Publication number: 20090187678Abstract: The invention provides a method for a portable electronic device such as a computer to be capable of safely coping with the occurrence of a surprise removal from an external hard disk drive (HDD) connected by wireless. An HDD is connected to a portable computer by wireless via a wireless extension device. First, a wireless communication path between the HDD and the portable computer is configured. Subsequently, a file is read and edited by accessing the HDD from the portable computer. Next, removal information indicating that the portable computer is away from the HDD is produced. The removal information can be produced by detecting an acceleration generated in the portable computer, or by directly detecting the distance by the strength of the wireless signal. Data under editing is saved before occurrence of surprise removal by ejecting the HDD in response to the production of the removal information.Type: ApplicationFiled: January 22, 2009Publication date: July 23, 2009Inventors: Kishiko Itoh, Seiichi Kawano, Susumu Shimotono, Jun Sugiyama, Hidenori Kinoshita

Publication number: 20060182484Abstract: A photo album creating or editing software application transfers a total cover page image to a printer. The total cover page image may include printer commands or printer commands may be transmitted separately. The total cover page image is transferred separately or is transferred in sections, such as a back flap section, a back cover section, a spine section, a front cover section, and a front flap section. The printer receives an indication that a printhead is approaching a fold area of the cover page paper. The printer moves the printhead in response to receiving the indication that the printhead is approaching a fold area. The printer forwards the cover page paper by a pre-determined amendment. The printhead of the printer resumes printing, after the forwarding of the cover page paper.Type: ApplicationFiled: February 11, 2005Publication date: August 17, 2006Applicant: EPSON AMERICA, INC.Inventors: Boping Xie, Rodrigo Catalan, Jun Sugiyama
