Hand-held medical-data capture-device determining a temperature by a microprocessor from a signal of a digital infrared sensor and detecting vital signs through variation amplification of images and having interoperations with electronic medical record systems to transmit the temperature, vital signs and device information
In one implementation, an apparatus estimates body core temperature from an infrared measurement of an external source point using a cubic relationship between the body core temperature and the measurement of an external source point is described, estimates temperature from a digital infrared sensor and determines vital signs from a solid-state image transducer, or determines vital signs from a solid-state image transducer and estimates body core temperature from an infrared measurement of an external source point using a cubic relationship between the body core temperature and the measurement of an external source point; after which the estimated and/or determined information is transmitted to an external database.
