"At last you can take your baby’s temperature without poking her in the ear, mouth, or even worse places. Thermofocus ($70) uses infrared technology to measure temperature at the forehead in less than a second without ever touching the skin, giving results proven to be as accurate as an ear or rectal thermometer. Since there’s no contact involved, it’s easy to monitor a sick child’s temperature throughout the night without disturbing him." - Neil Bernhart from Bookmarklet
