Abstract: The image correction method and system for navigation device with portable navigation unit converts an image based on projection to a first display into a suitable image on a second display such that the area of the second display is used economically and efficiently while maintaining some elements of the image in substantially common aspect ratio between the images on the first display and on the second display. The image correction method determines the ratio of the second display, determines if image correction is required, and checks a correction table and performs image correction according to correction rules to generate the corrected image for projecting on the second display.

Abstract: A navigation system includes an in-vehicle portion and a removable navigational unit, where the removable navigation unit is a portable device with navigation capability on its own. The removable navigation unit is capable of being connected to the in-vehicle portion through an navigation interface to perform the navigation function in combination with the in-vehicle portion. The removable navigation unit seamlessly integrates with the in-vehicle portion of the vehicle to provide portability of navigation function when used independently from the in-vehicle portion, and taking advantage of the components of in-vehicle portion when used in conjunction with the in-vehicle portion.

Abstract: The invention relates to a conveyor between two drive systems (1 and 2) designed to convey, for example to pedestrians, a movement in a longitudinal direction (L), this device comprising a chassis (3) and means of rolling defining a rolling surface (R). The device according to the invention comprises several side walls each of which is integral to the chassis (3) and extends on a plane perpendicular to the transversal direction (T) as far as an upper edge set back from the rolling surface (R), and several axes (61) each of which extends parallelly to the transversal direction (T) and crosses several adjacent side walls, the means of rolling comprise rollers (4) rotationally assembled to the axes (61) and creating several successive rows, adjacent to the longitudinal direction (L).
