Abstract: A driving assistance system includes an illumination apparatus and a controller. The illumination apparatus is configured to draw an avoidance pattern PTN on a road surface such that it indicates a lane in which the driver's vehicle is to travel or a direction in which the driver's vehicle is to travel. Upon detecting, by a sensor or communication, an obstacle in front of the driver's vehicle, the controller instructs the illumination apparatus to draw the avoidance pattern PTN.

Abstract: A fixing belt includes a base member containing a metal, a sliding layer containing a filler and formed on a base member inner side, and a separation layer formed on a base member outer side. Assume that (i) a sliding layer cross section is obtained by cutting the sliding layer along a sliding layer thickness direction and is divided into sections each having a length that is the same as a sliding layer thickness in a direction perpendicular to the thickness direction, and (ii) a ratio of a filler area to a sliding layer area in each cross section sections is an area ratio. A period coefficient is calculated using the formula (Ave %?Min %)/Ave %, where an average of area ratios of filler areas in all the sections is Ave % and a minimum of the area ratios is Min %, and the calculated period coefficient is 0.6 or more.

Abstract: An axial displacement estimation device estimates an axial displacement angle of a radar apparatus mounted on a mobile body. The axial displacement estimation device uses a plurality of detection values acquired by mutually different plurality of modulation methods to estimate an axial displacement angle for each of the plurality of modulation methods. The axial displacement estimation device determines whether a predetermined allowable condition is met based on a plurality of axial displacement angle estimation results estimated using a plurality of detection values corresponding to respective plurality of modulation methods. The axial displacement estimation device utilizes at least one of a plurality of axial displacement angle estimation results when determined that the predetermined allowable condition is met.
