| 20110216806 | EAR THERMOMETER WITH EAR CANAL SENSING DEVICE AND MEASUREMENT METHOD THEREOF - An ear thermometer with an ear canal sensing device and a measurement method thereof is disclosed. The ear thermometer mainly comprises two sensors. One is an approach sensor installed on a probe. The approach sensor used as the ear canal sensing device determines whether the probe is inserted into an ear canal. Also, the approach sensor is used as the basis to switch the measurement mode to an ear temperature mode or a second measurement mode, such as the forehead temperature mode, surface temperature mode, or room temperature mode. The other is an infrared sensor used to measure temperatures. After the approach sensor determines the measurement mode, the infrared sensor measures the temperature to obtain a signal. Then, the signal is processed through a control module to be shown on a display unit. | 09-08-2011 |
