Abstract: Described herein are embodiments of systems and methods that utilize temperature measurements taken with head-mounted sensors as well as images of a user's face to detect fever and/or intoxication. One embodiment of a system to detect fever includes a first head-mounted temperature sensor that measures skin temperature (Tskin) at a first region on a user's head, a second head-mounted temperature sensor that measures a temperature of the environment (Tenv), and a computer. The computer receives images of a second region on the user's face, captured by a camera sensitive to wavelengths below 1050 nanometer, and calculates, based on the images, values indicative of hemoglobin concentrations at three or more regions on the user's face. The computer can then detect whether the user has a fever based on Tskin, Tenv and the values.

Abstract: Various embodiments include an electronic circuit for driving a thermocouple element comprising: contact electrodes for connecting cold-end electrodes of the thermocouple element; and a measurement circuit to measure a thermo-voltage generated by the thermocouple element. One of the electrodes is connected to a supply voltage and a ground potential over a voltage divider having resistors with pre-defined resistance values such that a common mode voltage between the contact electrode and the ground potential is in a pre-defined range. If a leakage resistance effective between the contact electrode and the ground potential is greater than a pre-defined threshold, a processor compares the common mode voltage to the pre-defined range and generates a calibration value for the measurement circuitry if the common mode voltage is outside the range.

Abstract: Apparatuses and methods for in-situ temperature measurement of a process chamber are described herein. A process chamber includes an infrared (IR) sensor mounted to the chamber wall. The IR sensor is mounted such that it can be oriented to receive an IR wave from targets within the process chamber through a view port in the chamber wall to detect a temperature of a surface inside the chamber, or to receive an IR wave from a target outside of the process chamber to detect an atmospheric temperature or a temperature of an exterior surface of the process chamber. As the orientation of the IR sensor is controllable to receive the IR wave from selected directions, it may be used to detect the temperature of various targets inside and outside the process chamber. The obtained temperature information is useful to improve overall chamber matching, processing throughput, and uniformity.
