An apparatus that senses temperature from a digital infrared sensor is described. A digital signal representing a temperature without conversion from analog is transmitted from the digital infrared sensor received by a microprocessor and converted to body core temperature by the microprocessor.

The invention relates to an apparatus for measuring the human body temperature. It comprises of an infrared temperature sensor for performing temperature sampling on a plurality MN of sampling points, M3, N3. The temperatures of the sampling points with temperatures within the effective temperature range of the human body are averaged to obtain the body temperature of the human body. By collecting the temperatures of a plurality of sampling points of the measured object, the invention effectively avoids the errors that measurement of single point may produce (as may be caused by factors such as the environment); by screening for temperatures within the effective temperature range of the human body, the invention effectively avoids errors or interference produced by factors such as clothing or the environment. The improved accuracy and real-time measurement of body temperature bring convenience to people's lives.

In some examples, a temperature distribution sensor may include a laser source to emit a laser beam that is tunable over a wavelength range. The wavelength range may be less than a Raman bandwidth in a device under test (DUT), or of-the-order-of the Raman bandwidth in the DUT. A pulsed source may apply a pulse drive signal to the laser beam or to a modulator to modulate the laser beam that is to be injected into the DUT. A bandpass filter may be operatively disposed between the laser source and the DUT, and may be configured to an anti-Stokes wavelength that is narrower than the Raman bandwidth. A photodiode may be operatively disposed between the bandpass filter and the DUT to acquire, from the DUT, anti-Stokes optical time-domain reflectometer traces for two preset wavelengths of the laser beam to determine a temperature distribution for the DUT.

A method of determining a temperature of a patient includes measuring a first temperature of the patient with a temperature device, and measuring a second temperature of an environment with the temperature device. The method includes determining if a change in the ambient temperature exceeds a threshold. If the change does exceed the threshold, the method also includes applying a correction factor to the first temperature of the patient to account for the change in ambient temperature.

A wristwatch device includes a smartwatch having a digital display screen. The watch device also includes biometric sensors and proximity sensors. Furthermore, the watch device is configured to determine the proximity of a person to the watch wearer and display an indication that corresponds to that person's body temperature. Additionally, the wristwatch device may also serve as a panic button which will alert a user when their vital signs and temperature changes rapidly. The system will record a user's vitals and temperatures every hour. In the event of a panic situation, the system will automatically screenshot and record the user's latest temperature and vitals. This information will may be linked to other individuals such as family members.
