Patent number: 10810301Abstract: The information processing device includes a registration information obtaining unit, a data generating unit and a transmission processing unit. The registration information obtaining unit obtains user identification information, a login password, and attribute information in association with one another as user registration information. The data generating unit generates incomplete attribute information and complementary attribute information such that the attribute information can be reconstructed by combining the incomplete attribute information and the complementary attribute information with each other. The transmission processing unit transmits the user identification information, the login password, the incomplete attribute information, and the complementary attribute information to another information processing device.Type: GrantFiled: October 28, 2014Date of Patent: October 20, 2020Assignee: Rakuten, Inc.Inventor: Ryosuke Sakai

Patent number: 10790547Abstract: A control module is arranged in alignment with a battery module in a longitudinal direction. The control module includes a busbar, a switch and a current sensor configured to detect electric current flowing through the busbar. The current sensor includes a magneto-electric transducer and a magnetic field suppressor. The magneto-electric transducer is configured to convert a magnetic field, which depends on the electric current flowing through the busbar and passes through the magneto-electric transducer along a plane perpendicular to a height direction, into an electrical signal. The magnetic field suppressor is configured to suppress external magnetic fields from passing through the magneto-electric transducer along the plane perpendicular to the height direction. The switch includes a pair of magnets that are magnetized and opposed to each other in a lateral direction perpendicular to both the longitudinal and height directions. The current sensor is aligned with the magnets in the longitudinal direction.Type: GrantFiled: May 10, 2018Date of Patent: September 29, 2020Assignee: DENSO CORPORATIONInventors: Takahiro Soki, Takashi Inamoto, Ryosuke Sakai, Takeshi Tsukamoto
