Hand-held medical-data capture-device having a digital infrared sensor with no analog readout ports and optical detection of vital signs through variation amplification and interoperation with electronic medical record systems without specific discovery protocols or domain name service

A device to measure a temperature of a human, the device comprising:

• a microprocessor;
• a battery operably coupled to the microprocessor;
• a camera operably coupled to the microprocessor and providing at least two images to the microprocessor;
• a digital infrared sensor operably coupled to the microprocessor, the digital infrared sensor having only digital readout ports, the digital infrared sensor having no analog sensor readout ports;
• and
• a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the temperature of the human,
• wherein the microprocessor is operable to receive from the digital readout ports a digital signal that is representative of an infrared signal detected by the digital infrared sensor and the microprocessor is operable to determine the temperature of the human from the digital signal that is representative of the infrared signal and the microprocessor including a cropper that is operable to receive the at least two images and operable to crop the at least two images to exclude a border area of the images, generating at least two cropped images, the microprocessor also including a temporal-variation-amplifier of the at least two cropped images that is operable to generate a temporal variation of the at least two cropped images, the microprocessor also including a vital-sign generator that is operably coupled to the temporal-variation-amplifier that is operable to generate at least one vital sign from the temporal variation,
• wherein the device does not support specific discovery protocols or domain name service.
