A navigation system includes a lane information acquiring unit 27 for acquiring both the number of lanes of a road which forms an intersection, and lane information which defines a road branching off from each of the lanes, a lane direction determining unit 28 for determining the direction of each of the lanes on the basis of both the lane information acquired by the lane information acquiring unit, and a road attribute of an incoming road coming into the intersection and a road attribute of an outgoing road extending from the intersection, the road attributes of the incoming and outgoing roads being included in map data acquired by a map data acquiring unit, and a lane information display unit 29 for displaying the direction of each of the lanes determined by the lane direction determining unit with an arrow.

A display apparatus includes an LCD panel, a PCB assembly placed behind the LCD panel and supplying electric current to the LCD panel, an LCD frame provided around the LCD panel, a plurality of first combining parts formed on peripheral sides of the LCD frame, and a plurality of second combining parts formed on the plane of the LCD frame. A front cover is placed in front of the LCD panel, covering edges of the LCD panel and is combined to one of the first and second combining parts. A rear cover is placed behind the LCD panel, accommodating the PCB assembly, and is combined to the other one of the first and second combining parts. With this configuration, the present invention provides a display apparatus which minimizes a space for installation, carriage and storage, has a slim and compact appearance, and prevents an illusion that a display part of an LCD panel is relatively small. Further, the present invention provides a display apparatus which need not comprise some components such as a panel supporting member and a PCB cover, thereby being easily and quickly assembled. Furthermore, the present invention provides a display apparatus of which front and rear covers are made of a conductive metal, so that an LCD panel and a PCB assembly are effectively protected from EMI.

The invention provides a method for designing a special lens of a rearview mirror of an automobile. The method comprises the following steps of: a, using a plane mirror as a designed initial prototype lens; b, designing a special lens outline and an installing position according to a use environment, testing and regulating the design by using the prototype lens; c, based on the outline and position design, referencing an image of the prototype lens to relevant regions behind the automobile for dividing visual regions; d, dividing based on the outline, the position and the visual regions, calculating and testing a curvature and an inclination of each visual region and making a new prototype lens according to the curvature and inclination of each visual region; and e, ending the design when the new prototype lens reaches the design requirement of the prototype lens, and otherwise, returning to the step b for regulating the design. According to the method for designing the special lens, provided by the invention, a plurality of visual regions can be formed on one lens through changes of the positions, the size, the curvature and the inclination, so that a plurality of blind regions of the single-curvature lens can be eliminated, the view field of a driver is effectively enlarged; and meanwhile, due to smooth connection among the visual regions, images in all visual regions are naturally continuous, jump, excursion and boundary of the images among the visual regions on a mirror surface are avoided causing illusion to a driver.

A mirror structure permitting an undistorted view of the blind spots of a vehicle include a first lens module and a second lens module. The first lens module is mounted on an A-pillar of a vehicle and located outside of the vehicle; the second lens module is opposite the first lens module and mounted inside of the vehicle on the A-pillar. The first lens module focuses light beams which would otherwise be blocked by the A-pillar of the vehicle and transmits the light beams to a front windshield of the vehicle, the light beam passing through the front windshield to reach the second lens module, the second lens module diffusing the light beams into the vision of a driver.

The invention relates to a method for a pilot to overcome space unorientation and delusions. The method comprises the steps as follows: 1) according to a law that a celestial body changes along with time, establishing a database file of time and reference coordinate, which are corresponding to a celestial body target space coordinate position; 2) after the takeoff of an aircraft, acquiring the space coordinate of the aircraft via a space locator; 3) determining the direction and the gesture of aircraft via an electric compass and a spinning top; 4) offering time information via a time controller; 5) transferring the reference coordinate and a celestial body object coordinate position in the current database file via the time information; 6) calculating the relative positions of the current celestial body object target space coordinate and the a reference coordinate point according to the direction and the gesture of the aircraft; 7) determining the direction and the gesture of the aircraft of the electronic compass and the spinning top; 8) determining whether the viewing field of the celestial body is displayed by a display or not according to the direction and the gesture of the aircraft; 9) displaying the space coordinate and the celestial body target position under the conditions of the direction and the gesture of the aircraft; and 10) returning to the Step 2). According to the invention, traffic accidents are avoided.
