A system described herein includes a receiver component that receives third party code for execution in a host environment, wherein the third party code corresponds to a dynamic programming language, and wherein the third party code has at least one object reference to a first object that is used by the third party code. Heat is applied a controllable way to the object during a background heating mode, thereby selectively heating the object to at least generally produce a temperature rise throughout the object during background heating. In either example, the top side of the handle of the shaving unit provides a surface for the affixing of a timed water soluble encapsulated material which comprises varying quantities of scent emitting substances. In this way, the puncturing of CQI using ACKNACK can be minimized, with the result that the error characteristic of control information can be prevented from being degraded. The contact prong is provided in the direction of the longitudinal axis with a first stop and a second stop, which acts in opposition to the first stop, for force-fitting engagement of the contact prong with the carrier plate. According to the invention, the control device can be changed over to a cleaning mode in which the functions of the in-motion scale are controlled according to a specified cleaning-mode functional model so that danger to operating personnel andor damage to the in-motion scale is reduced or eliminated.
