Abstract: A communication device includes: a plurality of wireless communication sections, each of which is configured to wirelessly receive a signal from another communication device; and a control section configured to perform a detection process of detecting specific elements with regard to a plurality of correlation computation results, each of which is obtained by correlating a first signal that is transmitted from the other communication device and each of second signals at the designated interval and includes a correlation value indicating magnitude of correlation between the first signal and the second signal as an element obtained at the designated interval, and control a change process of treating a wireless communication section having earliest time corresponding to the specific element as a first wireless communication section among the plurality of wireless communication sections, treating the other wireless communication section as a second wireless communication section among the plurality of wireless co

Abstract: A connection structure includes a terminal with an electric wire attached thereto and with an insertion hole, a sheet-shaped conductive member including a cut portion formed by being cut in to be pierced from a front surface to a rear surface thereof, and a rivet swaged while inserting a swaged portion into the insertion hole and the cut portion and rolling together the conductive member of the cut portion to have a conduction between the terminal and the conductive member.
