit upsamples the representative-point audio data by using a fractal interpolation function (FIF) that uses a mapping function calculated by a mapping function calculation unit, while using the input audio data, if necessary, to generate high-frequency interpolated audio data.

Abstract: A method and system for unlocking a reserved vehicle designed to encode an access code assigned by a remote server to a Morse code or pattern by a control box or a head unit provided in the reserved vehicle. The Morse code or pattern is generated in a form of a sound signal or a light signal with use of a vehicle horn or headlight. The Morse code or pattern in sound or light is detected by a pre-existing mobile device, typically, a smartphone of a user without requiring any specific access card or reader. The detected Morse code or pattern is decoded back to the access code or converted an FFT signal by the mobile device and is sent to the server for verification. When successfully verified, the server sends an unlock command to the reserved vehicle so that the user can gain access to the reserved vehicle.

Abstract: An in-vehicle device is capable of coupling to a portable terminal, receives content data played by the portable terminal that has been coupled, and outputs the content data that has been received. While music is being played back by the portable terminal, the in-vehicle device estimates a remaining battery level of the portable terminal after playback of the music to be next played back finishes, and provides, when the estimated value is a threshold value or less, notification of the remaining battery level before the playback of music starts and/or after the playback finishes.

Abstract: When an unmanned aerial vehicle flies in accordance with a planned route that is set in advance on the basis of a position of a GPS receiver measured by a measurement unit and the measurement accuracy detected by a measurement accuracy detection unit has decreased to be less than a predetermined value, a flight control unit performs control so that the unmanned aerial vehicle flies along a route different from the planned route. Moreover, when flying along the planned route lowers the measurement accuracy, the unmanned aerial vehicle is caused to fly along the route different from the planned route. Therefore, the flight can be continued while the position is measured with the measurement accuracy secured.

Abstract: An acoustic apparatus may include a frame having an axially-opening annular open portion; a diaphragm supported by being attached to the annular open portion via a flexible edge member so as to be capable of vibrating in the axial direction; and a driving unit connected, at a connection portion at a center portion of the diaphragm, to the diaphragm to apply an axial-direction driving force to the diaphragm. The diaphragm includes first and second diaphragms that are mutually adjacent in the axial direction and joined together. When viewed in the axial direction, the second diaphragm has an outer diameter smaller than that of the first diaphragm. Each diaphragm includes a sheet member having an orientation dispersion structure including a shape-anisotropic filler dispersed in a resin with the long axis thereof oriented in a predetermined direction. The orientation directions of the sheet members of the first and second diaphragms mutually intersect.

Abstract: A first fixed filter extracts high-frequency and low-frequency sound signals outside the audible band, and a level integrator integrates levels of the sound signals to obtain a first integrated value. With a second fixed filter, the level integrator integrates levels of sound signals in a low frequency band within the audible band to obtain a second integrated value. A control unit determines whether the high-frequency sound signals are dominant by comparing the first integrated value with the second integrated value. When the high-frequency sound signals are dominant, the control unit attenuates high-frequency speaker drive signals using a variable filter.

Abstract: A vehicle speaker system includes a speaker having a diaphragm that generates a sound pressure, a frame that supports the diaphragm vibratably, and a driving unit attached to the frame to drive the diaphragm. A position of the speaker relative to a partition separating a vehicle-cabin inner space and an engine compartment inner space is determined so that the sound pressure generated by an action of the diaphragm passes through an opening in the partition. A shield member is provided with at least a part thereof being located between the speaker and an obstacle generation source located in the engine compartment inner space to obstruct an operation of the speaker. An open part allowing a first space provided between the speaker and the shield member to communicate with the engine compartment inner space is provided in such a direction as not to be directed toward the obstacle generation source.

Abstract: A guide route setting apparatus may include a lane-basis route setting unit configured to follow lane networks in a direction of a vehicle position from a starting point at an end of the lane networks and to set lane networks connecting from the end to a lane where the vehicle position presents a lane-basis guide route based on lane network data acquired by a lane network data acquisition unit along a preset road-basis guide route. A disadvantage that lane guidance is not made until just before a guide intersection is avoided by setting the road-basis guide route for a section from the end of the lane networks to the vehicle position, indicated by the lane network data acquired not only when the vehicle approaches the guide intersection but also along the road-basis guide route.

Abstract: A current location measured by a GPS receiver is defined as a base location. Individual points fairly near to the base location that are located on roads whose distances from the base location fall within a predetermined distance are set as candidate points. A distance between the base location and a candidate point to be evaluated is calculated. In a case where the distance is larger than a threshold value statistically estimated from a history of calculated distances between the base location and previously set candidate points that draw a trajectory on a road leading to the candidate point to be evaluated, the threshold value defining a rough upper limit of a distribution range of distances between the base location and the candidate points, it is judged that a true current location is not located on the road in which the candidate point is located.

The loudspeaker may be disposed in the cowl box such that sound pressure generated by the diaphragm is emitted to the vehicle interior space.
