(PhysOrg.com) -- A future sensor may take away a patient's breath while simultaneously determining whether the patient has breast cancer, lung cancer, diabetes or asthma. A University of Missouri researcher is developing a device that will analyze breath or urine samples for volatile markers inside the body that indicate disease. These volatile markers, such as alkanes, acetones or nitric oxide, give doctors clues about what is happening inside the body and can be used as a diagnostic tool. http://www.physorg.com/news155938204.html Chemistry Tue, 10 Mar 2009 21:10:27 EST news155938204 Hitachi, Ltd. announced the development of a compact and low cost speed sensor technology for motor vehicles which provides accurate measurement of relative velocity using an mm -wave radar (77GHz band). The technology enables the relative velocity of a motor vehicle to the ground to be measured by beaming millimeter -wavelength radio waves (mm -wave) on to the ground. Compared to conventional wheel -speed sensors which calculate velocity by detecting wheel rotation, the new sensor is able to measure velocity even during braking or slipping when the tires are not rotating. http://www.physorg.com/news143731098.html Technology Mon, 20 Oct 2008 14:18:18 EST news143731098
