An order data obtaining device displays a list of components on a Web page, and recognizes components selected on the Web page, thereby obtaining order data of a product that is formed of a plurality of components. The raking attachment comprises a generally triangular shaped top wall, an opposing triangular shaped bottom face, side walls and an inlet throat with the side walls joined to at least a portion of the top wall and the bottom face wherein the top wall, bottom face and side walls extend longitudinally from the inlet throat. When it is determined that the user will be late for the appointment, an attendee notification message is automatically generated using the attendee notification information. Each of the switches responds to a surface temperature of a corresponding one of the heating members so that when the surface temperature exceeds a predetermined value, the electric power is shut off. An output voltage at the light source is measured, and compared to the corresponding voltage of the selected duty cycle to produce a voltage comparison result. The invention also relates to a novel group of compounds of Formula and to methods for preparing compounds of Formula.
