An information processing method, an information processing apparatus and a program can prevent errors from arising when associating point group data obtained by actually measuring an item such as a metal part and design data defining the item. A first wall and a second wall are joined at a corner edge. Each component is then sequentially extracted according to density, with a sensor present in the device to control the operation of valves directing the collection of each component. A light source is disposed within the headlamp and electrical communication between the light source and the electrical circuitry of the eyeglass frames is provided by electrical contacts associated with the mounting structures of the headlamp and eyeglass frames. The upper surface of the upper buffer layer and the lower surface of the lower buffer layer are respectively joined to a lead and a base through Pb-free solders having a thickness of not less than 0.
