Abstract: An input device includes a strain generation body having an operation shaft, a load sensor configured to detect a load in a horizontal direction applied to the operation shaft, an operation member disposed in an upper portion of the operation shaft, the operation member being configured to be operated in a pressing operation, a switch section configured to detect the pressing operation performed by using the operation member, and a controller configured to output a detection value of the load in the horizontal direction detected by the load sensor and a detection value of the pressing operation detected by the switch section to an external device. The controller is configured not to update the output value of the detection value of the load in the horizontal direction while the pressing operation is being detected by the switch section.

Abstract: Loudspeaker enclosures that support improved acoustic radiation efficiency at low audible frequencies without compromising acoustic radiation efficiency at mid and high audible frequencies. Embodiments include enclosures having a primary chamber and a secondary chamber acoustically coupled to the primary chamber via a passive radiator. The geometrical characteristics of the secondary chamber and the corresponding air plenum are tailored for enhanced efficiency at low frequencies.

Abstract: A transducer includes a flexible substrate, a piezoelectric element formed on a surface of the flexible substrate, and a support member, in which holes are formed, having a higher rigidity than the flexible substrate. The surface of the flexible substrate has an element region in which the piezoelectric element is continuous in a planar direction of the piezoelectric element. The support member is stacked to the flexible substrate in a manner such that the holes face the element region. The flexible substrate is freely movable in each of the holes, and a region of the flexible substrate corresponding to a region other than the holes of the support member is fixed to the support member.

Abstract: A vibration generating device includes a movable body in a housing, supported to vibrate along a first direction; a bracket attached to the housing, including a body plate extending in a second direction and a first reinforcing plate extending in a third direction from one end of the body plate in the second direction; a coil attached to the body plate, including main-bundle-wire-parts in the second direction connected by a sub-bundle-wire-part; and a magnet attached to the movable body on another side of the coil in the third direction, generating a magnetic flux toward the main-bundle-wire-part. One end of the magnet in the second direction is inside one end of the sub-bundle-wire-part in the second direction. The first reinforcing plate extends from inside one end of the sub-bundle-wire-part in the second direction and outside one end of the magnet in the second direction, toward another side in the third direction.

Abstract: Multiple infrared-light LEDs are aligned in the left-right direction, below the display surface of a display, and the approach position Gx of an object approaching the display surface is calculated from the distribution of the respective intensities of infrared light beams emitted from the LEDs in a front, oblique direction. Based on the horizontal coordinate Tx of a touch position on the touch panel and the approach position Gx, a user in a driver's seat, positioned right of the display, is identified as the touching operator of the touch panel if the approach position Gx is located Th1 or more apart to the right from the coordinate Tx, and a user in a passenger's seat, positioned left of the display, is identified as the touching operator if the approach position Gx is located Th1 or more apart to the left from the coordinate Tx.

Abstract: An angle measuring device includes an antenna device having antenna elements equally spaced along a first axis and a second axis, respectively, a selecting unit that selects phase differences with which a variance thereof becomes a predetermined value or less, from a plurality of phase differences of signals received from a transmission device by the antenna elements, an azimuth angle computing unit that computes an azimuth angle of the transmission device from a ratio of a first phase difference between signals received by two antenna elements spaced by a predetermined distance along the first axis and a second phase difference between signals received by two antenna elements space by the predetermined distance along the second axis, and an elevation angle computing unit that computes an elevation angle of the transmission device, based on the computed azimuth angle and the first or second phase difference.

Abstract: A rotation angle detecting method includes measuring a current flowing through a motor, and obtaining a rotation angle of the motor based on a value of the measured current. The obtaining of the rotation angle of the motor includes obtaining the rotation angle in an inertial rotation of the motor based on a rotational angular velocity of the motor immediately before a first time point, a time period from the first time point to a second time point, and a time period from the second time point to a third time point. The first time point is a time point at which driving of the motor is stopped, the second time point is a time point at which a polarity of the value of the measured current is inverted, and the third time point is a time point at which the value of the measured current becomes zero.

Abstract: A decorative laminate for transmitting light includes a light-permeable substrate, a light adjusting layer, an interference pigment print layer, and a black semi-transparent print layer. The light adjusting layer has, at a surface opposite from the substrate, an uneven part formed to match a design's shape shown by the interference pigment print layer. The interference pigment print layer has first light transmitting parts, through which the light is transmitted. The black semi-transparent print layer has second light transmitting parts, at positions at a main surface of the black semi-transparent print layer where, in plan view, the second light transmitting parts at least partially overlap the first light transmitting parts. The first light transmitting parts and the second light transmitting parts are voids in a coating layer and formed at a main surface of the interference pigment print layer and at the main surface of the black semi-transparent print layer, respectively.
