First Claim
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.

Abstract
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.
