Hand-held medical-data capture-device having a digital infrared sensor with no A/D converter and having interoperation with electronic medical record systems on a specific segment of a network

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

• a microprocessor;
• a wireless communication subsystem that is operably coupled to the microprocessor and that is operable to transmit a representation of the temperature;
• a battery operably coupled to the microprocessor;
• and
• a digital infrared sensor operably coupled to the microprocessor with no analog-to-digital converter operably coupled between the digital infrared sensor and the microprocessor, the digital infrared sensor having only digital readout ports, the digital infrared sensor comprising a low noise amplifier, an analog-to-digital converter, a digital signal processor, and a pulse width modulator (PWM) in a single industry standard package;
• wherein the digital infrared sensor is configured with no need for recalibration after an initial factory calibration with an emissivity range from 0.1 to 1.0,
• 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 from the received digital signal by using the PWM.
