Abstract: A safety support device includes an object detection camera and a radar device, which serve as detectors, and a controller that controls a dual-purpose speaker and a dual-purpose speaker, which serve as three-dimensional sound outputters, and a monaural speaker that serves as a sound outputter, based on detection information of a monitoring camera that serves as a monitor. The controller selects, in accordance with the positions of the ears of a driver, which are detected by the monitoring camera, whether to cause the dual-purpose speaker and the dual-purpose speaker to output a three-dimensional sound or to cause the dual-purpose speaker, the dual-purpose speaker, and the monaural speaker to output a sound.

Abstract: A safety assist device includes an object detection camera and a radar that detect the presence of an object and a position of the object on a lateral side or a rear side of an own vehicle, a vehicle speed sensor that detects a vehicle speed of the own vehicle, a driver's seat-side display and a passenger's seat-side display that are provided on a lateral side of a driver's seat inside the own vehicle, and a controller that causes the driver's seat-side display and the passenger's seat-side display to display a signal in response to the presence of the object detected by the object detection camera, the radar, and the like. The controller moves a position at which the signal is displayed toward a front side in a display range of the driver's seat-side display and the passenger's seat-side display in accordance with an increase in the vehicle speed detected.

Abstract: A detailed map is displayed on a display screen by using detailed map information. When a building BL on the detailed map is indicated, a user name list of the building is calculated from building information to display the user name list on a part of the display screen, and a detailed map MP displayed on another part of the display screen is inclined by a birds-eye process to be displayed. The indicated building BL is displayed three-dimensionally with a height corresponding to the number of its floors. When a user is specified from the user name list, the floor number of a floor on which the user is located is calculated from the building information. The floor is displayed by an L-shaped mark FL in the three-dimensionally displayed building such that the number of floors can be identified, and/or the floor number is displayed by the characters FLC.

Abstract: In a piezoelectric transformer device (36), a plurality of inner electrodes are stacked on each other on the left side. These inner electrodes are alternately connected to each other through interlevel connection conductors to constitute two inner electrode groups. A secondary output electrode in the form of a mesh is formed near the end portion of the device (36) on the right side. Only primary input electrodes (1,2) connected to the two inner electrode groups, a secondary output electrode (40), and the lead electrode of the secondary output electrode in the form of a mesh are exposed on the same surface of the device.
