A VSB reception system includes a sequence generator for decoding a symbol corresponding to the supplemental data and generating a predefined sequence included in the supplemental data at VSB transmission system. The device is comprised of at least two surfaces, the first obscuring the second until the vehicle has attained the desired position within the parking space. The free ends of the wire are bent to form a loop which retains an attachment means. The cavities open to a lower surface of the semiconductor chip and extend toward the upper surface to expose the conductive pad on the upper surface.
