Hand-held medical-data capture-device having variation amplification and interoperation with electronic medical record systems

A non-touch thermometer to measure a temperature, the non-touch thermometer comprising:

• a microprocessor;
• a battery operably coupled to the microprocessor;
• a single button operably coupled to the microprocessor;
• a camera operably coupled to the microprocessor and operable to capture at least two images to a memory;
• wherein the microprocessor includes a pixel-examination-module that is operable to examine a plurality of pixel values of the at least two images in the memory, a temporal-variation module that is operable to determine temporal variation of the plurality of pixel values between the at least two images, a signal processing module that is operable to amplify the temporal variation resulting in amplified temporal variation, and a vital-sign generator that is operably coupled to the signal processing module that generates at least one human vital sign from the temporal variation;
• wherein determine temporal variation of the plurality of pixel values between the at least two images further comprises:
• identifying pixel values of the at least two images that are representative of skin, resulting in identified pixel values;
• applying a first frequency filter to the identified pixel values, yielding frequency filtered identified pixel values of the skin;
• applying spatial clustering to the frequency filtered identified pixel values of the skin, yielding spatial clustered frequency filtered identified pixel values of the skin;
• applying a second frequency filter to the spatial clustered frequency filtered identified pixel values of skin, yielding the temporal variation;
• a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the at least one human vital sign;
• and
• a display device that is operably coupled to the microprocessor that displays the at least one human vital sign.
