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 self-straightening tape measure which is commonly called a convex rule, has hitherto been prepared exclusively of steel, however, the tape measure of steel is not only liable to be rusted but also is dangerous owing to good conductor of electricity when used in the vicinity of electric wires. In order to eliminate the above disadvantages, the present invention provides a self-straightening tape measure of resin, which is prepared by impregnating a tape material of crossing fibers with a large amount of thermosetting resin, bending the tape material in the width direction to form an arc in cross section, so that the arc may occupy from one-third to three-fourths of the whole circumference of the circle described by extending the arc, and heating the tape material to harden the resin and to have the said arcuate form.
