1. 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;

    a single button operable coupled to the microprocessor;

    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, the infrared signal acquired from a forehead of a user and detected by the digital infrared sensor, and the microprocessor is further operable to determine the temperature from the received digital signal by using the PWM,wherein a connection is established by the wireless communication subsystem to an external device and data is pushed from the non-touch thermometer through the wireless communication subsystem, thereafter the external device controls flow of the data between the non-touch thermometer and the external device, wherein the connection further comprises an authenticated communication channel.
