Hand-held medical-data capture-device having detection of temperature by a microprocessor from a signal from a digital infrared sensor on a separate circuit board with no A/D converter and having interoperation with electronic medical record systems to transmit the temperature 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.
