Disclosed herein are systems, methods and apparatus, for detection and identification of analytes in a volatilized or volatilizable sample, using the mobility-based signature that is produced when the volatilized sample is passed through a differential ion mobility spectrometry device. A device comprises an articulating main body having a stationary first body, an articulatable second body, and coupler having a mounting member and an articulation link member configured to articulatively couple the second body to the first body. The method comprises the steps of providing a design corresponding to a human body portion having pre-determined colors, the design defining interstices at locations in the design corresponding to pre-determined body part segments and disposing within the interstices cosmetic and personal care containers of a pre-determined color or shade complimentary with the pre-determined body part segment. Start and stop devices are manipulated by a player, and a controller determines whether the specific stop state is to be permitted and a predictive display mode based on the result of the determination. In particular, polarization is produced in each of the micelles with the use of a cation having an ionic radius larger than that of a metal ion at least when the secondary particles are synthesized in the micelles. The received input data is buffered if the serial output paths are in use.
