  • Method and apparatus for detecting a hazard in a moveable electronic member
    Patent number: 7071647
    Abstract: A navigation apparatus has a movable face that is allowed to move bidirectionally between a retracted state and an extended state. A range of movement of the movable face is divided at a predetermined position, so that the movement of the movable face has an initial extending stage or initial retracting stage, and a stage subsequent to the initial extending stage or initial retracting stage. A controlling system for driving and controlling the movable face moves the movable face at a lower speed in the subsequent stage than in the initial extending stage or initial retracting stage. Furthermore, a hazard detecting time for the subsequent stage is chosen to be shorter than a hazard detecting time for the initial extending stage or initial retracting stage. Accordingly, the movable face is moved quickly and smoothly in the initial stage while improving safety in the subsequent stage.

  • Electronic apparatus and method of detecting hazard for movement
    Publication number: 20050134208
    Abstract: A navigation apparatus has a movable face that is allowed to move bidirectionally between a retracted state and an extended state. A range of movement of the movable face is divided at a predetermined position, so that the movement of the movable face has an initial extending stage or initial retracting stage, and a stage subsequent to the initial extending stage or initial retracting stage.
