An engine is provided that includes an exhaust gas recirculation conduit in fluidic communication with a first exhaust valve in a cylinder and an intake system, an exhaust conduit in fluidic communication with a second exhaust valve in the cylinder and an emission control device. In one embodiment, the invention collects acoustic data, develops a three dimensional ultrasound image from the collected acoustic data, renders the ultrasound image on a display, modifies selected portions of the acoustic data, and displays the modified acoustic data in the form of a highlighted region on the rendered ultrasound image, wherein the highlighted region defines an included volume. Receiving a call, the central communication network simultaneously routes the call to a plurality of pre-programmed numbers on the PSTN and on the IP network. The users in the foreign domains need not have a direct relationship with the transit domains. When the sensor detects one of the touch and the approach of the user at the input device, the image display device displays a predetermined image concerning the input device on a display screen. Accordingly, alignment margin of the contact hole to be formed next to the capacitor can be reduced.
