A front projection display device is provided including an image-generating source configured to generate an image, a wide angle lens system adapted to receive the image, and a screen. A power return mechanism is operatively coupled to the seat back for automatically returning the seat back from the folded position to the seating position. Processing is performed for the multiple groups of code channels in multiple iterations. When the load voltage exceeds the second voltage, the two-terminal current controller operates in a third mode. Accordingly, since the generator is configured with the reduced number of switches, it can be manufactured inexpensively and simply.
