Patent number: 8726096Abstract: A controller and a control method for a controller can simplify application development and can improve the performance of device control processes. When a request is received from an application 1 and the received process request is an initialization request, whether or not the received request is the first initialization request received after the application 1 started running is determined. If the received initialization request is the first initialization request, the request is passed to the device driver 3 and initialization settings information describing the configuration of the device driver 3 after the initialization process ends is stored. If an error has occurred in the device driver 3 when the device driver 3 status is detected, an error handling process is executed according to the device driver 3 state. When the device driver 3 has recovered, a request for setting the device driver 3 state to the state based on the initialization settings information is asserted.Type: GrantFiled: May 6, 2013Date of Patent: May 13, 2014Assignee: Seiko Epson CorporationInventors: Nobuhiro Nishimura, Toshihiro Hagiwara, Eiji Ito, Atsushi Sakai

Patent number: 8601563Abstract: An encrypted ID takes as its initial value a tag ID that constitutes an original ID of a wireless tag, and is encrypted using an encryption key each time an ID inquiry is received from a reader/writer. Another encrypted ID also takes the tag ID as its initial value, and is encrypted using an encryption key each time an ID inquiry is received. The wireless tag gives confidential variability to the ID by transmitting a combination of the encrypted ID and the another encrypted ID in reply. The reader/writer can obtain the original ID merely by decoding the two encrypted values until they match, and the decoding load does not increase even if the number of wireless tags that are reading targets increases.Type: GrantFiled: February 15, 2006Date of Patent: December 3, 2013Assignee: Fujitsu LimitedInventors: Atsushi Sakai, Koken Yamamoto, Masahiko Takenaka
