US 7,071,647 B2 · Method and apparatus for detecting a hazard in a moveable electronic member

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.

Dependent claims

An electronic apparatus comprising:

a movable member that is allowed to move in a plurality of sections;
a driving unit for moving the movable member;
and
a controller for controlling the driving unit and for detecting a hazard that occurs during movement of the movable member at respectively different sensitivities in the plurality of sections;
wherein the sensitivities correspond to periods for detecting the occurrence of a hazard, and a period for a section having a higher probability of occurrence of the hazard is shorter than a period for a section having a lower probability of occurrence of the hazard.
