  • Patent number: 11967160
    Abstract: Conventionally, a method in which pieces of point group information for use in position matching between a white line position detected by an object detection sensor and a white line position on a map are extracted from the white line positions according to a travel environment, has not been taken into account. In the present disclosure, a point group extraction condition is changed according to change in the travel environment so that: a process of position matching that exhibits robustness with respect to change in the travel environment can be realized; and an own position and a white line position existing at a long distance from an own vehicle can be detected with high accuracy.

  • Patent number: 7977222
    Abstract: Doping with suppressed filament deterioration can be performed even in the case of doping in various conditions with an ion doping apparatus having a filament. After ion doping is completed, supply of a material gas is stopped and hydrogen or a rare gas is kept to be supplied. After that, current of the filament is decreased and correspondingly, filament temperature is decreased. Accordingly, in decreasing the filament temperature, the material gas around the filament has been replaced with hydrogen or a rare gas.
