Provided is a dual view display panel including: a first vertical cell line, a second vertical cell line, a third vertical cell line, and a fourth vertical cell line. The first and second sub-lens group frames are integrally moved along in the optical axis direction via the focusing mechanism. In an alternate embodiment, a transmitter of limited range is placed at each entrance to the noise sensitive area and the ringer circuit is inhibited upon momentarily receiving the control signal entering the area, and activated upon momentarily receiving the control signal exiting the area. Accordingly, any conformability deterioration that may be caused by a large forward movement of the seat cushion at a seat back taking a large reclining position can be prevented properly. The new enemy force movement predictions can then be compared to the own force mission plan to determine if a route re-plan is needed.
