A self-help oil changing apparatus includes a nozzle having an outer tube in which an oil suction tube and an oil filling tube are received. The image processing apparatus is capable of effectively performing the red eye correction processing by simple manipulation and outputting an image of high quality without a red eye effect in high productivity. The modules also allow for the monitoring of SERS signals emanating from analyte which have accumulated on the confined SERS-active substrates. Similarly, relatively high resolution communication protocol can be processed by the ADC by enabling sufficient pipelined stages to provide a higher resolution. The networked electronic devices may be connected to a computer network for various network services such as, for example, network advertising and software downloading or uploading.
