Patent number: 9888436Abstract: A wireless communication apparatus comprises: a search unit; a determination unit; and a wireless connection processing unit. The search section carries out an SSID (network identification information) search for at least one wireless communication device that has an access point function via a wireless communication section. The determination unit determines, among SSIDs found as a result of search, an SSID that disappeared from the search target of the wireless communication section and has appeared again after disappearance. The wireless connection processing section recognizes, as a connection target device, the wireless communication device corresponding to the determined network identification information, and performs processing for wireless connection to the connection target device. The user operates an operation unit in accordance with the instruction of the guidance screen of the wireless communication apparatus to turn a soft access point OFF and thereafter ON.Type: GrantFiled: July 7, 2016Date of Patent: February 6, 2018Assignee: Seiko Epson CorporationInventors: Yohei Ogawa, Kenji Sakuda

Publication number: 20170036665Abstract: After an alkaline secondary battery is determined to be in an over-discharge state, a battery pack is discharged while an electrolytic solution contained in the alkaline secondary battery in the over-discharge state is decomposed so that traveling using power of a motor is performed. The electrolytic solution remains in the alkaline secondary battery even when the alkaline secondary battery is in the over-discharge state. The alkaline secondary battery in the over-discharge state can be discharged and a vehicle can be allowed to travel by decomposing the electrolytic solution. In this manner, a traveling distance available during evacuation traveling of the vehicle can be increased.Type: ApplicationFiled: March 10, 2015Publication date: February 9, 2017Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Keiichi Minamiura, Hikokazu Akimoto, Yohei Ogawa
