Publication number: 20190190586Abstract: Upon reception of ACK via a communication IF, an allocator allocates a channel of a repeater to be controlled to communications between wireless terminals. A determination unit determines whether channels allocatable to the communications between the wireless terminals are short. When the determination unit has determined that the allocatable channels are short, a switching controller controls at least one repeater, among repeaters to be controlled by a repeater controller, that serves as a controlling repeater to cause the repeater to transmit, to a wireless terminal standing by in the channel of the repeater, a switching signal designating standby in a channel of a repeater that is controlled by another repeater controller.Type: ApplicationFiled: July 28, 2017Publication date: June 20, 2019Inventors: Yoshiyuki TANAKA, Tatsuya OKA

Patent number: 10315521Abstract: A vehicle power supply system is provided for an electric vehicle. The vehicle power supply system has a first relay and a second relay, which are two-contact movable relays that connect/disconnect a high voltage circuit. The first relay has a first movable contact that is arranged to move with respect to a first fixed contact in a first direction when connecting/disconnecting. The second relay has a second movable contact is arranged to move with respect to a second fixed contact in a second direction when connecting/disconnecting. The second direction is opposite to the first direction. One of the first and second relays is oriented such that its movable contact separates from its fixed contact in a direction in which the greatest acceleration input is applied at the time of a collision.Type: GrantFiled: June 13, 2014Date of Patent: June 11, 2019Assignee: Nissan Motor Co., Ltd.Inventors: Kouji Kato, Shigeyuki Kiyota, Yoshiyuki Tanaka, Toyoki Iguchi, Hiroaki Saitou
