Patent application numberDescriptionPublished
20080227399Mobile device system and mobile device - Situations such as mobile devices being left in the activated mode are avoided by efficiently reporting the statuses of a plurality of mobile devices.09-18-2008
20080235593Mobile device system and mobile device - When one mobile device is activated, the existence of information which other mobile devices hold is also confirmed. There is provided a mobile device system including a plurality of mobile devices, wherein each mobile device includes a communication unit for communicating with other mobile devices, an information storage unit for storing information, a list storage unit for storing a list of information stored in the information storage unit and in the information storage units of the other mobile devices, a display unit, and a control unit. The control unit displays the list stored in the information storage unit on the display unit and, when information stored in the information storage unit of another mobile device is specified, requests transmission of information from the other mobile device using the communication unit and displays information transmitted in response to the request on the display unit.09-25-2008
20090115879Information management method and digital camera - An information management method and digital camera which can reduce the burden on a user in terms of information management, while ensuring security, are provided. The invention provides a digital camera including an image-acquisition unit for acquiring image information; an ID reading unit for reading identification information of a wireless IC tag built into personal belongings that an image-acquiring person carries; a recording unit for associating and recording the read identification information and image information; a display unit for displaying the image information; and a control unit. At the time of a display request for the image information, the control unit displays the image information on the display unit when the identification information read by the ID reading unit matches the identification information associated with the image information which is the subject of the display request.05-07-2009
20090117848Mobile device system and mobile device - Even when the mobile devices which one carries change from day to day, the invention can flexibly handle such changes to prevent misplacement and the like of a mobile device.
