A road mat having a mat body with a first coupling end and a second coupling end. The apparatus of the present invention relates to an apparatus for rejecting image signals in a receiver of a direct conversion structure and comprises a signal mismatch compensation unit configured to detect gain error and phase error between an In-phase signal and a Quadrature signal received through the receiver, to reject image signals existing in the I and Q signals, and to output a result. A solution reservoir containing a solution is disposed within the body. The exterior sealing surface of the pre-mold housing member loops around an exterior lateral side of the housing which is between front and rear ends of the housing. State information is maintained across transactions.
