Patent number: 11943822Abstract: A communication device is configured to wirelessly connect to an electronic apparatus. The communication device comprises a first communication unit and a second communication unit of a same type as that of the first communication unit and a control unit configured to control the first communication unit and the second communication unit. The control unit is configured to acquire a communication situation of the first communication unit with electronic apparatus and another communication situation of the second communication unit with electronic apparatus. The control unit is configured to execute an allocation process for determining a connection destination of an electronic apparatus to the first communication unit or the second communication unit based on the communication situations.Type: GrantFiled: November 8, 2019Date of Patent: March 26, 2024Assignee: Sony Interactive Entertainment Inc.Inventors: Yoshiyuki Imada, Masashi Kamata, Tai Hirakawa

Patent number: 11849352Abstract: A communication device includes a first communication unit and a second communication unit and is configured to wirelessly connect to an electronic apparatus. The first communication unit and the second communication unit operate in the same communication protocol. The first communication unit is configured to wait for a connection request from the electronic apparatus, and the second communication unit is configured to wirelessly connect to the electronic apparatus from which the first communication unit received a connection request. The first communication unit is configured to wait, where the first communication unit is not connected to the electronic apparatus, for a connection request in a first mode in which a waiting time period is relatively long, and the first communication unit is configured to wait, where the first communication unit is connected to the electronic apparatus, for a connection request in a second mode in which the waiting time period is relatively short.Type: GrantFiled: November 8, 2019Date of Patent: December 19, 2023Assignee: Sony Interactive Entertainment Inc.Inventors: Tai Hirakawa, Yoshiyuki Imada, Masashi Kamata

Publication number: 20220095407Abstract: A communication device is configured to wirelessly connect to an external apparatus. The communication device comprises a first communication unit and a control unit configured to control the first communication unit. The first communication unit is configured to operate as one of a master and a slave. When the first communication unit is connected to a given external apparatus, the control unit is configured to control a period during which the first communication unit operates as the slave in response to a communication situation of the first communication unit with a different external apparatus from the given external apparatus.Type: ApplicationFiled: November 8, 2019Publication date: March 24, 2022Applicant: Sony Interactive Entertainment Inc.Inventors: Tai Hirakawa, Yoshiyuki Imada, Masashi Kamata
