A vehicle seat assembly includes a seat frame for supporting a cushion of a seat. A laser component can be coupled to a line generating optic that can create a laser line from an infrared laser spot, wherein the laser component and line generating optic emit a plane of IR light. In this embodiment, a desired performance value indicative of a user’s desired performance level for an electrical device is received. The preparation line may be a high pressure heated conduit, a covered batch conveyer, sealed pocket feeder or similar line, and prepares each component at a temperature and time suitable for the particular ingredient. The first power supply changes the power supply voltage so that luminance of the light emitting layers vary. The driving member preferably is rotatable and is caused to rotate by a magnetic actuator that can be activated by a magnetic field from outside the body.
