Abstract: A urine test for diagnosing lung cancer has been developed that uses an artificial nose such as a colorimetric sensor arrays to identify metabolic profiles in urine headspace gas. Cancer cells excrete unique compounds that are a byproduct of their metabolism. The compounds are excreted through a patient's endocrine system by filtration through the kidneys and other organs and are ultimately excreted through the urine. Some of these cancer cell by-products excrete in the urine are small volatile organic compounds (VOCs). Once the urine has exited the body, these VOCs may be outgassed to the environment. Experimental research has determined that a colorimetric sensor array as disclosed is capable of reliably identifying patients with lung cancer based after exposure to the VOCs of the urine headspace gas.

Abstract: An upper respiratory bacterial infection is detected from exhaled mammalian breath by using a colorimetric sensor array having a spectral response characteristic that changes when exposed to bacteria-produced analytes in the exhaled breath. A flow regulating system directs a leading portion of the exhaled breath into gaseous communication with the array to change its spectral response characteristic, and discharges a trailing portion of the exhaled breath exteriorly of the apparatus. A spectral analysis system analyzes the spectral response characteristic changed solely by the leading portion of the exhaled breath, and detects the upper respiratory bacterial infection when the bacteria-produced analytes are present therein. Reactivity of the analytes with the array is increased by advance oxidizing and/or heating the analytes.

Abstract: An image processing apparatus and a control method thereof. Information of image processing parameters, such as halftoning, edge emphasis, color correction, and gamma correction, is inserted into the document to be printed in the form of the watermark during the printing work. Thus, when the user wants to copy the printed document, the information of the image processing parameters used for printing the document is optimized suitable for the copy by detecting the watermark inserted into the printed document, thereby improving the quality of the copy. The method includes inserting first information of image processing parameters, which are used to print the document, into the document when printing the document, and optimizing second information of image processing parameters to be used for copying the document using the first information of image processing parameters inserted into the document when copying the document.

Abstract: A method of controlling an image processing apparatus, and an image processing apparatus to carry-out the method. The edge pixels of a black character may be evaluated to improve visibility of edge pixels and to enhance the blackening of the edge pixels when the evaluated edge pixels are determined to be the actual edge pixels of the original image and to correct the edge pixels to be suitable for original background pixel values and to brighten the edge pixels when the evaluated edge pixels are determined to be the actual background pixels of an original image. The black character may be enhanced so that the actual black character becomes blacker and that the background pixels become brighter to improve the visibility of the black character. The black character may be distinguished from a scanned image, the print thickness of the distinguished black character may be controlled, and the black character having controlled print thickness may be printed out using only a K color.
