The mark consists of a three-dimensional configuration of the housing of the goods; the housing has a forward extending lower portion having a generally rectangular cross section; a front face of the lower portion has two lower right square openings and an upper circular opening surrounded by a hexagonal protuberance; the rear of the lower portion extends upward to an upper portion having a rectangular front opening that is parallel to the front face of the lower portion; a long axis of the rectangular front opening extends perpendicularly to a longitudinal axis of the lower portion. The dashed lines reflect an internal component within the housing that is visible at the rectangular front opening and forms no part of the mark.
