The Thermometer Meets the Smart Phone: Technology that Help Moms and Saves Lives
A new patent granted to Fraden Corporation of San Diego, may in the future allow smart phone become an accurate medical diagnosing instrument that, without physical contact, can instantly measure someones temperature and detect environmental hazards. Forbes reports.
There are two ways of taking temperature. One is by contacting the body, like by a tip of an oral thermometer touching under the tongue. The other is a non-contact method by detecting intensity of the invisible infrared light that naturally emanates from every surface in this Universe.
This light is proportional to the surface temperature, so by measuring its brightness a microprocessor can compute the temperature.
... According to the patent, the infrared sensor is positioned inside a smart phone next to the digital camera lens. To measure temperature, the camera works as a viewfinder for a correct positioning the smart phone at about 1 inch from the patient’s temple. When the phone detects that its position is just right, it instantly takes the body temperature with a clinical accuracy sufficient for any diagnostic purpose. Thus, a doctor, nurse or mom no longer needs to carry a thermometer – it will be just there – inside their smart phone.
