Disclosed herein is a wiper lever assembly which is configured to prevent detachment of end cover members, which includes a lever member gripping a rubber blade disposed thereunder, and an end cover member which covers an end of the lever member from above and which includes claws formed on both lateral sides thereof. The optical and electro-optic components of the camera module are hermetically sealed within a first housing. The method may further include using GPS data or signals transmitted from one or more base stations to determine the position of the apparatus. Still further, the method includes decomposing the signal into a in-phase magnitude component and a in-phase phase component while decomposing the Q signal into a quadrature magnitude component and a quadrature phase component.
