Abstract: A vehicle-mounted apparatus includes a cluster display unit attached to an instrument panel and a HUD. The vehicle-mounted apparatus determines a running state of the vehicle and adjusts the focal length in the HUD such that the position of a virtual image of a projected image is near the cluster display unit or is a forward position on the windshield.

Abstract: A movement route generating apparatus includes an angle calculating unit calculating an angle formed by a vehicle travel direction at a target position compared with that at the current position, a graph generating unit generating a graph that has most gentle inclinations by plotting the curvature of a travel trajectory matching the steering angle of the vehicle and a distance traveled on two axes, under the condition that the area of a graph generated in correspondence to a travel trajectory from the current position to the target position is equal to the angle and other conditions, and a route setting unit setting a travel trajectory represented by the graph as the movement route of the vehicle. Accordingly, a travel trajectory with the smallest degree of change in curvature per unit distance traveled, that is, a low horizontal angular velocity caused by vehicle steering, can be set as a movement route.

Abstract: A head-up display device displays a virtual image in front of a vehicle, and includes a memory configured to store a program, and a processor. The processor is configured to execute the program and perform a process that includes acquiring information related to a target object recognized from image data received from an imaging device that captures a view in front of the vehicle, generating a projection image to be projected as the virtual image, determining a display position of the projection image along a traveling direction of the vehicle, based on the information related to the target object, using the target object as a reference, transforming the projection image into a support image viewed from a predetermined direction, and projecting the support image in front of the vehicle.

Abstract: A cap member is attached to an opening end portion of a bobbin on which a voice coil is wound. The cap member includes a bobbin reinforcement portion including a cylindrical portion and a bottom surface portion. The cylindrical portion opposes an inner surface of the bobbin, and the cylindrical portion and the inner surface of the bobbin are fixed to each other in at least a vibration plate fixed portion and a damper member fixed portion.

Abstract: A power system includes a voltage detection IC which outputs a reset signal to a microcomputer when an input voltage is equal to or lower than a reset release voltage, releases outputting of the reset signal when the input voltage exceeds the reset release voltage, and outputs the reset signal to the microcomputer again after the input voltage exceeds the reset release voltage when the input voltage is equal to or lower than a reset detection voltage which is lower than the reset release voltage and a voltage conversion circuit which sets a first voltage associated with a change of a power voltage as the input voltage before start of operation of the microcomputer and sets a second voltage which is associated with a change of the power voltage and is lower than the first voltage as the input voltage after the start of operation the microcomputer.

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: An in-vehicle device includes an operation screen display unit that displays a specific operation screen containing an operation key for causing the in-vehicle device to perform a specific action, an operation key moving unit that moves the operation key in a predetermined direction, a camera and a movement recognition unit that detect a movement of part of a body of a user or a movement of an operation member held by the user, and an operation selection unit that, when a movement direction of the operation key matches a direction of the detected movement of the user, selects the operation key moved by the operation key moving unit.

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: An audio apparatus includes a signal processor, a power amplifier, a speaker, and a controller. A current consumption prediction unit in the controller predicts current consumption on the basis of a monitoring result of an output level monitoring unit in the signal processor and/or a monitoring result of a power supply voltage monitoring unit in the controller. A limiter control unit in the controller controls a limiter in the signal processor in a normal mode or a current limiting mode on the basis of predicted current consumption. In the current limiting mode, the limiter is controlled so that an attenuation speed higher than that in the normal mode and a threshold value smaller than that in the normal mode are obtained.
