Abstract: A device for detecting infrared radiation emanating from a subject while not in physical contact with the subject. The device includes a body, an infrared sensor located in the body oriented to receive the infrared radiation and to generate at least one output that corresponds to the received infrared radiation, an analog to digital converter in communication with the infrared sensor to receive the at least one output, a processor in communication with the analog to digital converter or infrared sensor to process an output of the analog to digital converter or the output of the infrared sensor, into a computed temperature of the subject, wherein the processor adjusts the computed temperature based on an emissivity of the subject, a memory module to store a first plurality of computed temperatures in a predetermined sequence; and a filter module to select a first maximum from among the first plurality of computed temperatures.

Abstract: A method of determining a temperature of a subject while not in physical contact with the subject. The method includes providing an infrared sensor oriented to receive the infrared radiation emanating from a subject and to generate at least one output that corresponds to the received infrared radiation, providing a processor to process the at least one output into a computed temperature of the subject, adjusting the computer temperature based on an emissivity of the subject, the emissivity determined at least in part by a luminance value based at least in part on an image of the subject providing a memory module to store a first plurality of computed temperatures in a predetermined sequence, and selecting a first maximum from among the first plurality of computed temperatures. A display is provided to display the temperature of the subject.
