The mark consists of a three-dimensional configuration of a design of an impact detector device. The broken lines indicate a rectangular-shaped impact detection device incorporating a tube-shaped indicator centrally located on an octagonal carrier which are not claimed as a feature of the mark. The octagonal carrier includes black trapezoidal areas extending from the left and right sides of the indicator to the respective left and right vertical edges of the carrier. Each black trapezoidal area has an upper base that borders the respective left or right side of the indicator, and the legs of the trapezoidal area extend to the lower base of the trapezoidal area where the lower base forms the respective left or right vertical edge of the carrier. The remaining upper and lower portions of the carrier are orange. The white in the center of the mark is used only to depict the dotted-line outlining of the non-claimed elements of the mark and therefore the color white in the center is not claimed as a feature of the mark. The remaining white is background and is not claimed as a feature of the mark.
