Patent number: 10386455Abstract: A position detection system performs first through third processes to measure, using high-frequency signals, a position of a slave device in a measurement area surrounded by parent devices. The first process measures distances between the slave device and each of the master devices a plurality of times, to obtain a minimum value of each of the distances. The second process obtains a position of an intersection point of two arcs among arcs respectively having the minimum value of each of the distances as a radius from respective centers of the master devices when a number of intersection points of the two arcs within the measurement area is one. The third process regards a center of gravity of the intersection points as a true position of the slave device when the intersection points are densely arranged.Type: GrantFiled: September 11, 2018Date of Patent: August 20, 2019Assignee: ALPS ALPINE CO., LTD.Inventors: Keigo Wakana, Daisuke Takai, Yukimitsu Yamada, Toshiki Nakamura, Hironori Takayama
