Abstract: A rear view system for a transportation device includes a rear view means, a sensor and a controller. The sensor is used for generating a movement signal according to the movement of the transportation device. The controller is used for controlling the rotation of the rear view means according to the movement signal. Moreover, a method for adjusting the visual angle of a rear view means equipped in a transportation device is also disclosed.

Abstract: A magnetic boot module is described. The magnetic boot module has a pair of magnetic boots, a pair of moving devices, and a magnetic inductive path. Each of the moving devices couples to one of the magnetic boots to transversely push the magnetic boots moving on the magnetic inductive path step by step. The magnetic inductive path is formed on a magnetic inductive plate or a magnetic inductive rail. The magnetic boot module further utilizes a position detecting device to sense a current position thereof.

Abstract: The present invention provides for improved rearview mirror device for the use. Rearview mirror device of the present invention is likely to be particularly useful in ground vehicle, such as car or truck for better driving view since it automatically modifies the angle to provide a safety-view for driver during the vehicle turning. In one preferred embodiment, an automatic mirror angle modifying device comprises: a rearview mirror, which is supported on a vehicle body; an shaft rotation measurement device, which further includes a ring apparatus which surrounds the steering wheel shaft and a ring apparatus decoder; a microprocessor and a motor. While the steering wheel is rotating to indicate to vehicle body turning, the measuring device detects the shaft rotation angle. Then, according to the rotation angle, the microprocessor computes the best rear view angle and informs the motor to drive the mirror to an adequate position.
