Abstract:
An electronic apparatus includes a switch having contacts spaced from each other. The contacts are designed to independently establish electric connection. A controller unit is designed to instruct the control on an image on the screen of a display panel in the electronic apparatus when the controller unit sequentially detects the electric connection at at least two of the contacts in a predetermined time period. A sequential detection of electric connection at the contacts within the predetermined time period is utilized to effect the control of the image in the electronic apparatus. Facilitated operations can be achieved to effect the control of the image on the screen. Conventional contacts can be utilized to establish electric connection. The control of the image can be accomplished with a simple structure.
Abstract:
A mobile wireless communication device that wirelessly communicates with a base station that provides wireless communication service includes a location information storage unit configured to store a location information, a content storage unit configured to store the content, a history storage unit configured to store history information, a determination unit configured to determine a possibility of transition from a current base station to in an outside zone of the wireless communication service, and an updating unit configured to acquire a content from the location information storage unit by using wireless communication service that is provided by the current base station, so as to update content of the content storage unit, when the determination unit determines that there is a possibility of transition to the state that the mobile wireless communication device is in the outside zone of the wireless communication service.
