Patent number: 11569672Abstract: An electronic device includes a connection unit and a control unit. The control unit enables a power supply path for supplying power from a first battery connected to an external device to the electronic device and enables a power supply path for supplying power from a second battery connected to the external device to a predetermined functional unit of the external device, in a case where the first battery or the second battery connected to the external device is not charged. The control unit disables a power supply path for supplying power from the second battery connected to the external device to the predetermined functional unit and enables a power supply path for supplying power from the electronic device to the first battery or the second battery, in a case where the first battery or the second battery connected to the external device is charged.Type: GrantFiled: April 27, 2021Date of Patent: January 31, 2023Assignee: CANON KABUSHIKI KAISHAInventors: Sho Ichikawa, Kento Inai, Hiroshi Moritomo, Kenichirou Hayashi, Shigeo Aoyagi, Sayaka Kumon, Hirokazu Izuoka, Akira Matsuo

Patent number: 10536298Abstract: There is provided a communication apparatus having a first communication unit configured to hold a first communication parameter and share the held first communication parameter with an external apparatus, and a second communication unit configured to perform communication with the external apparatus by using the first communication parameter that the first communication unit shares with the external apparatus. A control unit performs control so that communication by the second communication unit is started in response to sharing of the first communication parameter by the first communication unit. When communication by the second communication unit is to be performed in response to sharing of the first communication parameter by the first communication unit, the control unit puts the first communication parameter, which has been shared with the external apparatus, in a state in which it cannot be shared via the first communication unit.Type: GrantFiled: June 26, 2015Date of Patent: January 14, 2020Assignee: Canon Kabushiki KaishaInventor: Kenichirou Hayashi

Publication number: 20190281615Abstract: There is provided a communication control apparatus. A control unit performs control such that first wireless communication with an external apparatus is conducted via a first communication unit according to first setting information. In a case where a communication execution instruction about a second communication unit is detected while the first wireless communication is being conducted, the control unit stops the first wireless communication, and performs control such that second wireless communication with the external apparatus is conducted via the second communication unit according to the first setting information. In a case where the communication execution instruction is detected when the first wireless communication is not conducted, the control unit performs control such that third wireless communication with the external apparatus is conducted via the second communication unit according to second setting information.Type: ApplicationFiled: February 28, 2019Publication date: September 12, 2019Inventor: Kenichirou Hayashi
