Claim One:
1. 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.
