According to the present invention, the system includes a calibrating light source that emits light energy onto a substrate contained in the thermal processing chamber. A light detector then detects the amount of light that is being transmitted through the substrate. The amount of detected light energy is then used to calibrate a temperature measurement device that is used in the system. | 2010-09-16 |
20100232471 | EAR THERMOMETER CRADLE AND ASSEMBLY THEREOF - The present invention is an ear thermometer cradle and an ear thermometer assembly. The ear thermometer cradle comprises a hollow housing, a swivel arm, a probe cover container seat, a first elastic member disposed between the swivel arm and the hollow house. The ear thermometer cradle comprises a second elastic member between the container seat and the hollow housing. The hollow housing has an opening and a first blocking portion. The swivel arm includes a first pivot on one end thereof for pivotally connected with the hollow housing, a bearing portion on the other end thereof, and a second blocking portion between the first pivot and the bearing portion. The container seat includes a connective device, a second pivot on two lateral sides thereof for pivotally connected with the hollow housing, a third blocking portion and a forth blocking portion engaging with the first and the second blocking portion respectively. | 2010-09-16 |
